SOMOS 18420

LIQUID PHOTOPOLYMER

Somos 18420 is a great all around material, it’s opaque white appearance and durability, narrows the gap with engineered plastics.

18420 has good overall properties, which make it ideal for general prototyping, form, fit, concept and presentation.

These SL parts can be sanded, primed, painted, used as pattern masters for urethane casting, or as final show pieces. In an effort to create an “ABS like” material, 18420 has a very good humidity resistence and opaque white appearance.
