3D Printing Aluminium.

Aluminium 3d printing.

3D Printing in Aluminium. Strong & Durable Service.  

3D print your designs in Aluminium and choose from a range of alloys to suite your application. 

Aluminium is 3D printed using the DMLS (Direct Metal Laser Sintering) or SLM process.  A very fine metal powder is melted with a laser to produce your design layer by layer. Once your design is complete any support structures are removed and any finishing completed. Unused powder is recycled for use on the next model.

3D Printing in Aluminium can work out more cost effective than traditional 'subtractive' processes, especially where you have complex or intricate designs.  Extra complexity does not add to the price of manufacture as it might with traditional manufacture.

Aluminium AlSi10Mg

AlSi10Mg is our default Aluminium material for 3d printing.

The alloy gives a homogeneous and almost pore free structure and is impermeable. AlSi10Mg offers high hardness values, and good dynamic strength. The nature of the DMLS or SLM process means that the mechanical properties of finished parts are better than traditional casting processes.


AlSi10Mg is ideal for design applications where you need good mechanical properties and low weight. Components 3d printed in the alloy can be subjected to a range of post build finishing processes, including heat-treatment, machining, welding, eroding, micro-blasting, polishing and coatings.

Aluminium AlMgSc ( Scalmalloy®RP )

AlMgSc ( Scalmalloy®RP ) has been specifically designed for aerospace applications. The specific blend of elements gives AlMgSc improved strength over traditional casting alloys.

The strength of components can be considerably increased with a precipitation hardening process, to give a performance which is twice that of T6 heat treated AlSi10Mg.

Finally, parts produced from AlMgSc may be welded and exhibit excellent corrosion resistance.


With high strength and low density the AlMgSc is especially suited to demanding applications, including Motor sport, Vehicle manufacture and Aerospace.

With a strength to density ratio comparable to titanium the alloy is also very tough, making it ideal for safety critical designs.
