Ceramic Beads for ExOne, Voxeljet, KOCEL 3D Sand Printing

Short Description:

Description: ceramic beads for ExOne, Voxeljet, KOCEL 3D sand printing

Ceramic beads, which is popular called ceramic sand in China, Japanese often called Cerabeads, are a type of premium ceramic foundry sand used to create sand molds and cores for metal casting high-value products in the foundry business. It is a extremely stable artificial ball sand with mullite crystals.

As the sand 3D printing raw material, now the it have been successful using in ExOne, Voxeljet, KOCEL, etc. printers.
