In the Sand Additive Casting® process, a negative mould for a part is laser printed in a bed of sand. This sand mould is later used in the foundry to cast the metal part and perishes during the casting process, allowing engineers and designers to make changes to the part at any time, as there is no permanent tool.
This process is very environmentally friendly as sand is a readily available resource that can be re-used and easily be re-introduced into the eco-system at the end of its use.
