3d printing

Cards (7)

  • Revolution
    Technology caught up with imagination, e.g. things are now cheap or off-the-shelf
  • 3D printing (Additive Manufacture)

    • Computer aided manufacture (CAM)
    • Sliced into layers
    • Reconstructed a layer at a time in the printer
  • FDM Printing

    • Made from thermoplastics like PLA and PET
    • Plastics are melted and pushed through a nozzle in fine streams
    • Printer moves in XY plane until a slice is done, then 2nd axis moves down an increment and new slice is printed
  • FDM Printing Methods
    • Plastics are melted
    • Pushed through a nozzle (fine streams)
    • Printer moves in XY plane until a slice is done
    • 2nd axis moves down an increment and new slice is printed
  • FDM Printing Pros
    • Printed on relatively inexpensive pieces
    • Consumable is just the filament rolls
    • Filament rolls available from wide selection of sources
  • FDM Printing Cons
    • Lower/poorer resolution with rougher layers
    • Lower bonding force between layers
    • Easily break along layer lines
  • Resolution is based on nozzle size
