Metal casting machine	Watch in brass and wax

Applications

This method is used to manufacture complex prototypes and small series of parts where metal pieces are mandatory for functional testing or for cosmetic application eg. jewellery.

Materials

Common alloys such as aluminum, brass, steel or precious metals can be used.

The process

Depending on the complexity, size and desired quantity, different methods are used.

In investment casting, either Stereolithography Quickcast models, FDM-ABS parts or wax models are embedded in a plaster mould. The original model is cauterized and then finally the metal is cast into the plaster mould.

In sand casting, a precise Stereolithography model serves for the repeated preparation of sand moulds, which are later used to cast the metal parts.
