- 8. AGENDA • What is 3D-printing? • Different types • "In depth" about the most common type • Alternatives to printing location • Post-print work • Demonstration: Going from model to 3D-print
- 9. PART 1
- 10. 3D-PRINTING “If it can be imagined, it can be made”
- 12. What is 3D-printing? • Additive process • Many differerent type of technologies
- 14. EXAMPLES
- 28. 3D-PRINTING: 3 MAIN TECHNOLOGIES • Photopolymerisation: SLA, DLP, 2PP • $ 5000 + • Merging of powder layers: SLS, EBM, DMLS • $ 10000 + • Material extrusion: FDM • $ 500 +
- 30. PHOTOPOLYMERIZATION • SLA, DLP, 2PP • Liquid plastic exposed to ultraviolet light. • Light convert liquid into solid.
- 34. MERGING OF POWDER LAYERS
- 35. "Powder printing" • SLS, EBM, DMLS
- 36. Powder printing
- 41. Fusion Deposit Modeling - FDM • Cheapest, most common, and simplest • Typ. resolution: 0.1mm/Z • Repraps, Makerbots, Solidoodle+++
- 42. FDM - cheap? Solidoodle 4 - $ 599
- 43. FDM - cheap? Stratsys Fortus 250 MC - $ 54 000
- 44. FDM - How does it work?
- 45. FDM - MATERIALS • Most common: ABS and PLA • But there exists alot of other materials for FDM: nylon, “rubber”, etc.
- 46. FDM - SIZE AND SPEED • Common printer size: 20 cm^3 • Larger print - Larger challenges... • Divide and Conquer • Does it take long time?
- 47. MODELING FOR FDM
- 48. MODELING FOR FDM - OVERHANG
- 49. MODELING FOR FDM - OVERHANG
- 50. MODELING FOR FDM - OVERHANG
- 51. MODELING FOR FDM - WALL THICKNESS
- 52. MODELING FOR FDM - “FILLETS” • Not a requirement... • But can be great to handle stress • And print-direction is important for strength!
- 53. “WARP”
- 54. MODELING FOR FDM - HOLES • Usually to small after print • Drill!
- 55. MODELEING FOR FDM - ASSEMBLY • Glue • Skrew • Make mechanical threads
- 56. MODELEING FOR FDM - SOFTWARE • Solid-modeling • STL most common • But STL is a surface modeling language: Control it for errors • “Slicer”
- 57. RECAP• 3 most common types • “Liquid” - SLA • “Powder” - SLS • “Thread” - FDM • FDM - Challenges • Overhang • Warp • Wall thickness • … • Road from model to 3D-print • Usually through the file format STL • STL is a surface modeling language, but a 3D-print is solid. Interpretation errors?
- 58. PART 2
- 59. • Alternatives to printing location • Post-print work • Demonstration: Going from model to 3D-print
- 60. FROM MODEL TO REAL LIFE
- 61. FRA MODELL TIL VIRKELIGHET
- 62. FRA MODELL TIL VIRKELIGHET
- 63. FRA MODELL TIL VIRKELIGHET
- 64. FRA MODELL TIL VIRKELIGHET
- 65. ORDERING 3D-PRINTING • Exists many different suppliers • Typical easy online quoting systems based on volume • Different printers and different materials
- 66. SHAPEWAYS
- 69. POST-PRINT WORK
- 70. POST-PRINT WITH ABS - ACETONE
- 71. POST-PRINT WORK - FILLER • Less “chemical” • Fill gaps with filler • Sanding job…
- 76. POST-PRINT WORK - KNIFE AND SANDING PAPER
- 77. FAVOURITES
- 78. QUESTIONS?
- 79. DEMO!
- 80. QUIZ!
