Printed aluminium — lightweight metal with geometry casting can't touch.
Aluminium 3D printing at KAD3D — Printed aluminium — lightweight metal with geometry casting can't touch.
AlSi10Mg is a casting-grade aluminium alloy printed by laser powder-bed fusion. It delivers genuine structural aluminium at roughly a third the weight of steel, with internal channels and lattices impossible to machine and excellent thermal conductivity for heat sinks and exchangers.
Printed aluminium is used for lightweight structural brackets, heat sinks, automotive and aerospace housings, and complex ducting where low weight and good thermal conductivity matter.
Typical applications include Heat exchangers, lightweight brackets, housings, and conformal-cooled tooling.
Produced with SLM, Aluminium 3D printing typically offers a tensile strength around 450 MPa, elongation at break near 8%, a density of 2.67 g/cm³, a hardness of ~119 HV and water absorption around 0%. Full technical data is listed in the table below.
For dimensional work, Aluminium AlSi10Mg supports a typical layer height or tolerance of ±0.10–0.20 mm or ±0.2% (pre-machining).
This makes Aluminium AlSi10Mg 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 Aluminium AlSi10Mg include Heat Treatment, Machining, Bead Blast and Polishing.
Standard turnaround for Aluminium AlSi10Mg is 20 business days, with an express option in 8–10 business days, from order confirmation and delivered Australia-wide.
Well suited to lightweight brackets and heat exchangers for Melbourne and Adelaide automotive and aerospace programs, where printed aluminium replaces heavier machined or cast parts.
An alternative to cast or machined aluminium for complex, low-volume parts.
Raw metallic and slightly grainy as-built; bead-blast, machine or anodise to the required finish. The most popular finish is T6 heat-treat for strength; bead-blast, then machine critical interfaces. Natural metal finish; bead-blast, machine, polish or anodise. 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.
