Maximum efficiency through GROB technology

With the GROB Metal Printing process, GROB-WERKE is setting new standards in the additive manufacturing of mold solutions for particle foam. Aluminum tools produced using GMP technology are not only lighter and more corrosion-resistant than their steel counterparts, but also enable optimum vaporization, venting and homogeneous filling.

This is made possible by the GMP300, a 3D printer that GROB has developed specifically for the fast and cost-effective production of aluminum components. The system processes wire into partially permeable components that are ready for use with minimal further post-processing. It only takes a few days from design to the first foaming process – a decisive advantage for the development of prototypes and series parts with high time and cost pressure. The foaming tools develop their full potential in combination with the BE-AD.MACHINE from Hofmann. Up to 50% porosity in the mold insert ensures optimum vaporization, so that even large components can be produced without any problems. The high number of steam nozzles ensures shorter cycle times thanks to faster heating and cooling processes.

Particularly practical: different mold inserts can easily be used with just one mold frame. This not only saves costs, but also speeds up the production process considerably.

GROB Metal Printing – the next level of additive manufacturing

The GMP process is characterized by high system flexibility, low production costs and a high level of safety. Easy integration into existing production lines means that companies can switch to this innovative technology with little effort.

The second generation of the GMP300 impresses with features such as a further improved sealing concept, real-time monitoring of droplet formation and an optimized shielding gas concept for even higher component quality. A second wire feed system enables faster material changes and additional sensors ensure precise monitoring of the printing process.

Insights into the future of tool manufacturing

Interested companies can experience the power of GMP technology live at the GROB in-house exhibition 2025 from April 1 to 4. With GMP technology, GROB-WERKE is pushing the boundaries of additive manufacturing – faster, more efficiently and more innovatively.
