WE HAVE THE RIGHT Polymer POWDERs FOR the MJF Technology powered by HP Inc.
Multi Jet Fusion™
Evonik is driving forward its commitment to the attractive 3D printing market: The specialty chemicals company participates in HP Inc.’s Open Platform program and introduce new customized powder materials to the market for HP Multi Jet Fusion™ technology.
New polyamides for advanced sintering processes
Polyamide 12 is the material of choice for a new process from the US IT group HP Inc. that is marketed by HP’s Open Platform Program. Evonik and HP Inc. are intensifying their cooperation in the development of new plastic powders for 3D printing. As the first materials manufacturer, the specialty chemicals company placed a certified product VESTOSINT® 3D Z2773 on HPs "Open Platform Program".
The new PA 12 powder convinces with superior mechanical properties and is FDA compliant, as the components printed on the basis of VESTOSINT® can be approved by the Food and Drug Administration for food contact. So, the use of additive manufacturing technologies in food production equipment components which require flexibility due to limited quantities or unique, complex designs is conceivable.
The Multi Jet Fusion™ technology works similarly to the more familiar ink jet printing. On an ultrathin powder layer, a large number of nozzles apply two different agents: The fusing agent sketches out very accurately the desired shape of the component, while a second agent determines the physical outline of the layer being created. The entire surface is then heated by an infrared lamp. Only the fusing agent absorbs the heat and transmits it to the powder particles. These fuse into the prescribed structure while the surrounding material remains unaffected.
The advantages are twofold: The process works about ten times as fast as other additive processes, and the indirect fusion protects the polymer chains so that the defined properties of the material are retained. Evonik participates participate in HP’s Open Platform Program and provide additional powder materials for Multi Jet Fusion™ technology.
