300M is a chromium-molybdenum-vanadium alloy steel (AISI 4340-type) used in high-strength aerospace applications including landing gear, fasteners, and structural components, offering tensile strengths of 1650–1900 MPa with excellent fatigue resistance and fracture toughness when properly heat-treated.
316L stainless steel printed by metal binder jetting is the low-carbon, molybdenum-bearing austenitic steel formed by depositing liquid binder onto a powder bed, with no melting during the build. The green part is fragile and porous, so it is depowdered, debound and sintered, and sintering provides its final density. Parts shrink considerably in sintering, so geometry is compensated and slender features may need setters to limit distortion. Residual porosity and surface roughness are typically higher than in wrought material, but fusion-type residual stress is avoided. It is used for corrosion-resistant fittings, housings and fluid-handling parts with complex shapes.
Desktop Metal 316L Stainless Steel (Shop System) is that maker's grade of low-carbon austenitic 316L stainless steel for binder jetting, used in the sintered condition. Parts are printed as green bodies of binder-held powder, then depowdered and furnace-sintered. They shrink substantially as they densify, so designs must allow for shrinkage and sagging. The sintered structure is equiaxed austenite with some residual porosity, more uniform between build directions than laser-melted 316L, and it needs no supports and carries little residual stress. Typical uses are production runs of small brackets, fluid fittings, hardware and tooling parts that would otherwise be machined, cast or metal injection molded.

316L stainless steel made by bound metal deposition is the low-carbon, molybdenum-alloyed austenitic grade, printed from metal-filled polymer filament and then debound and sintered into metal. The green part is printed oversize to allow for sintering shrinkage, and supports or a ceramic interface layer are often needed to limit distortion in the furnace. Sintered parts are largely dense but can keep fine residual porosity, with layer lines and some anisotropy between build directions. Critical surfaces are usually machined or polished. Typical uses are corrosion-resistant fixtures, tooling, housings and low-volume fluid-handling parts.
Desktop Metal 316L Stainless Steel (Studio System 2) is the maker's 316L austenitic stainless steel for bound metal deposition, printed from rods of metal powder in a polymer and wax binder and used in the sintered condition. Parts are extruded oversize, then debound and sintered, shrinking toward near-full density, with a ceramic interface layer letting supports separate after sintering. Sintering rather than melting gives an equiaxed austenitic structure free of melt-induced residual stress, but leaves some porosity, visible layer lines and a surface that often needs machining on critical faces. Parts serve as prototypes, jigs, fixtures and low-volume functional parts.

Markforged 316L Stainless Steel is a sintered grade of low-carbon, molybdenum-bearing austenitic stainless steel made by Bound Metal Deposition (BMD), a material extrusion process. Metal-powder-filled polymer filament is extruded, then the part is debound and furnace sintered, shrinking substantially, so it is printed oversize. The sintered part has an equiaxed austenitic structure with some residual porosity, low residual stress, visible layer lines and somewhat direction-dependent properties, so critical surfaces are usually machined. It is used for jigs, fixtures, tooling, brackets and low-volume corrosion-resistant parts.

316L stainless steel printed by fused deposition modeling is the molybdenum-bearing austenitic grade made from filament in which fine steel powder is bound in a polymer. The extruded green part is debound and then sintered to densify the metal, so the route resembles metal injection molding more than melt-based metal printing. Layer and infill structure leave some anisotropy between build directions, sintering shrinks the part substantially, and residual porosity and a layered surface are typical; overhangs need supports. It is used for jigs, fixtures, tooling, functional prototypes and low-volume corrosion-resistant parts with complex geometry.
BASF Forward AM Ultrafuse 316L is a filament of 316L stainless steel powder in a polymer binder, printed by fused deposition modeling into a green part that becomes solid metal only after debinding and sintering. The binder is removed catalytically, and sintering then densifies the part with substantial shrinkage that the design must compensate, leaving an austenitic structure with some residual porosity. Parts show layer lines and somewhat lower properties across layers than along them, and critical surfaces usually need machining. The grade is used for prototypes, tooling, jigs, fixtures and low-volume corrosion-resistant parts.

BASF Forward AM Ultrafuse 316L, sintered, is 316L austenitic stainless steel printed by material extrusion from a filament of metal powder in a polymer binder, then debound and sintered. The binder is removed from the printed green part, typically by catalytic debinding, and furnace sintering fuses the powder into a near-dense metal part, with substantial shrinkage that the print is scaled up to offset. Sintered parts keep the layer texture of extrusion and some residual porosity, and surfaces that need tight tolerances are usually machined. Typical uses are jigs, fixtures, tooling, brackets and low-volume functional parts that need the corrosion resistance of 316L.

316L stainless steel printed by laser powder bed fusion is the low-carbon, molybdenum-alloyed austenitic grade, built by selectively melting fine powder layer by layer. Rapid solidification gives a fine cellular sub-grain structure and columnar grains growing along the build direction, so horizontal and vertical builds can differ. Parts carry high residual stress, so they are built on a plate with supports and stress relieved before removal. Surfaces are rough as printed and are often machined or polished, and small pores can remain unless the part is densified. Typical uses are corrosion-resistant manifolds, heat exchangers, fluid-handling parts, tooling and lightweight brackets.

7050 aluminum T77511 is a high-strength Al-Zn-Mg-Cu alloy in overaged condition with controlled stretching, providing tensile strength around 470–500 MPa with improved stress-corrosion cracking (SCC) resistance compared to T7351, suitable for highly stressed aerospace structures including aircraft fuselage and wing components.
7075-T6151 is a high-strength aluminum-zinc alloy (with copper and magnesium) solution heat-treated and artificially aged with controlled stretching, delivering tensile strength of 505–530 MPa and improved fracture toughness and stress-corrosion cracking (SCC) resistance compared to T6, suited for critical aerospace and defense structural applications subject to sustained tensile loading. The T6151 condition is specified for components where the controlled residual compressive stress from stretching is beneficial for fatigue life and crack propagation resistance.
