Creality K1C Review – High Speed 3D Printing Quality Carbon Fibre Prints

Last January, Creality released another 3D printer, which we will look into in this Creality K1C Review. The K1C is an upgraded version of the K1. It features some vital optimisations that improve the printing efficiencies and capabilities of the K1. 

The C in K1C indicates its upgrades for printing carbon fibre filaments. It also denotes including an AI camera on the 3D printer. 

The focus on its carbon fibre is in its updated extruder, which now features an all-metal hotend. This revamped element allows the product to withstand the abrasiveness of carbon fibre filaments. So, it guarantees reliability and longevity when printing. 

In our Creality K1C Review, we will discuss its specifications and features. We will also look into its design, functionalities, and how it fares when we put it to the test. 

Creality K1C Packaging

Like previous products, Creality shipped the K1C in a standard cardboard box. Although the package does not showcase designs like the product image and branding, it provides adequate protection for the 3D printer.

When we opened the box, we saw the K1C protected by laser-cut foam and cardboard on all sides. Since it is pre-assembled, you only need to attach a few parts before using it.

Creality K1C Review – Design and Functionality

As mentioned in our Creality K1C Review, Creality made improvements on the K1C by addressing the issues of its predecessor. You will not notice the differences immediately when looking at the K1C and K1 side by side. 

One of the primary differentiators of the K1C is its nozzle. It can print carbon-fibre-infused filaments like PLA-CF and PETG-CF. Also, the K1 can handle PC, ASA, and filaments requiring higher temperatures.

In addition, it has a more rigid frame that can withstand fast 3D printing speeds. Creality designed its electronics with safety in mind, making it user-friendly for beginners. 

The K1C also has an enclosed layout, making it ideal for maintaining stable temperatures. It is a beneficial feature when printing warp and crack-prone materials due to fluctuating temperatures.

Unicorn Tri-Metal Nozzle

The K1C uses a unicorn tri-metal nozzle. It incorporates copper for efficient thermal conductivity, a titanium heat break, and a steel tip for increased durability. This design resembles the Revo nozzles, making removal easy.

Stepper Motor

Creality used a more conventional-sized pulley as a stepper motor for the K1C. It has smaller diameter pulley gears with around 20 teeth per revolution. It has a decreased size compared to the 40 teeth per revolution used in the K1 and K1 Max.

The older models have more sizeable pulley gears to achieve maximum speed. However, this approach caused issues with VFAs (visible fine artefacts), which were problematic on smaller parts of prints. These problems were evident on the textured surface of prints.

Using more conventional stepper motors in the K1C solved this issue in printing.

Creality K1C AI Camera  

Unlike the K1, the K1C has an AI camera as a standard, allowing you to monitor print progress. Plus, you can record time-lapse videos, which you can save and share after your printing project.

Aside from recording, this AI camera can spot foreign objects on the build plate. It can also detect if a print fails during the process or if a filament forms a load of spaghetti. Also, it can determine if you left the previous model on the build plate.

This AI camera has the same quality as the one in the K1 Max. It may have some flaws, like failing to send alerts when there are failed prints, but its detection is accurate.

Front Door and Hinge 

One thing we immediately noticed while unboxing the 3D printer for this Creality K1C Review was its front door. 

Some users reported the minor design flaw of the K1 and K1 Max was its loose door hinge. According to those people, it caused the door to swing open and potentially break.

Creality addressed this issue by making the door of the K1C sturdier than the older models. The door of this new model has a magnetic closure to increase its durability. Plus, it has enhanced friction on the hinges, allowing you to keep the door fixed at your desired angle.

In addition, Creality added an anti-shatter film on the glass to keep it safer and more protected. Aside from preventing door breakage, the film adds a premium feel and appearance to the 3D printer.

Higher Cable Chain

The cable chain used in the K1C is higher than the K1. Creality increased its height to address the issue of cable chain rubbing and facilitate smoother movement. Also, it minimises possible pinch points for the Bowden tube.


Creality retained the 11cm colour touchscreen on the K1 and K1 Max but made various improvements to its interface. One of these includes allowing the adjustment of print speeds on the fly.

The touchscreen interface is user-friendly and intuitive, making navigation of menus and settings easy. Also, it was highly responsive and did not have lags when we pressed the available options and commands.

Key Features of the Creality K1C

The K1C is an updated and improved version of the K1. But what makes it an excellent investment? Learn more as we discuss its primary features in our Creality K1C Review.

Robust Extruder, Enhanced Reliability 

The K1C has a robust extruder with a ball plunger and bolster spring. It grips on filament tightly to ensure accuracy and reliability when printing.

Unicorn Nozzle 

Another nozzle on the K1C is the Unicorn, built-in with a heat break. It blocks the heat to prevent increasing temperatures on the 3D printer. Plus, you can swap it with one hand when necessary.

This nozzle has a hardened steel tip, allowing it to handle carbon fibre filaments like PETG-CF and PLA-CF. These two materials have superior mechanical strength and stability, making them the best choices in industrial printing.

Dynamically Balanced Printhead Fans

Creality enhanced the cooling system of the K1C by keeping the hot end and part cooling fans dynamically balanced. It prevents the 3D printer from wobbling, ghosting, and ringing.
