Aluminum (AlSi Mg) is widely used in metal 3D printing due to its strength, lightweight, and excellent thermal properties. Unlike traditional shiny polished aluminum, 3D printed aluminum has a matte gray, slightly rough, and less clear surface. Aluminum alloy 3D printing services are quite popular in Metrixal's metal 3D printing services. The main materials are AlSi12 and AlSi10Mg.

Why do our clients choose Metrixal
The characteristics of aluminum alloy SLM are high processability and ductility, and good strength to weight ratio. Aluminum is a metal with good strength to weight ratio, high thermal conductivity, high electrical conductivity, low density, and natural weather resistance.
Aluminum alloys have excellent physical, chemical, and mechanical properties and have been widely used in many fields. However, the characteristics of aluminum alloys increase the difficulty of selective laser melting manufacturing. Such as easy oxidation, high reflectivity, and thermal conductivity.
At present, there are still many problems with SLM formed aluminum alloys, such as oxidation, residual stress, void defects, and density. These issues are mainly improved and resolved through measures such as strictly protecting the atmosphere, increasing laser power, and reducing scanning speed. At present, Al Si Mg alloy is the main material for SLM formed aluminum alloys, represented by AlSi12 and AlSi10Mg.
Al-Si12 is a lightweight additive manufactured metal powder with excellent thermal properties. AL-Si12 can be applied to thin-walled parts such as heat exchangers or other automotive components, as well as for aerospace industrial grade prototypes and production parts. The combination of silicon or magnesium makes aluminum alloys stronger and harder, making them suitable for thin-walled and complex geometric parts, especially in applications with good thermal performance and light weight.
