Bondtech DDG extruder for Ultimaker 3

Bondtech DDG extruder for Ultimaker 3

Bondtech DDG Extruder for Ultimaker 3. This extruder replaces the factory extruder and mounts.

• Bondtech DDG Extruder for Ultimaker 3 is a high-performance replacement extruder designed to directly replace the factory extruder and mount in the same position.
• For Ultimaker users in India who want more reliable filament feeding and fewer extrusion issues, the DDG upgrade kit provides a quick installation path with minimal effort—typically around 10 minutes.
• At the core is Bondtech’s proven DualDrive technology, which grips filament from both sides for slip-free feeding.
• This helps reduce under-extrusion caused by grinding or filament slipping, especially on long prints and retraction-heavy models.
• The extruder includes adjustable tension, allowing you to fine-tune grip pressure for different materials, improving consistency across PLA, PETG, Nylon, and other filaments (material profile dependent).
• Durability is improved with nickel-coated hardened steel drive gears (as stated), designed to feed standard and abrasive materials with higher wear resistance than softer gear materials.
• Housing parts are professionally 3D printed in polyamide (nylon) for strength and precision (as stated), supporting stable alignment and reliable feeding over long-term use.
