MK8 Stainless Steel Extrusion Gear 3D Printer Extruder Parts for 1.75mm Filament

MK8 Stainless Steel Extrusion Gear 3D Printer Extruder Parts for 1.75mm Filament

The MK8 stainless steel extrusion gear is a small but crucial part of any 3D printer extruder system.

• Designed to fit onto the shaft of NEMA 17 stepper motors, this gear securely grips 1.75mm filament and pushes it smoothly towards the hot-end for consistent and high-quality prints.
• Direct drive filament gear featuring a built-in grub screw, the coupling and gear are tightly secured to the shaft, while the carefully machined threads on the outer surface ensure a strong filament grip without cutting or scraping.
• Ideal for direct drive extruders, this MK8 extrusion gear delivers reliable performance for long-term 3D printing projects.

Specifications

• Outer Diameter: 9mm
• Bore Diameter: 5mm
• Height: 11mm
• Material: Stainless Steel
• Filament Compatibility: 1.75mm

Features

• High-Quality Stainless Steel: Durable and corrosion-resistant, ensuring long lifespan and reliable operation.
• Direct Drive Compatibility: Specially designed for MK8 extruders with a 5mm inner diameter and 9mm outer diameter, maintaining high torque for smooth filament extrusion.
• Precise Machining: Carefully CNC-machined teeth and threads provide a secure grip on 1.75mm filament, preventing slipping or grinding.
• Enhanced Performance: Supports consistent extrusion for better print quality and smoother operation.
• Ideal Application: Perfectly suited for MK8 extruders, particularly on NEMA 17 stepper motors, for precise filament feeding in 3D printers.

Advantages

• Reliable Filament Feeding: Provides a strong and consistent grip on 1.75mm filament, helping maintain smooth extrusion.
• Reduces Filament Slipping: Precision-machined teeth grip the filament securely during continuous printing.
• Consistent Extrusion: Helps maintain a steady filament flow to the hotend, supporting more uniform print layers.
• Durable Stainless Steel: Offers good wear and corrosion resistance for long-term extruder use.

Applications

• 3D Printer Extruders: Used in MK8 extruder assemblies to grip and feed 1.75mm filament smoothly toward the hotend.
• Direct Drive Extruders: Suitable for direct-drive systems where the extrusion gear is mounted directly on the stepper motor shaft.
• Bowden Extruder Systems: Can be used in compatible Bowden setups to push filament through the PTFE tube toward the hotend.
• NEMA 17 Stepper Motors: Designed for compatible 5mm motor shafts, commonly found on 3D printer extruder motors.

Package Includes

• 1 Piece MK8 Stainless Steel Extrusion Gear (with built-in grub screw)
