What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.
About this product
The M400 SS316 Build Platform is crafted from premium 316 stainless steel to provide enhanced corrosion resistance and industrial-grade reliability for EOS M400 and M400-4 systems. With a large 360×400mm surface and 76.2mm thickness, this stainless steel building platform ensures optimal thermal stability, reducing warping and maintaining dimensional accuracy for reactive or chemically challenging metal powders.
Precision CNC machining, stress relief, and surface grinding guarantee flatness across the platform, ensuring reliable first-layer adhesion, stable recoater operation, and minimal print failures. Engineered for high-volume production, medical device manufacturing, and industrial LPBF workflows, this build platform delivers consistent, repeatable results with long-term durability.
Key Features & Benefits

- Large 360×400mm Build Surface: Maximize productivity by printing larger parts or multiple components in a single build.
- Optimal Thermal Mass (76.2mm): Provides consistent heat distribution to reduce warping and improve dimensional accuracy.
- Precision-Ground Surface: Ensures perfect first-layer adhesion and minimizes print failures and material waste.
- Direct EOS M400 Compatibility: OEM replacement plate guarantees seamless fit and reliable performance for EOS M400 and M400-4 systems.
WHY CHOOSE THE M400 SS316 BUILD PLATFORM?
- Enhanced Corrosion Resistance: Maintains structural integrity in chemically aggressive or humid environments.
- Long-Term Durability: Resistant to pitting, crevice corrosion, and material degradation over extended production runs.
- Versatile Material Compatibility: Supports stainless steels, tool steels, aluminum alloys, nickel-based alloys, and general-purpose titanium.
- Industrial Reliability: Designed for continuous, high-volume LPBF manufacturing.
Ideal For
- Chemical & Marine Applications: Components exposed to saltwater, chemicals, or high-humidity conditions.
- Medical Device Manufacturing: Parts requiring superior corrosion resistance and durability.
- High-Volume Production: Environments where plate longevity and reliability are critical.
- Reactive Material Printing: Applications involving challenging or reactive metal powders.
Upgrade your EOS M400 with a 316 stainless steel build plate for superior corrosion resistance and reliable, large-format 3D printing performance.

Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
