DISCOVER THE MANUFACTURING PROCESS

Your parts are made by stacking layers of CO² laser-melted polymer. This process is used to manufacture extremely complex geometries. In a pre-heated chamber, a powder with a polyamide base (nylon) is deposited on a manufacturing platform.

An infra-red laser beam melts the powder specifically in the areas corresponding to the part. Upon solidifying again, the upper layer fuses to the lower layer, therefore gradually forming the part.

The major advantage of this technology is the fact that manufacturing supports are not required, leaving room for your creativity. Shapes are practically limitless with this process.
