ASTM International to create LPBF standard

Share this on social media:

A standard that could help quickly assess the quality of additively manufactured parts, as well as the performance of the laser powder bed fusion (LPBF) machines that print them, is being developed by ASTM International’s additive manufacturing technologies committee.

The proposed standard aims to use off-the-shelf tools to quickly generate qualitative data related to dimensional accuracy and material strength, both of which serve as indicators of the health of additive manufacturing machines and parts.

The committee is currently welcoming representatives of industries, universities, and research facilities that work in additive manufacturing technology to participate in upcoming round-robin experiments to assess the robustness of the proposed standard.

The technical point of contact of this work item, Jonathan Pegues of Sandia National Laboratories, said that the standard could ultimately help manufacturers, laboratories, government agencies, and other stakeholders that produce LPBF parts for structural applications. The applicability of this method can be potentially extended to other additive manufacturing systems.

In 2019 ASTM International also revealed it was developing standards for directed energy deposition, another additive manufacturing process, in partnership with Innovate UK, the British Standards Institution, and the UK Manufacturing Technology Centre.
