In the creation of prototypes using this method, polyamide particles are agglomerated using a CO2 laser. The model is made using successive 0.10 mm layers. The material can be loaded with fibreglass (PA GF) or be made of Polypropylene (PP).
Prototypes made using this technology originate from the creation of a silicone mold which is the output of a sterelithography-created master model. The impression of the tooling is then filled with polyurethane resin, using a specific vacuum casting machine.
Innovative technology for rapid prototyping: prototypes are made with a collection of agents deposited on a powder base, after which they are subjected to an increased temperature up to the point of the fusion of the material ; the material will then be ventilated.
