Estimated price range
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 is a metal powder-bed fusion printer with a closed powder loop: the table lists integrated closed-loop sieving, recycling and reloading. Its build volume is 275 x 275 x 420 mm (includes build plate), and it carries one, two or three 500 W fiber lasers at 1070 nm.
In a production cell the powder loop is what changes daily work. Unused powder is sieved and returned to the machine inside the system, so operators spend less time handling powder and the material is not exposed between builds. That fits the vacuum-based atmosphere listed at < 25 ppm O₂, which keeps oxygen pick-up low in reactive metals.
Process rows give a soft blade recoater, adjustable layers from min 5 µm (30, 60 and 90 µm typical), a minimum feature size of 200 μm and a minimum wall thickness of 150 μm. Dimensional accuracy is ±0.1–0.2% with ±100 µm minimum and repeatability 60 µm (3σ). Compatible materials are titanium, aluminum, steel, cobalt-chrome, nickel, copper and refractory alloys. The build-envelope row also lists 350 x 350 x 350 mm, but for the triple-laser machine only.
The Factory version stands 3,470 mm high in printing condition (2,370 x 2,400 x 3,470 mm), against 2,869 mm for the DMP Flex 350; both weigh 4200 kg. These are the listed figures and have not been matched to a current GF page.

Strengths & Limitations
Strengths
- Integrated closed-loop sieving, recycling and reloading of powder
- Vacuum-based atmosphere at < 25 ppm O₂
- One, two or three 500 W fiber lasers at 1070 nm
- Minimum features of 200 μm and walls down to 150 μm
Limitations
- At 3,470 mm it is taller than the DMP Flex 350 (2,869 mm), so check ceiling height
- The 350 x 350 x 350 mm volume is only for the triple-laser machine; others build 275 x 275 x 420 mm
- Accuracy of ±0.1–0.2% with ±100 µm minimum leaves fits and sealing faces for machining

Frequently Asked Questions
01
The table lists integrated closed-loop sieving, recycling and reloading. Powder left after a build is sieved and fed back into the machine within the system, rather than being emptied, sieved and refilled by hand between jobs.
02
Both are listed with the same lasers, build volumes and 4200 kg weight. The Factory version adds the integrated powder loop and stands 3,470 mm high against 2,869 mm. It suits long runs in one material, where the powder loop saves the most handling.
03
Printing takes place in a vacuum-based atmosphere at < 25 ppm O₂. Compatible materials are titanium, aluminum, steel, cobalt-chrome, nickel, copper and refractory alloys.
04
275 x 275 x 420 mm including the build plate. The 350 x 350 x 350 mm envelope in the same row is for the DMP 350 Triple laser machine. The build plate and support structures take part of that height.
