Top French engineering schools École polytechnique and ENSTA ParisTech invest in BeAM technology

Prestigious French engineering schools École Polytechnique and ENSTA ParisTech have invested in one of BeAM’s Laser Metal Deposition (LMD) additive manufacturing machines.

The 3D printer, which is based on metal powder deposition technology, is to be installed at the École Polytechnique and ENSTA ParisTech’s additive manufacturing centre.

Additive Manufacturing refers to new manufacturing processes in which objects are built by layering materials. This offers a genuine opportunity for innovation, enabling the design of innovative materials and original prototypes that were hitherto inconceivable using standard manufacturing processes. With a view to entering this new field of research, École Polytechnique and ENSTA ParisTech have acquired a metal additive manufacturing (3D printing) machine to add to their existing range of equipment, which is designed more for polymers and plastics. This investment was largely subsidised by French Defence Procurement Agency, the DGA. 

Cutting-edge technology to drive innovation

Metal powders are injected into the machine’s nozzle to create a homogenous stream. These are subsequently melted by a laser beam to obtain a dense, homogenous metal layer whose metallurgical properties stand between those of cast and forged metal parts. A neutral gas protects the deposited substance from oxidization. The printer then applies layer-upon-layer of this metallic substance to create new parts or repair/add functionalities to existing components by following instructions in a digital file. This system has been shown to enable the repair and innovative design of critical components, such as those used inside turbine engines.
