IMT 304L Metal Powder – Stable Printing from Batch to Batch
IMT 304L spherical metal powder for 3D printing 15–53 μm, 5 kg packaging – a high-purity austenitic stainless steel powder material designed for industrial additive manufacturing. The 15–53 μm fraction is optimized for SLM / LPBF / EBM / DED technologies, ensuring stable layer formation, high printing repeatability, and the production of dense metal parts with complex geometry.
Why do 3D printers love IMT 304L?
The powder is produced by gas atomization in an inert atmosphere, which gives the particles a regular spherical shape, narrow size distribution, and a minimal number of satellite inclusions. This morphology ensures high powder flowability, uniform material distribution in the printer's working chamber, and dense layer packing. Good flowability and bulk density indicators allow for the formation of a stable powder layer, which is critical for obtaining high-quality products during laser melting.
Technological Features and Advantages
Alloy 304L belongs to austenitic stainless steels with a reduced carbon content (≤0.03%). The low carbon level prevents the formation of chromium carbides during melting and subsequent cooling, which reduces the risk of intergranular corrosion and increases the structural stability of printed products. The chemical composition is based on iron, 18–20% chromium, and 8–12% nickel, forming a stable austenitic structure with high corrosion resistance and good ductility.
Controlled granulometry of 15–53 μm provides a balance between printing resolution and equipment productivity. The fine fraction contributes to the formation of precise contours and thin walls, while the high sphericity of the particles ensures stable powder feeding in the recoating system and minimizes layer defects.
Delivery is carried out in a sealed 5 kg package, protecting the powder from moisture and oxidation during storage and transportation. The material is ready for use in industrial metal 3D printing systems and meets the requirements of high-precision additive manufacturing.

304L metal powder ensures the formation of dense parts with high mechanical strength and stable performance characteristics. The typical density of the material is about 7.8–7.9 g/cm³, which corresponds to the standard indicators of stainless steels of this class. Parts produced by additive manufacturing demonstrate high tensile strength, good impact toughness, and resistance to aggressive environments, including humid and chemically active media.
Areas of Use for IMT 304L Powder
Due to its high corrosion resistance and stable mechanical properties, IMT 304L powder is widely used for the production of functional parts: housings, brackets, heat exchange elements, valve components, medical instruments, chemical equipment elements, and engineering parts. The material is also suitable for prototyping and small-batch production where a combination of complex geometry and metal reliability is required.
