* ASTM International Conference on Additive Manufacturing (ICAM 2024 – 28 October 2024 to
1 November 2024 in Atlanta, GA ) - https://amcoe.org/event/icam2024/
-- Alan Sukert chairperson of the IEEE-ISTO PWG Imaging Device Security(IDS) Workgroup
participated in the Industry 4.0: Security Aspects of AM track within the ICAM 2023
conference. The title of his presentation was "Developing Cyber Security Certification for
the Additive Manufacturing Process"
-- 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 digital
thread workflow. The new capabilities can be used to validate some of the latest Additive
Manufacturing Security efforts being undertaken by NIST.
-- The conference organizers have now extended an invitation to Alan to participate as an
invited speaker at the upcoming ICAM 2024
-- The PWG also has a potential opportunity to possibly co-present with one of the Industry 4.0:
Security Aspects of AM track sponsors on how the Cybersecurity aspects of IPP can be utilized
in conjunction with IPP 3D semantics to provide improved Cloud to production class 3D Printing
equipment Cybersecurity controls using relatively insecure Internet based infrastructure to
make the physical network connection.
* Opportunities to Promote PWG 3D Related Standardization Efforts that were not pursued
-- Drupa Next Age
--- https://www.drupa.com/en/Media_News/Press/Press_Material/Press_releases/
drupa_next_age_Platform_for_networking_and_new_business
--- The PWG was offered a presentation slot from 12:30 to 1:15 pm on 6 June 2024. After reviewing
the benefits to the PWG of promoting its 3D related printing standards work at Drupa via a
panel presentation, to the logistics and costs associated with getting Paul Tykodi from New
Hampshire to Dusseldorf on relatively short notice, the PWG Steering Committee decided not to
pursue the Drupa DNA opportunity.
-- TCT 3Sixty Conference
--- https://tct3sixty.com/
--- The PWG December 2023 abstract submission (Construction & Architecture - Safe G-Code for
sharing test files) did not result in an offer to make a presentation.
* America Makes & ANSI Additive Manufacturing Standardization Collaborative (AMSC)
-- https://www.ansi.org/standards-coordination/collaboratives-activities/additive-
manufacturingcollaborative
--- The IEEE-ISTO Printer Working Group participated in the AMSC version 3 update activities.
ANSI announced publication of version 3 on 17 July 2023.
--- The sponsor of the AMSC effort (America Makes) has recently established two new Digital
Stockpile working groups. Due to the past participation of the PWG in AMSC activities, it
received notification of the establishment of Working Group 2 titled "Digital Infrastructure,
Data Packages, Standards, and IP Protections". Paul Tykodi has subscribed to the working
group mailing list to monitor the standardization efforts discussed in the working group on
behalf of the PWG.
--- At the May 2023 PWG F2F, some editorial improvements impacting PWG content in the AMSC
version 2 document were approved in the PWG Session titled "3D Printing Liaisons - Status &
Guidance". Some of the PWG approved editorial changes did make it into the AMSC version 3
update published in July 2023, while others did not.
--- ANSI has announced that they will be accepting updated content for AMSC version 3 in the fall
of 2024. Paul Tykodi plans to add the remaining approved by the PWG AMSC editorial
improvement text from calendar 2023 to the AMSC version 3 document when the fall updating
opportunity becomes available.
