Filament for 3d printing standard piston engine stuff

Blend nylon, polycarbonate, polyester, weather proof cable (pretty sure it is Polyphenylene sulfide & or thermoplastic polyamide) & trash can polypropylene. Blend in only glass blender that is strong but cheap & has blades that are very sharp but typically like to smash things in the side walls of the blender.

From there is has to be mixed together in another "blender" it's not grinder or blender though. Its a "sand blaster blender" 2 or 3 inputs of a sandblaster full of the ceramic, metal, & the plastics in an argon environment that sucks the polymers together with the metal back in & then accelerates (fires) them into each other at high velocity. Everything must be dry, extremely dry & grounded. Or made to be positively charged in the cone shaped vacuum separator like design. So saw dust vacuum separator will work for this & it's metal. But they can be expensive, it depends on what you want to do & make, me & others.

After rock polishing with large (semi I guess) medium & very small hardened steel ball bearings, make sure I get (or anyone else) micron sized nickel, selenium, zirconium, molybdenum, & silicon

Also these ceramics need to be bought & rock polished. These are all high strength & hardness ceramics that are sucky to deal with. But "polishing" them just means breaking off tiny small chunks to get them fairly uniform & to make them slightly charged. But it must be done at then end because you are, very likely, going to ruin your rock polisher if you didn't electroless boron nitride coat/plate them.

Caswell Inc is a great place to buy the playing kit for boron nitride. They even have an app for your phone.

Boron carbide, zirconia- alumina, silicon carbide. Cubic boron nitride can help as well.

During the "blending stage" (hopefully you played the inside of the cone drum thing otherwise this will absolutely destroy it & wear it away hard) you are going to make sure to go to smaller & smaller sizes of the cone & faster & faster speeds of travel for the plastics, metals, and ceramics. If you started out with a very large vacuum saw dust separator it will be harder from here but you can place smaller ones inside. This means it can act as a cascade onion "blender" all in one. Which is cool!

But most of us can't do that... So instead it's fine to start small & just go with a cut up big plastic trash can then work your way down, for what it is worth.

From here it's melting everything with the right ratios. Depending on what you want your ratios will massively change results. This is for the whole engine block & case & head. Like a small single cylinder 4 stroke that's maybe no more than a 125cc. I recommend just sticking to 75cc to make it easier to print everything.

The plastics are even blend, so that means equal parts & there are 5 total so 20% for each. Nothing fancy there.

The metals are different, so harder sadly. You want mostly nickel, you will never go above 89% for the metal ratios. So to make it easy, 75% is a great starting point. That leaves only 25% left for 2 other metals, 1 metaloid, & a non-metal. Zirconium & molybdenum are annoying, seriously & they tend to be expensive! So this means they have the greatest total out of that 25%! *Sarcastic* yay! You can get away with less in other areas but it's hard to blend that all in one spool & soooo...nah. make multiple but honestly who had the time for all this so it's probably easier to just blend it all together for one run.

Split zirconium as a 15% & molybdenum as a 5% which is a lot. Subtract 20 from 25 & you get 5% left over. Although that's because the ceramics & plastics are going to bond chemically with these metals to make this work together, later. Whole thing.

So 5% left now. Selenium & silicon, silicon is 1.5%, yes a harder number to work with by gram weight, but doable. The rest is selenium. 3.5% of selenium added in by weight.

Next are ceramics. Ceramics are annoying as well, sadly. These bastards have no even numbers! For their ratios to each other at all! So be prepared, just saying. Which we will get to the ratios of metal powder (that is already ratio'd as a total whole weight) & the plastics (that are already ratio'd as a total whole weight) later for the 3 coming together in the final ratio needed. Ceramics first.

3 ceramics or if you want 4, but boron is in 2 & so it has to be changed for that blend as there is already silicon & zirconium in the metal blend. Which makes it tougher to do this. The zirconia-alumina (yes if you Google high strength & hardness ceramics you get these, just so happens they work well together for this application & really I like the coincidence honestly) is a semi-majority. Its 40.3362% by weight.....

Yup.

Its actually super important to go 4 decimals. So large weight is needed to make it easier on everything. Who the hell is measuring nanograms, not me. Or micrograms for that matter. Milligrams are hard too, but actually doable with relatively cheap scales you can buy on Amazon even. But f those other snaller grams. Nope, not doing it.

Boron carbide is 5.0522% and silicon carbide takes up the rest. Which is 100% - 45.3884% & that works out to 54.6116% of silicon carbide.

Now, if you want to use some cubic boron nitride you can put together a ratio like this to start off with instead. Zirconia-alumina is 32.5632% boron carbide & cubic boron nitride works to 25.4363% & the rest is silicon carbide, so 42.0005%.

Which....kinda sucks. But larger weight totals make it much, much! Easier.

Now the ratios of the plastic, metal, & ceramics combined. They are not easy non-decimal numbers. So, doing that again. Plastic is 40.2361% the metals are 26.1212% the rest is ceramics for a 33.6427% by weight.

The majority is still plastics, polymers. Ish. Kinda, not really. Most is metal & ceramics. But it needs to be heated together & squeezed & extruded through a nozzle to make a filament.

So, sandblasters have a tungsten carbide nozzle that you can electroless boron nitride plate. Which works. But diamond would be better, however who had the money. Geez. There are 1.75mm opening coolant holes tungsten carbide rods that you can buy that are straight pass through rods, somewhat expensive but not terrible.

Playing them is also not terrible. It makes it last significantly longer. You must keep a very, very consistent ratio throughout this & it likes to separate easily, which is the worst. So no vibration feeding or auger feeding can be done. There needs to be a cone that feeds to the rodz funnels are great. If you could find one the right size.

So instead this is the best & only way to actually do this, but it's a "suck it up and just do it stop complaining to yourself" way. You need to evenly spread this out with a non-separated ratio of everything & squish it with a lot of heat. Like with a T-shirt logo press. Or with something quite similar to this. One plate is not done. Not above 500c & not below 380c! This will destroy bonds and or not adhere. The pressure is at least 100 psi no more than 500psi. The higher you go the worse performing it gets past a point but depending on how dry it is, if you got ratios right if you had more static that day even to if you mold released or not all of it will change total pressure. Practice, but remember I & we don't need it perfect I have stuff below to help remove this inaccuracy & inconsistency to make sure it is good at the end.

Make several, you aren't perfect so it won't be perfectly blended. Its okay I have a way around that. Get a heated roller. Think making pasta & the rollers are heated. That's what that is. Which means you can get your stainless steel pasta roller & electrically resistively heat it after ceramic coating it to make sure it doesn't zap you & you are good to go! 👍

From here you squeeze the plates to a thinner plate, 3mm if you can do it. 1mm is great too. No more than 5mm because they suck to break and snap apart which is what I & anyone else following along needs to do. Get out a soldering iron, yup. You need a SOLDERING IRON!!!

So after you get that out you will "score" a grove into the new sheet you just created & "break it" apart after letting it cool. DO THIS IN A WELL VENTILATED ROOM & OR OUTSIDE!!!! Please, your lungs will die sooner than you wanted & replacements are hard to find. Make sure to use respirators (air filters strapped to your face) & gloves (nitrile works) & a fume hood with a great air filter for the off gassing that occurs. Activated charcoal (carbon) with a great particle filter filter, meaning two different filters. A percolation setup as a pre-filter stage works too, water is fine as long as it is distilled & deionized. Percolation means your (sticky icky) favorite past time filter. Lol, or just anything that allows for a tube to go underwater & have air sucked through & it bubbles up through it. No worries ☺️.

Now after you make sure you have those, you cut the sheets into strips after breaking them after they cool & or heat cut them. From there you will roll them in a vacuum in the long ways fashion, make sure your strips are wide enough to do this! Then flatten them in the roller in the vacuum.

Amazon doesn't have vacuum boxes big enough! So instead I & you can make a vacuum pump do work for us. A sandblaster cabinet can be modified to have structural corners added with light epoxy & or welding done. I recommend welding with a basic spot welder because you only need a plate steel that is 3-5mm thick at corner angles & arches from those to the longer flat sections.

Think a round box inside the box. This allows for the flat parts of the sheet steel to be supported by the plates & the corners so when it tries to collapse it actually pushes against the pressure & uses stronger material to accomplish this. Bolting them in after drilling them epoxying them down is another great way to get this accomplished if you don't know how to weld. It work just as well too!

After you made your huge vacuum chamber that has little arm holes already in it with the gloves provided that can handle abrasion & heat & all that already, because sandblaster cabinet, remember that pressure is different & wants to work it's way into it.

So, you need to significantly epoxy & or bolt more bolts down on your gloves to seal them & prevent vacuum leaks. The gloves are likely thick enough to not burst if they are halfway decent. If not fiberglass & or kevlar can work as a fabric you place over the gloves to make sure they won't break. You just need to bolt down the fabric to the cabinet where the gloves are bolted in & sealed too.

After you make you vacuum cabinet. Steps above. You can now roll the polymer "rug" strips flat & then fold them & proceed again. Vacuums don't have convection cooling. So flatten & fold. Then on to the next one. Do this to all of them first, which is why I had you read that you can make multiple together at once.

The heat of the roller needs to never be above 500c & below 380c! This is extremely important! It destroys bonds & makes it likely that much of it won't adhere together later. Crumbles suck! Remember the psi problem too.

Keep the vacuum pump vacuum pumping. This gets rid of volatiles & off gassing that can contaminate the polymers & or metals/ceramics.

After you complete all strips to folded (just once in half is fine) semi-sheet/plate things you move on to letting it cool off in argon.

Argon gas, yes.

From here it's so it again with another fold then roll it to very long strips again.

Repeat cooling argon recirculation pump. Pump argon out & compress it into tank. Use compressed argon again, you use vacuum pump for off gassing & volatiles separate, filter them if you can.

Then vacuum pump it, get the strips turned into a nice braid after rolling them thinner & then rolling them sideways long ways to turn them into more fiber while they are still warm. Upon braiding you will roll those all together flat one way then twist that then roll it flat again.

Then from there you need to cool them, so, another cooling stage.

Then vacuum then fold the sheet & roll it & then fold the sheet again & roll it again.

Its done, ish. From here it's needing to be chopped up & it will finally be able to go through extrusion.

Yes. I know. This has been a lot of work... Its worth it though.

From here the chopping up is similar to stripping but all done in the argon cabinet. So it doesn't oxidize, mostly & it remains very cool as argon is a much better thermal conductor than regular air! Yay!

The hot plate you used to squish this would be useful to have in there already. But if not get it. You are going to roll these stupid things into pellets that you can actually use with it, unless you have another method in which case use that. I use a tube roller, it's the rollers but I have a tapered tube on the inside that has grooves in it like a cartoon tunnel drill for villains. Funny, but actually totally usable. I metal 3d printed it using a online website (pcbway, xometry, jlcp, etc etc all work) you don't need it to have grooves I just wanted it to be highly specific in sized & shape at the end.

I also plated it. Nickel (it's stainless steel) plated then nickel boron nitride from Caswell Inc.

You can just get away with a stainless steel funnel you can buy at a store for cooking & it will 100% work! It just needs to have no holes in it. Less argon & a little more heat will do the trick.the pellets come out as little round balls & that's how you know they are done. Personally I recommend no argon in a vacuum so there are no argon pockets of air, but it's okay if they are there in very small quantities & sizes.

If not then you can then vacuum it out & just reheat everything & roll them through again (in the tube) & have it be a slightly smaller size to remove all argon gas pockets & have them come out as little pellets again, woohoo! If you use the plate you just need another plate & you'll rotate the plate around in a circular fashion until you get little pellet balls. Works the same just somewhat more work, you need a separate sheet & or plate for the heated surface below. That's all.

Now from here the sandblaster nozzle & or tungsten carbide rods with a 1.75mm coolant hole will be used. You will need to heat them, typically that means a iron-ceramic (the same in electric stove top coils) heating element & a thermal probe in-between with a little boron nitride thermal paste to tie it all together. This lets you know what you need to know for heat. But! We have to feed pellets into the hole & with need a connector funnel.

Soooo.....

Here's where a lot of things become based on what you want to do & so on. If you have a Dremel (rotary tool) you can use just about any diamond cone shaped but to enlarge one side of the road or sand blaster nozzle. Diamond is harder that tungsten carbide. So it will do it. To fit it a press fit is easiest to do. That means another rod with a 2mm coolant hole is best, but they are massive so you will need to funnel down that other rods (or nozzle) tip that will press fit into that & seal with thermal paste (boron nitride) yes that part is actually necessary. The pressures during extrusion get higher & there is a lot of very small fine particles that will fit through your not perfectly sized holes. Be realistic with yourselves like me & so you will do it good but not perfect...

To feed this in, the pellets, a piston driven heating tube is the only way to do this. Yes, that is right. So an electric motor driving a crank (any piston compressor for ac components will work) is the only way to do this. But you have to rotary tool out the side & 2 stroke it with pellets. You have to drill out, or rotary tool out, the sidewalks near the cylinder (leave 5-10mm of material in-between the cylinder side walls) & place in heating elements (rods that heat up work just fine) but make sure you plate the cylinder side walls with boron nitride to increase the lubricity of the whole thing as well as the piston heads skirts (sides of the puck) with it too. The extrusion has to be at a minimal 35-42 degrees facing downwards to limit oil from the crank getting into the cylinder. I used no oil at all. I just turned it off & let it cool down. I first cleaned the shit out of it with isopropyl alcoholic & degreaser.

I left a thick grease for wheel bearings on the bearing for the crank & piston connection rod. So it would unlikely move into the cylinder.

I do think it will effect the end result of oil gets in. So...I dunno be careful.

Now, I did this all still in the vacuum chamber. Because it was easier than removing everything & I was tired & didn't want to. Soooo... again it might be worth it to just have everything stuff in there & say bah to removing it until it's done.

During the extrusion process the heat for everything is very, EXTREMELY, finely controlled & monitored. The piston is 410c let it warm up everything inside the cylinder, including the plastic, the piston head, & the head that I didn't describe.

Silly me. So the head is modified in a shape that press fits the other rod/nozzle directly into it. Which meant, a hole saw/drill thing & the rotary tool for fine adjustment & sand paper at the end to really make sure. Press fit is a rubber mallet & some cloth because tungsten carbide is extremely hard & can cut through that aluminum like it's not even there. Be careful please. A healthy gasket material on the sides & making sure to fully remove camshaft & making sure the valves remain stuck while also grinding down smooth the valves to be completely as flush as you can to the head is needed, just as much as the inside of the head to taper it to the other rod. The smaller the piston the easier this gets.

Right, back to the temperatures needed. 410c for the piston pump is the best temp to start off with, slow but high torque is best for this.

The next rod/nozzle that is the 2mm coolant hole or sized one is going to be much hotter, 550c the entire way. The heat bleed is crap, so a copper capillary tube is the right call. You just need to drill a hole through the cabinet & seal it with epoxy & run it to a computer radiator & use a computer pump. Works just fine the return line is just a copper tube that goes to the capillary tube at the press fit juncture.

But to make it, likely, much easy on you & I (although I figured quick disconnects with a metal hose clamp would work & so that's the working thing going on moving forward) you could just thermal epoxy & copper tube it up! It works pretty well, as well. You are going to need thermal paste g or epoxy anyways to adhere it to the juncture & transfer heat but still *shrugs* most don't want to solder I get it & this will work from a smaller tube to a larger tube all the same.

From here it's cooling it down only to 485c & keeping that going all the way to where it comes out.

From there a filament holder roll is your best friend. You have to be very careful to not lose heat during the process of rolling it & turning it, so a ir heater works just fine for this. 👍 😁

From here after all pellets are processed & you are fine with the small amount left in the piston pump, you are done. Turn off the ir space heater & let it slowly cool off in the vacuum while you sleep & come back to it after a week because it takes forever for things to cool in a vacuum.

If it's cooled before that, it's okay. But there is a final step to this that has to be done. Anealment. Yeah so in the argon you are going to heat it up to 220c & have it come back down to 15c, roughly, over the course of 3, OMG YES 3 AHHHRRGGGG, days. 3. Days.

After 3 days of waiting & having the temperature slowly cool over that time evenly every 1 hour to make it roughly 15c at the end you are done and your amazingly tough & insanely strong filament is done.

You can print it "normally". The printer needs to have a Tungsten carbide nozzle & that nozzle needs to be boron nitride plated. The heat for extrusion is needed to be around 450c - to 480c.

The plate needs to be 250c but can be just 120c and work but tends to stick a little & sort of sucks.

Higher temps help but I've found not until 250c for my logic sanity checks regarding how this came to be. You'll need to test for your own stuff you, hopefully, make correctly. As per these instructions.

Now from here the 3d printer should be a sealed chamber that you push argon through a small nozzle next to the printer. While it is vacuum pumped out & filtered & cooled before going back in.

Argon is the best way to make this work in a vacuum. You can get away with regular air & standard stuff but it's not really the best way. Sadly. The prints oxidize before the final finish step after printing the piece.

The print should be placed into a little box or something, a bag works, that is also filled with mostly argon (try your best) & then you will heat it up in a oven/kiln.

THIS ISN'T TO REMOVE THE PLASTIC. Its not to get it to that high of a temp. Its to help layer adhesion & to thermal shock it into a freezer.

Or, if you are like me, you heat it up in a oven at 450-550f (broil temp) 232/3c to 287/8c & a pressure cooker filled with dry ice on the bottom is used & then it is sealed after placing the hot print in & slowly venting it out at 5psi until it's fully cooled.

Maintain 5 psi & just let it get to close to dry ice temperature as possible. It doesn't need to be at it, just within 20c. That's it. So calculate thermal mass & time for thermal conductivity for total dry ice to save money. Or, if you are like me, just shove as much as you can in that works & a little more (eyeball methods) & let it cool down making sure to keep venting it. Right, I have a lever on my vent I spent the money for a pressure regulator basically & just needed to drill it out & thread it then screw it on. Works.

I have a thermal proper attached to the print & it's usually inside the thing, if the print allows for it. If not it's best to caution & go for broke for extra cooling time & dry ice. Eyeball method! 😎 Oh yeah!

After that it's let it slowly warm up in the pressure cooker pot & then it's fine-ish to use from them, if you need to immediately.

But, it's best to aneal it with a simple 150c max to room temp over a 8 to 12 (it can be a full day if you just don't want to even look at it until later) hours. I mean this was a lot of work, so eat, drink water, take a shower, do your business, veg out on my content on YouTube, etc etc.

This filament is extreme. Just letting you know. After anealment you can readily use it, but a simple bath of electroless plating of nickel boron nitride for your cylinder, heads, bearings, basically just dunk it in is the easiest way to seal it up & be able to start the honing then cross-hatching process.

Get your bore gauge out & calipers. You need to make sure tolerances are good, everything is squared up, flat, then re-plated.

It will mean a tremendous amount. Don't worry if it doesn't look like it's not 3d printed. You have that where it counts, on the inside 💕 remember 😉.

From here, if you sized it correctly you can use any scooter & or similar single cylinder crank, camshaft, & so on you want.

But you are cool people like me! So! Instead you fully printed all of this, made sure there were holes, dimples, tunnels, & some grooves so you could fully electroform this with nickel & some basic Caswell electroforming/plating with ceramics & metals for infill of those things to increase total strength. Even though the metal, ceramics, & polymers actually should fully ionically bond together after the anealment stage.

Yes that's right, the filament you made ionically bonds metals & ceramics together & does so while also having dendrites & splindles form a network web of inter-weaving lattices that tension to themselves at a molecular & micron/nano scale.

It has to do with the charge values & conductivity during the glass transition phase & plastic phase while the anealment forces excess ions to move out & decay electron orbits into another compounds that needs them. The thermal shock/hardening process set that up to start with but then easing tension off forces a relaxing of the material & moved molecules into a better position for filament dendritic & splindle skin effects to take place. This creates voltage & electromagnetic fields to happen. Which further moves these electrons into a place they need to be using a electron hole & electron redox/ redux (can't remember) flow effect which changes the field effects of the surrounding material due to the electromagnetic z field induced that loops & jumps to other dendrites forming a basic coil. A resonance field effect occurs & changes the properties of the material & it's electrical resistance therein.

This further helps push & pull & bond molecules together to their best state. There are better temperatures & pressures but I know these will work because they are conservative & the effect should occur with them no matter what. But I'm cautious & don't want it to not happen. You can experiment on your own, I'm sure.

To move on, however, this means it's a metamaterial composite that's lighter & stronger than the aluminum & steel you would typically use while being just as thermally conductive as aluminum.

Its even lighter, if done right, than titanium. But that's ratios, leaving areas out that aren't needed, etc etc.

Anyways, that means the crank can be made out of this & made to be plated with a tungsten powder & silicon carbide powder together with a cementing of nickel carbide & boron carbide. The heat shock forces it to bind very well at much lower temperatures than normal.

But you can get away with the tungsten powder, silicon carbide & a little molybdenum & chromium. If you plate like brick & mortar style in the intentional holes & dimples it becomes much stronger & shears into a bind crystalline formation like hardened steel! Cool! Even better is that is doesn't take much by volume, honestly a few grams of each, well ish. If a 75cc engine is assumed then the crank will be needing about 47.865 grams total of everything I talked about with a ratio for the tungsten, silicon carbide, nickel carbide & boron carbide of 7% tungsten 16% silicon carbide 12% nickel carbide 65% boron carbide.

But that's a lot of boron carbide. So. I figured 72% tungsten 8% silicon carbide 11% molybdenum & 9% chromium would be easier because tungsten powder is fairly cheap.

Anyways, nickel forming then boron nitride plating then silicon carbide plating (Caswell kits) then nickel electroforming will work pretty decently well.

Same treatment process for thermal shock & anealment. But it's longer now. The thing has to be thermal shocked & anealed first before electroforming (so it's bonded & strong) but then it has to be done again to make sure it's bond structure goes back & remains strong. Heat & electricity is generated during the electroforming & plating process, which will sever bonds & introduce gaps again. So another round will work to solve that.

After that it's fully done! 👍😁 Completely. You can now make sure tolerances are good, things are bolted together, bearings are there, lube & oil for engine break in is put in, assembly lube used, timing is good, belts are tight, or gears depending on what you do, everything is ready with gaskets (use correct gasket material, like thin aluminum sheet & or steel shim, rtv, etc) & try your best to start her up!

You can print injectors, carbs, heads, valves, crank, camshaft, pumps, compressors, turbos, etc all from this material & it works with extremely high high & tension, pressure & more for even your exhaust. Of course I am talking about after electroforming & plating like I wrote down & you read. It still does without that, but it won't go as far. Its only 20psi max for boost (*sarcastic shrugs* oh well) same for total thickness at play for the cylinder of the engine block. In fill is a big deal & wall thickness too. If you can brick later, do so but remember it's not available for everyone.

Brick layering a 3d print should be a wavy 3d sinusoidal pattern that uses the "wah woo wahhnn woaahh" pattern to have the next layer fit in-between the last. So you do the outside & the inside then fill in the middle to produce the strongest prints. Work with over hangs in the print, if you can, so it will be able to catch correctly. As in the outside wall overhangs into the middle together with the inside, but this time it's such that the middle part for the above layer squeezes out into the outside layers & they can form into that middles overhang. Its like metal inlay. You kind of do a dove tail then press in the metal then sand it down. Well, this is using the heat & the shape of the nozzle to help get it into the area & contract into the overhang & form a 3d mechanical puzzle piece bond with the filament in many areas all over it. Increasing the flex before break (tension) the compression before destruction, & then ability for it to have memory built in, together with a high reduction of occlusions as the heat & filament pushes out the air that could become trapped in-between the print layers.

Boo-yah baby! Oh yeah! *High fives* Alll-rrright! *snaps fingers & finger pistols at you*

This also helps thermal shock hardening to not crack & break the print. But it usually isn't needed, like I said it's not really available to everyone & then on top of it this version above doesn't exist at all you have to program that yourself.

Instead just use a decent in fill & a larger wall thickness that you can electroform later. The crank is similar but should be mostly full in fill.

You are going to have to polish your crank & camshafts. Same with anything else that needs a very smooth surface to work. This is, possibly, the easiest method to delaying your rabbit hole fixation into a hobby that might cost you some money. Its your very own single cylinder 3d printed engine that can handle extreme pressures (the in fill thickness could just be solid to be fair & then it's based on how much filament you made before this) when properly made thick, but then you can liquid cool it & super turbo it with a direct & port injection. Nothing like making a planetary gear set for your camshafts & using a push pull hydraulic ram for your valves to no longer need springs! Together with a gear system for the camshafts that attach to the lobes so you can have a vvt & a type of vvl based upon the gear moving to move the placement of the hydraulic ram it presses on one side then presses up on the exhaust/intake side to allow for a non-payment infringement Lemke transmission valve train setup that gives you your valves as the throttle & it's able to work to high rpm & has not only vvd but vvt as well.

Hey, remember those computer radiators? They still work for this, those electric pumps are still fine for a tiny 75cc hybrid air & liquid cooled engine 😉👍.

Mass production is not easy. So...yup. it can be made to be, but I'll post about it again later.

Please like, comment, & subscribe to my YouTube & my reddit all that. This is the 3d printer recipe for the crazy full 3d printed engine that can actually be fully not electroformed and will work!

Grinding Machines - Essential Tools for Precision and Efficiency

Grinding machines are pivotal in various industrial and manufacturing processes. These machines are designed to achieve high levels of precision by removing material from a workpiece, often for shaping, finishing, or improving surface quality. They play an indispensable role in producing parts with tight tolerances, a key factor for industries such as automotive, aerospace, and toolmaking. Their versatility and precision make them a cornerstone of modern manufacturing.

The Role of Grinding in Manufacturing

Grinding is a machining process that utilizes an abrasive wheel to remove material from a workpiece. Unlike cutting or milling, grinding employs friction to shave off material, making it ideal for achieving fine finishes or precise dimensional tolerances. The grinding process is usually used after other machining operations, such as turning or milling, to refine the surface and remove any imperfections that may have resulted. Whether the task involves sharpening tools, smoothing rough surfaces, or shaping complex geometries, grinding machines are equipped to meet the demands.

Types of Grinding Machines

Grinding machines come in various types, each suited to specific tasks. Surface grinders, one of the most common types, are designed to provide a flat finish on a workpiece. They feature a rotating wheel that moves across the surface of the material, removing thin layers to create a smooth, even surface. Cylindrical grinders are another key type, ideal for working on cylindrical parts. They allow the grinding of both the outer diameter and the inner diameter, which is critical in the production of parts such as shafts, bearings, and pistons.

Centerless grinders are used for high-precision grinding of parts without requiring the need for centers or fixtures. These machines work by holding the workpiece between two rotating wheels—one that drives the part and another that performs the grinding. This type of grinding is highly effective for producing parts in large quantities due to its efficient design. Internal grinding machines are specifically designed for grinding the inner surfaces of workpieces, such as holes, bores, or tubes.

Advancements in Grinding Technology

Over time, grinding technology has evolved to meet the increasing demands for precision, speed, and efficiency. Modern grinding machines incorporate advanced features such as computer numerical control (CNC), which allows for greater automation and precision. CNC grinding machines enable manufacturers to input complex geometries directly into the machine, reducing the likelihood of human error and enhancing repeatability. The use of digital controls also allows for faster setup times, shorter production cycles, and the ability to handle more complex tasks.

Additionally, the development of high-performance grinding wheels and abrasive materials has significantly improved the grinding process. Diamond and cubic boron nitride (CBN) wheels, for instance, offer longer tool life and greater cutting efficiency. These materials are especially effective in grinding harder materials like ceramics, hardened steels, and superalloys used in critical applications such as aerospace and automotive engines.

Applications of Grinding Machines

The applications of grinding machines span a wide range of industries. In the automotive sector, grinding is used for parts like camshafts, crankshafts, gears, and other components requiring tight tolerances. Aerospace companies rely heavily on grinding to produce precision components like turbine blades and engine parts, where surface integrity and dimensional accuracy are crucial for safety and performance.

Grinding machines are also essential in tool and die making. The ability to create intricate features and sharp cutting edges on tools, dies, and molds is made possible through grinding. Moreover, medical device manufacturers use grinding to create components such as orthopedic implants and surgical instruments, where precision and surface finish directly impact functionality and patient safety.

Challenges and Future Trends

Despite their advantages, grinding machines face certain challenges. The high heat generated during the grinding process can cause thermal damage to both the workpiece and the grinding wheel. To address this, modern machines are designed with advanced cooling and lubrication systems to manage heat and reduce wear. Additionally, the use of superabrasives, which are more efficient and durable than traditional abrasives, has helped overcome some of these challenges.

Looking ahead, there is a growing focus on increasing the automation and integration of grinding machines with other manufacturing processes. With the rise of Industry 4.0 and smart manufacturing, grinding machines are becoming more connected and capable of exchanging data in real-time. This allows for predictive maintenance, more efficient production scheduling, and improved process monitoring, ensuring that grinding remains a vital tool in precision manufacturing.

In conclusion, grinding machines are crucial to modern manufacturing due to their ability to achieve high levels of precision and quality.

Realized what to do so my aliens can wear tabards over their (boron nitride, powered) chainmail: “variable ghillie”. In one mode it sticks together as regular cloth, printed with the wearer’s personal device and insignia of rank and rate; in the other mode it comes apart into a bunch of silhouette-disguising strips of terrain-appropriate colors. They’re ambush predators, they never didn’t use camouflage—in previous technological stages, their bright livery was just reversible, and printed with camo on the inside.

Also decided they have optional plates, like mirrors over mail in the Near East, or modern ballistic inserts, made of silicon nitride ceramic—Chinese researchers recently discovered a way to make it as flexible as metal while keeping its ceramic hardness, which I think also means it’s what the aliens make swords out of. And it’s white, in pure form, so it matches the boron nitride. (My humans make blades out of cryogenically worked titanium, which is apparently far less brittle than normal titanium—comparable to steel, but at titanium’s weight. The brand-name for this alloy in my setting is Jottunium, because ice + titan = frost giant.)

Why SBJ Nirmal L Type 14x57 Rotary Hoe/Blade is the Ideal Choice for Farmers

When it comes to preparing soil and ensuring crops have the best start possible, farmers know that quality tools make all the difference. The right rotary Hoe/Blade can mean the difference between smooth soil preparation and days of unnecessary struggle. That’s where SBJ Nirmal L Type 14x57 Rotary Hoe/Blade comes in. With its efficient design and high-quality materials, this blade is made to withstand the challenges of modern farming. Let’s dig deeper into why this blade is so special and what sets it apart in the world of agricultural tools.

What is a Rotary Hoe/Blade, and Why is it Important?

A rotary Hoe/Blade is a critical part of a rotavator, a piece of farming equipment used to break up and aerate the soil. In simple terms, a rotary Hoe/Blade spins into the ground, digging up soil to prepare it for planting. This process helps improve soil structure, aerates it for plant roots, and controls weeds—all vital aspects for healthy crop growth.

The L-shaped design of the SBJ Nirmal 14x57 blade makes it especially effective at penetrating soil. Its unique shape allows the blade to dive deep into the ground with each pass, giving a more thorough till. Whether you’re dealing with compact, rocky, or sandy soil, this blade is built to handle it. Many farmers appreciate this blade because of its ability to handle different soil types without losing efficiency.

Made from Boron Steel: Built to Handle Tough Jobs

One standout feature of SBJ Nirmal L Type 14x57 Rotary Hoe/Blade is the boron steel material it’s crafted from. For those unfamiliar with boron steel, it’s a high-strength steel alloy that includes a small amount of boron. This might seem like a minor addition, but that tiny amount of boron gives the steel incredible strength, hardness, and durability. Farmers benefit from boron steel because it makes the blade tough enough to withstand harsh soil conditions.

Here’s a bit more on boron steel’s advantages:

High Hardness and Strength: Boron gives steel an extra level of hardness and wear resistance. Since farming equipment often takes a lot of punishment, this extra hardness is a huge plus, meaning less wear and fewer replacements.

Resistance to Abrasive Soils: In areas with rocky or gritty soil, blades can wear down fast. Boron steel holds up well against abrasive materials, allowing it to dig deeper and last longer than standard steel.

Great Flexibility: Even though it’s hard and strong, boron steel maintains a level of flexibility. This balance is crucial since overly rigid materials can break under heavy stress, but boron steel can bend without snapping.

With boron steel, SBJ Nirmal blade provides a mix of strength and endurance that most standard blades lack. Farmers who use it report longer life spans for their blades, reducing the need for frequent replacements.

Powder Coating: Protecting the Blade Against Rust and Wear

On top of using durable boron steel, SBJ Nirmal adds a powder coating to its L Type 14x57 Rotary Hoe/Blade. This is a special process where a powder made of resin, pigment, and other particles is applied to the blade’s surface, then heated to form a strong, protective layer. The result is a coating that protects the blade from rust, moisture, and other weather-related damage.

Powder coating is an important feature for a few reasons:

Rust Resistance: As any farmer knows, equipment that stays outdoors is prone to rust. The powder coating provides an extra layer of protection, keeping the blade rust-free and extending its lifespan.

Weatherproofing: From rainy seasons to dry spells, farm equipment faces a range of weather conditions. Powder coating prevents moisture from seeping into the metal, so the blade doesn’t corrode or degrade.

Easy Maintenance: Powder-coated blades are much easier to clean, requiring only a quick rinse to remove dirt or mud. This saves time for busy farmers who want reliable, low-maintenance equipment.

Key Benefits for Farmers Using SBJ Nirmal 14x57 Rotary Hoe/Blade

So, why do farmers trust this particular blade for their rotavators? Here are some of the top reasons this blade has become a popular choice:

Efficient Soil Penetration: The L-type shape is optimized for soil penetration. Its angled edges dig in smoothly, so the blade can handle dense soil without wearing down quickly. This shape also makes it easier to prepare seedbeds with fewer passes, which is a big time-saver.

Versatility Across Soil Types: One major benefit of SBJ Nirmal L Type 14x57 blade is its versatility. Farmers use it successfully on everything from clay-rich soil to sandy ground, as well as rocky areas. This versatility means farmers don’t need different blades for different fields.

Cost-Effective Over Time: Since it’s built to last, this blade is a good investment. The initial cost may be a bit higher than standard blades, but over time, farmers save on replacements and repairs. For those managing large areas or frequent tilling, this long-lasting blade proves especially economical.

Low Maintenance Requirements: With the combination of boron steel and powder coating, this blade is tough and easy to care for. It can handle wet, muddy fields without rusting or degrading, meaning it’s always ready for the next job.
