Watershed™ 11120 Stereolithography Resin

PERIDOT uses Watershed 11120 stereolithography resin to create semi-transparent rapid prototypes.Description

WaterShed™ 11120 is a durable, strong, semi-transparent, water-resistant resin for use in Solid State (355 nm) Laser stereolithography systems. This low viscosity liquid photopolymer produces strong, tough, water-resistant parts. Parts created with WaterShed™ 11120 have a light green tinge, similar in color to plate glass.

Application

WaterShed™ 11120 offers many properties that mimic traditional engineering plastics including ABS and PBT. This makes the material ideal for many applications in the automotive, medical and consumer electronics markets and include:

  • Water flow analysis
  • RTV patterns
  • Durable concept models
  • Wind tunnel testing
  • Quickcast patterns
