TRUMPF, a German provider of machine tools, recently demonstrated the capabilities of its TruPrint 5000 3D printer as well as its newly developed green laser technology.
The TruPrint Laser Metal Fusion (LMF) 3D printer features a 500 °C pre-heater and full-field multi-laser equipment with three 500 Watt fiber lasers, to process materials such as high-carbon steel or titanium alloy components. Additionally, TRUMPF’s green laser is said to have the potential for gold printing in the jewelry industry.
Tool - Mold - Makers - Print - Forming
“Tool and mold makers can now easily print forming tools, punches and dies. Previously, without preheating, that wasn’t possible. This makes it attractive for use in mechanical and plant engineering, as pure copper can be used to print particularly conductive inductors and heat exchangers,” said Tobias Baur, TRUMPF General Manager Additive Manufacturing with responsibility for technology.

Copper and 3D printing
Pure copper is known to have desirable material properties such as malleability, and high thermal and electrical conductivity. However, due to its conductivity, copper has been proven to be a difficult material for additive manufacturing as it reflects the heat applied by a laser beam. Nevertheless, alternative methods have been developed using electron beam melting (EBM) and Optomec’s trademark Aerosol Jet technology to 3D print copper components.
Systems - Laser - Beam - Source - Wavelength
“Conventional systems use an infrared laser as the beam source, but its wavelength is too long and it can’t weld highly reflective materials such as copper and gold. This can be done with laser light in the green wavelength spectrum,” explained Thomas Fehn, TRUMPF General Manager Additive Manufacturing with...
