The Bondtech Upgrade Kit for Prusa i3 MK3S is a lightweight high-resolution extruder dedicated to improving performance and reliability of this iconic Prusa 3D printer model. Its optimized design was achieved with the help of the Prusa community.
Upgrade Your Extruder
Increase the gear ratio of your extruder to a 3:1 that will deliver extra push force and higher resolution.
Print Faster Or Better
With this lightweight extruder that saves 15% of the weight of the parts replaced, it is possible to 3D print faster or to improve the surface quality when printing at the same speed.
Reduce 3D Printing Issues
Improving material extrusion will decrease the risks of encountering 3D printing issues. Avoid heat creep and reduce clogs. Get a regular and precise material feeding with no slipping neither filament deformation to minor under and over extrusion caused issues.
Upgrade kit With Optimized Design
The Bondtech for Prusa i3 MK3S is the latest upgrade kit from the Swedish manufacturer that incorporates all improvements achieved with the help of the Prusa community.
Bondtech Extruder For Prusa i3 MK3S
This kit contains all the parts needed to convert your printer's extruder to the popular Bondtech BMG (Bondtech Mini Geared) based design. Its 3:1 ratio increases the accuracy and resolution of material extrusion. Its carriage printed with PA12 by the SLS process and with updated geometry optimizes the hotend’s heatsink cooling.
Lightweight BMG (Bondtech Mini Geared)
This upgrade saves 15% weight of the extruder. This reduction will have meaningful impact on the moving weight and vibration thus lowering the ghosting effects.
Product Main Features
What’s in the Box
Reducing 3D printing Issues
The new housing design improves the heatsink cooling and lowers heat creep issues that are associated when all metal hotends print with PLA. This enhancement is meant to avoid PLA clogs.
The higher push force drastically reduces slipping, shredding and filament deformation and works to avoid the common filament 3D printing issues that are caused by under and over extrusion.
Lightweight 25 mm pancake stepper with 18 N/m torque.
