Published build-space comparison

DMP Flex 350275 × 275 × 420 mm
Nikon SLM 280 2.0280 × 280 × 365 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.
