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 EOS M290 SS304 Build Plate is a precision-machined 304 stainless steel platform for EOS M280/M290 laser powder bed fusion (LPBF) systems. Its 252×252×50 mm (9.92×9.92×1.97 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 $580.

Why production teams choose this plate

Spec-backed reasons to run a machined, inspected plate over raw stock or a worn platform.

✓
Dependable stainless, lower cost

304 delivers reliable corrosion resistance and easy machinability for general stainless and tool-steel builds — a cost-effective production workhorse.

✓
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 M280/M290 spec

Each plate is CNC-machined to the EOS M280/M290 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.

01
Machine to spec

Each plate is CNC-machined from certified 304 stainless steel stock to the EOS M280/M290 clamping and recoater pattern.

02
Stress-relieve & grind

Every plate is stress-relieved, then precision-ground to a flatness tolerance before it ships — no field-lapping required on install.

03
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.

What is the EOS M290 SS304 Build Plate?
The EOS M290 SS304 Build Plate is a precision-machined 304 stainless steel build platform designed for EOS M280 and EOS M290 LPBF (Laser Powder Bed Fusion) metal 3D printers. It provides a flat, stable surface for reliable first-layer adhesion and consistent metal additive manufacturing while meeting the dimensional requirements of EOS systems.
Which metal 3D printers is this build plate compatible with?
This build plate is designed specifically for the EOS M280 and EOS M290 metal 3D printers. Additive Plus also manufactures custom build plates for other LPBF systems, including Renishaw, SLM Solutions, Nikon, Trumpf, Additive Industries, and many other industrial metal 3D printers.
What material is the build plate made from?
The build plate is manufactured from certified SS304 stainless steel. This material offers excellent corrosion resistance, reliable machinability, and long service life, making it a dependable choice for LPBF production and research applications.
What are the dimensions of the EOS M290 SS304 Build Plate?
A precision-ground, flat build plate helps ensure consistent first-layer adhesion across the entire build area. Proper flatness reduces the risk of recoater collisions, improves dimensional accuracy, and minimizes print failures caused by uneven surfaces.
Why is build plate flatness important for LPBF printing?
A precision-ground, flat build plate helps ensure consistent first-layer adhesion across the entire build area. Proper flatness reduces the risk of recoater collisions, improves dimensional accuracy, and minimizes print failures caused by uneven surfaces.
Is the build plate stress relieved before shipping?
Yes. Every build plate is stress relieved before precision grinding and final inspection. This process helps minimize internal stresses, improves dimensional stability during printing, and provides more consistent performance over repeated build cycles.
Can the build plate be resurfaced and reused?
Yes. The 50 mm profile provides sufficient material thickness for multiple resurfacing operations. After several print cycles, the plate can be re-machined to restore flatness, extending its service life and reducing replacement costs.
What materials can be printed on this build plate?
The SS304 build plate is commonly used for printing stainless steels, tool steels, and other ferrous alloys on EOS LPBF systems. It is also suitable for research, parameter development, and general-purpose metal additive manufacturing applications.
Does every build plate include material certification?
Yes. Every build plate is supplied with material certification verifying the stainless steel grade along with dimensional inspection and flatness verification. This documentation supports quality assurance and production traceability.
What is the difference between Express and Standard delivery?
The Express option typically ships within 2–3 weeks, while the Standard option ships within 6–8 weeks at a lower cost. Both options are manufactured to the same quality standards and undergo identical machining and inspection processes.
Can I order custom build plates?
Yes. Additive Plus manufactures custom metal build plates for most industrial LPBF systems. Custom options include alternative materials, thicknesses, mounting patterns, threaded holes, engraved identification, alignment features, and customer-specific dimensions.
Can Additive Plus manufacture build plates from other materials?
Yes. In addition to SS304 stainless steel, Additive Plus manufactures build plates from materials such as SS316 stainless steel, Ti-6Al-4V titanium, aluminum alloys, tool steels, and other customer-specified materials based on machine and application requirements.
Who should use the EOS M290 SS304 Build Plate?
This build plate is ideal for aerospace manufacturers, research laboratories, universities, medical device companies, service bureaus, and production facilities operating EOS M280 or EOS M290 metal 3D printers that require reliable, production-ready build platforms.
How do I know if I need a replacement build plate?
A replacement is recommended when the existing build plate can no longer maintain flatness after resurfacing, shows excessive wear or damage, or no longer provides consistent first-layer adhesion. Replacing worn build plates helps maintain print quality and reduce build failures.
Can I purchase multiple build plates for production?
Yes. The EOS M290 SS304 Build Plate is available in single or bulk quantities, making it easy for production facilities to maintain multiple build plates and reduce machine downtime between print jobs.
Can I speak with a manufacturing engineer before ordering?
Yes. Additive Plus provides direct access to manufacturing engineers who can help you select the correct build plate, review machine compatibility, recommend custom configurations, and answer questions about materials, dimensions, and production requirements before you place an order.
