Our best estimate for a metal additive manufacturing in this class — not a quote from GF Machining Solutions. Configuration moves it a long way.
Overview
The DMP Factory 350 Dual is the two-laser build of the DMP Factory 350 metal printer: two 500 W fiber lasers at 1070 nm scan one 275 x 275 x 420 mm build volume (includes build plate). The second laser is about throughput. Two sources split the scanning of each layer, so a well-filled plate finishes sooner than on the single-laser machine, while the envelope stays the same.
The 350 x 350 x 350 mm envelope that appears in the same table belongs to the triple-laser machine, not to this one. A buyer who needs a wider plate rather than a faster one is looking at the Triple.
As a Factory model it has integrated closed-loop sieving, recycling and reloading of powder and a vacuum-based atmosphere at < 25 ppm O₂. Powder goes down with a soft blade recoater in layers adjustable from min 5 µm, typically 30, 60 and 90 µm. Listed detail limits are a 200 μm minimum feature and a 150 μm minimum wall; dimensional accuracy is ±0.1–0.2% with ±100 µm minimum and repeatability 60 µm (3σ) on each axis.
Two lasers on one layer raise a point to check: where their fields overlap, the stitching between them should be shown on a sample part in the alloy you plan to use. Compatible materials are titanium, aluminum, steel, cobalt-chrome, nickel, copper and refractory alloys. The machine is 2,370 x 2,400 x 3,470 mm and 4200 kg; these are the listed figures, not matched to a current GF page.

Strengths & Limitations
Strengths
- Two 500 W fiber lasers share each layer for shorter builds on full plates
- Integrated closed-loop powder sieving, recycling and reloading
- Vacuum-based atmosphere at < 25 ppm O₂ for reactive alloys
- Keeps the full 420 mm build height of the 275 x 275 x 420 mm envelope
Limitations
- Build volume stays 275 x 275 x 420 mm; the 350 x 350 x 350 mm volume needs the triple-laser machine
- Stitching where the two laser fields overlap should be checked on sample parts
- 3,470 mm tall and 4200 kg, so ceiling height and floor loading need checking

Frequently Asked Questions
01
Both 500 W fiber lasers scan the same layer, each covering part of the plate, so a full plate takes less time than with one laser. It does not enlarge the build volume, which stays 275 x 275 x 420 mm including the build plate.
02
No. The table's build-envelope row gives 350 x 350 x 350 mm for the DMP 350 Triple laser only. The Dual and single-laser machines build within 275 x 275 x 420 mm.
03
The table lists closed-loop sieving, recycling and reloading. Powder is sieved and returned inside the system between builds, which cuts manual powder handling and keeps the material away from air.
04
Compatible materials are titanium, aluminum, steel, cobalt-chrome, nickel, copper and refractory alloys. Minimum feature size is 200 μm, minimum wall thickness 150 μm, and layer thickness is adjustable from min 5 µm.
