Glass and ceramic 3D printers have always been complex machines, recently AIM3D has launched its newest generation of multimaterial printheads for its composite extrusion modeling (CEM), capable of printing Plastic, metal and ceramics. CEM combines the metal injection molding process (MIM), a well-known method, with the process technologies from additive manufacturing.
The result is a very simple process that is based on cost-effective and easily available injection molding pellets and offers the freedom of 3D printing. The CEM process not only reduces material costs significantly, but also machine costs. Already known problems in production, such as residual stresses, are significantly reduced in the CEM process.
CEM-E2 extruder. Capable of printing metal, plastic, and ceramics, the extruder’s print heads are optimized for different materials and are designed to achieve improved accuracy, higher surface quality, and better mechanical properties of parts. AIM3D has also developed its own ceramic Pellets, in combination with the CEM extruder this makes possible for the making of 3D printed ceramic parts.
The process of how this pellets become a final 3D printed part are described bellow:
3D printing Ceramic is not an easy task. Most of the existing methods rely on high temperature to help reach the ceramics melting point to later mold it into the desired form, but laying particles of it in the desired form to later fuse them together is a much more efficient and controlled method.
