SLM Solutions partnered with Honeywell to qualify 3D-print aluminium aerospace parts. The ongoing collaboration aims to set a new milestone for the material used to produce aerospace components with a high layer thickness to be more efficient in terms of time and cost.

Honeywell first began exploring AM aluminium parts and parameters last year using an increased layer thickness of 60 and 90 µm on a quad-laser SLM 500 Selective Laser Melting Machine. SLM Solutions initially provided Honeywell with generic aluminium parameter sets to complete material qualification but development of these new parameter sets using a layer thickness of 60 µm and 700 W lasers is said to have now reached an “important milestone”, citing material properties which exceed that of conventional die-cast parts and overall metallic properties for aerospace.
The material, a new beryllium free version of AlSi7Mg0,6 (A357), is highly sought in aerospace due to its lightweight properties, corrosion resistance and desired mechanical properties, such as high-strength across a wide temperature range in comparison to conventional aluminium alloys. It also provides great weldability and can be readily post-processed via a number of techniques.
