Aurora nails multi-layered 3D print testing

Aurora Labs has successfully completed a testing program of samples of corrosion-resistant, 316L stainless steel using the company’s patented multi-layered concurrent printing technology known as “MCP” technology. The independent test results have exceeded ASTM standards in tensile and yield strength and the company said this was an important step towards demonstrating that its multi-layered concurrent proprietary printing technology is viable and efficient.

The company said the tests were an important step towards demonstrating to the market that Aurora’s proprietary MCP technology is a viable method of metal 3D printing. It said that the MCP technology printed multiple layers in a single pass which could increase production speeds over traditional laser bed fusion printers.

Aurora said the tests were conducted against “ASTM” standards at an accredited test laboratory of the Perth-based National Association of Testing Authorities on coupons printed in stainless steel 316L using the MCP technology. ASTM International is one of the world’s largest international standards development organisations that defines and sets standards for many global industries.

This level of validation testing being undertaken by Aurora is a part of the company’s plan to build a data set of results from a combination of machine settings and inputs, including powder, to deliver predictable and repeatable results. Management said it expects that this effort will allow MCP printed parts to be used instead of traditional cast and wrought metals.

316L stainless steel is a non-rusting, higher quality stainless steel than its lower quality 304 counterpart.

Aurora Labs Managing Director, David Budge said: “This is an important milestone in validating Aurora’s RMP technology. These encouraging preliminary test results, combined with our recently signed DNV-GL agreement and delivery of print samples to prospective clients demonstrate Aurora’s progress towards commercial release of the RMP1 printer.”

Aurora said its MCP technology is one of the most disruptive changes to the 3D printing market in recent times given that it breaks the single layer barrier, printing multiple layers concurrently and delivering both increased speed and accuracy of production of parts.
