About this product
The SLM 280 SS304 Build Platform is engineered to provide consistent, industrial-grade performance in metal additive manufacturing. Produced from corrosion-resistant 304 stainless steel and machined to strict flatness tolerances, this SLM 280 metal build plate ensures optimal powder spreading and reliable first-layer fusion.
Its 76.2 mm (3-inch) thickness provides substantial thermal mass, stabilizing heat flow during high-temperature LPBF builds. This reduces thermal distortion, internal stresses, and warping—particularly important for large or high-density parts.
As a direct-fit stainless steel build plate for SLM 280 systems, it installs seamlessly without modification. Each plate is fully inspected, cleaned, and ready for immediate installation to minimize downtime and maintain production continuity.
The SLM 280 SS304 Build Platform is ideal for service bureaus, industrial manufacturers, and R&D facilities requiring repeatable and cost-effective metal 3D printing performance.
