What is 3D Printing?

  • What is 3D?
    • 2D: Drawings, paintings.
    • 3D: Sculpture, things we use.
  • What is Printing?
    • Depositing material. Paint, graphite, ink.
  • What is 3D Printing?
    • Depositing material to make a 3D object.
  • How does a 3D Printer work?
    • Selective Laser Sintering (SLS)
      • Cost: Very High
      • Tech: High-power lasers fuse any meltable material, from plastics up to metals like titanium.
      • Advantages:
        • Produce replacement parts on demand for your fighter jet on an aircraft carrier.
        • Fused material might be recyclable.
      • Disadvantages:
        • See Cost.

Design an Object

Introducing Google SketchUp

Basic Shapes

  • Creating shapes
  • Creating rulers for precision
  • Snap to lines, shapes, rulers.

Useful Operations

  • 2D to 3D
    • Extrude: the Pull operation.
  • 3D Text
  • 3D Boolean Operations

Troubleshooting

  • When is a mesh not solid?
  • Tricks to fixing meshes so they're solid.

Exporting

Other Resources

MeshLab Manipulations

  • Useful for:
    • Checking models for manifoldness
    • Basic fixing operations
    • Basic scaling operations

NetFabb Tools

Useful for semi-automated and fully automated repair of meshes, particularly for submission of data to fabrication services such as Shapeways and Ponoko.

Slicing Fabjects

ReplicatorG

  • Basic STL positioning and scaling operations.
  • Hooks into Skeinforge (included).
    • Turn on skeinview
  • Read the resulting GCode.

GCode Visualization (Optional)

Printing to MakerBot Machines

  • Print Direct
    • Cupcake: Only print direct for simple designs. The serial link bogs down too easily when there are lots of small movements as found in curves and circles.
    • Thing-O-Matic: No issues printing directly.
  • Print Buffering to SD Card
    • Cupcake: Preferred over direct printing. Necessary for stand-alone operation.
    • Thing-O-Matic: Optional. Necessary for stand-alone operation.
  • Print to File (aka SD Card in USB reader)
    • Cupcake: Faster than dumping data over serial link. Useful for preparing files for multiple "identical" machines.
    • Thing-O-Matic: Faster than dumping data over serial link. Useful for preparing files for multiple "identical" machines.
