Beskrivelse

Bondtech Upgrade Kit BMG Extruder Prusa i3 MK3S+/MK3S & MK2.5S

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.
For even more effective HotEnd cooling we recommend a fan with high pressure like Sunon’s MF40100V1-1000U-G99 or similar.

NOTICE

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 “Download STL files” option of our “Firmware & More” 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.
