Heater block Creality 3D 4001030123 K1 K1Max Black Copper Red

The Creality 3D 4001030123 heater block for K1 and K1Max is a replacement heating element designed to fit the specified models. Manufactured to match the original geometry and mounting points, this heater block combines black, copper and red finishes and is intended to provide stable thermal conduction between the cartridge heater, thermistor and the hotend nozzle assembly to support consistent extrusion and print quality.

Advantages

This heater block offers accurate alignment with K1 and K1Max hotend components and maintains efficient heat transfer due to its metal construction. The color finishes aid visual identification during installation and maintenance. Designed for direct compatibility, it reduces the need for modifications and helps restore original printing performance when replacing a worn or damaged block.

Suitable for

• Replacement of worn or damaged heater blocks on Creality K1 and K1Max printers
• Maintenance and hotend rebuilds that require original form-factor parts
• Users restoring consistent nozzle temperature and extrusion stability

Key specifications

• Type: heater block for 3D printer hotend
• Compatibility: designed for use with Creality K1 and K1Max hotend assemblies
• Materials/finish: metal block with black, copper-colour and red finishes
• Function: provides thermal conduction between heater cartridge, thermistor and nozzle
• Mounting: matches original mounting geometry of specified models

How to use

Power off the printer and allow the hotend to cool before beginning replacement. Remove the existing heater block according to the K1/K1Max service instructions, taking care to detach the heater cartridge and thermistor leads safely. Install the replacement block so that the heater cartridge and thermistor sit in their intended bores and the nozzle threads engage correctly. Tighten fittings to the manufacturer’s recommended torque and check electrical connections before powering on. After installation, perform a temperature and extrusion test to verify correct operation and to re-level the print bed if needed.

Recommendations

Use only with the specified printer models and follow Creality’s service guidance. Inspect wiring and sensors for damage during replacement and apply appropriate thread sealing or thermal paste only where recommended by the printer documentation.
