Somos® PerFORM


Somos® PerFORM

Somos® PerFORM makes it possible to create models that are extremely rigid and resistant to high temperatures. Somos® PerFORM is the ideal material for tool making and for applications useful for wind tunnel testing.
The material is ideal for many high performance engineering applications such as aerospace orautomotive.

  • Excellent surface yield;
  • Excellent yield of finishing processes;
  • Resistance to hig temperature.

With the lowest viscosity among stereolithography materials Somos® PerFORM allows rapid production times, ease of post-processing and superior surface quality in order to guarantee a very high definition of details.
