The TruPrint 5000 3D printer from Trumpf processes considerably more materials than conventional systems. It can even be used to produce objects made of copper or precious metals such as gold or silver. The manufacturer sees applications in tool and mold making, medical technology and the jewelry industry.
Unlike most other additive manufacturing systems, the machine operates with a preheater for the base material. The material is heated to temperatures up to 500°C. This allows the TruPrint 5000 to create components made of steel with a high carbon content or titanium alloys without tearing or warping. "Tool and die makers can use it to print forming tools, punches or dies. Without preheating, this was not possible," says Tobias Baur, head of Trumpf Additive Manufacturing.
The company is also using a new green laser with pulse function to process for the first time pure copper and precious metals in a 3D printer. This makes the use of this production technology in mechanical and plant engineering attractive, because particularly conductive inductors or heat exchangers can easily be printed from pure copper. The green laser also has great potential for printing gold for the jewellery industry. Individual single pieces can be produced on demand and expensive material can be saved at the same time.
