On 5 August 2020, the Additive Manufacturing Maintenance Operations (AMMO) working group conducted a teleconference with over 80 participants. A summary follows:
Introduction: Greg Kilchenstein welcomed the group and stated that the Additive Manufacturing Direct Tasking Memorandum (AM DTM) has been extended through November 2020. The intent is to have the draft AM Instruction (currently in formal coordination) completed by then. He also stated that the virtual 2020 AM Workshop was a huge success with oner 200 participants and some substantial progress achieved in all the work groups. More information on the workgroups, as well as their AM Workshop out-briefs, are available on the AMMO website at https://ammo.ncms.org/events/2020-additive-manufacturing-workshop/ .
Azul 3D – James Hendrick described how Azul3D is bridging the gap between the size or speed trade-off. Their manufacturing solution, high area rapid printing (HARP) is fast, has a limitless scale, industrially strong, and compatible with all liquid resin chemistries. He detailed an economic case study involving HARP custom mask manufacturing and another case study on medical face shields manufacturing.
MxD: Cybersecurity in Manufacturing – Frederico Sciammarella described cybersecurity awareness, some of the available tools and services, cybersecurity workforce programs, a hiring guide for cybersecurity in manufacturing, and the MxD Cybersecurity Project Plan 2020. The plan includes the categories identify, detect, respond and recover, and protect. He then discussed the challenges in AM risk assessment and provided an assessment framework/ approach.
ANSYS – David Green and Brent Stucker described some simulation solutions for additive manufacturing. These simulation capabilities include design for AM, build set-up, process simulation, material analysis, data capture and management, and validation and part qualification. They described the engineering challenges, Ansys capabilities, and example outputs for each of the capabilities.
America Makes Mx and Sustainment Advisory Group Update – Marilyn Gaska (LMCO) provided a quick update that included the following:
- The June meeting included a deep dive from Jim Regenor on how 3D printers provide optionality for the supply chain. DR. Brandon Riddick presented an update on America Makes actions to include COVID 19 matters.
- The July meeting provided a review and update on the June virtual 2020 AM Workshop which received positive feedback. Dr. Michael Vasquez provided a deep dive focused on helping organizations maximize their investment in advanced 3D printing technologies.
- Our next AMMSAG meeting is August 20 where VRC will present their cold spray road map.
- Today is day 2 of the Technical Review & Exchange (TRX) live stream. Rob Gold spoke yesterday.
- There is a project call on “AM for Hypersonics” with the concept packet due on August 28 and an open project call September 4th. There are also rapid innovation calls. You can view them and find the proposal dates and cost share on the America Makes website at https://www.americamakes.us/project-calls/.
- The America Makes Annual Membership Meeting is now a virtual event 13-14 October (The week before the USAF AM Olympics). For more information go to the following link: https://www.americamakes.us/mmx/ .
Next Meeting: – The next AMMO WG call is scheduled for 10:30-12:00 am (Eastern Time) on Wednesday, 2 September 2020.
POC for this action is Ray Langlais, LMI, email@example.com, (571) 633-8019
Azul 3D – James Hedrick
Q1. Did you reach out to Navajo nation or respond to an RFP?
A1. No. Saw a post online and reached out to them.
Q2. What is the price range?
A2. We haven’t finalized yet. Roughly within the industrial printer range…initially around $50K for a printer, decreasing as production increases.
MxD: Cybersecurity in Manufacturing – Frederico Sciammarella
Q1. Who is DMC please?
A1. Defense Manufacturing Conference. Pushed to 2021.
Q2. Does this security also include cloud applications?
A2. Currently, it does not. It is an emerging area that we plan to move into.
ANSYS – David Green / Brent Stucker
Q1. Do you use A.I. or Machine learning algorithms for simulation and failure predictions or all the analyses are based on multi-physics models?
A1. All of the tools that we offer are multi-physics with one exception – algorithms for orientation guidance. Internally, a number of things we use train on A.I.
Q2. Do you have specific plugins for different OEM’s?
A2. Yes, we do. Our architecture is most mature for laser powder beds.
Q3. Do you have any examples of how your models and simulations compare to empirical materials and failure data?
A3. We have a lot. We have a series of case data that we can provide upon request.
Q4. Any capability supporting direct write?
A4. Not explicitly in our additive portfolio. It has been used with custom user scripts. If you want to reach us direct, we can get you in touch with who does what.
Q5. What porosity type defect are you referring to?
A.5. Lack of fusion porosity is the most devastating. You want to avoid that. Others, include gas induced, etc. We do have the ability to detect excessive vapor events.
Q6. Does your topology optimization support multiple materials for metamaterials design?
A6. Yes and no. It does to a certain extent. The operator needs to have an advanced capability / expert knowledge.
