ASTM Proposes New Standards for Metal 3D Printing
8/29/2014

Producing high-quality end-production metal parts with additive manufacturing for applications such as aerospace requires some very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International. Its latest proposed working standard addresses powder bed fusion AM methods for metals, which includes EOS's direct metal laser sintering (DMLS) among others. Shown here, a prototype of a topology-optimized Airbus A380 bracket made of stainless-steel powder produced via EOS's DMLS (right) with a conventional cast steel bracket shown behind.

Development of Standards

Good move by ASTM.  As rapid manufacturing continues to grow, well-defined material standards need to continue to be developed - especially for highly regulated industries like aerospace and medical.

Standards are the only way to advance. It helps most industries, it will here too.

Excellent point Greg, much better than putting the cart before the horse and then having compatibility issues later. Standards tend to evolve somewhat with new technologies but they are definitely a good idea, especially in the fields you mentioned.

 It would be nice to see printer material delivery standards.  Companies producing new printable materials can be prevented from selling them without a fee because the printer manufacturers own the patents to material delivery mechanisms for their printers.  This could be a big material development disincentive.

Nancy, good point about the way that standards tend to "evolve." The big thing that's changed after several decades is now using these processes for end production, especially in fields with rigid quality requirements. There's enough complexity involved in 3D printing/additive manufacturing--among processes, machines, materials, and the characteristics of finished parts--that advance cooperation has become necessary.

jhankwitz, thanks for the reminder about the captive & proprietary status of so many 3D printing materials. There is an open matetrials market, especially for filament fusion printers, but these are low-end desktop machines and the materials tend to not be engineering quality. As we've discussed several times on DN, an open engineering-quality materials market is highly desirable but faces several hurdles. Standards for specifying higher-quality 3D printing materials will certainly help.
