EOS M290 SS304 Build Plate | 50mm Stainless LPBF Platform
Request a custom quote — we manufacture precision build plates for most metal AM systems.
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.
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.
Key Features & Benefits of sS304 Build plate for eOS m280/m290
- Optimized 50mm Profile:
Reduces thermal mass for faster heat-up and cool-down cycles, improving production throughput and lowering energy consumption — ideal for high-efficiency metal 3D printing environments. - Durable 304 Stainless Steel Construction:
Provides exceptional strength, corrosion resistance, and dimensional stability, making it a reliable steel build plate for repeated use with steel-based powders and other metal materials. - Precision-Ground Surface:
Ensures perfect flatness across the 3D printer build plate, improving first-layer adhesion and ensuring consistent results across every batch. - Dual Compatibility:
Fully certified for both EOS M280 and EOS M290 systems, simplifying inventory management and offering greater operational flexibility. - Cost-Effective Performance:
Combines the quality of a genuine metal printing platform with a competitive price, making it ideal for prototyping, R&D, and medium-volume production.
Why Choose a 50mm Build Plate?
- Faster Cycle Times: Less mass equals quicker heating and cooling for improved efficiency.
- Optimized Thermal Stability: Retains sufficient heat distribution for most additive manufacturing processes.
- Lightweight & Easy to Handle: Easier installation and safer operation.
- Lower Operating Costs: Excellent balance of performance, price, and reliability.
Ideal For
- Research & Development: Perfect for testing new alloys and titanium builds.
- Prototyping & Testing: Achieve fast iteration with reliable performance.
- Educational Institutions: Durable and accessible 3D printing base plate for academic use.
- Medium-Volume Production: Reliable throughput for everyday metal 3D printing operations.

Unedited feedback from customers who reorder EOS M290 SS304 Build Plate | 50mm Stainless LPBF Platform.
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.
Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.
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.
