Ask AI about this product

A lightweight high-resolution extruder upgrade for the popular Prusa I3 MK3S 3D printers, featuring an optimized design achieved with the help of the community.

This upgrade kit is compatible only with the original All Metal V6 hotend that is supplied with each Prusa.

Upgrade Your Extruder

Upgrade your extruder to a Bondtech Mini Geared with higher gear ratio – 3:1 – that allows for extra push force and higher resolution.

Print Faster Or With Higher Quality

Use a lightweight extruder that will allow your 3D printer to print faster or to achieve better surface quality.

Reduce 3D Printing Issues

Decrease the risk of heat creep to avoid clogs and improve filament feeding to avoid slipping and deformation that cause under and over extrusion issues.

This Upgrade Kit does not include the gears (already supplied by Prusa).
This Upgrade Kit requires extra parts to install (X-Carriage Kit).
You can buy the x-carriage for the MK3S from us or you can download the free STLs models and 3D print the x-carriage parts available also for the Prusa i3 MK2.5. Use the ā€œDownload STL filesā€ option of our ā€œFirmware & Moreā€ menu to reach the download links.

Working Temperature Limits

Bear in mind that if you use this upgrade kit inside a closed chamber, it will have the following set of working temperature limits:

  • Due to the sensor plastic parts made of HT PLA > up to 60°C (90-100°C when parts are annealed);
  • Due to the stepper motor > up to 80°C.

Upgrade kit With Optimized Design

This is the latest generation Bondtech upgrade for the popular Prusa I3 MK3S, with an optimized design achieved with the help of the community.

Bondtech Extruder For Prusa i3 MK2.5S & MK3S & MK3S+

This kit contains only the necessary parts to convert your current extruder to our own popular design based upon our BMG (Bondtech Mini Geared) extruder with 3:1 gearing ratio for better precision and resolution together with optimized geometry for the heatsink cooling and professional SLS 3D printed housing.
It is also compatible with the MK2.5S model.

Lightweight BMG (Bondtech Mini Geared)

With this version we also lower the moving weight to reduce ghosting and vibrations or to allow increasing the printing speed. 15% of weight saving was achieved.

Product Main Features

This extruder upgrade kit is for the Prusa i3 MK2.5S / MK3S / MK3S+.
These are its main features:

  • Adapted to fit Prusa’s new filament sensor;
  • Includes one Bondtech’s BMG extruder with 3:1 gearing ratio;
  • Optimized geometry for heat-sink cooling;
  • Less moving weight to reduce vibration and ghosting;
  • Professional SLS 3D printed housing.
Addressing 3D printing Issues

The enhanced housing design improves cooling and decreases heat creeping issues that all metal hotends have when printing with PLA. This small enhancement will avoid many clogs.
The increased push force will drastically reduce slipping, shredding and deformation of the filament avoiding most of the common filament 3D printing issues that start with under and over extrusion.


Updating the Firmware

To use this upgrade in the MK2.5S / MK3S / MK3S+, the E-steps and Z_Max needs to be updated. Check out the latest version of our firmware here.

Ā 

Is this upgrade compatible with my Prusa printer models?
Yes, it is designed for the MK2.5S, MK3S and MK3S+ and requires the original All Metal V6 hotend supplied with Prusa.
What parts are included and what else do I need to install?
The kit includes one Bondtech BMG extruder with 3:1 gearing and a optimized housing. It does not include the gears, which are supplied by Prusa, and it requires an X Carriage Kit to install.
Will the upgrade improve print speed or quality?
Yes. The lighter extruder reduces moving weight by about 15 percent and the 3:1 gearing provides higher push force, while improved cooling helps reduce heat creep for better quality.
What are the temperature limits when using this upgrade in a closed chamber?
If used inside a closed chamber, sensor parts made of HT PLA can up to 60C, up to 90 100C when annealed, and the stepper motor up to 80C.
Do I need to update firmware for this upgrade and how?
Yes, updating the firmware is required to adjust the E steps and Z max. See the Firmware and More menu for the latest firmware and instructions.
