Three-Dimensional Printing Applications And Materials Used In This Technology
There are a number of three-dimensional printing applications and materials used in this technology. However, all these fabrication materials have to be thoroughly inspected, developed and distributed. The most popular materials used in rapid prototyping technology nowadays are prototyping plastic, wax, resin, polymer, polyurethane, plaster, etc. The process of material choice is not as simple as it seems. There are a lot of factors influencing this choice established by prototyping designers and engineers. So, there are always several factors determining the choice of material and they must be accurately followed. One of such factors is solidity of a future prototyping model and, consequently, its durability. Secondly, there is a wide range of designs and colors that can be chosen by a client or designers in course of model production. Three-dimensional printers can be divided into two groups. The first group includes inject printers, which use mostly such materials as granular substances, including powders and plasters. The second group consists of fused deposition printers. The principle of their work is a bit different comparing to inject printers. The materials used with fused deposition printers are mostly liquid polymers. Such materials as polymers and resin proved to provide the most durable, solid and flexible rapid prototyping models that can be widely used in aggressive environment. However, modern technologies are developing at exponential rates and rapid prototyping, including its various subtypes such as stereo lithography, selective laser sintering, fused deposition modeling and of course three-dimensional printing – is not an exception here, developing more and more new techniques and providing designers with wide range of new prototyping materials.
So, what do we know about three-dimensional printing? The most widespread definition says that it is a computer-aided technology creating a prototyping model by means of layered technology common for all prototyping techniques. This computer-assisted technology is generally called CAD, or computer-aided design. Completion of prototyping models is the main sphere of 3D printing application. Brand new prototyping technologies appearing lately caused the production of new prototyping materials widely used for prototyping and software and hardware providing the accurate production of prototyping models and machines. The main reason why 3D printing is growing popular nowadays is the effectiveness of this manufacturing. Firstly, the cost price of a prototyping model as well as productions costs of 3D models are much lower comparing to the rest of rapid prototyping techniques. Secondly, no other prototyping technique can provide such high speed of prototype production as three-dimensional printing does. Thirdly, 3D model are more accurate than any other prototyping model, which makes it popular among clients. Materials that can be used with 3D printers are of different solidity and color, which makes a perfect choice for customers and designers to fulfill their vision of future product.
