EOS M 400-4 vs DMP Factory 500
Start with the differences that could affect your part. Confirm the complete configuration with each supplier.
The big difference
- DMP Factory 500 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. DMP Factory 500 offers the larger published build space (500 × 500 × 500 mm versus 400 × 400 × 400 mm) — more room for nesting several parts per build or for taller single parts. 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 400-4400 × 400 × 400 mm
DMP Factory 500500 × 500 × 500 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.
