EOS M400 SS316 Build Plate | M400 SS316 Build Platform for Metal 3D Printing
What your process engineer actually checks
Flat, stable, and ready for production
Every build plate is manufactured from certified material, precision-machined, and inspected before shipment. Critical dimensions, flatness, thickness, and mounting features are verified to ensure reliable installation and repeatable print results.
Machine-ready compatibility
Build plates are available for EOS, Renishaw, SLM Solutions, Nikon, Trumpf, Additive Industries, and other metal AM platforms. Need a custom mounting pattern or proprietary format? We can manufacture to your drawing.
The EOS M400 SS316 Build Plate is a precision-machined 316L stainless steel platform for EOS M400 laser powder bed fusion (LPBF) systems. Its 360×400×73.66 mm (14.17×15.75×2.9 in) profile is stress-relieved and ground flat for repeatable first-layer adhesion, and it ships in two build speeds — Express in 2–3 weeks or Standard in 6–8 weeks — from our California shop. From $2,550.
Why production teams choose this plate
Spec-backed reasons to run a machined, inspected plate over raw stock or a worn platform.
Corrosion resistance where it counts
316L adds molybdenum over 304 for stronger resistance to pitting and chloride attack — useful in humid shops or around cleaning chemicals.
Ground flat for consistent first layers
CNC-machined and precision-ground to a tight flatness tolerance so the first fused layer bonds evenly across the full platform — fewer recoater collisions, fewer failed builds.
Substantial profile, more regrind life
A thick starting plate leaves more material to face off and re-flatten after each build cycle before it is retired — more usable life than a thin, single-use plate.
Machined to EOS M400 spec
Each plate is CNC-machined to the EOS M400 clamping and recoater mounting pattern, so it drops into your machine without field-lapping.
How we get it to your build chamber
Every plate ships as a finished, inspected platform — not raw stock.
Machine to spec
Each plate is CNC-machined from certified 316L stainless steel stock to the EOS M400 clamping and recoater pattern.
Stress-relieve & grind
Every plate is stress-relieved, then precision-ground to a flatness tolerance before it ships — no field-lapping required on install.
Inspect & ship
Flatness is checked on the finished plate. Choose your speed at checkout — Express in 2–3 weeks, or Standard in 6–8 weeks at lower cost.
