EOS M 400-4 buyer page for four-laser production metal AM searches. Validate laser count, build volume, alloy qualification, powder handling, monitoring, facility utilities, and post-processing cost before comparing with Nikon SLM, Renishaw, GE Additive, or Velo3D systems.
Use this EOS M 400-4 page to validate four-laser productivity, powder workflow, material qualification, and downstream production cost before comparing with other large AM platforms.
Confirm 400mm-class build volume, laser overlap strategy, recoater limits, nesting yield, and whether four-laser productivity matches the part geometry.
Ask which alloys are qualified, whether parameter sets are included, and how powder handling, sieving, inert gas, oxygen monitoring, and documentation are configured.
Compare the printer with heat treatment, depowdering, machining, inspection, facility utilities, monitoring, service, and operator training included in the same cost model.
Estimated range is a planning band. Confirm the final quote against included software, optics, safety package, installation, freight, training, and service terms.
Use $1200000-1800000 as the research range, then normalize every supplier quote to the same configuration.
Ask for sample results, service response time, warranty labor terms, consumable pricing, facility requirements, and acceptance criteria before approval.
Compare one same-power alternative, one lower-cost alternative, and one premium support option before treating the first quote as market price.
