Australian metal 3D printing company Aurora Labs has announced a significant step forward in the validation of its Multi-Layer Concurrent Printing (MCP) process. As part of the process validation, the company has conducted independent testing of sample parts 3D printed from Stainless Steel 316L. Recent results demonstrated that the samples exceeded ASTM standards in tensile strength and yield strength.

The independent tests were conducted at a laboratory in Perth that is accredited by the National Association of Testing Authorities, Australia (NATA). The positive results so far show real promise for Aurora’s MCP metal 3D printing method.

MCP technology stands out within the spectrum of existing metal AM processes in that it is capable of printing multiple layers in a single pass—unlike laser bed fusion which prints layer upon layer. The multi-layer approach has the potential to drastically speed up production times for metal parts without sacrificing accuracy and precision. According to Aurora Labs, its MCP technology results in “dense, fully melted metal parts.”

To accelerate the development of its MCP technology, Aurora Labs has undertaken external validation testing in an effort to establish a parameter properties dataset. This dataset will comprise test values gathered through mechanical, microscopic and x-ray tests, among others, for a given specification. The goal of the tests is to achieve repeatable, consistent print results for specific combinations of material type and print settings.

The recently announced test results shows that sample parts made from Stainless Steel 316L powder exceeded ASTM Standards A479/276 and f1384-16 in Ultimate Tensile Strength and Yield Strength. Further, the company says the tests clearly showcase that its MCP process meets or exceeds relevant engineering standards for designing parts.

Down the line, the data gathered from the tests will support the commercialization of Aurora’s MCP-based 3D printing system, the RMP-1. In October, Aurora Labs supplied its first RMP-1 Beta 3D printer to AdditiveNow, an Australian provider of training programs as well as engineering design and sample part 3D printing services.

“This is an important milestone in validating Aurora’s RMP technology,” said David Budge, Managing Director at Aurora Labs. “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.”
