The Prusa i3 (iteration 3) is the newest and current 3D Printer design by RepRap core developer Prusajr (Josef Prusa). The Prusa i3a is a derivative/fork that includes both adjustable bed leveling and many reinforced/improved parts.

Specifications

  • Printed Parts: 35
  • Printing Size: 9" x 9" x 6.5"
  • Precision: 50 Micron Z Resolution

Main Improvements

(main improvements made upon Josef Prusa's Prusa Mendel Iteration 3

  • Frame Stabilizers
  • Easy Assembly
  • Print friendly parts with minimal cleanup

Where to get it

Kits are not sold anymore by DIY Tech Shop, nor are assembled printers. While you could self-source your own, don't -- just build a Prusa i3 or an i3 Rework or any other printer design.

Printed Parts

The STL files to make the printer can be found at:


Stepper Motors

The Prusa i3a uses (including the Extruder), Five NEMA17 Stepper Motors:

  • Two of these Motors (the Z-Axis motors), are connected to the same Stepper Driver of the Electronics
  • If using Wade's Geared Extruder, it's Stepper Motor needs a minimum Holding Torque of 40Ncm (0.4Nm)

More information can be found on the Stepper Motor page.

Controller Electronics

Just about any RepRap Controller will work for the Prusa i3xl.

Requirements:

  • Four Stepper Drivers
  • One Thermistor Input and one Heater Output for the Extruder

For comparisons, see List of electronics, Comparison of Electronics and Alternative Electronics.

Extruder

For the Prusa i3x

It's a Greg's-Wade's extruder with toothed gears and a pre-formed slot for a groove/JHead hotend. The extruder parts available from the Prusa i3 repository are mostly compatible.

Compatible hotends:

DIY Tech Shop Crayon tip hotend -- They don't make this one either anymore.

E3d hotend

Budaschnozzle

  • Note: The Budaschnozzle doesn't mate very well with the Gregs-Wade's extruder body.

All Jhead compatible hotends...
