Black photosensitive resin Somos Taurus is the latest in DSM DSM’s range of high impact stereolithography (SLA) materials, with high mechanical properties and high thermal deformation temperature, increasing the production and use of parts.Parts printed with this 3D-printed material are easy to clean and polish, and the performance is basically comparable to thermoplastic materials.This is a large, accurate part with excellent surface quality and isotropic mechanical properties.Its robustness combined with a charcoal grey appearance makes it ideal for the most demanding functional prototypes and even end-use applications.
The main benefits of black photosensitive resin are:
• Excellent strength and durability;
• wide range of applications;
• Excellent surface and large part accuracy;
• Heat resistance up to 90°C;
• Performance, appearance and feel similar to thermoplastics;
Black photosensitive resin ideal application:
• Customized end-use parts;
• Solid functional prototypes;
• Car parts under the hood;
• Aerospace functional testing;
• Low capacity connectors for electronic equipment;
Technical parameters of 3D printing
1, a molding printing size: usually 600x600x400mm;
2, printing layer thickness: 0.05mm~0.1mm;
3, the accuracy can be achieved: molding accuracy: ±0.1mm (L≤100mm) or ±0.1%×L (L > 100mm)
4, post-processing: easy polishing, spraying, electroplating, drilling, can join large size objects;
