  • 1. 
    What is an STL?

  • The initial pre-sliced file.
  • The final sliced file.
  • A type of filament.
  • The coding program.

  • 2. 
    What is infill?

  • Extra material printed inside to avoid collapse. We usually print at 20%.
  • The designed object is turned into layers.
  • Extra material printed on the outside of the object to support overhangs.
  • The filament is cut.

  • 3. 
    What happens during slicing?

  • The filament is cut.
  • The designed object is turned into layers.
  • Extra material is printed inside the object.
  • Extra material is printed outside to support overhangs.

  • 4.

  • 5. 
    What is a nozzle?

  • It is the part of the printer that melts the filament.
  • It is the part of the printer that pushes the filament down.
  • It is the part of the printer that holds the 3D object as it prints. It is heated to a lower temperature.

  • 6. 
    What are the basic characteristics of 3D Printing?

  • 3D objects are made in layers, it is an additive process
  • 3D objects are created using a subtractive process
  • 3D objects print from the computer
  • 3D objects are downloaded and printed from the internet

  • 7.
