Creavis, the strategic innovation unit of the specialty chemicals company Evonik, has entered into and a research collaboration with Voxeljet AG, a German manufacturer of industrial 3D printing systems to co-develop material systems for the next generation of the binder jetting method in 3D printing.

Binder jetting is a 3D printing technology that uses a binding agent to precisely fuse together particles of a powdered material to form a strong bonded layer and by sequentially carrying out the printing process the complete object is formed.

In this technology, the bonding is carried out at room temperatures which means that common thermal issues like warping, curling and dimensional distortions are not a problem in binder jetting. Currently, this is the most scalable 3D printing technology.

Binder jetting systems are widely used in mould-making but the available material systems for producing industrial final parts are mostly not suitable in terms of their mechanical properties.

Speaking on the collaboration with Voxeljet, Prof. Stefan Buchholz, executive director of Evonik Creavis GmbH said, “Voxeljet is one of the leading manufacturers of large-scale high-speed printers for mould-making. 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.”

Voxeljet is one of the leading manufacturers of binder jetting 3D printing systems and it will use this expertise to collaborate with Evonik’s expertise with polymer powders for various 3D printing technologies and binders fine-tuned to suit the method. Together the companies aim to develop new and innovative material systems.

Excited about partnering with Evonik, Dr. Ingo Ederer, CEO of Voxeljet said, “In Evonik we have found an outstanding collaboration partner that will provide us with tailored material systems for our efficient printing technology. 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.”

Thomas Große-Puppendahl, who runs the innovation growth field at Evonik Additive Manufacturing, said, “Our strategic focus is on the development and manufacture of “ready-to-use” high-performance materials across the major branches of technology. Our close collaboration with our customers and partners is what enables us to forge ahead with innovation.”

The recent collaboration and development of the powder-binder systems are a par tof this innovation growth field.

Evonik will be present at this years’ Formnext event scheduled for November 19 to 22, 2019.
