Frankfurt, 22 November 2025 – UnionTech concluded Formnext 2025 with a strong debut of its RSPro800 X and RA900 industrial SLA systems, unveiled on Day 1 at Hall 11.1 Stand C39. The event saw a surge of interest from visitors, with both new models attracting immediate orders from European partners eager to install them before year-end.
Speed Meets Scale
RSPro800 X – the first four-laser, large-format SLA on the market
The RSPro800 X employs a unique load-balancing algorithm that coordinates four lasers to work simultaneously across different areas, significantly boosting efficiency without compromising precision. This innovation sets a new industry benchmark for speed and accuracy in large-format SLA printing.
– Faster Printing: 4-laser-synchronous printing technology, up to 60% faster than previous system
– High Precision: ±0.1 mm dimensional accuracy and premium surface finish with crisp detail
– Large Format: 800 × 800 × 550 mm build volume, accommodating both large parts and small batch production
– Smart Manufacturing: UT-ONE remote monitoring system supports batch management of multiple devices and data insights
RA900– dual-laser cell optimised for tyre-mould volume production
Engineered specifically for high-precision tyre-mould manufacturing, the RA900 is designed to deliver both efficiency and accuracy.
– Efficient production：Dual-laser configuration with customized build volume (950 × 550 × 400 mm) for tire mold manufacturing, capable of printing 4 tire base molds simultaneously in 36h
– Ultra-fine printing：Surface roughness Ra < 3.5; roundness deviation≤ 0.05 mm; dimensional accuracy ±0.08 mm; point deviation < 95%; specially optimized for complex tire tread patterns
– Stable and reliable：Yield in continuous operation > 95%; long-term operational stability due to a new enclosed optical path system
– Intelligent operation: UT ONE – ‘One for All’ optimized printing processes enable automatic sample placement and support generation, and intelligent production scheduling
Launch-Minute Highlights
At 13:30 on 18 November, Executive Vice President Harry Wang addressed a packed booth audience:
“The RSPro800X and RA900 printers reflect UnionTech’s spirit of Innovation, Precision, and Bold Advancement.Designed for global markets, we’re not just introducing new printers, we’re building a digital manufacturing backbone that redefines what’s possible in industrial 3D printing.
With unmatched speed, accuracy, and reliability, our technology empowers our global customers to achieve more, faster – without compromise.”
After the presentation, attendees crowded the demo area to inspect live builds; by the final day of the show, both demonstration printers had been purchased by European customers, underscoring strong market interest in the new platforms.
UnionTech’s RSPro800 X, with its pioneering four-laser architecture, has set a new industry standard for speed and efficiency in large-format SLA printing.
More than 130 RA-series machines are already installed worldwide for tyre-mould production, “helping one leading tool shop cut average lead time by 80 % and cost by 35 %”. SLA resin patterns for investment casting can be produced in as little as three hours while.
UnionTech’s European sales team adds that every second tyre-mould visitor at Formnext 2025 requested a head-to-head machining comparison—an indication of growing interest in photopolymer alternatives.
