Technology has evolved to a whole new level with the help of 3D printing. It was not really possible for anyone to actually “print” complicated structures and models using a printer. With the help of a 3D printer, it is amazing how one can bring life to a huge number of host models and prototypes. Undoubtedly, the credit goes to the modern day cutting-edge technology where the printing space has reached an impressive level. At present, there are multiple 3D printing technologies available in the present market, but the most common of them is Fused Deposition Modeling, Selective Laser Sintering, and 3D Polyjet printing to match the needs and requirements of a wide range of clients. In this blog, we are going to bring you a brief comparison of 3D polyjet printing vs. fused deposition modeling.
3D polyjet printing vs. Fused Deposition Modeling
Fused deposition modeling utilizes thermoplastic filament which is melted down and extruded from a print head. Once extruded into the bead, the material is immediately set in high temperature of the machine and then it is layered on a platform. The machine head presents there will repeat the extruding and melting layer by layer until the part is complete. The Polyjet process is a bit different than the fused deposition modeling in a way that the carriage jets photopolymers onto the workspace that are then cured by the UV light. Once a thin layer is created, the process will repeat itself by jetting more layers until the part is fully formed. Since the process and materials are different, the characteristics of different parts vary as well.
The applications of 3D polyjet printing and fused deposition modeling should also be considered. As far as applications go, PolyJet has the ability to create parts with greater intimacy and this is what makes it a good choice for the concept models. 3D PolyJet printing models have made its name in exceptional details; fused deposition modeling has the ability to produce durable parts that are absolutely ready for the end-use applications. If you are looking for fit and function parts, then FDM is the best choice.
The material is another important factor to be considered while comparing 3D printing PolyJet and Fused deposition modeling. It is important to consider the materials required for satisfying the parts required for the application. When it comes to attention to detailing, 3D polyjet printing can produce small features and fine textures that you require. PolyJet can also print different parts that include a variety of flexibilities starting from rubber-like parts that come with a more rigid feel. On the other hand, while printing in FDM, you can also choose from a wide range of thermoplastics that will be able to withstand a variety of elements, right from extreme temperatures to the expose of certain chemicals.
The next factor of comparison is the aesthetics or the surface finish. The importance of how a part is going to look will depend on how the part will be used. For the concept modeling and some prototypes, the surface finish and aesthetics can be very much crucial. If this is the case, then the best option is to use the multiple materials used in 3D polyjet printers. FDM might not provide you with the detailing that polyjet does, but it can still produce parts with complicated geometries.
