Overview

The DMP Flex 350 is the flexible-use version of GF's 350-class metal powder-bed printers. Its defining feature is a removable print module for rapid material changeover. For a shop running several alloys, that is what keeps a change of material from turning into a full clean-down of the machine.

It prints with one, two or three 500 W fiber lasers at 1070 nm. Build envelope is 275 x 275 x 420 mm (height inclusive of build plate), or 350 x 350 x 350 mm. Powder is spread by a soft blade recoater, which copes with slight part distortion better than a rigid blade would. Layer thickness is adjustable from min. 5 μm, with 30, 60 and 90 μm typical.

Detail limits are listed as a minimum feature size of 200 μm and a minimum wall thickness of 150 μm, with accuracy of ± 0.1-0.2% with ± 100 μm minimum and repeatability of 60 μm (3σ) on each axis. The material list covers aluminum, titanium, stainless and maraging steel, cobalt-chrome, nickel alloys, tungsten, niobium (C-103) and copper alloys, and build preparation runs in 3DXpert.

In printing condition the DMP Flex 350 is 2370 x 2400 x 2869 mm, lower than the 3470 mm of the DMP Factory 350, and both are listed at 4200 kg. These are the listed figures; they have not been matched to a current GF page.

Strengths & Limitations

Strengths

Removable print module for rapid material changeover between alloys
Lower machine than the DMP Factory 350: 2869 mm against 3470 mm in printing condition
Soft blade recoater with layers from min. 5 μm
Minimum feature size of 200 μm and minimum wall thickness of 150 μm
Material list includes tungsten, niobium (C-103) and copper alloys

Limitations

The table lists no powder-handling system, so sieving and powder transfer must be planned separately or confirmed with GF
The 350 x 350 x 350 mm volume needs the three-laser build; otherwise the envelope is 275 x 275 x 420 mm
Accuracy of ± 0.1-0.2% with ± 100 μm minimum leaves functional faces for machining

Best For

Shops printing several alloys and changing material often Prototype and development work across a wide material list Parts within 275 x 275 x 420 mm with walls down to 150 μm

Frequently Asked Questions

01 What is the removable print module on the DMP Flex 350 for?

The table describes it as a removable print module for rapid material changeover. For a shop that switches between, for example, titanium and nickel alloys, it shortens the downtime of a material change compared with cleaning out the whole build chamber.

02 How does the DMP Flex 350 differ from the DMP Factory 350?

In printing condition the DMP Flex 350 is 2370 x 2400 x 2869 mm and the DMP Factory 350 is 2370 x 2400 x 3470 mm. The Flex is the version with the removable print module; the Factory version carries integrated sieving and powder conveyance. Lasers, build volumes and the 4200 kg weight are listed the same.

03 What are the detail limits?

Minimum feature size is 200 μm and minimum wall thickness 150 μm. Layer thickness is adjustable from min. 5 μm, typically 30, 60 or 90 μm; thinner layers resolve finer detail at the expense of a longer build.

04 Which materials can it print?

Aluminum, titanium, stainless steel, maraging steel, cobalt-chrome, nickel alloys, tungsten, niobium (C-103) and copper alloys are listed. Parameter sets and powder supply for a given alloy grade should be confirmed before ordering.
