Additive Manufacturing Materials

Metal Powders for 3D Printing

Metal powders are suitable for components that require mechanical strength, heat resistance, corrosion resistance, thermal conductivity, or lightweight design. Common material directions include stainless steels, tool steels and high-strength steels, aluminum alloys, titanium and titanium alloys, nickel-based superalloys, cobalt-based alloys, cobalt-chromium-molybdenum alloys, copper alloys, and specialty alloys for materials research.

Metal additive manufacturing materials are widely considered for aerospace, automotive, energy, medical, tooling, thermal management, industrial equipment, and functional prototype applications. Depending on the process, key considerations include particle size distribution, sphericity, flowability, chemical composition, oxygen control, packaging, and process compatibility.

Ceramic Powders for 3D Printing

Ceramic powders are suitable for applications requiring high hardness, wear resistance, high-temperature stability, corrosion resistance, electrical insulation, or biocompatibility. Oxide ceramics, non-oxide ceramics, bioceramics, and functional ceramic systems can support the development of heat-resistant structural parts, electronic and insulating components, precision devices, medical research materials, and high-temperature process applications.

When selecting ceramic materials, consider sintering shrinkage, particle morphology, dispersion behavior, binder compatibility, debinding and sintering conditions, and the required density, dimensional accuracy, and surface finish of the final component.

Polymer Powders for 3D Printing

Polymer powders are suitable for lightweight prototypes, functional housings, fixtures, consumer products, flexible components, and customized low-volume parts. Different polymer systems can offer varied combinations of toughness, rigidity, impact resistance, chemical resistance, temperature capability, flexibility, and surface appearance.

Powder-based polymer materials may include nylon systems, elastomers, high-performance engineering polymers, and modified polymer formulations. Select materials according to the printing process, part thickness, mechanical load, service temperature, color requirements, and intended finishing method.

Composite Powders for 3D Printing

Composite powders combine a matrix material with reinforcing, filler, or functional components to create a more targeted balance of properties. They can support projects requiring improved stiffness, lower weight, wear resistance, thermal conductivity, electrical conductivity, or specialized structural and functional behavior.

Composite material selection depends not only on composition, but also on powder uniformity, interfacial bonding, processing stability, and the intended post-processing route. For projects with highly specific performance requirements, define the component’s primary function and validation target before selecting a material system.

Key Points to Confirm Before Selection

What to Confirm	Why It Matters
Printing process and equipment	Different processes have different requirements for particle size, flow behavior, thermal response, and feed method.
Operating environment	Temperature, load, corrosive media, friction, and electrical requirements influence material selection.
Target performance	Define whether strength, low weight, heat resistance, conductivity, insulation, flexibility, or surface quality is the priority.
Post-processing route	Heat treatment, sintering, machining, polishing, blasting, and coating can affect the preferred material choice.
Part size and geometry	Wall thickness, internal channels, support strategy, and design complexity can affect printability.
Validation requirements	Research, prototyping, and application validation may require different material specifications and test plans.
