The current lack of standards in additive manufacturing (AM) obstructs the use of qualification and certification schemes and prevents the generalisation of AM as a mainstream manufacturing technique, particularly in those fields where the certification is mandatory (medical, aeronautical, automotive, etc). This post summarises the joint efforts carried out by various international organisations to develop new standards in accordance with the priorities of stakeholders. The standards currently applied with regard to other conventional manufacturing processes (machining, welding, casting, polymer processing, etc.) or materials (metals, plastics, ceramics) are not always suitable for AM technologies. AM, which involves different technologies, has particular materials and operational parameters that show great influence on the final quality and properties of the part. Challenges due to lack of standards were identified in the following areas [1]:
Some recommendations [2] on standards and certification were identified:
SASAM [2] provided a list of priorities for standards and a road map with a time schedule:
The latest situation is that of joint standard development by ISO–ASTM for AM. Several standards have been provided to the AM community. These new AM standards are expected to
A consensual structure will provide, in accordance with the priorities requested by stakeholders, a solid basis to provide useful standards in line with the spectacular development of AM technologies. The first challenge of this standardization process is to
The second challenge is an efficient coordination with other committees for standardization, working in materials and processes in order to avoid unnecessary overlapping with more general standards. The possibility of AM-specific standards jointly coordinated by ISO and ASTM opens new opportunities for the global spread of AM among countries and companies. References
