3D Printing Black Photosensitive Resin

The black photosensitive resin material Somos Taurus is the latest high-impact stereolithography (SLA) material series launched by DSM. It has higher mechanical properties and higher heat distortion temperature, which increases the production and use of parts. Parts printed with this 3D printing material are easy to clean and polish, and the performance is basically comparable to that of thermoplastic materials. This large precision part with excellent surface quality and isotropic mechanical properties. Its robustness combined with its charcoal gray appearance makes it ideal for the most demanding functional prototypes and even end-use applications.

Main Benefits Of Black Photosensitive Resin

  • • Excellent strength and durability;
  • • Wide range of applications;
  • •Excellent surface and precision of large parts;
  • • Heat resistance up to 90°C;
  • • Similar to the performance, appearance and feel of thermoplastics;

Ideal Application Of Black Photosensitive Resin

  • • Customized end-use parts;
  • • Robust functional prototype;
  • • Car parts under the hood;
  • • Aerospace function test;
  • • Low-capacity connectors for electronic equipment;

3D Printing Technical Parameters

  • 1. One-time printing size: usually 600x600x400mm;
  • 2. Printing layer thickness: 0.05mm~0.1mm;
  • 3. Achievable accuracy: molding accuracy: ±0.1mm (L≤100mm) or ±0.1%×L (L>100mm)
  • 4. Post-processing: easy polishing, spraying, electroplating, drilling, large size objects can be spliced;
