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.
Raw metallic and slightly grainy as-built; bead-blast, machine or anodise to the required finish.
Natural metal finish; bead-blast, machine, polish or anodise.
Lead times are indicative and start from order confirmation. Actual turnaround varies model by model, depending on part geometry, print time, quantity and shipping location. Express service incurs an additional charge. Express availability is subject to current machine capacity — please confirm when ordering.

Parts printed in Aluminium AlSi10Mg in SLM can be finished a number of ways at KAD3D, from a clean functional surface to a fully painted, display-ready result. The treatments below are the ones we most often apply to this material.
Most popular finish: T6 heat-treat for strength; bead-blast, then machine critical interfaces.
To make material costs easy to compare, KAD3D prints the same standard model — the #3DBenchy — in every material. The price shown is what that identical benchmark part costs in Aluminium AlSi10Mg, so you can weigh materials against each other on a genuine like-for-like basis before uploading your own file.
Benchmark price is a guide for comparison only; your part is quoted on its own size, geometry and finishing. Upload your model for an exact price.
