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 Flex 350 is a metal powder-bed fusion printer listed at 2,370 x 2,400 x 2,869 mm and 4200 kg, with a 275 x 275 x 420 mm build volume (includes build plate) and one, two or three 500 W fiber lasers at 1070 nm. At 2,869 mm it is the lower of the two 350-class frames: the DMP Factory 350 stands 3470 mm in printing condition.

What the shorter frame leaves out is not stated in this table, which has no powder-management row. The Factory pages list integrated closed-loop sieving, recycling and reloading; for the Flex, ask how powder is sieved and returned, because that decides how much handling operators do between builds.

The printing process itself is listed the same: a vacuum-based atmosphere at < 25 ppm O₂, a soft blade recoater and layers adjustable from min 5 µm, with 30, 60 and 90 µm typical. Thin layers give finer surfaces on down-skins and small features; thick layers cut build time on bulky parts. Minimum feature size is 200 μm and minimum wall thickness 150 μm.

Dimensional accuracy is ±0.1–0.2% with ±100 µm minimum and positional repeatability 60 µm (3σ) on X, Y and Z, so bores and mating faces will still go to a machining step. Compatible materials are titanium, aluminum, steel, cobalt-chrome, nickel, copper and refractory alloys. These are the listed figures and have not been matched to a current GF page.

Strengths & Limitations

Strengths

Lower frame than the DMP Factory 350: 2,869 mm against 3470 mm in printing condition
One, two or three 500 W fiber lasers at 1070 nm
Vacuum-based atmosphere at < 25 ppm O₂
Soft blade recoater with layers from min 5 µm

Limitations

The table lists no integrated powder sieving or reloading, unlike the DMP Factory 350
Build volume of 275 x 275 x 420 mm unless the triple-laser 350 x 350 x 350 mm build is chosen
A 200 μm minimum feature and accuracy of ±0.1–0.2% with ±100 µm minimum; fine fits need machining

Best For

Metal AM where ceiling height rules out a taller machine Development work in titanium, nickel and copper alloys Parts up to 420 mm tall within a 275 x 275 mm plate

Frequently Asked Questions

01 How tall is the DMP Flex 350?

In printing condition it is 2,370 x 2,400 x 2,869 mm, against 2370 x 2400 x 3470 mm for the DMP Factory 350 on the same 2,370 x 2,400 mm footprint. Both are listed at 4200 kg.

02 Does the DMP Flex 350 have automatic powder handling?

Its table has no powder-management row. The DMP Factory 350 lists integrated closed-loop sieving, recycling and reloading. Ask how powder recovery works on the Flex before planning operator time.

03 What build volume is available?

275 x 275 x 420 mm including the build plate with one or two lasers. The same row lists 350 x 350 x 350 mm for the DMP 350 Triple laser machine.

04 What process conditions does it print in?

A vacuum-based atmosphere at < 25 ppm O₂ with a soft blade recoater. Layers are adjustable from min 5 µm, typically 30, 60 or 90 µm, and the minimum wall thickness is 150 μm.
