Possibilities of Metal Additive Manufacturing
Produce net-shape components by successive metal build-upOffer potentially disruptive competitive advantagesMany U.S. companies and researchers exploring AMMany emerging AM technologies- Based on laser, electron beam, arc,
high-power ultrasonics, etc.- Using powder, wire, strip, sheetNickel-alloy pressure
vessel components
AM – Progressive Layers
Build in layers, Stress relieve/PWHT, Machine
AM Processes for Metals
EBW freeform fabrication - EB(FFF)Laser powder and wire for FFFLAM, 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 FFFVHP UAM – very high power ultrasonic AM
Example Metals AM Processes
Concept Laser DCM®
EOS DMLS®
MTT SLM®

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)
Potential Competitive Advantages
Reduce material waste and energy usageLower 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 productsProduce replacement parts for legacy systemsSupport environmental sustainability
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
Additive Manufacturing…. Need for Collaboration
Pooling of Resources Developing from MRL 1–9 at each OEM is costly/time consumingNetwork 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 databaseProcess 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)
Collaboration NeededWide Range of Processes Necessitates InvestigatingEach Process in Detail – this is very expensive and requires
collaboration
Initial Acceptance Values Based on LAM Process FormLower Bound for Tensile Properties, Typical forFatigue Crack Initiation
Stage 2 Evaluation of Several Processes Necessary toFully Validate Use of LAM Values for All Approvals ofProposed AMS 4999 Revision
Stage 2 Evaluation of 6 to 7 Processes Needed forCertainty of Generating MMPDS Allowables
AM in Europe
Most metal AM capital equipment is built in Europe by Arcam, EOS and othersLarge, informal, network of users for plastics and metalsLoughborough University, England hosts annual AM conference, all materials and marketsFraunhofer Institutes have a coordinated focus on AM in GermanyThere is a concern in the US with technology lag
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 generationNon-flight Hardware Qualification stops at Stage 4
The Answer: AMC
The Additive Manufacturing Consortium (AMC) was founded to provide a U.S. AM forumNational consortium of industry, government, and research organizationsMission: Advance the manufacturing readiness of metal AM technologies to benefit consortium members

Advancing Manufacturing Readiness
AMC StructureEncompass a wide spectrum of manufacturersInclude technology and material suppliersEngage a national technology network of research partners; “National Test-Bed Center” Creates a non-competitive environment for industry to share experience and best-practicesLeverages public and private funding sourcesDistinct from university-led centers which often focus on education and basic-research
Setting AMC PrioritiesDiscussions 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
AMC Business Priorities

Proposed 1st year goals & deliverablesObtain broad industry & government support Conduct state-of-the-art review of metal AM technologyEstablish a database for collecting metal AM property informationOrganize “National Test Bed Center” research partners networkIdentify technology priorities and create development plan
AMC Member StructureMember types- Full members: Major manufacturers / end-users- Supplier member: Equipment/material suppliers:- Associate member: SME component suppliers- Research partners: Universities/labs (by invitation only)- Government: Partnering agencies
Seeking members to identify 1st year priorities- All members and research partners attend AMC
meetings and receive research results- Full members and partnering agencies eligible to serve
on AMC Industrial Advisory Board
BenefitsMembers identify AMC prioritiesMembers receive results regularly; 2 year moratorium on public release Programs engage a broad range of technical resources Continuity allows long-term planning to advance AM manufacturing readinessCollaboration with industry and government facilitates acceptance and commercializationAMC provides program management to oversee projects and deliver results
BenefitsFunding leveraged with other members, government programs, and other EWI programs Full members and associate members receive a worldwide, non-exclusive license to use IP from member-funded programsSupplier members receive first opportunity to commercialize developmentsResearch partners have access to funding opportunitiesRegular update meetings allow members to interact with colleagues and review activities
AMC Differentiation
National center - through collaboration with other centers and programsAMS 4999 and MMPDS configured data and data sharing – National standards and data for aerospace and other designersConsortium uses equipment and human resources at existng centers – no need to replicate activity – this is happening nowFunding from government agencies as well as congressional requests – all data available to all AMC members
AMC Differentiation
