Evonik and Voxeljet to Develop New Powder-Binder Systems

Specialty chemicals and materials firm Evonik and industrial 3D printing systems manufacturer Voxeljet AG are teaming up to collaborate on the development of new powder-binder systems for the binder-jetting additive manufacturing, Evonik announced in a recent release. The strategic innovation unit of Evonik, Evonik Creavis GmbH, and the Friedberg, Germany-based company will work to develop material systems that have appropriate mechanical properties for the production of industrial final parts. 

“Voxeljet is one of the leading manufacturers of large-scale high-speed printers for mold-making,” Evonik Creavis Executive Director Prof. Stefan Buchholz said in the November 7 release. “We have made it our goal to work with Voxeljet to develop new powder-binder systems that will for the first time enable this method to be used to manufacture polymer parts for industrial use.”

Binder-jetting 3D printing involves the application of powder in layers, which are secured together by a binding agent that is printed on by an inkjet print head based on the specifications of the part. Evonik said binder-jetting is “currently the most productive and most scalable method for 3D printing” because the process occurs at room temperature and large-scale and rapid inkjet technology is more widely available. 

Evonik has existing capabilities in polymer powders for 3D printing and powder-binders. The firm plans to discuss its research on binder-jetting additive manufacturing at the formnext trade show in Frankfurt am Main, Germany running from November 19-22. 

“In Evonik, we have found an outstanding collaboration partner that will provide us with tailored material systems for our efficient printing technology,” Voxeljet Chief Executive Officer Dr. Ingo Ederer said in a statement. “With this research collaboration, we aim to fulfill our aspirations of entering into the safe and robust additive manufacturing of stable polymer final parts in series production.”

In September, Evonik said that it formed a cooperative agreement with additive manufacturing equipment and materials supplier Cubicure to develop new radiation-curing resin systems. The specialty chemicals and materials maker formed a joint development agreement with 3D printing technology firm Evolve Additive Solutions in May to collaborate on the formulation of new thermoplastic materials for use in Evolve’s Selective Thermoplastic Electrophotographic Process (STEP) additive manufacturing systems.
