5. Possibilities of Metal Additive
Manufacturing
Produce net-shape components by
successive metal build-up
Offer potentially disruptive
competitive advantages
Many U.S. companies and
researchers exploring AM
Many emerging AM technologies
- Based on laser, electron beam, arc,
high-power ultrasonics, etc.
- Using powder, wire, strip, sheetNickel-alloy pressure
vessel components
6. AM – Progressive Layers
Build in layers, Stress relieve/PWHT, Machine
7. AM Processes for Metals
EBW freeform fabrication - EB(FFF)
Laser powder and wire for FFF
LAM, LENS, DMLS, from companies such as
Arcam, EOS, POM – powder and wire based
laser and EB metals AM in confined envelope
Arc processes – GTAW-HW, GMAW-P, PTA
(wire and powder) based on commercially
available equipment for FFF
VHP UAM – very high power ultrasonic AM
8. Example Metals AM Processes

EOS DMLS®
MTT SLM®

business).

13. Emerging Apps
Range of emerging applications … rapid
prototyping, low volume tooling, direct parts
manufacture, tailored materials, MMC, embedded
fibers, smart materials, sensors, cladding, armor,
thermal management
Embedded Ni Tape
0.003” Diameter NiTi
Wire (400X)
14. Potential Competitive
Advantages
Reduce material waste and energy usage
Lower cost (fewer operations, reduced inventory,
simplified supply chain)
Support lean/agile manufacturing (shorter lead
time, less hard tooling, reduce batch size)
Enable new product design features (internal
features, tailored materials, reduced parts)
Reduce time to launch new products
Produce replacement parts for legacy systems
Support environmental sustainability
15. Realities of Metal Additive
Manufacturing
Relatively few U.S. industrial applications
beyond prototyping. Some perceptions:
- Performance of AM components not sufficiently
characterized
- ROI not sufficiently understood to support business
justification
- Not sufficiently productive, cost effective, or capable of
producing part sizes and alloys needed
Multidisciplinary solutions are needed
- No one company has the capacity to address all the
needs
- Shared investment is needed to quickly close gaps
16. Additive Manufacturing…. Need
for Collaboration
Pooling of Resources
Developing from MRL 1–9 at each OEM is costly/time consuming
Network of end users, OEMs, service bureaus and academia
Need more coordinated effort…. generate a critical mass
Business Case
Cost modeling, Need mature process costs
Technical Challenges
Material property database
Process development/distortion control
Equipment OEMs
Voice of the Customer… size capacity, build times, etc.
Controls/Requirements
Design rules/guidelines for AM, F42 Committee
Low cost input materials
Cost effective NDE
Process control (real time)
17. Collaboration Needed
Wide Range of Processes Necessitates Investigating
Each Process in Detail – this is very expensive and requires
collaboration
Initial Acceptance Values Based on LAM Process Form
Lower Bound for Tensile Properties, Typical for
Fatigue Crack Initiation
Stage 2 Evaluation of Several Processes Necessary to
Fully Validate Use of LAM Values for All Approvals of
Proposed AMS 4999 Revision
Stage 2 Evaluation of 6 to 7 Processes Needed for
Certainty of Generating MMPDS Allowables
18. AM in Europe
Most metal AM capital equipment is built in
Europe by Arcam, EOS and others
Large, informal, network of users for plastics
and metals
Loughborough University, England hosts
annual AM conference, all materials and
markets
Fraunhofer Institutes have a coordinated focus
on AM in Germany
There is a concern in the US with technology
lag
19. AM Evaluation Stages
Evaluation Stages – AMS-4999 Revision
- 1 Initial Screening
- 2 Process/Source Approval
- 3 Deposition Parameter Approval
- 4 Approval on Non-Critical Flight Hardware
- 5 Approval of Critical Flight Hardware
MMPDS data generation
Non-flight Hardware Qualification stops at
Stage 4
20. The Answer: AMC
The Additive Manufacturing Consortium (AMC)
was founded to provide a U.S. AM forum
National consortium of industry, government,
and research organizations
Mission: Advance the manufacturing readiness
of metal AM technologies to benefit consortium
members

22. AMC Structure
Encompass a wide spectrum of
manufacturers
Include technology and material
suppliers
Engage a national technology
network of research partners;
“National Test-Bed Center”
Creates a non-competitive
environment for industry to share
experience and best-practices
Leverages public and private
funding sources
Distinct from university-led
centers which often focus on
education and basic-research
23. Setting AMC Priorities
Discussions with stakeholders
- Industry, universities, government
Review of past efforts
- 2009 Roadmap for Additive Manufacturing
- 2009 Air Force additive manufacturing workshop
- 2009 EWI Ultrasonic Additive Manufacturing symposium
2010 AMC Meeting Ideation: “What should be the
highest priority AMC activities?”
- 3 breakout groups; 125 ideas contributed; 64 ideas had votes;
distilled into 15 themes
AMC members ultimately identify the priorities
24. AMC Business Priorities
Sustained consortium funding
Education & supplier development
Business analysis
Additive manufacturing solutions network
Technology/IP assessments
Collaborative leadership
25. AMC Technical Priorities
