Reliable filament feeding for the Bambu Lab A1 series

The 3dacc feed gear assembly is a compatible replacement part designed for the extruder of Bambu Lab A1 and A1 mini 3D printers. The drive and driven feed gears grip the filament together and move it towards the hotend. Replacing the assembly is suitable when the original gears are worn or damaged, or when material feeding problems occur. It allows you to repair a stressed part of the extruder without replacing the entire extruder unit.

Main benefits

• Compatible with Bambu Lab A1 and A1 mini
• Restores reliable and even filament feeding
• Practical replacement for a worn extruder assembly
• Design consisting of a drive and driven feed gear
• Designed for standard filament with a diameter of 1,75 mm
• More cost-effective servicing than replacing the complete extruder

When to replace the assembly

We recommend considering replacement if filament slipping, irregular extrusion, extruder clicking, or visible wear on the feed gears occurs. Before replacement, it is also advisable to check the hotend for blockages and verify the condition of the filament being used.

Installation

Unload the filament before installation, allow the hotend to cool down, and turn off the printer. Replacement requires disassembling the relevant part of the print head. After installation, check that the mechanism moves freely and perform a test filament feed.
