3d printing in higher education

  1. 1. 3d printing in higher education NERCOMP 2015
  2. 2. 1. Technology overview 2. Uses in education a/k/a overview and big picture
  3. 3. Ground rules for today • Please ask questions. We forbid embarrassment. • We are assuming a baseline awareness of being new to 3d printing. • Please contribute thoughts. This is a rapidly developing field! • Tweet away at #NercompPDO3
  4. 4. I. THE TECHNOLOGY Wikipedia definition: 3D printing (or additive manufacturing, AM) is any of various processes used to make a three-dimensional object. In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control.
  5. 5. I. THE TECHNOLOGY Industry definition: 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created.
  6. 6. I. THE TECHNOLOGY Several types: • Additive (layers) (also material jetting) • Powder bed fusion (“An additive manufacturing process in which thermal energy selectively fuses regions of a powder bed”) • Binder jetting (“An additive manufacturing process in which a liquid bonding agent is selectively deposited to join powder materials.”) • Sheet lamination (“An additive manufacturing process in which sheets of material are bonded to form an object”) Quotes from the ASTM International Committee F42 on Additive Manufacturing Technologies
  7. 7. I. THE TECHNOLOGY Several types: • Subtractive (block) • Selective laser sintering and melting • Stereolithography • Extrusion • Continuous liquid interface production ( gy/a14586/carbon3d-3d-printer-resin/)
  8. 8. Parts The printing materials: • Plastic • Filaments • Metals and alloys • Powders • Concrete • Photopolymer resin (stereolithography)
  9. 9. Parts More printing materials: • Paper based, Mcor IRIS, chicago-discovers-power-versatility-affordable-full-color- paper-based-3d-printing/ • Cloth (Disney: develops-printer-creates-soft-interactive-objects- fabrics/) (High fashion: 2015-3d-printed-fashion-activated-body) • Food (Sugar: (Cornell: FF09_Cohen1_0.pdf)
  10. 10. Parts Software • Controller or client program • CAD programs • 3D authoring and editing (Sketchup, Maya) • Pre-existing files (Shapeways, Sketchup 3D Warehouse, Thingiverse, (.stl) • G-code to translate file into printing (

  15. 15. Printer examples RepRap • Open source hardware • Can serve as a recycler • (http://rep
  16. 16. A growing technology • Replacement body parts, “bioprinting” (Yale: leader-3d-organ-printing-transform- transplants) • Food • LEDs (Princeton: 816/3-d-printing-bio-electronic-parts/)
  17. 17. A growing technology • Aircraft parts ( nology-32597809) • Building components • Entire buildings
  18. 18. A growing technology
  19. 19. A growing technology Challenges and issues: • Intellectual property • Economic impact (slow down trade?) • Ecological impact • Backlash (ex: guns) • New era of individual customization + creativity
  20. 20. II. 3d in higher education
  21. 21. Reasons to do 3d visualization • teaching • also research and creative work
  22. 22. Reasons to do 3d making stuff • Prototyping • Design thinking • Sheer creativity • o_KlU Save $$ in object purchasing and replacement
  23. 23. Which academic fields? • Classical studies and archaeology • History (ex: recreate-historic-buildings-3d-printers) • Creative arts (i.e., fashion, studio art, theater) • Engineering • Robotics
  24. 24. Which academic fields? • Math • Geography and geology • Life sciences, allied health fields • Media studies ("critical making") • Business (study impact; new opportunities)
  25. 25. Strategic questions • What type of institution? (research vs engineering vs CC vs LAC) • Which disciplines show interest? • Is interest aimed at research or teaching? • Will you partner with off-campus interest and/or support?
  26. 26. Campus sites • Library • Makerspace (Abilene Christian University, • 3d lab • Professor’s office
  27. 27. Campus sites • Departmental office • Multiple sites (Northeastern: e/cni-podcast-patrick-yott-on-3d- printing-services-at-northeastern- university-libraries) • Other…?
  28. 28. Operational questions • Who owns the printing ecosystem? • Do you charge users? (intra-preneurial possibility)
  29. 29. Suggestions •Outsource printing first •Print playful objects •Have objects to show
