Somos 9120 for SLA 3D Printing
Somos 9120 is translucent in appearance and is our most flexible stereolithography material available.
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.
