3D Printer & CNC Spare Parts
16 products
Over time, 3D printers and CNC machines require spare parts due to wear, damage, or upgrades. Selecting the right component is crucial for maintaining machine performance, ensuring print or machining quality, and minimizing downtime. In this category, you'll find a wide range of original and compatible spare parts—from nozzles to stepper motors, belts to linear rails.
3D Printer Spare Parts
- Hotend & Nozzle: Brass, stainless steel, or hardened steel nozzles with varying temperature resistance for different filament types.
- Heated Bed & Thermistor: Replacement aluminum beds, PEI sheets, or magnetic build surfaces to solve adhesion issues.
- Belts & Bearings: GT2 belts, idler pulleys, linear bearings (LM8UU), and motion system components.
- Stepper Motors & Drivers: NEMA17 motors, silent drivers like A4988 or TMC2209.
- Control Boards: Mainboards, touchscreens, power supplies, limit switches.
CNC Spare Parts
- Spindle & Collet: ER11/ER16 collet sets, brushed/brushless spindle motors.
- Motion Components: Linear rails, lead screws, anti-backlash nuts, couplers, square rail bearings.
- Control & Power Units: Breakout boards, USB/LPT controllers, relays, power supplies (24V/48V).
- Wiring & Connectors: Stepper motor cables, drag chains, sockets, connectors.
When buying spare parts, always verify the model number, voltage rating, and mechanical dimensions of your existing component. For example, choosing the wrong stepper motor torque or step angle, or an incorrect collet diameter or spindle holder size for CNC, can cause major compatibility issues and lost time. If original parts are unavailable, consult user reviews and technical documents when considering compatible alternatives.
