AM process × material library

High-temperature nickel superalloy printed by laser powder bed fusion. The default choice for turbine, gas-path, and high-stress thermal parts up to ~650 °C.

Aerospace-grade titanium printed by laser powder bed fusion. Highest strength-to-weight in the AM titanium family, with the deepest qualification record.

Precipitation-hardening stainless steel printed by binder jetting. Lowest cost per part of any qualified metal AM route, with 100s-of-parts batch economics.

EOS-style direct metal laser sintering of titanium. Functionally identical to L-PBF, with deep OEM parameter qualification and an exceptionally wide installed base.

Vacuum electron-beam melting of titanium. Lower residual stress and higher build rate than L-PBF, at coarser resolution. The default for monolithic Ti structures and orthopedic implants at volume.

The default aluminum for laser powder bed fusion. Light, weldable, thermally conductive — the workhorse for housings, heat exchangers, and topology-optimized brackets where mass matters more than absolute strength.

Austenitic stainless steel printed by L-PBF. Excellent corrosion resistance, ductile, biocompatible. The default AM stainless for marine, chemical, food, and medical environments.

Precipitation-hardening stainless steel printed by L-PBF. High strength, moderate corrosion resistance, and a wide age-hardening window. Common for tooling inserts and high-stress brackets.

Solid-solution-strengthened nickel superalloy. Outstanding corrosion resistance in marine, oil & gas, and chemical environments — without the aging cycle IN718 requires.

Cobalt-chromium-molybdenum alloy printed by L-PBF. Outstanding wear, biocompatibility, and high-temperature strength. The default for dental frameworks and orthopedic implants.

Blown-powder directed energy deposition of IN718. Higher build rate and larger envelope than L-PBF, ideal for repair, cladding, and large monolithic parts.

Wire-arc additive manufacturing of low-alloy carbon steel. The cheapest per-kilogram metal AM route, with build envelopes measured in meters. Ideal for marine, structural, and tooling.

HP Multi Jet Fusion of nylon 12. The default functional-plastic AM process: isotropic, dense, fast, and dimensionally consistent. Best-in-class for production polymer parts.

Stereolithography of a tough engineering photopolymer. Highest surface finish in AM and the best dimensional accuracy. Ideal for high-resolution functional prototypes, jigs, and fixtures.

Fused filament fabrication of polyether ether ketone. The highest-performance thermoplastic in AM: continuous-service to 250 °C, near-aerospace chemistry resistance, biocompatible.

EOS-qualified direct metal laser sintering of nickel superalloy. Functionally identical to L-PBF IN718 with the deepest installed-base of qualified parameter sets.

Solid-solution-strengthened nickel for gas-path components above 700 °C. The workhorse for printed combustor and aft-turbine hardware.

Ultra-high-strength tooling steel. The standard L-PBF alloy for conformal-cooled injection-mold inserts and short-run dies.

Electron-beam-melted cobalt-chromium for orthopedic implants. The dominant route for trabecular-surfaced acetabular cups and femoral stems.

Precipitation-hardened copper for high-conductivity thermal hardware. Standard for printed rocket combustion chambers and conformal heat sinks.

γ′-strengthened nickel for 700–870 °C service. The successor to Waspaloy and a leading candidate for next-gen turbine hot sections.

Directed energy deposition of 316L for large stainless structural parts and repair cladding. Multi-meter envelopes routine.

Glass-bead-filled nylon for stiff functional polymer parts at moderate cost. The MJF default when PA12 alone is too compliant.

Laser-sintered nylon. The legacy polymer-AM workhorse with the broadest qualified material catalog.

FAR 25.853-compliant PEI for aerospace interior parts. The dominant qualified FFF polymer for cabin and ducting hardware.
