* American Concrete Institute Committee 564 - 3-D Printing with Cementitious Materials
-- https://www.concrete.org/committees/directoryofcommittees/
acommitteehome.aspx?committee_code=C0056400
--- On Monday 30 October 2023, Paul Tykodi attended the ACI Committee 564 meeting at the ACI
Fall Conference in Boston, MA. The purpose was to investigate whether it might be possible
for the IEEE-ISTO Printer Working Group to make a presentation on its Safe G-Code best
practice document to ACI 564 members via an ACI Training Webinar.
--- Answer from ACI Committee 564 was that he should update the PWG presentation slides from
fall 2019, to clearly focus on the use case that Safe G-Code supports, and the committee
would then decide whether to accept the proposal or not. If the committee agrees a webinar
seems useful, it will decide whether to sponsor the webinar itself or not.

--- Alan's presentation leveraged some new capabilities recently added to the Common Criteria
standard, which can be used to develop Common Criteria certification for a whole 3D Digital
Thread workflow. The new capabilities can be used to validate some of the latest Additive
Manufacturing Security efforts being undertaken by US NIST.
