The one part no one prepared me for when buying a 3D printer was filing wood glue off my skin at one in the morning.

[kaxen]

I used to not like isopropyl alcohol for removing face-ups compared to W&N brush cleaner but it turns out the problem was the drug store stuff was not a high enough percentage.

The 99% isopropyl alcohol I use for cleaning 3D prints is like FACE-UP YEET

And it's cheaper per oz so that's nice.

Types of 3D Printers, Materials, and Applications

What is 3D Printing?

3D Printing or additive manufacturing technologies manufacture three-dimensional parts from computer-aided design (CAD) models by adding material layer by layer until the final physical part is produced. It can be done through a variety of processes where material is deposited, joined, or solidified with the aid of computer control. Materials in the form include plastics, liquids, or powder grains.

3D printing has been around since the 1980’s where it was only suitable for aesthetic protypes considered rapid prototyping but today, especially since 2019, these technologies are considered industrial- production technology, due to the precision, repeatability, and material range.

Today, professional, low-cost desktop and applications of 3D printing aid in creating geometries that were once even impossible by hand and push innovative boundaries in various industries including, jewelry, engineering, dentistry, healthcare, education, and entertainment and more. According to an article published on Statista, “the worldwide market for 3D printing products and services was valued at 12.6 Billion U.S Dollars in 2020 and the industry is expected to grow at a CAGR of 20% between 2020 and 2026.”

How does 3D printing Work?

Every 3D Printer starts with a CAD design file, that is sliced (converted into machine language) and sent to the Printer. Depending on the technology of your printer, the final piece might be produced layer by layer, by solidifying liquid resin or sintering powder. The final parts usually go through post-processing depending on the application.

Design

3D printable models are created with use of CAD software, 3D scanner or other. Models created with CAD software result in the fewest errors. The manual modeling process of preparing geometric data for 3D printing is like plastic arts such as sculpting. CAD models can be saved in stereolithography file format (STL), a de facto CAD file format for additive manufacturing that stores data based on triangulations of the surface of models. Other CAD formats also exist, each with different features and application such as OBJ, 3MF, AMF and more.

Slice

A Slicer software is an important part of the additive manufacturing process. Slicer algorithms convert a 3d printable model into layers that are sent to the 3D printer in machine language called G-code. A G-code file is a series on instructions that machines can understand and move the extruder in ways that prints a model layer by layer. G-code file formats are de-facto for FDM 3D printers, but Resin or SLA, MSLA printers use other formats such as photon file which are images of each layer that a laser cures the resin liquid.

3D Print

Some 3D printers use a roll of filament through a hot extruder to fuse layers into a final piece, others use a laser to cure liquid resin into hardened plastic, others fuse small particles of polymer powder at high temperatures to build parts. Most 3D printers run unattended until the print is complete, and modern systems automatically refill the material required for the parts from cartridges.

Post-Process

Depending on the technology and the material, printed parts may require rinsing in isopropyl alcohol (IPA) to remove any uncured resin from their surface, post-curing to stabilize mechanical properties, manual work to remove support structures, or cleaning with compressed air or a media blaster to remove excess powder.

Types of 3D Printers

The three most common and established 3D printer types for plastic or metal parts are SLA, SLS and FDM. Mintcad supports all these technologies and offers a free slicer software (Jullienne) that allows encrypted 3D printing.

Stereolithography (SLA)

Stereolithography was the first kind of 3D printing technology invented in the 1980’s. and is still one of the most efficient and popular technologies for professionals. SLA 3D printers use lasers to sure liquid resin into a hardened plastic, through the photopolymerizations process.

3D Printing Materials used : Liquid Resin

Fused Deposition Modeling (FDM)

Fused deposition modeling (FDM) is the most widely used type of 3D printing at the consumer level. FDM 3D printers work by extruding thermoplastic filaments, such as ABS (Acrylonitrile Butadiene Styrene), PLA (Polylactic Acid), through a heated nozzle, melting the material and applying the plastic layer by layer to a build platform. Each layer is laid down one at a time until the part is complete.

FDM 3D printers are well-suited for basic proof-of-concept models, as well as quick and low-cost prototyping of simple parts, FDM has the lowest resolution and accuracy when compared to SLA or SLS.

3D Printing Materials used: Plastics (ABS, PLA, PVA, PET), Carbon Fiber, Steel, Silver

Selective Laser Sintering (SLS)

elective laser sintering (SLS) 3D printers use a high-power laser to sinter small particles of polymer powder into a solid structure. The unfused powder supports the part during printing and eliminates the need for dedicated support structures. This makes SLS ideal for complex geometries, including interior features, undercuts, thin walls, and negative features. Parts produced with SLS printing have excellent mechanical characteristics, with strength resembling that of injection-molded parts.

3D Printing Materials used: Metals (Gold, Silver, Platinum, Titanium, Steel and Aluminum), Ceramic.

The Benefits of 3D printing

Speed

With traditional manufacturing methods it can take weeks or months to receive a part or final product of a consumable item. With 3D printing technology this time has been cut out by at least 80%. Some designs can even be printed in just a few hours for prototyping and experimentation to make time to market faster than ever before.

Cost

With 3D printing there is no requirement of expensive setups and machinery required by injection molding or machining. The same equipment can be used for prototyping and even production in some industries. As 3D printing becomes more capable of producing full function end products, it may compliment or even replace traditional manufacturing processes in low or high volumes.              

Customization

From shoes to sports equipment and jewelry, we are surrounded by products made in limited uniform sizes and styles as businesses strive to standardize things to make it more economical to manufacture. With 3D printing and CAD, only the digital design needs to be changed to tailor products for consumer preferences. The concept first took to industries such as medicine and dentistry and has now entered many other industries and is beginning to grow.

New Age Design

3D printing can create complex shapes and parts, such as overhangs, microchannels, and organic shapes, that would be costly or even impossible to produce with traditional manufacturing methods. This provides the opportunity to consolidate assemblies into less individual parts to reduce weight, alleviate weak joints, and cut down on assembly time, unleashing new possibilities for design and engineering.

Applications of 3D printing

3D printing accelerates innovation and supports startups and small businesses in a range of industries, like engineering, jewelry, dentistry, healthcare, education, entertainment, and each have their own use of 3D printer applications.

Engineering

Rapid prototyping through 3D printing technologies empowers designers in engineering to ideate and produce proof of concept and advance these concepts into production. Prototypes that are visual and functional are close to final product ideology and guides designers through a series of validation stages and finalize go to market.

Jewelry

The Jewelry industry uses CAD and 3D Printing to rapidly prototype designs, fill bespoke client needs, and produce large batches of ready to cast pieces. Digital tools allow for the creation of consistent, sharply detailed pieces without the time consuming and low finish hand wax carving.

Education

For immersive learning and advanced research, 3D printers are the go-to multifunctional tools, they encourage creativity and expose students to professional technologies supporting STEM learning and manufacturing.

Healthcare

Affordable, professional-grade desktop 3D printing helps doctors deliver treatments and devices customized healthcare to better serve each unique individual, opening the door to high-impact medical applications while saving organizations significant time and costs from the lab to the operating room.

Entertainment

High-definition physical models are widely used in sculpting, character modeling, and prop making. 3D printed parts have starred in stop-motion films, video games, bespoke costumes, and even special effects for blockbuster movies. Not only that 3D printers can print at home all kinds of toys and board-games for children and adult entertainment.

People will warn you about the smell of resin when 3D printing but I haven’t seen anyone talk about having to deal with isopropyl alcohol which smells objectively Worse

[labtech-chemicals]

What is Isopropyl Alcohol?

Isopropyl Alcohol or IPA is one of the most common solvents in the world. It is often known as rubbing alcohol or IPA. Isopropyl alcohol is most commonly sold in two purity grades - 70 percent and 100 percent.

HINT: ISOPROPYL ALCOHOL IS ALSO KNOWN AS RUBBING ALCOHOL, USUALLY IN ITS 70 PERCENT DILUTION.

What can Isopropyl Alcohol be used for?

HOUSEHOLD USES OF IPA:

Disinfecting surfaces

Making hand sanitiser

Cleaning windows and screens

PROFESSIONAL USES OF IPA:

Sanitises beauty salon tools

Cleans medical equipment

Cleans 3D printing equipment

Does isopropyl alcohol kill bacteria and germs? Isopropyl Alcohol (particularly 60 to 90 percent) is antimicrobial against viruses, fungi and bacteria. It kills microorganisms such as bacteria, germs and fungi or halts their growth, specifically the spread of germs. Isopropyl Alcohol kilss 99.99% of germs in under 30 seconds making it an in-demand and popular sterilisation solution.

What’s the difference between 100% and 70% isopropyl alcohol? The percentage of IPA correlates to the ration of purified water it is diluted with. Pure 100% IPA is not diluted with any water; common formulas include a ratio of 10 - 40% purified water.

Does 70% rubbing alcohol kill germs? Yes. Purified water plays an important role in the effectiveness of Isopropyl Alcohol (IPA) as it delays the evaporation rate and therefore increasing the time it remains effective on a surface. 70 percent IPA solutions are most effective in fully penetrating the cell wall, killing the organism. This slightly diluted formula helps to destroy the harmful properties of common pathogens and microorganisms.

What is 70% isopropyl alcohol used for? 70% IPA is the most commonly used form of this solvent. It is used to sanitise areas where germs may be present including household surfaces, beauty salons and hospitals.

Can 70% Isopropyl Alcohol be used as a Disinfectant? Yes, it is the 70% diluted solution that can act as a disinfectant because the water helps keep the solution on the surface for longer allowing it to penetrate the cell wall of the organism.

What is 99%-100% isopropyl alcohol used for? The highly concentrated version of IPA is much less commonly used than 70% IPA. Most often, 99% IPA is used in industrial application or in scientific research, on products that are sensitive to water.

How do you dilute isopropyl alcohol to 70 percent? Although pure isopropyl alcohol can be diluted, we suggest purchasing a premixed 70% IPA solution. Not only is 70% IPA less expensive, it is also professionally pre-diluted, therefore removing any potential margin of error for mixing.

Where can I buy isopropyl alcohol? Buy from a professional supplier so you know you are getting a pure Isopropyl solution. Here at Labtech we ensure our solutions are high laboratory grade quality so you can be confident it is the best quality available. You are also buying from a reputable Australian supplier - we have been selling Isopropyl Alcohol for over 15 years.

3D modeling and 3D printing workshop 27/2

After a lecture in 3D modelling and a brief on how to work the 3D printers we now have sufficient knowledge for using this tool in our prototypes. 3D printing is very usable for shapes that would be tedious to create out of wood or other means because of a complex shape or more precise tolerances. With this in mind it is also more usable for creating mechanical solutions, as needed parts tend to be simpler to model in CAD rather than cutting out by hand. The safety surrounding the machine is also important, such as be aware of the temperatures of the machine. Further it is also important to remember ways to ensure a successful print, such as not touching the plate after being wiped down with isopropyl alcohol and how to remove the finished product when it has properly cooled down.

SLA Vs. DLP: Which Is The Best Resin 3D Printer Technology?

Let's assume that one of the things you love to do is sculpt figurines. You don't often find passion meeting profit. However, when you have the opportunity to sculpt 100 figurines as part of a large order, you face a problem. You've seen everything about 3D printing . Now you might be curious about the best type of 3D printer to use for your project. You can print with photocuring to get all the details that you need per model.

Resins FDM is the clear winner. Next, we need to decide between SLA 3D Printing services and DLP resin 3D printers. Which is better? The answer is that it all depends on the project. Each has its pros and cons. Let's examine the differences and similarities between them. You should now be able make an informed decision as to which option is right for you.

What is SLA 3D Printing?

Stereolithography (or SLA) is the oldest form 3D printing. It involves using a laser to sweep through a pool of resin and then curing each layer one by one until the build is complete. This method has been used since 1980. These are the basic components of every SLA 3D  printer.

TankThe tank contains the liquid photopolymer, which in normal circumstances is a clear liquid plastic.

Print bedThis is a perforated platform that is immersed in the tank. This platform may move up and down depending on the printer.

Laser:Every layer of resin printed is treated by a powerful ultraviolet laser.

Computer Interface- This controls the movement and position of the light source as well as the print bed. It allows SLA 3D printers, in general, to function without being tied to any computer.

Designs for SLA 3D Printers

The lasers in these printers can either be located below the resin tank, pointing up, or above it, pointing downward. Mirror galvanometers can be used to quickly deflect laser beams from a specific area in the resin. It works like directing sunlight through magnifying glasses and aiming the laser beam at a mirror. The platform is moved away from the light once the laser has printed a layer. This allows the next layer to be cured according to its design.

Pros & Cons Of SLA Printing

Pros

This is the best type of 3D printer.

You can print prototypes with highly detailed features, high-quality, and complex geometrical forms.

It offers dimensional tolerances which are much tighter than most rapid prototyping.

After the build is completed, print surfaces are smooth and do not require any sanding.

You can build a structure as large as 50 cm by 50 cm by 60 cm, without affecting the design's accuracy.

Cons

Printing times can be very long.

Your slopes will get steeper and overhangs may be necessary. Supports must be able to collapse during construction.

Your options and colors for resins are limited.

Many of these resins were created by companies to be compatible with 3D printers.

It is possible to pay high prices for resins as well as maintenance.

What is DLP 3D Printing?

DLP is the same technology used in televisions, projectors, and other devices. The projector screen is used to flash a whole layer on the platform. After it's been translated to 3D, the light source then cures every pixel. DMD (digital micromirror) directs light onto the resin vat to form the layer's pattern.

Pros & Cons Of DLP Printing

Pros

When printing and curing multiple layers at once, it speeds up build time.

The light source is not a laser so it's less expensive to maintain and replace.

Cons

It is difficult to read large print volumes because the pixels/voxels cannot be read on larger scales.

The finish of this build won't look as smooth as SLA builds because the voxels are rectangular.

DLP vs. SLA: What's Difference?

SLA 3D Printing services will offer a range of advantages over DLP printing. The best option for you depends on your specific needs.

Similarities between DLP And SLA

Both SLA 3D Printing and DLP use light to cure a photosensitive resin.

Both methods produce parts that function like injection-molded parts.

They have some significant differences.

There are some differences between DLP & SLA

DLP printers can be found for a fraction of the price, at $400 to $1000. SLA printers come in a more expensive range of $3000 to $4000. The high-end models can go over $10,000, however.

SLA printers can only be used by professionals if there are any problems with the optics or lasers. In these cases, you will need to send the printer back the manufacturer. It's best to make sure that the warranty period is not exceeded. This will prevent any unexpected costs. DLP printers are simpler and easier to manage by their owner.

SLA has a longer post-curing time and a longer build period. For example, a 30-minute build with a DLP printer could take up to four hours.

Additional Important Facts about DLP Vs SLA

Due to the differences in curing and exposure times between SLA printers and DLP ones, resins cannot be interchanged.

Submerge the builds in isopropyl Alcohol to remove any excess resin. Then, cure them in UV ovens. This is similar to a UV lamp in a manicure shop.

DLP printers are believed to be less susceptible to failure because they aren't as complicated as SLA printers.

How does SLA 3D Printing compare to FDM Printing

FDM filaments are layered by layer through hot extruders until they are fully formed. These are some of the properties that filaments can be combined:

Wood

Biological

Metal

Carbon-fiber

FDM's resolution depends on how fast and accurate the motors are moving along with the extruder's diameter to create detailed builds. SLA relies on the tightness of its laser beams.

Post-printingFDM does not require you to take out any supports. You may also need to sand the surface to smooth it.

AdhesionFDM objects can be easily removed. You can also use a palette knife to get rid of any buildup on the print bed. The build can become difficult to remove if there is too much resin on the platform.

CostsFDM nozzles need to be replaced frequently, but they are economical. SLA printers' resin tanks need to be replaced every 2-3 liters because they get smudged. This prevents the light source projecting the resin image clearly. The moving platform should be replaced if it is damaged from SLA removal. It's not cheap, either.

SLA vs. DLP: Which One Should You Choose?

DLP is the better choice if speed and detail are important to you. DLP printers are cheaper than SLA, and they require less outside maintenance.

SLA 3D printing can be a great option if you have the patience. It will give you a beautiful finished surface with many intricate details. It is important to remember that post-print curing can take longer than DLP.

Although both take longer than FDM for these purposes, a DLP Printer is a better choice to quickly get the right parts you need.

My youngest son asked me to make a 3d print of his favorite stuffed animal "Blubbo"...sigh...so I used the opportunity to experiment with slicing my #zbrush sculpt into pieces and creating custom keys for assembly, cleaner prints, and easier airbrushing of colors. Pretty proud of this color I mixed from bright yellow, navy blue, forest green, and white Ceramcoat acrylic paints, and thinned down with distilled water, 90% isopropyl alcohol, and a drop of glycerin for #airbrushing. Swipe for process pics and a #blender render of my 3d model. #digitalsculpting #toymaking #3dprinting #vinyltoys #maker #acryliccraftpaints #blender3d https://www.instagram.com/p/COWE_hTBWeN/?igshid=jsnphqu2cj8w
