How much does the DMG Mori LASERTEC 12 SLM cost?
Price estimate
We do not have a price for the DMG Mori LASERTEC 12 SLM that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The DMG MORI LASERTEC 12 SLM is a small-format powder bed machine for selective laser melting, with a build volume of 125 × 125 × 200 mm (4.9 × 4.9 × 7.9 in). Its defining figures are at the fine end: a focus diameter of 35 µm (0.0014 in) and a minimum layer thickness of 20 µm (0.0008 in).
A small spot and thin layers are what resolve thin walls, lattice and honeycomb structures and close-contoured internal cooling channels, the kinds of part DMG MORI names for this machine. The trade-off is build rate. The standard fibre laser is 200 W, with 400 W as an option, and each layer can be as thin as 20 µm (0.0008 in) in a build up to 200 mm (7.9 in) tall. This is a machine for small, detailed parts and functional prototypes made of series materials, not for volume.
Powder is handled in a closed module that DMG MORI calls rePLUG. Each module holds one material and recycles its own powder, so changing alloy means exchanging the module, and the stated time for a contamination-free change between materials is under 2 hours. A duo filter system allows a filter change without interrupting the process, and the powder reservoir is large enough that no manual refilling is needed during a build.
The system is open. All machine settings and process parameters can be adjusted individually, and the choice of powder supplier is not restricted. For users developing their own materials and parameters, an additional powder module, rePLUG RESEARCH, is available as an option.
For larger parts, the LASERTEC 30 SLM has a build volume of 325 × 325 × 400 mm (12.8 × 12.8 × 15.7 in) and 1,000 W of listed laser power.

Strengths & Limitations
Strengths
- Focus diameter of 35 µm (0.0014 in) for fine detail
- Minimum layer thickness of 20 µm (0.0008 in)
- Contamination-free change between materials in under 2 hours by exchanging the rePLUG powder module
- Open system: all machine settings and process parameters adjustable, with unrestricted choice of powder supplier
- Duo filter system permits a filter change without interrupting the build
- Closed powder cycle with integrated powder recycling
Limitations
- Build volume is limited to 125 × 125 × 200 mm (4.9 × 4.9 × 7.9 in)
- Standard laser power is 200 W; the 400 W fibre laser is an option
- Each rePLUG module holds one material, so every additional alloy requires another module
- The rePLUG RESEARCH module for material and parameter development is an option

Frequently Asked Questions
01
The build volume is 125 × 125 × 200 mm (4.9 × 4.9 × 7.9 in) in X, Y and Z. Several different designs can be built side by side in one job, but nothing larger than that envelope fits. The LASERTEC 30 SLM, at 325 × 325 × 400 mm (12.8 × 12.8 × 15.7 in), is the larger machine.
02
A fibre laser, with 200 W as standard and 400 W optional. DMG MORI describes the sources as application-specific. The focus diameter is 35 µm (0.0014 in), and the minimum layer thickness is 20 µm (0.0008 in).
03
DMG MORI states a contamination-free change between different materials in under 2 hours. That works because each rePLUG powder module is dedicated to one material and contains its own closed powder cycle, so the powder circuit is exchanged as a unit when the alloy changes.
04
Yes. DMG MORI describes the LASERTEC 12 SLM as an open system: all machine settings and process parameters can be adjusted individually and the material supplier can be chosen without restriction. The optional rePLUG RESEARCH powder module is intended for material and parameter development on the series machine.
05
No manual refilling is required during the process, according to DMG MORI, because the powder reservoir is large. The duo filter system also allows a filter to be changed without interrupting the process, and powder recycling is integrated in the closed material cycle.
