FAQs

3D sand printing technology has been around since the 1990s, yet it is still brimming with possibilities. This process is often referred to as additive manufacturing or additive layering manufacturing. 

3D sand printing uses a computer-generated file to consecutively layer silica sand to form three-dimensional shapes of casting cores and molds. Inspired by the technology of inkjet printers, the sand particles are precisely layered for printing.

The inkjet printer head then sprays the binder liquid in the computerized pattern onto the sand surface to solidify the sand layers into a precision 3D model. The chemical reaction with the pre-catalyzed sand makes it energy-efficient since process heat is not needed. After the cores and mold are solidified, the unused sand can be removed and recycled for future use.
