Powder Injection Moulding
– Metal Injection Moulding
– Ceramic Injection Moulding
Powder Injection Moulding (PIM) is a technology of fabrication based on mixing ceramic or metallic powder with a polymer system. The feedstock obtained is injected in a mould, getting a part called «green part», which has a elevated content of polymers (around 50 vol.%).
This parts are processed in a furnace where the polymer system is eliminated, obtaining a very porosity part.
After that, sintering stage developed in a furnace allows the part to be full density, obtaining the final parts.
Based on Fused Filament Fabrication (FFF)
Filaments are produced after mixing ceramic or metallic powder with a polymer system.
In an adapted 3D printer for filament, geen parts are obtained with which the process is continued through debinding and sintering stages.
