MendelMax 1.5 Reprap 3D Printer Full Kit+ 1730 Full Metal Hotend

The MendelMax 1.5 Reprap 3D printer is a cutting-edge affordable Reprap 3D printer suitable for heavy-duty 3D printer usage (10+ hours / day). MendelMax 1.5 3D printers are typically found in FabLab and 3D production environments. 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.  

High performance 3D printer

The MendelMax 1.5 is specifically designed for high performance Reprap 3D printing demands. Its thick aluminum extrusions (profiles) create a great stability on the Axis which has extremely positive effects on the smooth operation of the printer. The rigid frame construction of the MendelMax 1.5 allows the 3D printer to run at higher speeds without loosing too much on the overall printing quality. 

Design improvements

The great initial design of the MendelMax 1.5 has been improved by us on some vital key areas to even further increase the overall performance and printing quality. We have switched the multiple plated sandwich y-carriage construction for a lightweight, single Trespa (HPL) y-carriage plate. Trespa is a better material of choice for the y-carriage than the heavier aluminium as the carriage creates less resistance. The printed z motor coupler parts were changed by machined aluminum z motor couplers which give a preciser transition of the motors to the z axis of your MendelMax 1.5 3D printer.

Future proof 3D printer

The MendelMax 1.5 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 MendelMax 1.5 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. 

Quality components & service

ReprapUniverse has carefully selected the components that form part of this Kit. All MendelMax 1.5 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 MendelMax 1.5 Printer like Aluminium Z Motor Couplers and a Trespa Y Carriage Plate. 

Every Piece Matters - 0.25 mm ABS MendelMax 1.5 Printed Parts

The Printed Parts that form the heart of the MendelMax 1.5 3D Printer comprise all the latest advancements of the MendelMax 1.5. All Parts are printed in ABS which make them very durable, resistant and suitable for heavy duty usage. The Printed Parts have a layer height of 0.25 mm and were printed on low speeds to guarantee the highest possible quality.

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

he 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 Printing Powerhouse - RAMPS 1.4 3D Printer Controller

The RAMPS 1.4 3D Printer Controller is a complete electronics solution for driving your MendelMax 1.5 Reprap 3D Printer. The RAMPS 1.4 3D Printer Controller Board interfaces with an Arduino compatible Mega 2560 board and has an extra slot for a 5th stepper motor driver which gives you the option of upgrading your machine with an extra extruder in the future. The board comes with the feature-rich Marlin firmware, four A4988 stepper motor drivers. it is possible to upgrade this Kit with a Display solution for true standalone printing (no computer connected). Please contact us for more information on the Display.

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 MendelMax 1.5 - 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.
