What is Somos 9120 Material?
Somos 9120 is translucent in appearance. It’s also the most flexible stereolithography material available with a flexural modulus of 1,600 MPa. Its mechanical properties are similar to the average values of injection-molded polypropylene except for a
slightly lower elongation at break.
Applications
PP-Like Translucent is often used for medical device prototypes, electrical casings, fluid flow analysis parts, and automotive components.
Tolerances
For well-designed parts, tolerances in the X/Y dimension of ±0.002 in. (0.05mm) for the first inch plus ±0.001 in./in.,
and Z-dimension tolerances of ±0.005 in. (0.127mm) for the first inch plus ±0.001 in./in. (0.001mm/mm), can typically be achieved.
Note that tolerances may change depending on part geometry.
