3D Systems DMP Flex 350 — Technical data

The DMP Flex 350 is the mid-size single-laser system of the DMP range for application development, research and low to medium volume production. A 500 W fibre laser exposes a 275 × 275 × 420 mm build volume; according to the manufacturer the vacuum chamber keeps residual oxygen below 25 ppm, which matters especially for titanium and reactive alloys. The material range extends from titanium, aluminium and nickel alloys to copper, tungsten and niobium. Removable print modules make material changes easier. The machine replaced the ProX DMP 320 and has sister models with two and three lasers.

For a used Flex 350, laser hours, the condition of scanner, protective glass, filter unit and vacuum system, and the service history are decisive. Also important are the approved material parameters, transferability of the 3DXpert licence and any additional print modules. The site needs 400 V/15 kVA, argon and compressed air; at over four tonnes, floor load capacity should also be checked.
