Eplus3D EP-M400 — Technical data

Eplus3D presented the EP-M400 in April 2023 as a multi-laser system for the step into series production; the technology comes from the large EP-M650 and EP-M1250 models. The build volume measures 400 × 400 × 450 mm including the build plate, and the chamber holds over 70 litres. Depending on equipment, one to four fibre lasers of 500 W work in it, optionally 700 or 1,000 W; the table on the manufacturer page also lists a six-laser variant. Up to 210 cc/h is theoretically possible, and the system weighs around 5.5 t. Since 2024 there has been the more compact EP-M400S, while the EP-M400 remains in the range.

For a used EP-M400 the value depends heavily on the number of lasers, so have the configuration and the power of each source documented. Several lasers mean several scanners that must be calibrated to each other; a test job with specimens across the whole build field shows whether the overlap zones are clean. Also check the filter system, recoater, chamber seal and chiller. For installation, prepare floor loading, a three-phase supply of up to 18 kW and the inert-gas supply.
