We use various techniques to make prototypes
The basis is always the 3-D model.
Plastic
From the 3-D model a plastic product is made by applying different layers of plastic to each other.
Sand casting
A sand casting model can also be prepared by using a plastic model. This model is pressed in sand, after which aluminum castings are made in the impression.
Lost wax method
A wax model can be constructed with the 3-D model. This wax model is surrounded with ceramic. As soon as the ceramic has hardened, the wax is melted. After this, aluminum (or another material) can be poured into the ceramic mold.
Milled out solid material
The 3-D model (CAD) can be automatically transformed into machine language (CAM). With this program a model can be milled out of a block of aluminum.
