EOS M 290 vs DMP Flex 350
Start with the differences that could affect your part. Confirm the complete configuration with each supplier.
The big difference
- DMP Flex 350 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 Flex 350 offers the larger published build space (275 × 275 × 420 mm versus 250 × 250 × 325 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
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.
