Transcript

  • 1. Intro to 3D Printing ... there’s more to it than yoda heads and plastic frogs! Alex Ruaux | alex@alexruaux.com | @molecularcode | #3dprinting
  • 2. What is 3D printing? 1/7
  • 3. Additive process
  • 4. Types of 3D Printing 2/7
  • 5. 3 main types: Extrusion Deposition Granular materials binding Polymerization by light
  • 6. Extrusion Deposition: FDM - Fused Deposition Modeling FFF - Fused Filament Fabrication Solid Materials: themoplastics, rubbers, clay, silicone
  • 7. Granular Materials Binding: Selective Laser Sintering (SLS) Direct Metal Laser Sintering (DMLS) Powdered Materials: metals, thermoplastics, ceramics
  • 8. Photopolymerization: Digital Light Processing (DLP) Stereolithography (SLA) Liquid Materials: photopolymer resins
  • 9. Form 1 printer
  • 10. How do I Print Something? 3/7
  • 11. digital file of the 3D model (.stl) software program to ‘slice’ the model software program to talk to the printer
  • 12. But Where Do I Get The Models? 4/7
  • 13. model your own traditional CAD (computer aided design) parametric design (writing code)
  • 14. 2D logo openSCAD to extrude vertically MeshLab to position and merge 2 .stl files
  • 15. 3D scanning
  • 16. reconstruct from photos Autodesk 123D Catch
  • 17. online repository www.thingiverse.com

  • 19. Personal and Desktop Manufacturing 5/7
  • 20. Instant-Gratification
  • 21. Customization
  • 22. Rapid-Prototyping
  • 23. And it’s just plain FUN!
  • 24. model asteroids and satellites as part of a display
  • 25. cases for the electronics of air quality testers
  • 26. the framework and outer structure of robots
  • 27. life-sized animatronic ~600hrs of printing so far
  • 28. What is Being 3D Printed Today? 6/7
  • 29. medicine
  • 30. weapons
  • 31. environment
  • 32. fashion
  • 33. Urbee 2 transport
  • 34. future engineering
  • 35. “As an additive, rather than subtractive, process, it uses less material and is therefore lighter and cheaper.” “Enables the design and production of previously difficult of impossible structures.”
  • 36. Is 3D Printing OverHyped? Will It Become Mainstream? 7/7
  • 37. Better Design Programs
  • 38. Lower Cost
  • 39. Ease of Use
  • 40. Lower the minimum knowledge and effort required.
  • 41. Montreal 3D Printing Dec, 6.30pm Thursday 12 th Atelier des Ingénieux 7240 rue Clark, #201 and every 2nd Thursday at varying locations www.meetup.com/Impression-3D-Montreal-3D-Printing Alex Ruaux | alex@alexruaux.com | @molecularcode | #3dprinting
