Overview

The DMP Flex 350 Triple is the three-laser build of the DMP Flex 350 metal powder-bed printer. Three 500 W fiber lasers at 1070 nm work the same plate, and this configuration is the one listed with the 350 x 350 x 350 mm build volume, next to the 275 x 275 x 420 mm (includes build plate) volume of the single- and dual-laser machines.

Choosing between those two volumes is a choice of shape. The 350 mm plate takes more parts per build, or wider single parts, while the 420 mm height of the standard volume suits tall parts. Three lasers share the scanning of each layer, which is what keeps build time in hand when the plate is larger, and is the reason for the third source.

Process conditions are listed as a < 25 ppm O₂ vacuum-based atmosphere with a soft blade recoater. Layers are adjustable from min 5 µm, typically 30, 60 or 90 µm. Dimensional accuracy is ±0.1–0.2% with ±100 µm minimum and positional repeatability 60 µm (3σ) in each axis; minimum feature size is 200 μm and minimum wall thickness 150 μm. Compatible materials are titanium, aluminum, steel, cobalt-chrome, nickel, copper and refractory alloys.

The machine is 2,370 x 2,400 x 2,869 mm and weighs 4200 kg. These are the listed figures and have not been matched to a current GF page.

Strengths & Limitations

Strengths

Three 500 W fiber lasers share the scanning of each layer
350 x 350 x 350 mm build volume, the wider of the two listed envelopes
Vacuum-based atmosphere at < 25 ppm O₂
Minimum wall thickness of 150 μm and minimum feature size of 200 μm
Layer thickness adjustable from min 5 µm

Limitations

The 350 x 350 x 350 mm volume is lower than the 420 mm height of the 275 x 275 x 420 mm envelope
Dimensional accuracy of ±0.1–0.2% with ±100 µm minimum; precision faces need machining
Needs floor space for a 2,370 x 2,400 mm, 4200 kg machine

Best For

Batches of parts nested on a 350 x 350 mm build plate Wide parts that do not fit a 275 x 275 mm plate Titanium, nickel and refractory alloy production

Frequently Asked Questions

01 What does the Triple add to the DMP Flex 350?

A third 500 W fiber laser and, with it, the 350 x 350 x 350 mm build volume. The single and dual versions are listed with 275 x 275 x 420 mm, height inclusive of the build plate.

02 Is the 350 mm build volume always the better choice?

No. It is wider and deeper, which suits nesting more parts on a plate, but its 350 mm height is less than the 420 mm of the standard volume. Tall parts such as long manifolds or brackets may fit only the 275 x 275 x 420 mm configuration.

03 What atmosphere does it print in?

The table lists a vacuum-based atmosphere with < 25 ppm O₂. Low oxygen matters for reactive powders such as titanium and aluminum, where oxygen pick-up affects the properties of the printed part.

04 How fine can the details be?

Minimum feature size is 200 μm and minimum wall thickness 150 μm. Positional repeatability is 60 µm (3σ) on X, Y and Z, and dimensional accuracy ±0.1–0.2% with ±100 µm minimum.
