I heard about this from my supervisor, Dr. Ian Campbell, who recently met with one of Objet’s representatives. Basically the Connex500 machine contains two different materials, one (from what I understand) a rubber-based material, and one a more conventional plastic. This allows printed models to simulate products which would be manufactured by twin-shot moulding processes.

However, designers will be able to do much more than create prototypes of overmoulded parts, because the Connex500 comes with 21 so-called Digital Materials – preset blends of the two materials with specific Shore A (hardness) values. The designer can therefore match (or get close to) the mechanical properties of the manufactured part, which should allow more accurate testing.
