Let's talk about Silicon Nitride! This #ceramic material has a high toughness level, being stronger than Alumina. It also has good resistance to thermal shocks, wear, and corrosion (liquids and gas) among other properties. These properties allow silicon nitride to be an excellent material for application in semiconductors, pump and valves components, and heating tubes.
Traditional Silicon Nitride is very difficult to machine, given its high hardness and toughness. Due to this, only simple shapes can be produced. With #3Dprintingtechnology, the production of ceramics has been revolutionised. Complex shapes that were once impossible to achieve have been made possible!
Creatz3D Ceramics exhibited a few of their Silicon Nitride Ceramics creations Formnext - Where ideas take shape.

The heat exchanger is an example of application to the industry, showing off the highly detailed silicon nitride ceramic component with a large number of channels. 3D printing gives us the freedom of design by allowing us to create curved fins that will greatly increase the surface area for heat dissipation, generating a superior heat exchanger that cannot be done by traditional methods.
