Complex parts can make prototyping or end-use production a bit more challenging. They cannot simply be made manually, especially if you require them for low to mid-volume production as that could result in inconsistencies with the quality of the finished product. Moreover, some processes like rapid tooling and CNC machining may not be able to accommodate the complex designs. In that case, you can turn to fused deposition modeling or FDM, a 3D printing technology that is versatile and capable of building parts from a range of high-quality materials. How FDM 3D printing builds parts With fused deposition modeling, you take an extruding plastic filament to be fed through a nozzle in the FDM 3D printer before it is laid on a build chamber layer per layer. This way, the process is able to realize complex geometries. That said, there are restrictions on the process, particularly with overhanging features. In that case, support material will be placed to keep those features in place, and it will be removed at post-processing. Build parts from robust materials Because of the wide range of materials available, fused deposition modeling or FDM is ideal for low volume production and building quick prototypes. Reputable service providers offer a wide range of materials from common production materials like PC and ABC to performance plastics like nylon and Ultem. This way, the process is more versatile for building functional bits, enclosures, and housings. Be sure to work with the right company When it comes to fused deposition modeling or FDM, it makes sense to work only with the right service provider with a team that can support your project. Since FDM crafts components one layer at a time from a filament, the material’s diameter will determine what can and cannot be printed. You need to make sure that the minimum wall thickness is as thick as the material, and if there are holes in your design, it must be bigger than intended for 3D printing, as FDM tends to make them two to four percent smaller. Reputable service providers will review your project for free and help you with your design.
