Machine tool manufacturer DMG Mori demonstrated at Formnext 2025 in Frankfurt last week how its additive manufacturing (AM) systems – both the LaserTec DED hybrid machines for laser deposition welding and the powder-bed models in the LaserTec SLM series for layer-by-layer manufacture – may be optimised for the series production of metallic components. The company showcased how both technologies can be seamlessly integrated into end-to-end AM process chains.

As part of its MX machining transformation strategy, the manufacturer concentrates on production in one clamping. Accordingly, LaserTec DED machines reduce throughput times by employing a six-in-one process that includes preheating, AM using a powder nozzle, 3D scanning, milling, turning and grinding.

The ability to switch between additive and subtractive technologies allows the creation of complex geometries and multi-material parts that can be endowed with bespoke properties, such as better wear or corrosion protection, or increased resistance to chemicals. AM components often have a long service life and require little maintenance, so their availability is maximised. 

With the latest LaserTec 30 SLM third-generation powder-bed AM machine, DMG Mori has introduced an interchangeable build chamber to eliminate one of the biggest bottlenecks in metal 3D printing, namely long cooling times after completion of the process. The chamber may be removed and replaced with another, pre-prepared chamber without having to wait, so production can continue almost without interruption. 

Set-up times are significantly reduced, as preparation of the chamber is performed away from the machine. This not only eliminates the need for repeated flooding of the chamber with inert gas but also lowers consumption of the shielding gas. An integrated lid increases safety and preserves the protective atmosphere between jobs, allowing powder management and material handling under inert gas conditions.
