DMG Mori LASERTEC 12 SLM

The DMG Mori LASERTEC 12 SLM is the compact entry point in DMG Mori powder bed fusion lineup, built for high-precision metal AM work on small components where detail resolution matters more than build volume. The build envelope measures 125 x 125 x 200 mm (4.9 x 4.9 x 7.9 in), targeting dental prosthetics, jewelry, small medical implants, and precision instrument components.

The machine runs a single 200 W or 400 W fiber laser with a minimum focus diameter of 35 micrometers, which is among the finest spot sizes in production SLM systems. That small focus translates to finer feature resolution, sharper edges, and smoother as-built surfaces compared to systems running 80-100 micrometer spots. Layer thickness options range from 15 to 50 micrometers for ultra-fine resolution work.

DMG Mori builds the LASERTEC 12 on the same cast-and-machined frame philosophy as their CNC machines rather than welded sheet metal. The precision optics module sits on a vibration-isolated platform to maintain beam positioning accuracy during builds. An integrated filter system and inert gas management handle the argon atmosphere with minimal gas consumption.

The rePLUG powder handling module enables contamination-free material changeover, which matters in dental and medical applications where material traceability and cross-contamination prevention are critical. Supported materials include cobalt-chrome (the dental standard), titanium Ti-6Al-4V, stainless steel 316L, and precious metal alloys for jewelry applications.

The CELOS X interface provides build preparation, monitoring, and post-build reporting. The compact footprint of approximately 1.6 x 2.5 meters makes it suitable for dental labs and small production environments. Compared to the larger LASERTEC 30 SLM, the 12 trades build volume for finer resolution and a lower price point. Pricing typically falls in the 00,000 to 00,000 range.
