Intro to 3D Printing - Google Montreal Tech Series

  1. 1. Intro to 3D Printing ... there’s more to it than yoda heads and plastic frogs! Alex Ruaux | alex@alexruaux.com | @molecularcode | #3dprinting
  2. 2. What is 3D printing? 1/7
  3. 3. Additive process
  4. 4. Types of 3D Printing 2/7
  5. 5. 3 main types: Extrusion Deposition Granular materials binding Polymerization by light
  6. 6. Extrusion Deposition: FDM - Fused Deposition Modeling FFF - Fused Filament Fabrication Solid Materials: themoplastics, rubbers, clay, silicone
  7. 7. Granular Materials Binding: Selective Laser Sintering (SLS) Direct Metal Laser Sintering (DMLS) Powdered Materials: metals, thermoplastics, ceramics
  8. 8. Photopolymerization: Digital Light Processing (DLP) Stereolithography (SLA) Liquid Materials: photopolymer resins
  9. 9. Form 1 printer
  10. 10. How do I Print Something? 3/7
  11. 11. digital file of the 3D model (.stl) software program to ‘slice’ the model software program to talk to the printer
  12. 12. But Where Do I Get The Models? 4/7
  13. 13. model your own traditional CAD (computer aided design) parametric design (writing code)
  14. 14. 2D logo openSCAD to extrude vertically MeshLab to position and merge 2 .stl files
  15. 15. 3D scanning
  16. 16. reconstruct from photos Autodesk 123D Catch
  17. 17. online repository www.thingiverse.com
  18. 18. gcode ;Sliced D:DownloadsButton.stl at: Fri 16 Nov 2012 22:22:17 ;Basic settings: Layer height: 0.2 Walls: 1 Fill: 70 ;Print time: 0:12 ;Filament used: 0.67m 5.75g ;Filament cost: Unknown G21 ;metric values G90 ;absolute positioning M107 ;start with the fan off G28 X0 Y0 ;move X/Y to min endstops G28 Z0 ;move Z to min endstops G92 X0 Y0 Z0 E0 ;reset software position to front/left/z=0.0 G92 E0 ;zero the extruded length G92 E0 ;zero the extruded length again ;G1 X100 Y100 F9000 G1 F9000 ;LAYER:0 ;TYPE:SKIRT G1 X74.484 Y100.0 Z0.2 F9000.0 G1 X75.028 Y105.148 Z0.2 F1200.0 E2.0789 G1 X76.424 Y109.749 E2.1522 G1 X78.784 Y114.171 E2.2286
  19. 19. Personal and Desktop Manufacturing 5/7
  20. 20. Instant-Gratification
  21. 21. Customization
  22. 22. Rapid-Prototyping
  23. 23. And it’s just plain FUN!
  24. 24. model asteroids and satellites as part of a display

  26. 26. the framework and outer structure of robots
  27. 27. life-sized animatronic ~600hrs of printing so far
  28. 28. What is Being 3D Printed Today? 6/7
  29. 29. medicine
  30. 30. weapons
  31. 31. environment
  32. 32. fashion
  33. 33. Urbee 2 transport
  34. 34. future engineering
  35. 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. 36. Is 3D Printing OverHyped? Will It Become Mainstream? 7/7
  37. 37. Better Design Programs
