Ditzingen, Germany, September 8, 2023) - TRUMPF, the world's leading provider of machine tools and laser technology solutions, has improved its 3D printing software TruTops Print to print parts with suspension angles as low as 15 degrees with little need for support structures. Trumpf will present its new technology at the European International Machine Tool Show (EMO 2023) in Hannover, Germany.

"The latest version of Trumpf's TruTops Print software virtually eliminates the need for support materials, which means faster build times and lower material consumption." According to Lukas Gebhard, additive manufacturing process development engineer from toolcraft, "Unsupported printing brings parts close to their final shape, opening the door to parts and projects that were not possible before, such as near-net form fabrication of large diameter internal cooling channels."

Previously, users had to print the support structure along with the part to secure the part to the build platform, while also being used to cool the part to prevent internal tension and deformation during printing. Today, Trumpf's innovative technology means that many 3D printing applications can be carried out unsupported, even when working with difficult-to-process materials such as stainless steel.

Software opens new 3D printing strategy

Timo Degen, Product Manager for Additive Manufacturing at TRUMPF, said: "When 3D printing a part, we want to be able to precisely control when and where the material melts and resolidifies. The key is to choose the right exposure strategy to prevent internal tension and overheating in the cantilever area." TruTops Print enables the 3D printer to use the best printing strategy for each different area of the part, eliminating the need for support structures. At the same time, the improved wind field of TrumPF's new 3D printer meets the requirements of uniform processing conditions and unsupported printing.

Unsupported 3D printing technology opens up new applications

Timo Degen, product manager for Additive Manufacturing at TRUMPF, notes that the propping-free printing technology is particularly suitable for challenging situations with large cavities or cantilever components, such as parts such as water tanks, heat exchangers, hydraulic blocks and molds. This new technology also opens up applications that were previously not fully utilized, including additively manufactured radial compressors and shroud impels. In the past, because of the impeller's cantilever Angle, manufacturers were unable to print impellers that did not require support. "The demand for support meant that 3D printing could not economically replace traditional manufacturing, but that has now changed," Degen said.
