Greetings. We have been using Dupont's Somos resins in all of our SLA machines
with great results. The heat resistance for the Somos material has been a
benefit to many of our customers as well as the other properties the resin

By thermally treating the SLA parts (post processing) we achieve the following

SLA250 Somos 7110 ~87 degrees C

SLA350 Somos 7120 ~85 degress C

SLA500 Somos 7100 ~102 degress C
