#extrusion prototyping

[vixencaw]

This is the first entry for my process journal on modeling and printing a 3D figure.

The first thing to note is I have not had any prior experience with 3D modeling or printing before starting this project. My dad, however, has a 3D printer (Ender 3 Pro) that he uses often. He is also somewhat familiar with the 3D modeling program Blender, so that is the program I decided to learn.

Before starting to learn Blender, I drew a simple design of the pose and elements of my figure (image 1). The figure is of a character from a story I am currently writing—he is an angel who wears a cloak and has two sickles as weapons. I had a feeling this would be quite the undertaking for a beginner, but I also didn’t know how quickly I would pick up Blender. If I was going to learn it quickly, I wanted to have enough elements to really challenge myself with.

Once I downloaded Blender, my dad showed me the basics: how to move, scale, and rotate objects; how to add new objects and create meshes; and how to apply modifiers to an object. I also messed around a bit on my own, sculpting a circle to look like a head (image 2). However, I was going to need to learn more in order to create a full figure.

I found this YouTube tutorial by PIXXO 3D which showed me how I could model an entire figure from just a single cube. This video introduced me to mirroring and extrusion, as well as how objects can be altered by selecting and editing a single face. These new techniques allowed me to create first a torso and then limbs and a head by creating new shapes that were attached to preexisting ones. Once I learned how the techniques worked, I used the video as an example but tried to shape the figure on my own (image 3). I did run into some difficulties since the tutorial used an older version of Blender. There were certain ways of morphing an object that didn’t work the way the video showed, and so I had to figure out a different way to achieve the same effect.

After creating a full figure, I then had to pose it. I figured the best way to do so would be to separate the model into pieces that I could rotate and arrange independently of each other (image 4). (You can also see I was messing around with how to create wings—more on that later.) I moved the pieces around, splitting some of them further to achieve the pose that I wanted (image 5). Once the pose was complete, I figured out how to fill in the gaps: by selecting the edges of the gap, I was able to create a new face that joined the pieces together (image 6).

As for the wings, I came up with a technique involving bézier curves. By creating a curve, connecting it in a loop, and then subdividing it with multiple points, I was able to manipulate it into the exact shape I wanted the wing to be. Then I could convert it to a mesh and use grid fill to fill in the shape. I did run into an issue where the fill wasn’t even—there was some weird wrapping going on at the bottom, probably because of how the curve was oriented. But I decided to use it as it was for the moment—I’ll redo the wings later.

I mirrored the wing I’d made and set both of them into the back of the figure (image 7). This was a rough prototype and I wanted to try and print it. I sent my dad the .stl file and he put it into UltiMaker Cura, a program for splicing. Splicing takes a 3D model and figures out what the layers have to be for it to be printed. There were some parts that lacked support because they were hanging in the air (the hands and the wingtips), so my dad showed me how to put supports in that could easily be removed after printing. We scaled the figure to be four inches high and could see the printing would take about three hours.

This was where things got tricky. The first print attempt ended with a big spirally ball of plastic. It seemed the wings were too thin and would need more supports, otherwise the plastic wouldn’t stick to itself and would end up creating a mess. The second print went better, although there were still problems with it—namely, the torso fell out of the body (image 8). The rest of it was in decent shape, but it seems I’ll have to do some work to strengthen the connections. I assume this will involve thickening the objects in Blender so they have more surface area melding them together.

So far, I’ve been able to get the hang of Blender fairly well. This surprised me a bit, although I have had experience with photo-manipulation programs (GIMP) before, so maybe that is helping me more than I thought it would. I am glad the modeling portion is going smoothly, however, since it looks like the printing stage is going to require more finagling than I initially thought.

Rapid Prototyping in Prototype

Rapid prototyping refers to one or several prototypes made first according to the product appearance drawings or structure drawings for checking the appearance or structure reasonableness without opening the mould. With the development of technology, the definition and use of the handpiece has expanded, and it is now more often used to test and validate products, optimize product design, and even used directly as a finished product.

Historical Background and Definition Rapid prototyping technology originated in the 1980s, initially to solve the problems in traditional manufacturing methods, such as high cost and long cycle time. With the development of technology, rapid prototyping has gradually matured and has been widely used in various fields. It is not only suitable for product development, but also has a wide range of applications in software applications, architectural design and other fields.

Process Rapid prototyping processes include a variety of technologies such as Stereolithography (SLA), Fusion Deposition Modeling (FDM) and others. SLA technology initiates the polymerisation of photosensitive resins by means of a light source of a specific wavelength to form polymers, while FDM technology involves the extrusion of melted material in layers. In addition, traditional moulding methods such as vacuum infusion, low pressure casting and CNC machining are also widely used in the production of handmade boards. 1.3D printing: Prototypes are created using a 3D printer by adding material layer by layer. This method allows for fast, low-cost prototyping of products with complex structures. 2.CNC machining: Cutting and engraving of materials by means of computer numerically controlled machines, suitable for prototypes requiring high precision and complex shapes. 3.Vacuum casting: Liquid material is injected into the mould using a mould and then cured into shape, suitable for validation prior to mass production. 4.Rapid tooling: Creation of moulds by means of rapid tooling technology, followed by series production. 5.Injection molding: Mass reproduction using injection moulding machines for situations where mass production is required.

Material There is also a wide selection of materials for rapid prototyping, with common ones such as photosensitive resin and nylon. For small batch production, vacuum casting process can be used, using materials such as ABS and PMMA for replication, followed by subsequent processing such as sanding and spraying with oil. For metal parts, the machining services are mostly used.

Advantages 1.Rapid outputs: Compared to traditional manufacturing methods, rapid prototyping can complete prototyping in a short period of time, greatly reducing product development cycles which suitable for low volume manufacturing. 2.Low cost: 3D printing technology, in particular, allows for the low-cost production of complex structural prototypes and small batches. 3.High flexibility: Can be prototyped using a wide range of materials and techniques, adapting to different design needs. 4.High precision: The ability to accurately replicate the structure, detail and texture of a prototype provides a surface quality. 5.Variety of materials: Polyurethane materials with different properties such as rigid, elastic, transparent or various coloured materials can be selected according to requirements.

Applications 1.Manufacturing and Industrial Applications Rapid prototyping technology enables the rapid production of complex and accurate prototypes, helping designers and engineers to validate design concepts, perform functional testing and evaluate appearance. For parts that need to be produced in small quantities, it offers a cost-effective and flexible solution. 2.Automobile industry Automakers use rapid prototyping technology to rapidly develop prototype automotive parts for performance testing and validation.In addition, it enables the manufacture of personalised automotive parts, such as dashboard panels and door handles, and is used for production tooling. 3.Medical field Rapid prototyping technology enables personalized medical devices, implants and prosthetics to be tailored to a patient's body structure, providing better fit and comfort.In the field of bioprinting, it is used for research in tissue engineering and organ transplantation. 4.Others Rapid prototyping also plays an important role in a number of industries, including aerospace, consumer electronics, and artwork creation, and its applications will become more widespread as technology advances and costs are reduced.

Rapid Prototyping is the process of creating a simple model of a product or project in the early stages of development so that it can be used to validate and test design concepts, features and interfaces. It is a method of rapidly building physical prototypes and iterating on a design with few changes to improve the design.

I'm getting the designs up now

Trump

Wow that's intense so the tank will just be pulling things along and it would be armed to a degree and with a small army and a whole bunch of construction guys this is intense. I thought of it was how he thought of it was what we're doing is two cumbersome takes too long and it's too difficult there's no reason for it you flatten out in front of it somehow you maintain it and you have a very intense Dolly system and that's it really I mean it's nothing complicated so we're going to get to work

Terry c

Tell you what we know how to design the stuff and you need some really good steel now are you really if you want to work it will work and you can cast it and heat it and we're very surprised people didn't think of doing this it says you didn't put too much effort in but now he knows what happens so good

Preston

Yeah and f*** you too idiots and bjA this is perfect for you they have different cities and they're going to compete on how fast they go and they're going to move it too. And Jason probably does his own cities and those kids are using it as a tank and it sucks it's awful and it says I should turn it upside down and that would be better and attach a few together as you can see in the future they tried it seems to work

Bill

Wow that's kind of crazy we've had enough of this s*** no

We are moving out right now

Jason

Wow

Olympus

we help too but wow that's amazing

Apollo and goddess wife

Kind of whipped it up in a few minutes but someone came up with a ramped idea you remembered seeing it to someone and we do see you had these old ones that were like this he couldn't get the extrusion because he doesn't have the mix so he's pulling them out right now not really he might

Duke nukem Blockbuster

Oh yeah that's why they didn't work

Trump

He knows about it but still he's going ahead with it now

Jason

Isn't check anything he's just doing it to bother him and it doesn't bother him cuz he knows what it does

MIT team takes a major step toward fully 3D-printed active electronics

New Post has been published on https://sunalei.org/news/mit-team-takes-a-major-step-toward-fully-3d-printed-active-electronics/

MIT team takes a major step toward fully 3D-printed active electronics

Active electronics — components that can control electrical signals — usually contain semiconductor devices that receive, store, and process information. These components, which must be made in a clean room, require advanced fabrication technology that is not widely available outside a few specialized manufacturing centers.

During the Covid-19 pandemic, the lack of widespread semiconductor fabrication facilities was one cause of a worldwide electronics shortage, which drove up costs for consumers and had implications in everything from economic growth to national defense. The ability to 3D print an entire, active electronic device without the need for semiconductors could bring electronics fabrication to businesses, labs, and homes across the globe.

While this idea is still far off, MIT researchers have taken an important step in that direction by demonstrating fully 3D-printed resettable fuses, which are key components of active electronics that usually require semiconductors.

The researchers’ semiconductor-free devices, which they produced using standard 3D printing hardware and an inexpensive, biodegradable material, can perform the same switching functions as the semiconductor-based transistors used for processing operations in active electronics.

Although still far from achieving the performance of semiconductor transistors, the 3D-printed devices could be used for basic control operations like regulating the speed of an electric motor.

“This technology has real legs. While we cannot compete with silicon as a semiconductor, our idea is not to necessarily replace what is existing, but to push 3D printing technology into uncharted territory. In a nutshell, this is really about democratizing technology. This could allow anyone to create smart hardware far from traditional manufacturing centers,” says Luis Fernando Velásquez-García, a principal research scientist in MIT’s Microsystems Technology Laboratories (MTL) and senior author of a paper describing the devices, which appears in Virtual and Physical Prototyping.

He is joined on the paper by lead author Jorge Cañada, an electrical engineering and computer science graduate student.

An unexpected project

Semiconductors, including silicon, are materials with electrical properties that can be tailored by adding certain impurities. A silicon device can have conductive and insulating regions, depending on how it is engineered. These properties make silicon ideal for producing transistors, which are a basic building block of modern electronics.

However, the researchers didn’t set out to 3D-print semiconductor-free devices that could behave like silicon-based transistors.

This project grew out of another in which they were fabricating magnetic coils using extrusion printing, a process where the printer melts filament and squirts material through a nozzle, fabricating an object layer-by-layer.

They saw an interesting phenomenon in the material they were using, a polymer filament doped with copper nanoparticles.

If they passed a large amount of electric current into the material, it would exhibit a huge spike in resistance but would return to its original level shortly after the current flow stopped.

This property enables engineers to make transistors that can operate as switches, something that is typically only associated with silicon and other semiconductors. Transistors, which switch on and off to process binary data, are used to form logic gates which perform computation.

“We saw that this was something that could help take 3D printing hardware to the next level. It offers a clear way to provide some degree of ‘smart’ to an electronic device,” Velásquez-García says.

The researchers tried to replicate the same phenomenon with other 3D printing filaments, testing polymers doped with carbon, carbon nanotubes, and graphene. In the end, they could not find another printable material that could function as a resettable fuse.

They hypothesize that the copper particles in the material spread out when it is heated by the electric current, which causes a spike in resistance that comes back down when the material cools and the copper particles move closer together. They also think the polymer base of the material changes from crystalline to amorphous when heated, then returns to crystalline when cooled down — a phenomenon known as the polymeric positive temperature coefficient.

“For now, that is our best explanation, but that is not the full answer because that doesn’t explain why it only happened in this combination of materials. We need to do more research, but there is no doubt that this phenomenon is real,” he says.

3D-printing active electronics

The team leveraged the phenomenon to print switches in a single step that could be used to form semiconductor-free logic gates.

The devices are made from thin, 3D-printed traces of the copper-doped polymer. They contain intersecting conductive regions that enable the researchers to regulate the resistance by controlling the voltage fed into the switch.

While the devices did not perform as well as silicon-based transistors, they could be used for simpler control and processing functions, such as turning a motor on and off. Their experiments showed that, even after 4,000 cycles of switching, the devices showed no signs of deterioration.

But there are limits to how small the researchers can make the switches, based on the physics of extrusion printing and the properties of the material. They could print devices that were a few hundred microns, but transistors in state-of-the-art electronics are only few nanometers in diameter.

“The reality is that there are many engineering situations that don’t require the best chips. At the end of the day, all you care about is whether your device can do the task. This technology is able to satisfy a constraint like that,” he says.

However, unlike semiconductor fabrication, their technique uses a biodegradable material and the process uses less energy and produces less waste. The polymer filament could also be doped with other materials, like magnetic microparticles that could enable additional functionalities.

In the future, the researchers want to use this technology to print fully functional electronics. They are striving to fabricate a working magnetic motor using only extrusion 3D printing. They also want to finetune the process so they could build more complex circuits and see how far they can push the performance of these devices.

“This paper demonstrates that active electronic devices can be made using extruded polymeric conductive materials. This technology enables electronics to be built into 3D printed structures. An intriguing application is on-demand 3D printing of mechatronics on board spacecraft,” says Roger Howe, the William E. Ayer Professor of Engineering, Emeritus, at Stanford University, who was not involved with this work.

This work is funded, in part, by Empiriko Corporation.
