How much does the 3D Systems DMP Flex 350 Dual cost?
Estimated price range
Our best estimate for a metal additive manufacturing in this class — not a quote from 3D Systems. Configuration moves it a long way.
Overview
The 3D Systems DMP Flex 350 Dual puts two 500W fiber lasers over a 275 x 275 x 420 mm build volume. The envelope is the same one the DMP Flex 350 has, so the reason to pick the Dual is hours per build and not part size.
How much time the second laser saves depends on the job. Two beams share the exposure of each layer, which helps most on full plates and on parts with heavy cross-sections. Recoating between layers takes as long as it would with a single beam, so a build made of many thin layers and little exposed area gains less. Before buying on throughput, have a representative plate quoted as a build time.
Both lasers work at 1070 nm. The process rows are a 5 μm minimum layer thickness with 30, 60 and 90 μm as typical values, a 200 μm minimum feature size, typical accuracy of ± 0.1-0.2% with a ± 100 μm minimum, and repeatability of Δx, Δy and Δz (3σ) = 60um. A part that spans the area where the two lasers meet depends on how well they are aligned to each other. No alignment figure is given, so ask 3D Systems how it is calibrated.
The remaining rows cover a soft blade recoater and build platform heating of 250°C.

Strengths & Limitations
Strengths
- 2 x 500W fiber lasers share the exposure of every layer
- Same 275 x 275 x 420 mm build volume as the DMP Flex 350, so parts and plates carry over
- Layer thickness adjustable from a 5 μm minimum, with 30, 60 and 90 μm typical
- Build platform heating of 250°C
Limitations
- The second laser adds output, not size: the envelope stays at 275 x 275 x 420 mm
- No figure is given for the alignment between the two lasers
- Minimum feature size is 200 μm and typical accuracy has a ± 100 μm minimum

Frequently Asked Questions
01
A second laser. The DMP Flex 350 Dual is listed with 2 x 500W fiber lasers, and it keeps the 275 x 275 x 420 mm build volume of the DMP Flex 350. The gain is in exposure time per layer, so it shows most on full plates and thick sections.
02
Not on every job. Two 500W lasers can halve the exposure time of a layer at best, but spreading powder between layers takes the same time as before. Builds with many layers and little exposed area gain least. 3D Systems gives no build-rate figure in the table, so ask for a time estimate on your own parts.
03
Minimum feature size is 200 μm. Typical accuracy is ± 0.1-0.2% with a ± 100 μm minimum, and repeatability is Δx, Δy and Δz (3σ) = 60um. Layer thickness is adjustable from 5 μm, with 30, 60 and 90 μm as the typical values.
