WESTEC 2017 attendees (re)discover the advantages of stereolithography (SL) processing by hands-on exploration of demo parts and the Pilot SL equipment at the Union Tech Inc. booth.

Union Tech Inc., recently exhibited at WESTEC 2017– the West Coast’s leading manufacturing event. We appreciated the high level of interest from exhibition attendees. Many were encountering the versatility of SL as a 3D printing application for the first time while some notably found cause to revisit their previous perceptions.

On display at the booth was the UnionTechTM Pilot SD, one of two product lines targeted at the commercial market.

Features of the Pilot SD include:

-250 mm x 250 mm x 250 mm platform

-High accuracy and resolution

-Open design for choice of materials

– A market entry price point that expands access to SL capabilities to a larger commercial audience.

In addition to learning about the equipment, many attendees were discovered unfamiliar aspects of the versatility and wide-ranging capabilities of stereolithography (SL) equipment and the latest advances in material through a hands-on exploration of the display parts. These parts demonstrated:

– A wide range of physical and mechanical properties: high clarity, micro-resolution, high-impact combined with stiffness, and temperature resistance greater than 500°F

– Examples demonstrating high accuracy, excellent resolution, and excellent overall aesthetics across a broad range of part size.
