The Materials Of 3D Printing

3D printing is a very fascinating process in the manufacturing world. It isn’t a new manufacturing method, but it seems as if it is, as it is only recently becoming much more available to the people and businesses. In fact, 3D printing is a relatively underground process at the moment; however it is gaining serious momentum. This style of manufacturing has a wide variety of materials to choose from; over 60 in fact. 3D printing allows for the creation of virtually anything with virtually no geometrical limits on each design. Organic creations can come out of this manufacturing method, as well as rigid pieces. I want to cover one method of 3D printing in particular, sometimes referred to as infiltration. This method is used only by a company known as X1 with sand, and zcorp.

In a nutshell, this manufacturing process uses 3D printing to create a weak and porous product, which is then dipped in epoxy, wax, or super glue. Whatever chemical or material that the 3D part is dipped in will then fill into the product like water to a sponge. Based on the final product being so porous, it doesn’t take much for the wax, epoxy, or super glue to fill in, yielding a reasonably hardened product. Let me cover the full process.

Like all 3D printing processes, a computer image will have to be created in some form of CAD software by an engineer or 3D developer. This computer file will then be sent to the advanced computer on the 3D printer. All 3D printing processes are CAM processes, or computer-aided-manufacturing processes. What does this mean? This means that the computer in the printer will tell the jets exactly where to move, and when to do it. When the 3D printer starts up, it will begin by laying down layers of powdered material on to the build envelope, or the “build table” within the printer. Each layer is around 25 microns thick or so. A human hair has a diameter of 20 microns in many cases. Within each layer, the 3D printing process involves laying down an adhesive chemical to hold the material together in accordance to the 3D blueprint designed earlier. The 3d printing process will repeat as each layer is laid down and fused together until a final 3D printed product comes through. The product is pulled from the build envelope I mentioned earlier, where the excess material powder surrounding the product it is recycled. The product will be covered with excess powder, but it can easily be dusted off. The product that leaves the printer is very weak. It will have a lot of air trapped within it; in fact, up to 40% of the product could consist of air. This means that the product is very porous. To fix the product from crumbling very easily, a process known as infiltration is applied to the product. The product is dipped in epoxy, wax, or superglue to gain integrity. Based off of the porous nature of the product, it will essentially suck up the epoxy, wax, or superglue very easily. This results in a final product of a material like sandstone which is somewhat fragile, but very unique.

Hobby Electronics Toys That Turn Kids Into Engineers

There is one technology that is rising in popularity across the world; it has been around for a couple decades, but is just now becoming available to consumers and designers. This technology gives artists the chance to manufacture virtually anything, out of so many materials. This newer style of manufacturing is known as rapid prototyping, or 3D printing. What’s 3D printing? 3D printing is additive manufacturing, rapid prototyping, or just another form of manufacturing that brings in a new style of creation. 3D Printing uses 3D printers, or manufacturing machines, which lay down layers of material on top of layers, all while fusing together these materials. Essentially, 3D printing consists of the layer by layer assembly of objects within 3D printers. The designs and blueprints which are used to create these models come from 3D models created by artists and developers across the world! This gives 3D enthusiasts and engineers the chance to create a variety of products.

3D printing is different from other forms of manufacturing like mold manufacturing, or CNC cutting. Through the layer by layer concept, 3D printing can manufacture virtually anything out of a wide variety of materials. Artists can manufacture virtually anything! This layer by layer concept can be easier in quite a few aspects when it comes down to actually designing models, and it doesn’t give certain limitations that other forms of manufacturing give off.

3D printing can give consumers and artists across the globe to manufacture virtually anything. Depending on the material, pricing can be pretty inexpensive as well. In addition, artists don’t have to order in bulk as they might have to when dealing with manufacturers. It wouldn’t be ridiculous to order a quantity of 4-5, or even 1-2. This makes it easier for custom pieces to be created.

On top of the efficiency of 3D printing, this technology offers such a variety of materials to choose from when developing a product or model. There are quite a few 3D printing companies across the globe offering loads of materials, some even offer over 50! Image that, over 50 materials to choose from. Artists and engineers have the option to create their model or gizmo in virtually any material, whether it be cobalt chrome, to sandstone, to colored prints, to abs, to precious metals, and on and on! There are so many options! This gives artists and engineers so many options when it comes down to 3d printing. There are metals, ceramics, plastics, thermoplastics, precious metals, mechanical materials, flexible materials, see through materials, high detail materials, etc. There is a lot to choose from when it comes down to 3D printing! Perhaps an engineer is looking for a very specialized piece that can withstand massive heat, or a piece that is chemically resistant and waterproof. Maybe an artist is just looking for a detailed material so that he or she can show off a design. There is an opportunity for virtually any model!

The availability of 3D printing services is growing across the globe. There are companies everywhere! Some services are offered world-wide as well. The possibility of 3D printing is becoming very widespread, anyone can do it!
