Eventually yr’s TCT Asia, UnionTech highlighted the corporate’s use circumstances within the automotive trade and its distinctive tyre moulding functions. One yr on, on the 2025 occasion, the corporate has launched a brand new machine particularly geared toward that utility: the RA900 stereolithography (SLA) 3D printer. The announcement was made on the Shanghai Nationwide Exhibition and Conference Centre (March 17-19), the place UnionTech, a veteran of the Chinese language additive manufacturing sector for 25 years, additionally showcased its broader industrial options, together with metallic 3D printing techniques and new supplies.
The RA900 boasts a considerable construct quantity of 950 x 550 x 400 mm. UnionTech states that is ample for the simultaneous printing of 4 medium-sized tyre moulds, a key promoting level for quantity manufacturing. A major function of the brand new machine is its dual-laser system. This reportedly eliminates the necessity to sew collectively a number of prints, a typical requirement with smaller construct areas. UnionTech suggests it will result in enhancements in manufacturing line effectivity and assist producers meet tighter deadlines.
UnionTech is selling a number of efficiency enhancements with the RA900. The corporate claims that an optimised management algorithm, working along side a wonderful laser spot dimension, ends in sharper mould options and smoother “R” angles (nook radii). They state a key dimensional accuracy of ±0.1mm and a floor roughness (Ra) of lower than 3.5. Moreover, UnionTech claims the RA900 can obtain a metal sheet thickness management accuracy of 0.03mm.
Past accuracy, UnionTech can also be highlighting the RA900’s pace. They report that the machine gives greater than double the manufacturing pace in comparison with a typical 600-format 3D printer. A single medium-sized mould can doubtlessly be produced in as little as 10 hours, a major discount from the 19.6 hours UnionTech attributes to “abnormal gear.” The corporate additionally cites a steady working components yield fee exceeding 95%.
To enhance workflow, the RA900 is designed to combine with UnionTech’s “UT ONE” software program. This integration is meant to streamline the method from preliminary design to ultimate print, with options like computerized pattern format, clever manufacturing scheduling, and one-click print plan technology, all geared toward minimising the necessity for guide intervention. The RA900 additionally incorporates UnionTech’s “third-generation micron-level closed-loop liquid degree management know-how,” which reportedly retains liquid degree top variations under 0.01mm. Automated laser energy calibration and fast spot mode diagnostics are additionally included to boost general course of stability.
Past the RA900, UnionTech offered its industrial metallic 3D printers, the Muees430 and Fuees430. These machines each provide a construct quantity of 430 x 340 x 400 mm and use a number of lasers. The Muees430 is focused at basic industrial functions, together with metallic shoe moulds, prototypes, and aerospace parts. The Fuees430, in distinction, is particularly designed for the footwear trade, specializing in fast metallic shoe mould manufacturing. Each techniques are stated to have scan speeds of as much as 6 m/s and soar speeds of 18 m/s, with the corporate claiming a full-format spot uniformity of 92% for the Muees430.
For the dental sector, UnionTech showcased the D300, a completely automated DLP 3D printer meant for big and medium-sized dental laboratories. The D300 is designed for producing restoration and implant fashions and automates your complete 3D printing course of, together with computerized plate splitting and queuing, computerized resin replenishment, printing, and even help with post-processing.
UnionTech additionally launched new SLA supplies on the present. These included TUF 127, described as a troublesome, heat-resistant materials with a reported warmth deflection temperature of 82°C, and Temp-R220, a high-temperature materials with a claimed warmth deflection temperature exceeding 220°C and a long-term use temperature above 250°C.
Throughout the occasion, UnionTech introduced a major milestone: a worldwide put in base of over 10,000 SLA techniques. The corporate representatives emphasised the continued convergence of 3D printing and AI, suggesting additional potential for innovation throughout the trade.
