Overview
GF Machining Solutions' DMP Factory 500 is the large-format machine of its metal powder-bed range: a cubic build space of 500 x 500 x 500 mm (includes build plate) melted by 3 x 500 W fiber lasers at 1070 nm. It is laid out as a production line of separate units rather than one printer, and the table sizes each of them.
The build process itself is defined by a few rows. The chamber holds a vacuum-based atmosphere at < 25 ppm O₂, a level chosen for titanium and nickel alloys that degrade when they take up oxygen. Layers are adjustable from a minimum of 2 µm to a maximum of 200 µm, with 60 µm as the typical value, which leaves room to trade surface quality against build time on the same job. Powder is spread by a soft blade recoater, which tolerates parts that warp slightly above the powder line better than a rigid blade would.
Listed materials are LaserForm Ni718, Ti Gr23 and AlSi10Mg, with additional alloys on request. Dimensional accuracy is ±0.1–0.2% with ±100 µm minimum, and positional repeatability is 75 µm (3σ) in X, Y and Z; the smallest feature the table allows is 300 μm. On a part that fills the plate, the percentage term will dominate the tolerance band, so datum faces should be left with stock for machining.
The printer module measures 3,010 x 2,350 x 3,160 mm and weighs 8232 kg (excluding RPM). Around it sit a depowdering module of 3,000 x 2,530 x 3,300 mm, a powder recycling module of 1,935 x 2,262 x 2,521 mm, a parking module of 1450 x 1780 x 1850 mm and the 1120 x 850 x 1400 mm removable print module that travels between them. All of this comes from the listed table, which has not been checked against a current product page.

Strengths & Limitations
Strengths
- Cubic 500 x 500 x 500 mm build space including the build plate
- 3 x 500 W fiber lasers at 1070 nm for the large plate
- Vacuum-based chamber atmosphere below 25 ppm O₂ for oxygen-sensitive alloys
- Layer thickness from 2 µm to 200 µm (typical 60 µm) lets one machine run fine and coarse parameter sets
- Removable 1120 x 850 x 1400 mm print module shared with separate depowdering and recycling units
Limitations
- Accuracy of ±0.1–0.2% with ±100 µm minimum means large parts carry a wide tolerance band before machining
- Positional repeatability is 75 µm (3σ), coarser than the 60 µm listed for the DMP Flex 350
- The printer module weighs 8232 kg (excluding RPM) and the depowdering module is 3,300 mm tall
- Three materials are listed (LaserForm Ni718, Ti Gr23, AlSi10Mg); anything else is on request

Frequently Asked Questions
01
The table lists a vacuum-based chamber at < 25 ppm O₂. Keeping oxygen that low protects reactive powders such as Ti Gr23 and nickel alloys like LaserForm Ni718 from pick-up during melting, which affects the mechanical properties of the finished part.
02
Layers are adjustable from a minimum of 2 µm to a maximum of 200 µm, with 60 µm as the typical setting. Thin layers give finer surfaces and detail; thick layers shorten build time on bulky parts. The parameter set has to exist for the chosen material.
03
The DMP Flex 350 builds 275 x 275 x 420 mm and lists 60 µm repeatability and a 200 μm minimum feature. The DMP Factory 500 builds 500 x 500 x 500 mm with 3 x 500 W lasers, a 75 µm repeatability and a 300 μm minimum feature.
04
A printer module (3,010 x 2,350 x 3,160 mm, 8232 kg excluding RPM), a depowdering module (3,000 x 2,530 x 3,300 mm), a powder recycling module (1,935 x 2,262 x 2,521 mm), a parking module (1450 x 1780 x 1850 mm) and the removable print module (1120 x 850 x 1400 mm).
