3.2.6 Feedstock

bulk raw material supplied to the additive manufacturing building process

Note 1 to entry: This includes materials used for support structures, as long as they are removed in a separate post-processing step.

Note 2 to entry: This includes ancillary material that is essential to an AM machine and consumed during the production but not part of the final part
