ASTM International, has recently published two new standards for additive manufacturing (AM) in collaboration with its AM committee (F42).
The first standard (F3571) provides guidelines for metal powder feedstock quality control and assessment. The guide aims to help manufacturers measure the quality of their feedstock, including the quantity of irregularly shaped powder particles, which can impact the flowability and mechanical properties of the finished product.
The second standard (F3572) provides a classification scheme for aviation parts produced through additive manufacturing. This classification system can serve as a consistent risk metric for these parts, enabling consistent processes for inspection, testing, and qualification.
“It is important to understand the risk associated with AM usage by understanding its consequence of failure, including the loss of intended function,” said Chul Park, ASTM International member and F42 Vice-Chair.
“The information can be beneficial in establishing consistent processes relative to a defined risk scale.”
These two new standards are expected to have a significant impact on the adoption and development of AM technology, particularly in the aviation industry. Furthermore, both standards align with the United Nations Sustainable Development Goal #9, which focuses on resilient infrastructure, sustainable industrialization, and innovation.
In conclusion, the publication of these new standards by ASTM International demonstrates the organization’s commitment to promoting the responsible and safe use of AM technology. The standards provide a consistent framework for the quality control and risk assessment of metal powder feedstock and aviation parts, and will likely serve as a catalyst for the continued growth and adoption of AM technology.
