EOS M 300-4 vs DMG MORI LASERTEC 30 SLM 3rd Gen
Start with the differences that could affect your part. Confirm the complete configuration with each supplier.
The big difference
- DMG MORI LASERTEC 30 SLM 3rd Gen has the larger published build-space volume.
- Both use Powder bed fusion · laser powder bed fusion (LPBF).
- These specifications alone cannot tell us which machine will make a given part faster or cheaper.
What this pairing comes down to
Both are Powder bed fusion · laser powder bed fusion (LPBF) platforms, so the practical comparison comes down to scale and productivity configuration. Published build volumes are closely matched, so envelope size is unlikely to decide this pairing. The spec sheet narrows the field; your volumes and quotes decide the buy case — the calculator computes the crossing for this pair.

Published build-space comparison
EOS M 300-4300 × 300 × 435 mm
DMG MORI LASERTEC 30 SLM 3rd Gen325 × 325 × 400 mm
Proportional X and Z dimensions. Depth is listed in the numbers. Nominal envelopes are not usable part space; see configuration and platform caveats below.
Build size is the maximum published physical space. Energy or laser counts describe the machine configuration; they do not prove a throughput winner.
What do these differences actually mean?
A difference may matter when your part size, material, production plan or process qualification requires it. Confirm the exact application with both suppliers; this page does not declare a winner.
What public specs cannot tell you
Real throughputYour geometry, orientation, parameters and finishing route matter.
Actual yieldPublished specs do not tell you your accepted-part rejection rate.
Total installed priceInstallation, training, service, software and options require a current quote.
Finished-part costPrinting is only one part of the complete accepted-part route.
Service qualityLocal response, parts availability and support experience need supplier validation.
Qualified application fitPublic specs cannot approve your material, parameters, tolerances or inspection plan.
