Royal DSM, a science-based company active in health, nutrition and materials, has introduced Somos® Element at Formnext, the international exhibition and conference on additive technologies and tool making in Frankfurt, Germany. This new material in the Somos® additive manufacturing portfolio is used to make complex parts for investment casting applications.
Investment casting is one of the main metal casting techniques used to create industrial end-use parts for the aerospace, energy and automotive industries. Somos® has been involved in investment casting using 3D printed patterns since this technique was first developed.
Somos® Element has been specifically designed to improve the repeatability and quality of 3D printed patterns with its improved dimensional stability and minimal ash content after burnout. Patterns created with Somos® Element burn out efficiently with a minimal amount of ash residue and the residue that is left behind is easily removed, leaving a perfectly clean void in the ceramic shell. Somos® Element is also antimony-free which allows for use in titanium and other super alloy casting applications.
