SiCeram GmbH, in cooperation with Spectrum Filaments, has developed an innovative series of ceramic materials for 3D printing using FDM/FFF technology! Four specialized filaments are the first such commercial solution on the global market, enabling 3D printing of high-tech ceramics using typical desktop 3D printers.
3D printing is a new additive forming technology for ceramic components. It will find application mainly for the manufacture of prototypes, small batches or complex geometries, for example with hollow interior spaces, that cannot be produced by other traditional techniques.
Silicon carbide
Silicon carbide is a filament containing high-purity silicon carbide powder. The use of appropriate organic agents as a binder results in a flexible filament that can be used in classic 3D printers operating in FFF / FDM technology. The organic content of the filament amounts to about 21.4 percent by mass.
SSiC is extremely hard and has excellent corrosion resistance over the entire pH range. The resistance at 1,500°C is higher than that at room temperature. The material can be applied in air up to 1,550°C and up to 1,800°C in an inert atmosphere. The thermal conductivity of SSiC is very high, with 120 W/mK compared to stainless steel with 30 W/mK. SSiC is an electrical semiconductor.
The very high hardness of SSiC is accompanied by relatively low fracture toughness. For component design, it could be advantageous to take advantage of the very high compressive strength of 4,000 MPa.
