The GEM demonstrator is made with EnvisionTec SLA additive manufacturing technology using E-RigidForm resin material.

Le démonstrateur GEM est réalisé avec la technologie de fabrication additive SLA EnvisionTec, avec le matériau en résine E-RigidForm.

Polystyrene is a polymer from the styrenics family that offers excellent transparency coupled with a very competitive cost. It has medium mechanical properties making PS rigid and brittle.

Polyvinyl chloride or PVC is a plastic material obtained by polymerization of vinyl chloride monomer. It is an amorphous polymer with very low crystallinity.

The GEM integrates a nano-structuring surface technology that allows the creation of very fine patterns and thus the fight against counterfeiting, either in a discreet and non-reproducible way, or
