On 18 August 2021, the Additive Manufacturing Maintenance Operations (AMMO) working group conducted a teleconference with approximately 40 participants.  A summary follows:

 

Introduction:  Debbie Lilu (NCMS) welcomed the group, discussed administrative protocol, and provided an overview of the agenda.

 

America Makes Mx and Sustainment Advisory Group (AMMSAG) Update – Marilyn Gaska (LMCO) provided an update that included the following:

  1. The July AMMSAG meeting featured a briefing from Rose Roy of VRC Metal Systems. She provided an update on additive repair of aircraft components with cold spray for sustainment.
  2. The AMMSAG is looking for a new vice chair. If interested, let Marilyn know.
  3. On Tuesday, Aug 17, at the Aircraft Airworthiness & Sustainment Conference, the Additive Manufacturing – Materials and Process Qualification Keystone Panel took place with Michael Gorelik, Dr. Mark Benedict – AFRL RX USAF, and Dr. Brandon Ribic – America Makes, NCDMM included on the panel. The event was both live and virtual. Presentations are available if you have a password or registered.
  4. The next AMMSAG is 17 August with Additive Engineering Solutions presenting.
  5. Aug 3-4 TRX @ OSU 2021 – America Makes (Not Virtual).
  6. America Makes Announces New Rapid Innovation Call for Projects Totaling $500K in Funding – America Makes. Submissions are due by 5pm ET on Thursday, September 2, 2021.

  7. The annual America Makes Members Meeting & eXchange (MMX) will be held
    in Youngstown, Ohio on October 19-20, 2021.
  8. The submission of abstracts for the DMC has moved to 5:00 pm ET, Aug 27. The AME subpanel has well over 30 presentations. To discuss the AM abstracts submitted to the AME subpanel please contact Ben Kassel at 301 226 8873 or email at bkassel@lmi.org
  9. CTMA Technology competition is open for submissions through Friday, October 1st. NCMS will make available $100,000 in project support funding.  The overall award winner and the People’s Choice award winner will each be awarded $50,000. This funding will go toward a selected DOD demonstration activity, to the extent permitted under the existing CTMA cooperative agreement. For more information, go to: https://www.ncms.org/ctma-competition/

 

SPEE3D Overview – Bruce Colter discussed cold spray additive manufacturing which works by accelerating compressed air and metal powder which is deposited onto a substrate maneuvered by a six-axis robotic arm.  It uses TwinSEE3D “slicing” software for SPEE3D machines which provides automated part toolpath generation and automated predicted part simulation. He then discussed its use with different types of metals and described an Australian Navy case study.

JAMWG Update – Kelly Visconti (OSD-R&E) provided an overview of JAMWG actions.

  1. DoDI 5000.93 “ USE OF ADDITIVE MANUFACTURING IN THE DOD” was issued in June.
  2. Work on the AM Guidebook continues. Michael Parkyn OSD(MANTECH) is working with a steering group. The next draft is expected in the next 2-3 months.
  3. 2021 AM Workshop. The JAMWG is continuing work on three of the seven topic areas, and are developing an action plan to tie them into existing projects.
  4. August 27 will be Kelly’s last day at OSD(R&E) and the JAMWG. She has accepted a government position at the Department of Energy working on cost-cutting issues. Tracy Frost will chair the JAMWG until Kelly’s backfill arrives.

Additive Engineering Solutions – Austin Schmidt provided a presentation on Large Format Additive Manufacturing (LFAM). LFAM uses thermoplastic resin pellets combined with large material extrusion printers to create near net shape parts quickly. He discussed several LFAM tooling projects to include 250F and 350F composite cure tools and stretch-forming tools, and described ongoing DoD efforts including an SBIR with the USAF on the development of ultra-low cost ABS feedstocks for LFAM processes for use in replacing various material handling tools and equipment.

 

Next Meeting: – The next AMMO WG call is scheduled for 10:30-12:00 am (Eastern Time) on Wednesday, 6 October 2021.

 

POC for this action is Ray Langlais, LMI, rlanglais@lmi.org, (571) 633-8019

 

Q&A

SPEE3D Overview – Bruce Colter (SPEE3D)

————————–

 

Q1. Does SPEE3D provide the powder material or can user bring their own material?

A1. Either works. In 2022, we’ll have our own SPEE3D labelled powders.

 

Q2. How do the mechanical properties compare to wrought materials (i.e. your 6061 aluminum versus wrought 6061-T6)?

A2. We are between wrought and cast on finish, our cold process, and some heat process closes the gap.

 

Q3. And do the part costs you showed include the time to program the part and setup the machine?

A3. It does not include that. If you have CAD data it is loaded into the machine which takes about 5-30 minutes.

 

Q4. Is it safe to say the postprocessing labor is on par with CNC and other Additive?

A4. Yes, generally speaking, without stress relief. The majority of parts are heat treated.
