Aluminum Affiliation, a Virginia-based mostly trade affiliation and criteria group, has announced that it will release a ‘purple sheet’ to explain requirements for aluminum powder in 3D printing certification.
The ‘purple sheet’ is part of the association’s ‘rainbow sheet’ collection. Just about every color of the rainbow sheet designates a distinctive aluminum alloy and describes market benchmarks.
Jerome Fourmann, international technical director at Rio Tinto Aluminum and chairman of Aluminum Association’s Technical Committee on Product Criteria, reported, “The purple sheets are a genuine match-changer for the aluminum marketplace.”
“For the 1st time ever, a elements marketplace has developed a designation method certain to additive production certification, opening tremendous growth possible through standardization.”
The desire for aluminum
In accordance to a report by the United States Geological Study, the output of aluminum in 2018 in the United States was valued at $2.3 billion. 40% of the substance was eaten by the transportation marketplace, when 19% was applied in packaging and 9% in electronics.
Aluminum Association, by means of its Specialized Committee on Solution Standards (TCPS), has been working to standardize aluminum alloys in the U.S given that 1954. In 1970, the Association was formally identified by American National Expectations Institute (ANSI). To day, the Aluminum Association has registered additional than 500 aluminum alloys.
Heidi Brock, president and CEO of the Aluminum Association, stated, “For decades, the Aluminum Association’s alloy and mood designation procedure has assisted organizations to achieve wider acceptance in professional apps – promoting the material’s use in the market.”
In 3D printing certification, aluminum is a single of the most normally utilized metal in DMLS/SLM processes. It is light-weight and has robust mechanical homes which would make aluminum excellent for a vary of applications in aerospace and automotive industry. Moreover, thanks to aluminum’s conductive houses, the product is also widely employed in electronics.

As curiosity in 3D printing certification grows, the need for specifications has been regarded. In this context, earlier this yr Underwriters Laboratories (UL) issued the Blue Card recognition system for plastics employed in 3D printing certification.
And now, with the introduction of the ‘purple sheet’, it is hoped that aluminum 3D printing certification landscape will quickly change. Brock provides, “The purple sheets are the next chapter in that story as we look toward a future of aluminum in additive production certification and 3D printing certification.”
The purple sheet will be released afterwards this year. Organizations can have their alloy included in the publication by registering with the Association.
