SPEE3D is the first additive manufacturing technology based on the coldspray process – Projection of powder at supersonic speed. The SPEE3D machine manufacture parts or preforms of parts, in a quick and inexpensive manner, suitable for productions applications. This technology can for example substitute to the moulding and the vacuum casting processes.
Instead to use the heat to fusion the metallic powder, the patented technology of SPEE3D consist to project the powder thanks to a nozzle which speed up the air up to three time the sound’s speed. The injected powders are deposed on a substrate linked to a 6 axes robot arm. In this process, the pure kinetic energy allow to bond the powders together to create a high density part with normal metallurgical properties.
Theoretically, all the metallic materials can be projected.
The SPEE3D process is actually qualified for:
