Patterns and Tooling

While stereolithography is most often associated with prototyping, patterns and tooling account for a substantially higher percentage of overall SL material usage.

UnionTech SL equipment is available in a range of sizes that can accommodate most master pattern needs. Photopolymers from multiple suppliers are well established for master pattern use and can be used on UnionTech SL equipment without restriction.

UnionTech SL equipment utilizes a special software to create hollow, reinforced patterns that can withstand the ceramic pattern production process and still be efficiently removed via incineration without damaging the shell.

The exceptionally smooth sidewalls produced by UnionTech SL coupled with the improved ease of finishing available from current filled composite SL formulations further enable this type of application for prototype, functional testing and bridge tooling.
