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.

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

  • Premium 316 Stainless Steel: Offers enhanced corrosion resistance for printing in high-humidity environments, with reactive metal powders, or for components exposed to chemicals or marine conditions.
  • 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.
