This is part 2 in a three part series - Part 1 on Upgrading the Gearcase can be found here. Part 3 is coming soon!

The Creality K1, a recent addition to the 3D printing market, offers a range of features designed to cater to beginners and experienced users. While it provides a solid foundation for 3D printing tasks, there are several upgrades available that can further optimize its performance. This article will overview the K1's core features and discuss critical upgrades, including the extruder gearcase, the ceramic hot end, and the potential benefits of integrating a camera. By understanding these upgrades, users can make informed decisions on which are necessary for their needs.

Core Features

The Creality K1, while relatively new to the market, has garnered attention due to its specific set of features tailored to meet diverse printing needs. Here's a breakdown of its primary attributes:

Print Speed and Quality: One of the standout features of the K1 is its ability to achieve print speeds of up to 600mm/s. This speed doesn't compromise the quality, ensuring users can quickly produce detailed models.

Bed Leveling System: A reliable leveling system is crucial for consistent print quality. The K1's innovative approach ensures that the print bed is always perfectly aligned with the nozzle, reducing the chances of print failures.

Extruder and Hot End: The K1 features a new dual-gear direct extruder, which ensures consistent filament feeding. The ceramic hot end, equipped with a 60W heating element, allows for rapid and even heating.

User Interface and Connectivity: The K1 features an interface designed for ease of use, with a touchscreen that ensures seamless navigation. Additionally, it offers multiple connectivity options, including USB and WiFi, enhancing its versatility.

Understanding these core features provides a foundation for exploring the potential upgrades that can further enhance the K1's performance. In the subsequent sections, we'll explain these upgrades, discussing their benefits and how they can elevate the printing experience.

Ceramic Hot End Upgrade: Achieving Superior Heat Insulation and Versatility

The hot end of a 3D printer plays a critical role, melting the filament and ensuring the printer extrudes it at the correct temperature. Within the hot end, the heat break is vital in maintaining temperature stability and ensuring consistent filament flow.

Understanding the Heat Break: The heat break is a narrow tube connecting the cold end (extruder) to the printer's hot end. Its primary function is to prevent heat from traveling up the filament path, ensuring that the filament only melts where it's supposed to. An effective heat break prevents issues like filament jamming and ensures consistent print quality.

The Upgraded Copper Alloy Heat Break: While the Creality K1 comes with a ceramic hot end, the introduction of a copper alloy heat break offers several advantages:

Superior Heat Insulation: Crafted from titanium alloy, the upgraded heat break boasts an ultra-thin wall thickness, providing enhanced heat insulation. This ensures the heat is confined to the hot end, preventing unwanted filament melting.

Increased Temperature Range: The copper alloy heat break can handle higher temperatures, allowing users to print with a wider range of filaments, from standard PLA to more temperature-sensitive materials.

Benefits of the Upgraded Heat Break:

Versatility in Filament Choice: The ability to handle higher temperatures means users can experiment with a broader range of filaments, expanding the possibilities of their printing projects.

Consistent Print Quality: A smooth and consistent filament feed, combined with superior heat insulation, ensures that prints are of consistent quality, with fewer imperfections.

Reduced Maintenance: The upgraded heat break's design reduces the chances of filament jams, meaning less maintenance and downtime for the printer.

We've covered its benefits; now, let's dive into the step-by-step installation of this upgraded component.

Installing the Improved Hot End

This guide will provide a step-by-step walkthrough on installing the improved copper alloy heat break.

Tools and Materials Needed:

  • K1 tool kit
  • Replacement hot end
  • Tweezers or needle-nose pliers
  • Thermal grease

Safety Precautions:

  • Ensure the printer is turned off and unplugged before starting.
  • Allow the hot end to cool down completely if the printer was recently in use.
  • Work in a well-lit area to ensure clear visibility of all components.

Step-by-Step Procedure:

Step 1: Turn off and unplug the Creality K1 printer.

Step 2: Carefully move the print head to a position where you can comfortably access the hot end. Make sure to give yourself plenty of room between the print bed and the hot end. The more space you have, the easier this task will be. If you need more space, stop now and lower the print bed. Then, begin the process again with step one.

Step 3: Using the appropriately sized hex key, remove the two screws securing the fan shroud, granting access to the hot end. Unplug the fan and set it aside.

Step 4: Carefully remove the silicone sock covering the hot end. Remove the two hex head screws on the right and left side. Remove the single set screw in the rear of the print head, securing the heat break. Remember the orientation and position of any wires or connectors.

Step 5: Apply a thin layer of high-temperature thermal compound to the new copper alloy heat break to ensure optimal heat conduction (I could have used a little more but ran out). If I run into heat creep, I will address the issue. Insert new hot-end and secure with hardware. Connect wires to the control board with sweeping bends to avoid kinks, and install a new silicone heat sock.

Step 6: Connect wires to the control board with nice sweeping bends to avoid kinks, and install a new silicone heat sock. Ensure any wires or connectors are correctly positioned and not pinched.

Step 7: Reattach the fan and shroud using the screws you removed earlier. Secure the top of the cover on the pins and slide the bottom into place.

Step 8: Load up some filament and use the automatic extrusion feature on the K1 to fully prime and purge the new hot end. Then, choose a test print to ensure everything is working correctly.


  • If you notice uneven heating or filament flow issues, double-check the heat break's alignment and ensure all connectors are properly attached.
  • Ensure the fan and heatsink are correctly aligned to prevent overheating.

Installing the improved copper alloy heat break can significantly enhance the Creality K1's performance, ensuring consistent heating and expanding filament compatibility. You can seamlessly integrate this upgrade into your 3D printing setup with careful attention to detail and the right tools.
