AMMO Monthly Meeting

AMMO WG Teleconference Minutes – 1 May 2019


On 1 May 2019, the Additive Manufacturing Maintenance Operations (AMMO) working group conducted a teleconference with over 45 participants.  A summary follows:


Update upcoming AM Workshop 18 – 19 June, Lockheed Martin Global Vision Center – Greg Kilchenstein (OSD-MR) stated that this workshop is a bit different than the two AM Business Model Wargames and last year’s AM Workshop in that the AMMO WG partnered up with the JAMWG to align the working groups with the America Makes Councils.


The Workshop will have five Work Groups with the below subgroups:

Data Standards and Data / Model Sharing Work Group (Dennis Butcher / LCDR Pat Veith)

  • JAMMEX (America Makes Project) (John Wilcynzski / Joe Fagan)
  • TDP Standard Project Sub-Group (John Schmelzle / Tony Delgado)
  • Cybersecurity Challenges and Solutions (Blockchain Experience) Sub-Group (Jim Regenor / Dana Ellis)

Qualification and Certification Work Group (Jennifer Wolk / Jeff Gaddes)

  • Database & Common Language Sub-Group (Dr. Yan Lu / Jennifer Wolk / Peter Coutts)
  • Standards Sub-Group (Matt Borsinger / Jim McCabe)
  • Quality Assurance / Post Processing Sub-Group (Mark Benedict / David Busby / Ron Edmunds / Teresa Clement)

Business Practices Work Group (Greg Kilchenstein / Marilyn Gaska)

  • AM Contracting Guide Sub-Grp (Tim Koeppel/Bob Appleton/Debbie Lilu/John Ballou)
  • AM Integration into Supply Chain Sub-Group (Andrew Meighan / Ben Thompson / Col Brian Copes)
  • IP Management Sub-Group (Mike Acosta / Tim Slabouz / Howie Marotto)

Workforce Development Working Group (Michael Britt-Crane / Jim Davis)

  • AM technician training and certification for the conventional supply chain as well as forward deployed and tactical applications.
  • DoD engineering education and training requirements (conventional supply chain focus)
  • DoD acquisition professional education and training requirements

DoD AM Policy Development Working Group (Greg Kilchenstein / Steve Linder)

Brief Overview M1 Abrams AM Project – Tony Delgado (DLA) discussed a project between the Marine Corps Systems Command, John Hopkins University, and SPAWAR to AM print an M1 impeller. The impeller, which is a rotational metal part, was originally manufactured through casting and has a long lead-time from a sole source. The objective was to test the procurement system and track costs throughout the process. The impeller was reverse engineered and a 3D PDF format TDP was developed that includes 3D drawings, manufacturing data, CAD files, feasibility data, and performance results. Twelve impellers were successfully manufactured and tested. The next steps are data storage configuration and part number / serial number tracking.

Supply Chain Modernization – Unmanned Arial System Dave Cooper (Anglicotech) described the “Pacific Blitz” objectives and scheme of maneuver. The objectives include processing service requests in a field environment using existing Log IT systems; producing parts from that request using organic MLG AM capability under field conditions; demonstrating integrated sUAS Capability in providing rapid, responsive, and flexible sustainment options in support of dispersed and semi-independent operations; and documenting DOTMLPF components required to support the scenario.

Next Meeting: – The next AMMO WG call is scheduled for 10:30-12:00 am (Eastern Time) on Wednesday, 5 June March 2019.

America Makes Maintenance and Sustainment Advisory Group Update – Marilyn Gaska (Lockheed Martin)



Brief Overview M1 Abrams AM Project – Tony Delgado (DLA)

Q1. How much post-processing of the steel 316 L is required?

A1. I don’t believe there is much, if any, other than the support structure.


Q2. Is a next step exercising procurement?

A2. We are going to give it a shot here…do a round robin.


Q3. How many impellors were made?

A3. I think there were 12.


Q4. Do you have IP concerns going forward?

A4. No, this was a total reverse engineering effort. No GE Designs were used. The lawyers involved ensured us that there was no infringement of IP.
