About the kit

Our Prusa i3 Kit is the perfect printer for beginner's or pro's alike. This 3D Printer kit combines all the best Prusa i3 upgrades with our high quality products. Each part has been thought about carefully in terms of assembly, maintenance and printing, to produce an excellent 3D Printer which will exceed your requirements. Being a 3D Printer kit, this 3D Printer not only provides a superb price, but will also be a valuable learning experience, providing a great start for any aspiring maker.

Prusa i3 RAMPS 1.4

For our Prusa i3 kit we have chosen to use a Hexagon all metal hotend which is capable of printing materials up to 295°C. This is combined with an all metal Bulldog Lite direct drive extruder, for lots of power and reliability. This extruder system, and the inclusion of a heated bed, allow for a very wide range of materials to be printed, including PLA, ABS, Nylons & Composites.

A RAMPS 1.4 (RepRap Arduino Mega Pololu Shield) electronics controller is provided, and is the most popular controller used today. Interfacing with an Arduino MEGA2560, it expands the Arduino platform to provide all the necessary features for a 3D Printer. Our 3D Printer kit also includes a LCD Smart Controller, with SD Card reader, for stand alone 3D Printing.


- Hexagon all metal Hotend and Bulldog Lite extruder upto 295ºC.
- Heated Bed capable of reaching 100ºC providing warp free 3D Printing.
- LCD Panel with SD Card Reader for stand alone printing (4gb SD Card included), USB Port available.
- Opensource RAMPS 1.4 electronics expandable to dual extruder's.
- Precision ground steel smooth rods for perfect linear motion.
- Frame Brace with Z-Axis Isolators.
- X & Y-Axis Belt Tensioners.


Prusa i3 Assembly Instructions

To help you along your way, we have created a complete end to end assembly manual, with exploded view assembly diagrams and written instructions. We have done all the leg work for you, no soldering, crimping, or cleaning of plastic parts is required, all these processes are completed by us to make the assembly of our Prusa as pain free as possible. The 3D Printer comes with pre-configured and installed firmware, as well as configuration files for the slicing software. If you have any problems along the way, we are available by email or phone to help you.

We have tried to make the assembly and operation of this printer as simple as possible. However this is still a kit, so basic technical skills will be needed to complete this printer and calibrate it for the best printing results. Further to this, computer skills are a requirement, multiple pieces of software have to be installed and configured. These are needed to operate and produce G-Code files for your printer. If you have any doubts, we recommend that you read through the instruction manual beforehand to gauge what is involved.
