Prusa Mendel i2 Reprap 3DPrinter DIY Kit+ 1730 Full Metal Hotend

The Prusa Mendel i2 Reprap 3D Printer is arguably the most widespread Reprap open-source 3D Printer to date. The Prusa Mendel i2 has made history and brought 3D printing to the attention of thousands of makers worldwide. It now comes with the exciting and extremely powerful new 1730 Full Metal Hotend! Don't waste your time with a cheap China 3D-Printer Kit (that will give you tons of issues and NO support) but go for the proven quality of ReprapUniverse.

Great for beginners

If you are new to 3D Printing, the Prusa Mendel i2 is a perfect model to start your 3D printing adventure. The mechanical structure of this 3D printer is set to be easy to build and gives you great amount of flexibility for future enhancements.

Future proof 3D printer

The Prusa Mendel i2 is a Reprap open-source 3D printer that really brings to life the true beauty and value of the Reprap movement. As the 3D printing industry is evolving at an ever increasing pace, the Prusa Mendel i2 gives you the flexibility to anticipate on these developments as literally every single part is replaceable. When a new great HotEnd comes along, you can simply upgrade your machine instead of buying a whole new 3D printer. Furthermore the printer can reproduce its own plastic parts. We recommend printing a set of spare parts once you have the printer operational. The STL files can be viewed and downloaded here.

Quality components & service

ReprapUniverse has carefully selected the components that form part of this Kit. All Prusa Mendel i2 printed parts where printed on low speeds on our machines to guarantee the highest possible quality of these parts. If a part breaks during the assembly of the printer we are happy to send you a free replacement part. We have added some parts that have a beneficial impact on the overall printing quality of the Prusa Mendel i2 3D Printer like Aluminium Z Motor Couplers and a Trespa Y Carriage Plate.

1730 Full Metal Hotend - Print 1.75 & 3 mm Filament in superior quality

The 1730 Full Metal Hotend is a brand-new Hotend that sets the standard within the Reprap 3D printing industry. With this innovative, modular Full Metal Hotend it is now possible to switch from printing 1.75 mm to 3 mm Filament by simply changing the Filament Nozzle Unit in just a few minutes. 1730's innovative modular design is leakage proof and highly optimized for printing standard filaments, special filaments and high-temperature filaments. With the 1730 Full Metal Hotend you can print almost everything in the best possible quality. Bad prints just belong to the past or to your colleague with that cheap China Hotend :-)!

3D Printer Controller - RAMPS 1.4

RAMPS 1.4 interfaces with an Arduino compatible Mega 2560 board and and has an extra slot for a 5th stepper motor driver. If you intend on upgrading your machine with an extra extruder in the future you should opt for the RAMPS 1.4 3D printer controller.

Stepper Motor Drivers - A4988

The A4988 Stepper Motor Drivers are a complete microstepping motor driver solution with built-in translators for easy operation. The stepper motor drivers are designed to drive bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A4988 stepper motor drivers include a fixed off-time current regulator which can operate in slow or mixed decay modes.

Display Upgrade

It is possible to upgrade your full kit with a LCD Display Controller for standalone printing (printing without a pc connected). We highly recommend operating the printer with an LCD Display Controller as your pc can have a negatively influence on the print job. The Display Controller has a SD card reader & fan control. The case for the LCD display can be printed from Thingiverse.

Fan Upgrade

You can upgrade your Prusa Mendel i2 - Full DIY Kit with a fan and mount that is attached directly to the extruder. This fan is highly recommended, especially for printing PLA, as it will cool the extruded filament. The fan will improve bridging and overhang performance. Adding a fan also means that you don't need to insert a minimum layer time in your slicing profile.
