Starbond CoS Powder 30

Non-Precious Metal Powder for Dental Prostheses Production with Metal 3D Printing

Starbond Easy dental alloy powder can be utilized to produce dentures via a laser melting process with exceptional mechanical properties. Users can benefit from favourable processing qualities and the alloy's components, which offer maximum flexibility in selecting ceramics and guarantee superb veneering results.

The Star of Metal 3D Printing. Manufacture with Starbond CoS Powder 30 Non-Precious Metal

Starbond CoS Powder 30 by Scheftner is a selective laser melting (SLM) or laser powder bed fusion (LPBF) metal 3D printing material designed to produce high-quality dental prostheses. It is a derivative of the original dental bonding alloy Starbond CoS from S&S Scheftner. Its manufacturing process ensures the best possible flowability. 

  • No cooling phase is required, depending on the ceramics
  • Excellent veneering
  • A CTE of 14.4 permits great flexibility in the ceramic selection
  • Biocompatible with an excellent corrosion resistance
  • CE-certified
