High Precision Parts on UnionTech Stereolithography Equipment
Block with interior channels built on UnionTech equipmentStereolithography is one of the most accurate 3D printing technologies. RP America recently built a series of parts for a customer on the UnionTech PILOT 250 stereolithography 3D printer with the goal of demonstrating the extreme accuracy and precise detail the UnionTech equipment is capable of achieving.
The UnionTech PILOT 250 laser can be set for standard beam (0.12 – 0.20 mm) or small beam/high resolution (0.06 – 0.08 mm). For these parts, the operator set the beam for the best possible resolution. Some of the parts had small interior channels, which can be particularly tricky to build given their tendency to close up.
The parts were built with Somos® WaterShed XC 11122, a material known for its clarity and ease of post-processing. Due to the accuracy of the equipment and material properties, after building the operator simply removed the parts from the platform, removed supports, and cleaned the parts. No other post-processing was needed.
