Prusa Mini 3D Printer


3D printers create a three-dimensional object using additive manufacturing technology. The machine extrudes a plastic filament via a heated nozzle and deposits the material onto a build platform. Objects are created by laying down successive layers of material. If the printed object requires it, support structures are generated during file processing and are included in the print to help maintain accuracy.


  • Build Volume:
    Width (front-back) 7.0 in 180 mm
    Depth (left-right) 7.0 in 180 mm
    Height (up-down) 7.0 in 180 mm
  • Layer Height: 0.05 - 0.35 mm
  • Nozzle: .04 mm default
  • Filament Diameter: 1.75 mm
  • Materials: Typically PLA or PETG
  • Max travel speed: 200+ mm/s
