Abstract The significance of this research lies in its potential to create an Additive Manufacturing technology of novel lightweight materials for industrial applications. The work reported here focuses on studies performed with low power fiber laser and investigates the feasibility of introducing high strength aluminium alloys and custom developed Al powder systems to the Selective Laser Melting (SLM) process. Al-Si powder alloys were used as a reference point. The understanding of the behaviour the investigated alloys is essential if the SLM process to be fully controlled for a manufacturing environment.

Additive manufacturing of metals (2016, background): “EN AW-7075 of the Al-Zn 7xxx series, contain highly volatile elements such as Zn, leading to turbulentmelt pools, splatter and porosity and are therefore not suited or not easy to use in AM, although current research efforts may promise AM of such alloys for the future [86].”

Review of Powder Bed Fusion Additive Manufacturing for Metals (2021, unknown): “[276] attempted to create their own custom high-strength aluminum alloy powder systems by blending together powders of aluminum (d50 = 35 μm) and copper (d50 = 3 μm), and also blending aluminum (d50 = 35 μm) and zinc (d50 = 5 μm) at various percentage concentrations.”
Additive manufacturing of metallic components – Process, structure and properties (2018, background): “Nearly all of the heat treatable aluminum alloys are welded using dissimilar filler metals near the Al-Si eutectic, and these alloys have proven to be popular alloys for AM processing [4,310,384,387,440,441].”
