At this year’s Formnext Expo, UnionTech (Hall 11.1, booth C39) centered its presence around two new resin 3D printers, a broader portfolio of in-house resins, and a 1.5-meter demonstration part meant to signal growing demand for large-format polymer production.

All3DP was on hand for the company’s launched event of the RSPro800 X, which it describes as the first SLA system to use a four-laser architecture in a large-format machine. According to UnionTech, the model is designed to improve efficiency by up to 60% while retaining high precision.

A second launch, the RA900, targets tire-mold manufacturing—an application where UnionTech reports increasing adoption—with the new system capable of producing four moulds in a single run.

Beyond hardware, UnionTech, which makes resin 3D printers in SLA, LCD, and DLP, is showing off its line of self-developed resins, including high-temperature, tough, and transparent grades. A “material bar” at the stand displays more than ten formulations for industrial use.

Attracting onlookers at the booth was a 1.5-meter, one-piece automotive dashboard (pictured above, right), produced on the RSPro2100, the company’s 2100 × 700 × 800 mm build-volume machine. UnionTech says the part is representative of trends in automotive R&D, where single-shot builds are increasingly used to shorten iteration cycles. Other displays compare tyre-mould lead times—traditionally measured in weeks—to the multi-day workflows UnionTech says are possible with its SLA, and will outline similar time and cost reductions in investment-casting pattern production.
