TRUMPF Makes 3D-printing More Productive with Two 700-Watt Lasers

TRUMPF has equipped the TruPrint 3000 with an integrated cooling system for the build platform and increased the laser power of the two fiber lasers to 700 Watts. "The TruPrint 3000 is designed for volume production of high-quality parts. Users from all industries, such as the automotive and aerospace industries, will benefit from it," says Roland Spiegelhalder, Product Manager for Additive Manufacturing at TRUMPF. The high-tech company is presenting the 3D printer at Formnext, the leading trade show for additive manufacturing, in Frankfurt, Germany.

In the TruPrint 3000, a system monitors the process area and maintains a constant temperature. This allows the 3D printer to use the full 700 watts of laser power without overheating the material during the printing process. This is especially important for aluminum alloys, for example. The integrated cooling also allows the material to cool more quickly. As a result, components are more durable and there is a high level of reproducibility, meaning that the machine can print the same part repeatedly with the same quality standard. This benefits industries such as automotive, where the TruPrint 3000 can be used to mass-produce crash-resistant parts.  

Thanks to the increased laser power of 700 watts, TRUMPF was able to increase the size of the machine's two laser spots from 80 to 200 µm using special optics. This allows the lasers to process a larger area on the build plate. "This increases the productivity of the system while maintaining the same high part quality," says Spiegelhalder.
