Additive metals, laser sintering, extruded filament, powdered plastics, alloys, photopolymers – the list goes on and on. Today there are a plethora of 3D printing processes and materials to choose from and it’s only growing. The dynamic additive manufacturing market is often difficult to navigate, especially if you’re still learning about the processes. To help you start to filter out certain processes and materials, the application engineers at Stratasys Direct Manufacturing has put together a selection methodology: Application – What is the purpose of the end product? You may need to build a small volume of complex end-use parts which would require strong materials, dimensional accuracy and repeatability. Whereas a sacrificial investment casting pattern is one-time use and needs to burnout clean. Function – What does the part need to do? It may just serve aesthetic purposes in which it just needs to look and feel like an end-use part. Or perhaps you have a hard-working ...
