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.

About this product
The EOS M290 SS304 Build Plate is a precision-machined stainless steel platform engineered for stable, repeatable LPBF metal printing. Designed for EOS M280 and M290 systems, it provides optimized thermal performance and reliable first-layer adhesion across a wide range of materials.
Manufactured from high-grade 304 stainless steel, this metal build plate is CNC machined, stress-relieved, and precision-ground to tight flatness tolerances. The 50mm optimized thickness reduces unnecessary thermal mass, allowing faster heat-up and cool-down cycles compared to heavier standard plates.
From an engineering perspective, the EOS M290 SS304 Build Plate balances rigidity, dimensional stability, and thermal efficiency. It integrates seamlessly with standard EOS clamping and recoater systems, ensuring consistent powder spreading and repeatable builds.
Compared to thicker or non-optimized platforms, this stainless steel build plate improves production throughput while maintaining the structural stability required for industrial metal additive manufacturing.
