It's time to join the 3D printing revolution! :)

As base design to build was chosen RepRap Prusa i3 (single sheet aluminium frame):

Prusa i3

Pros:

  • Enhanced frame rigidity
  • Easy assembly
  • Reduced number of printed parts

Cons:

  • Movable bed (limits maximum print speed)
  • Single sheet frame is designed to be manufactured through the use of a specialized equipment - Laser cutter, WaterJet, or CNC Mill / Router Table
