Comment on standards published in 2020

In 2020, 5 standards were finally published. This was achieved by the great commitment of the Working Group leaders, the Project Leaders and the employees of DIN, CEN, ISO and ASTM, who, despite the difficult working conditions caused by Corona, have driven the worldwide standardization work forward in a focused manner. As a result, additional international standards are now available, which the additive manufacturing industry urgently needs for its further growth. The following is a brief introduction to the standards published in 2020:

• MATERIAL EXTRUSION
  With ISO/ASTM 52903-1:2020 and ISO/ASTM 52903-2:2020, first international standards on Material Extrusion processes are now available. Part 1 covers feedstock material and part 2 corresponding process equipment. This is a significant milestone to enable extrusion-based technologies to further gain market relevance.
• SYSTEM PERFORMANCE AND RELIABILITY
  ISO/ASTM 52941:2020 covers an acceptance test for laser metal powder-bed fusion machines for metallic materials for aerospace application. Therefore, it eases and supports certification procedures in the aerospace industries. Though being specifically developed for the aerospace needs, it can also be used in other industries, if suitable.
• DATA FORMAT
  ISO/ASTM 52915:2020 is an international standard covering a specification for AMF-file format, version 1.2. AMF – Additive Manufacturing File Format – is a standardized open data format specifically designed for the needs of Additive Manufacturing processes. It is technically by far more suitable than the quasi-standard format STL but has not yet gained industrial significance. With the 2020-released AMF version 1.2, described in ISO/ASTM 52915:2020, this is likely to change.
• QUALIFICATION PRINCIPLES
  As Additive Manufacturing technologies are increasingly used in production, there is a demand for qualified staff. For that reason, six international standards are currently under development within ISO/TC 261 to provide qualification principles for several profiles. ISO/ASTM 52942:2020 is the first published international standard of a series of qualification principle standards to be followed in 2021. ISO/ASTM 52942 covers requirements for machine operators of laser metal powder-bed fusion machines and equipment used in aerospace applications.
• DESIGN
  ISO/ASTM TR52912:2020 is an international Technical Report that provides an overview on functionally graded Additive Manufacturing. As an ISO/ASTM Technical Report (TR) it is an informative and not normative document.
