ExOne Company and Fraunhofer Institute have partnered to develop binder technology suitable for 3D printing reactive materials such as aluminum and titanium.

This follows the companies’ development of the CleanFuse metal binder in 2019. In 1998, ExOne, then part of Extrude Hone, launched what it says is the world’s first commercial metal binder jetting system, the RTS-300.

According to Professor Frank Petzoldt, deputy director of Fraunhofer IFAM, the binder has ‘exceptional’ green part strength and clean burnout at low curing temperature.
