Questions and Answers

What is the main difference between Fused Deposition Modelling (FDM) and StereoLithoGraphy (SLA) 3D printing processes?

  • FDM builds up layers of melted plastic materials while SLA does not involve layering plastic materials. (correct)
  • FDM printers require slicing the 3D model into layers using a Slicer Software while SLA printers do not.
  • SLA printers use resin while FDM printers use filament.
  • SLA printers cool the model down to one solid piece, while FDM printers do not.
  • Which type of material is commonly used in Fused Deposition Modelling (FDM) 3D printing?

  • Rubber
  • Plastics (correct)
  • Sandstone
  • Metals
  • In Fused Deposition Modelling (FDM) 3D printing, what must be done to the 3D generated model before printing?

  • Cool it down to a solid piece
  • Move the components in all three axes
  • Create it in one whole process
  • Slice it into layers using a Slicer Software (correct)
  • What type of material does StereoLithoGraphy (SLA) 3D printing commonly use?
