Aluminum Alloy for 3D Printing Combines Benefits with Familiarity
IMTS 2018: Elementum 3D’s AL6061-RAM2% product is an aluminum 6061 material that achieves properties comparable to wrought 6061-T6 on existing laser powder-bed fusion equipment.
Elementum 3D’s AL6061-RAM2% product is an aluminum 6061 powder material said to achieve properties comparable to wrought 6061-T6 on existing laser powder-bed fusion equipment. Elementum 3D’s reactive additive manufacturing (RAM) technology has enabled the printing of production-quality 6061.
Aluminum 6061 is a commonly used alloy in the aerospace, automotive and defense industries. According to the company, advantages of the product include cost-effective print speeds and quality surface finish, combined with the familiarity of 6061.
A hybrid system combining metal 3D printing with machining gives the Marine Corps perhaps its most effective resource yet for obtaining needed hardware in the field. It also offers an extreme version of the experience a machine shop might have in adding metal AM to its capabilities.
Analyzing directed energy deposition and powder-bed fusion provides a thorough understanding of the extra machining necessary for a “near net shape” versus a “net shape” manufacturing process.
A new metal AM system for batches of end-use parts was designed to permit productivity and machine pricing comparable to a CNC machine tool.
