Developing Workforce and Education Framework

  • Who should we teach / train?
  • What should we teach / train?
  • How should we teach / train?
  • Challenges and opportunities?

To begin to answer these, we must understand how AM fundamentally changes the manufacturing and education environments.

What do we Teach / Train?

slide-31
SLIDE 31

Additive Manufacturing as an Integrated System

slide-32
SLIDE 32

What do we Teach?

  • What we can teach effectively today:

– AM Processes – Multidisciplinary teaming

  • Topics that depend on further development:

– AM design communication – Costing and enterprise-level design decisions – AM design methodologies

32

slide-33
SLIDE 33

AM Processes

  • Essential for manufacturing professionals to

understand in the context of traditional manufacturing processes.

– Capabilities and limitations – Differentiation between various AM processes (not “Catch All”)

A Unique Bottleneck in Human History

  • Papyrus
  • Phonetic alphabet
  • Gutenberg press
  • 3-View orthographic projections
  • Tolerances
  • Geometric Dimensioning and Tolerancing
  • Digital models (still evolving)
  • Design and communication tools for AM

34

slide-35
SLIDE 35

Everything I Needed to Know about AM Design Communication … I learned from an Igloo

35

slide-36
SLIDE 36

Igloo Language

  • Layer-wise construction technique
  • Requires specialized language to describe

– English language: “snow” – Inuit language: 15 lexemes with 1000+ inflected forms to describe “snow” (several of the lexemes are important for the igloos)

  • Building the structure properly requires the right

combination of types of snow.

– Inuits use precise language to unambiguously describe – Other languages fumble around with modifiers: “new- fallen snow, hard-packed crust, sticky snow” etc.

36

slide-37
SLIDE 37

Chain of Design Communication

  • Design

– Specifications – acceptable tolerances around nominal

  • Manufacturing

– produce parts and assemblies within tolerance

  • Validation

– Based on unambiguous specifications – Based on measuring outcomes against specifications

37

slide-38
SLIDE 38

In a Different Context

38

slide-39
SLIDE 39

“Color” as a Design Parameter

  • Traditional design parameters are discrete /

quantized, seldom continuously varying.

  • Complex contours are already a challenge for

traditional design communication tools.

  • Characteristics that vary in through-body

gradients are much more difficult to specify / satisfy / verify.

39

slide-40
SLIDE 40

“Color” of Parts – 3D Gradients

Some things we can currently control:

  • Material composition
  • Micro/Macro structure

– Microstructure – Gross anisotropy (build orientation) – Local anisotropy (tool path) – E-materials (multi-material deposition patterns)

40

slide-41
SLIDE 41

How do we Specify / Verify?

  • What is the language to communicate the “color”

parameters of our parts?

  • What is our ability to measure and verify

– gradated properties – Internal geometric features

Are our designs hampered by communication? We can make designs that we can’t effectively communicate. How, therefore, do we teach it?

41

slide-42
SLIDE 42

Teaching Additive Manufacturing

  • Teaching and learning depend on effective

communication

– Present concepts – Manipulate concepts

42

slide-43
SLIDE 43

DFAM (Design for Additive)

  • Design for Manufacturing and Assembly

(DFMA) rules have evolved to be generally applied across traditional manufacturing processes.

  • AM disrupts

key assumptions.

43

slide-44
SLIDE 44

How do we Teach / Train?

slide-45
SLIDE 45

Evolving Curriculum in Parallel with Technology

  • Technology is available at all levels of

education

  • Not yet well understood or broadly adopted in

industry

  • Technology and pricing will likely change

dramatically over a short time period

45

slide-46
SLIDE 46

AM Curriculum Development and Credentials

  • AM processes developing at a faster pace than

curricular programs can keep up.

  • NAMII will support shared, current resources
  • Aligning degree, course, certificate, and

certification program content with nationally recognized consensus materials will foster broader credential recognition.

46

SLIDE 48

Challenge and Opportunity

  • 83% of US manufacturers report an overall

shortage of qualified employees

  • 59-milion K-12 Students

– Attracting just 1% more to pursue careers in STEM / manufacturing would have tremendous impacts

  • Total number of 3D printers sold worldwide

to-date numbers only in tens of thousands.

48

slide-49
SLIDE 49

Leveling the Playing Field

49

  • Anyone with an idea can be a manufacturer
  • Same technology will be used across broad ranges

demographics

slide-50
SLIDE 50

Experiential Learning

  • Empower students at all levels to create the

tools that allow them to learn

  • Open-ended, multi-disciplinary challenges
  • AM as a classroom resource to be used

whenever applicable

50

slide-51
SLIDE 51

Growing the Pie

  • Opens up opportunities for the largest

untapped populations

– Hands-on experimentation at all levels of education attracts kids who are kinesthetic learners – Low barriers to innovation and entrepreneurship – Cost of technology is approachable

SLIDE 52

Inspiring Ingenuity

52

2013 First Robotics National Championship

  • Students make what they can’t buy
  • On-site parts hospital
  • Philosophy of empowerment and

self-reliance

  • Demonstration of “cloud sourcing” -

more than 2300 parts in 2 weeks

slide-53
SLIDE 53

Empower Everyone

The best solution to any problem lies outside of your organization.

Conclusion

  • The opportunities offered by AM are revolutionary.
  • Dissemination of the technology to the many

potential users will democratize manufacturing and spur innovation.

  • Many of the biggest challenges are tied to the rapid

rate of evolution.

  • The ability to educate our students, workers, and

enterprises about this technology is best served by a thriving, dynamic, and connected community of technology experts, manufacturers, and educators.
