Multi Jet Fusion 4200

MJF technology
HP Multi Jet Fusion

Multi Jet Fusion is a new additive manufacturing technology on a powder bed developed by HP.

Erpro Group has three HP machines (Jet Fusion 5200 and 5210) with a plate size of 380x285x380 mm, ideal for the manufacture of functional parts.

Each layer is heated evenly from the start of the process. Then a fusing agent is sprayed onto the surface according to the sections of the pieces and a detailing agent on the contours to improve the resolution of the pieces. When the lamps move over the powder bed, the melting agent captures the heat, creating a layer.

PA 11 bio-based

Erpro Group is the first French company to use biosourced PA 11 on HP multi-jet fusion.
Biosourced PA 11, produced from castor oil, is used in a wide range of applications, due to its properties: chemical resistance, mechanical resistance, ease of implementation, possibility of use in a wide range of temperatures (-40 to + 130 ° C).
