Helios 3DP Intro and Design Workshop

  1. 1. Intro to and Designing for 3D Printing Alex Ruaux | alex@3dpwiz.com | @molecularcode | #3dprinting
  2. 2. What is 3D printing? Alex Ruaux | alex@3dpwiz.com | @molecularcode | #3dprinting
  3. 3. Additive process
  4. 4. Types of 3D Printing Alex Ruaux | alex@3dpwiz.com | @molecularcode | #3dprinting
  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. Alex Ruaux | alex@3dpwiz.com | @molecularcode | #3dprinting
  9. 9. Photopolymerization: Digital Light Processing (DLP) Stereolithography (SLA) Liquid Materials: photopolymer resins

  11. 11. How do I Print Something? Alex Ruaux | alex@3dpwiz.com | @molecularcode | #3dprinting
  12. 12. digital file of the 3D model (.stl) software program to ‘slice’ the model software program to talk to the printer
  13. 13. But Where Do I Get The Models?
  14. 14. model your own traditional CAD (computer aided design) parametric design (writing code)
  15. 15. 2D logo openSCAD to extrude vertically MeshLab to position and merge 2 .stl files
  16. 16. 3D scanning
  17. 17. reconstruct from photos Autodesk 123D Catch

  22. 22. Considerations When Designing for 3DP Alex Ruaux | alex@3dpwiz.com | @molecularcode | #3dprinting
  23. 23. Considerations When Designing for 3DP Gravity - 45°
  24. 24. Considerations When Designing for 3DP Support Material?
  25. 25. Considerations When Designing for 3DP Objects must be closed This is not really a concern with TinkerCAD, because all the shapes you’re working with are already closed i.e. all the faces are surfaces.
  26. 26. Expanding on TinkerCAD Alex Ruaux | alex@3dpwiz.com | @molecularcode | #3dprinting
