Eplus3D EP-M550 — Technical data

Name: Eplus3D EP-M550
Brand: Eplus3D

Eplus3D showed the EP-M550 at formnext in November 2025; it transfers the EP-M400S architecture to a larger build field. The build volume measures 550 × 550 × 450 mm and the chamber holds over 136 litres. Four, six or eight fibre lasers of 500 W each, optionally 700 or 1,000 W, work simultaneously; the manufacturer quotes up to 280 cc/h in theory and a deviation of no more than 0.1 mm in the overlap zones. Notable is the footprint of around 4.0 × 1.95 m, small for this class, at about 7 t. Target markets are toolmaking, automotive and aerospace.

As a new product, the EP-M550 will only occasionally be offered used, for example as a demonstration or returned machine. Then the number of lasers, calibration records for all scanner fields, operating hours and remaining warranty count. A connected load of up to 40 kW, cooling for up to eight laser sources and the floor loading must suit the site. Also ask which material packages are released and whether Eplus3D will transfer the machine to the new operator.

2 · Let us search

Nothing suitable? We will search for you – or get an e-mail as soon as a matching machine comes in.

3 · Have parts printed

Not worth your own machine? We produce your parts – request from the LayerByLayer 3D printing service.

Buy or have it printed? For small or changing quantities, having parts printed is often cheaper than your own machine. If you regularly fill many build jobs, your own machine pays off.
