Marine-grade stainless, printed — corrosion resistance for life.
Stainless steel 316L 3D printing at KAD3D — Marine-grade stainless, printed — corrosion resistance for life.
316L is a marine-grade austenitic stainless printed by laser powder-bed fusion. It combines excellent corrosion resistance with strength and remarkable ductility for a printed metal, and polishes to a bright sanitary finish — ideal for marine, chemical and washdown duty.
316L stainless is used for marine hardware, food and beverage equipment, medical and surgical instruments, and corrosion-resistant brackets and manifolds — the same grade found in kitchens, boats and hospitals.
Typical applications include Manifolds, marine fittings, chemical-plant parts, and custom fasteners.
Produced with SLM, Stainless steel 316L 3D printing typically offers a tensile strength around 640 MPa, elongation at break near 40%, a density of 7.99 g/cm³, a hardness of ~89 HRB and water absorption around 0%. Full technical data is listed in the table below.
For dimensional work, Stainless Steel 316L supports a typical layer height or tolerance of ±0.10–0.20 mm or ±0.2% (pre-machining).
This makes Stainless Steel 316L a strong choice for parts that need metal, end-use production, heat over 100 °c, outdoor / uv-stable, chemical / moisture exposure, water-resistant and fatigue-resistant.
Finishing options for Stainless Steel 316L include Polishing, Machining, Bead Blast and Heat Treatment.
Standard turnaround for Stainless Steel 316L is 20 business days, with an express option in 8–10 business days, from order confirmation and delivered Australia-wide.
Marine-grade 316L is commonly chosen for coastal and marine hardware from Perth to the Gold Coast, where its corrosion resistance suits saltwater exposure and washdown environments.
An alternative to cast or machined stainless for complex, low-volume parts.
Raw metallic as-built; bead-blasts, machines and electropolishes to a bright, sanitary finish. The most popular finish is Bead-blast then electropolish or passivate for corrosion and sanitary duty; machine sealing faces. Natural metal finish; bead-blast, machine or polish. Maximum build size is up to 1100 × 625 × 625 mm.
SLM (selective laser melting) fully melts fine metal powder layer by layer to build dense, functional metal parts. You can read more about the SLM process on Wikipedia.
