Today, industrial-grade stereolithography equipment, at both a commercial and production scale, offers product developers and manufacturers one of the largest installed equipment bases and a range of application capabilities.
UnionTech (St. Charles, IL), a division of Shanghai Union Technology Corp., has been developing and manufacturing stereolithography 3D-printing equipment for nearly 20 years in an environment of intense regional competition. At formnext 2017 in Frankfurt, Germany, on Nov. 14 to 17, UnionTech will allow visitors to explore a range of applications made possible by integrating the printing capabilities of stereolithography with an open design philosophy of equipment, materials and software. The company is exhibiting in hall 3.1 on stand C14.
For example, injection molding tooling benefits from the ability to use a third-generation, filled composite material, Somos PerFORM from DSM, featuring elevated temperature performance greater than 250° C for maximized tool performance. Layers as thin as 0.05 mm are possible with exceptionally smooth sidewalls to reduce secondary finishing.
Metal clad composites utilize established structural nickel plating processes to achieve mechanical properties approaching die cast aluminum or magnesium. Alternate plating strategies create composites with tailored wear surfaces and EMI/RFI shielding characteristics.
The range of available UnionTech platform sizes, from 250 x 250 to 800 x 80 mm, coupled with full density parts with excellent aesthetics opens a wide range of application possibilities including housings, wave guides and mechanical components. The appropriate plating strategy offers a bridge between the performance capability gap of the strongest additive manufactured polymer parts and direct metal.
