Union Tech Inc. and RP Sales America Get Enthusiasm

Stereolithography (SL), the first 3D-printing technology, has seen continued innovation in equipment, materials, and application know-how in recent years and has one of the largest globally installed bases of all additive manufacturing technologies. However, SL technology, in its current state of advanced development, has often taken a backseat to news generated by the wide array of emerging AM technologies.

At the recent Rapid & TCT 2017 expo, Union Tech Inc., and their US distributor, RP Sales America, encouraged exhibit attendees to explore SL by examining the UnionTech™ line of SL equipment and parts built on those machines. They also offered activities featuring the benefits of SL as a tool that expands and even transcends rapid prototyping solutions.

Everyone who stopped by the booth was impressed with the capabilities of today’s stereolithography technology and UnionTechTM’s equipment that exceed many ingrained perceptions of SL as a prototyping-only solution. Many attendees were enthusiastic about incorporating the demonstrated advances in material that dramatically increase toughness and temperature capabilities and application possibilities, such as metal-clad composites and lightweighted structures, into future projects as a means to further growth. Aspects of the UnionTechTM RSPro SL product line that also impressed attendees were the freedom of material choice and the overall cost-effectiveness of the product line.

Most agreed that interacting with 3D parts at large and small scales gave them an eye-opening perspective of the potential of VR and additive manufacturing. RP Sales America plans to add additional VR experiences, including training on the UnionTechTM equipment. Check back for updates at:

Photo Caption: This footstool (18”x10”x10”), keeping with RAPID’s Pittsburgh-inspired bridge theme, was produced on UnionTechTM’s intermediate-sized machine, the RSPro 600. It caught attendees’ attention as they walked the aisle. Once participants touched the extremely smooth surfaces and complex features, made possible by SL, they quickly moved over to explore the UnionTechTM machine on display.
