Robocasting is a freeform fabrication technique for dense ceramics and composites that is based on layer-wise deposition of highly loaded colloidalslurries. The process is essentially binderless with less than 1% organics and parts can be fabricated, dried, and completely sintered in less than 24 hours. This overview w...

Electron beam melting (EBM) is one of the powder-bed fusion additive manufacturing technologies. This technology is very suitable for producing near-net-shape small to medium volume metallic parts with complex geometries. However, layer-by-layer fusion step introduces rapid thermal cycles, which results in a different ...
