TruPrint 1000 Green Edition

Highly reflective materials can be processed thanks to the combination of the TruPrint 1000 with the TRUMPF TruDisk 1020, one of the first industrial green lasers on the market with a wavelength of 515 nm. The TruPrint 1000 Green Edition now makes it possible to 3D print materials such as copper, copper alloys and precious metals which would be impossible or extremely difficult to process with infrared wavelengths.

A variety of applications benefit from the combination of additive manufacturing and the outstanding thermal and electrical properties of pure copper and copper alloys. This opens up new opportunities for manufacturing induction coils or components for complex cooling applications, for example, for power and optoelectronics. By using highly conductive pure copper ETP (EN CW004A) with a specified Cu content of > 99.9 %, the TruPrint 1000 Green Edition is able to achieve an electrical conductivity of 100 % IACS and porosity values of far below 0.5 % for such applications.

The TruPrint 1000 Green Edition even makes it possible to manufacture parts with copper alloys such as CuCr1Zr with a larger process window and higher productivity than infrared LMF laser systems. The TruPrint 1000 Green Edition is also lucrative for applications in the jewellery industry. Density values of > 99.9 % and a pore size smaller than 30 µm can be achieved with materials such as rose gold.
