Why Stereolithography?

The SL process as originally commercialized for “industrial” applications and represented in UnionTech stereolithography 3D printers utilizes a build platform that is immersed in a vat of photopolymer creating a layer of polymer formulation ranging from 0.002 in. to 0.010in. A 355 nanometer wavelength laser draws the cross-section of the prescribed layer with instantaneous curing of the photopolymer. The platform then lowers to the desired layer thickness and a recoater passes over the platform to ensure a uniform layer of photopolymer for the next cross-section.

UnionTech equipment is compatible with any photopolymer specifically designed for SL processing. Machine parameters can be adjusted to the degree decided by the equipment owner. Platform sizes vary from 10 square inches to approximately 32 square inches (model dependent), facilitating production of larges parts or multiple smaller parts. These freedoms in design create an open path for innovation and collaboration whether you are considering a prototype, indirect or direct manufacturing option.

New Dimension in
Stereolithography 3D Printing

• Cost effective ownership throughout entire life cycle

• Freedom to collaborate and innovate: open design for materials and machine access

• Surface aesthetics that reset expectations and contribute to lower post finishing requirements
