About UnionTech

Rapid prototyping typically refers to a variety of subtractive and additive technologies that translate CAD data to three dimensional objects.Stereolithography has been a widely utilized RP process since the early 1980s.

UnionTech SL equipment provides excellent surface aesthetics.Exceptionally smooth sidewall quality minimizes layer line definition. Textures can be readily applied as part of the model build.

UnionTech SL equipment is compatible with one of the widest ranges of materials available for any AM process including, clear, colorless, pigmented, and ceramic filled materials.

Mission

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.

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.

Rapid Manufacturing is a generic term that can refer to using additive manufacturing to directly produce parts >used in an end-use or indirectly using AM to create patterns and tooling.

Essentially all the processes described under patterns and tooling are applicable to rapidly producing end use parts: SL provides form while the material used in the final process provides properties needed in the final application.
