3D Metal Powder IMT MS1 15-53 Microns 5 kg

Engineered for industrial resilience, the IMT MS1 3D Metal Powder 15–53 µm 5 kg transforms digital designs into high-strength maraging steel parts. This powder is the backbone of advanced Additive Manufacturing, specifically tailored for the production of injection moulds, tool inserts, and aerospace components where structural integrity cannot be compromised. Thanks to its particle size distribution of 15–53 µm, it ensures compatibility with the majority of standard Laser Powder Bed Fusion (LPBF) systems.

Why professionals choose IMT MS1 3D Metal Powder

Tool-grade mechanical performance

The primary advantage of this material lies in its exceptional hardening capability. Whilst it prints with ease, post-process ageing transforms the alloy into a robust structure with a Rockwell hardness of 54–57 HRC. This specific characteristic makes the IMT MS1 3D Metal Powder 15–53 µm 5 kg indispensable for creating conformal cooling channels in injection moulds — geometries impossible to achieve with traditional CNC machining. Users obtain a tensile strength of 2000 MPa, ensuring that printed parts withstand immense cyclic loads without deformation.

Superior flowability and density

Consistency in layering is the key to defect-free metal 3D printing. With a sphericity of ≥ 85% and a Hall flow rate of ≤ 16 seconds, this powder spreads smoothly across the build platform. This high flowability minimises porosity and guarantees a tap density exceeding 4.2 g/cm³. For the operator, this translates into reliable, repeatable prints with uniform mechanical properties in all directions, significantly reducing the failure rate in manufacturing.

Exceptional surface finish

Post-processing is often a bottleneck, but this MS1 powder is formulated to simplify it. Printed parts achieve an impressive surface quality with a roughness (Ra) of approximately 0.01 μm after polishing, meeting the SPI:B1 standard. This level of finish is critical for mould manufacturing, where surface imperfections in the tooling transfer directly to the final plastic product. The material composition allows for a mirror polish, drastically reducing the time spent on manual finishing.
