Overview

The DMG Mori LASERTEC 30 SLM is a laser powder bed fusion machine — selective laser melting — that builds metal parts layer by layer from powder rather than cutting them from stock. It sits in the same product family as the company's subtractive machine tools and shares its control environment with them, which is much of the appeal for a shop adding additive alongside milling and turning rather than treating it as a separate discipline.

Build volume is 325 × 325 × 400 mm (12.8 × 12.8 × 15.7 in), matching the X, Y and Z travels. That is a mid-size chamber: large enough for structural brackets, manifolds, conformally cooled tooling inserts and nested batches of smaller parts, and tall enough at 400 mm that height is rarely the dimension forcing a part redesign. Maximum workpiece weight is 400 kg (881.8 lb), which on a powder bed machine covers the build plate and supports as well as the part.

Laser configuration is where the machine scales. Maximum laser power is 1,000 W, available in single-, dual- or quad-laser form with high-precision optics and full overlap. Full overlap is the detail that matters: any laser can reach any point on the plate, so additional lasers speed up a single large part rather than only helping when several parts are nested apart from each other.

Focus diameter is 80 µm (0.0031 in) and minimum layer thickness 30 µm (0.0012 in). That pairing favours fine features and surface quality over raw build rate — thin layers mean more passes per millimetre of height, so parts justifying this configuration are ones where detail resolution, not throughput, drives the business case.

Recoating is bi-directional with a collision protection system, so the recoater spreads powder in both directions instead of returning empty, and a snagged recoater halts the build instead of ruining it. Powder is handled through the rePLUG exchangeable module with integrated recycling, one material per module. That is what makes running several alloys practical without cross-contamination, but it also means every alloy in production needs its own module — a real cost input when planning a mixed-material portfolio. The machine runs CELOS X with easyAM.

Strengths & Limitations

Strengths

Build volume of 325 x 325 x 400 mm (12.8 x 12.8 x 15.7 in) is tall enough that height rarely forces a part redesign, and wide enough for nested batches of smaller parts
Laser configuration scales from single to dual to quad with full overlap, so any laser can reach any point on the plate - extra lasers speed up a single large part, not only nested ones
Maximum laser power is 1,000 W, through high-precision optics
An 80 µm (0.0031 in) focus diameter with a 30 µm (0.0012 in) minimum layer thickness favours fine features and surface quality
Bi-directional recoating spreads powder in both directions instead of returning empty, and the collision protection system halts a snagged recoater rather than ruining the build
The rePLUG exchangeable powder module with integrated recycling makes running several alloys practical without cross-contamination

Limitations

One material per rePLUG module, so every alloy in production needs its own module - a real cost input when planning a mixed-material portfolio
Thin layers mean more passes per millimetre of height, so the 30 µm minimum layer thickness that gives the resolution also caps build rate
Maximum workpiece weight is 400 kg (881.8 lb), and on a powder bed machine that covers the build plate and supports as well as the part itself
A build volume of 325 x 325 x 400 mm is mid-size; parts beyond it need a larger platform entirely rather than a configuration change
Laser powder bed fusion does not remove post-processing - stress relief, plate removal, support removal and finish machining still follow every build

Best For

Structural brackets, manifolds and parts with internal channels that cannot be machined Conformally cooled tooling inserts for injection moulding Aerospace components in titanium and nickel alloys Medical implants and instruments where fine feature resolution drives the business case Nested batches of smaller parts within a 325 x 325 x 400 mm envelope Shops already running DMG Mori machine tools that want additive inside the same control environment

Frequently Asked Questions

01 How big a part can the LASERTEC 30 SLM build?

Build volume is 325 x 325 x 400 mm (12.8 x 12.8 x 15.7 in), matching the X, Y and Z travels. That covers structural brackets, manifolds, conformally cooled tooling inserts and nested batches of smaller parts, and at 400 mm tall, height is rarely the dimension forcing a redesign. Maximum workpiece weight is 400 kg (881.8 lb), which includes the build plate and supports.

02 What does the multi-laser option actually buy?

Single-, dual- and quad-laser configurations are offered, with high-precision optics and full overlap. Full overlap is the detail that matters: any laser can reach any point on the plate. That means additional lasers accelerate a single large part rather than only helping when several parts are nested apart from each other. Maximum laser power is 1,000 W.

03 What resolution can it hold?

Focus diameter is 80 µm (0.0031 in) and minimum layer thickness 30 µm (0.0012 in). That pairing favours fine features and surface quality over raw build rate, since thin layers mean more passes per millimetre of height. Parts that justify this configuration are ones where detail resolution rather than throughput drives the business case.

04 How does the machine handle multiple materials?

Through the rePLUG exchangeable powder module with integrated powder recycling, one material per module. That is what makes running several alloys practical without cross-contamination. The trade-off is that every alloy in production needs its own module, which becomes a real cost input when planning a mixed-material portfolio.

05 What post-processing does a build still need?

The machine does not shorten the usual additive workflow: stress relief, removal from the build plate, support removal and finish machining of critical surfaces all still follow. DMG Mori's argument is that the LASERTEC shares its CELOS X control environment with the company's subtractive machines, so a shop can keep the whole chain in-house rather than treating additive as a separate discipline.
