Zare—an Italian additive manufacturing (AM) services bureau for prototypes and end-use parts—has invested in an SLM 280 2.0 selective laser melting (SLM) machine from Germany-based SLM Solutions for applications in the aerospace industry.
The SLM 280 2.0 has been installed at Zare’s headquarters in Boretto, northern Italy, and is operating alongside the company’s other AM machinery and ancillary equipment. Zare offers a broad range of AM technologies and a strong area of focus is the research and testing of materials. The SLM 280 2.0 is capable of processing high-performance metals, making it especially suitable for AM in the aerospace industry.
AlSi7Mg0.6 (A357) is one of two materials that Zare has been using on the SLM 280 2.0. High-quality parts that require little or no post-processing can be produced in A357 providing the machine is set correctly.
The second material is Scalmalloy, an aluminum-magnesium-scandium alloy developed by Airbus APWorks, a subsidiary of Airbus. Zare tests and defines processes in accordance with the UNI EN 9100:2009 standard to take full advantage of the machine’s build height for parts in Scalmalloy.
The SLM 280 2.0 affords a construction area of 280 x 280 x 365 mm3. It is a general consensus amongst AM industry experts that the greater the construction area, the greater the build quality. Zare is said to have been convinced by the 365 mm Z-axis afforded by the SLM 280 2.0, since it means the component can be better aligned and the number of support elements it requires are reduced. These factors, in turn, reduce unnecessary tension inside the component.
