Intro to Ceramic 3D Printing - 3D Printing
2020-1-24 · The modern 3D printing space is a far cry from the days of plastic prototypes. Today’s users have their choice of materials, from rigid and flexible polymers to high-performance composites. One such material that’s finding more uses across industries is ceramic. We touched lightly on ceramic 3D printing when we looked at metal DLP 3D […]
How can very hard parts be deburred? | Engineer Live
2020-6-3 · The product utilised to prove the concept was a 6 inch diameter tool with silicon carbide filaments. Because the burrs were a bit heavier and the customer was not concerned about the final surface finish, the machine shop opted for 80 grit. The tool can be automated on CNC equipment or offline as a secondary deburring operation.
Horizon 2020: a look at the EU’s flagship rail projects
The project resulted in a handful of new technologies, including smaller, lighter, more efficient and reliable traction systems using incipient silicon carbide semiconductor technology, a wireless TCMS, and three new noise separation methods tested in real conditions – advanced transfer path analysis, beamforming and wave signature extraction.

Self-healing materials and the automotive industry
2 · A notable example is self-healing ceramics, where the ceramic can repair due to the reaction between oxygen molecules, which enter a crack, and silicon carbide in the ceramic. This reaction forms silicon dioxide, which reacts with another ceramic component, alumina, to form a material that fills the gap and crystallises into a hardened form.
