Unboxing and Assembly

Compared to most budget desktop FDM 3D printers, the Creality K1 is shipped with extra protection. Instead of just a cardboard box, this machine is shipped in a crate made of plywood.
Update: According to messages on social media, some of the machines were shipped in only cardboard, and issues happened during transportation.

It takes a few minutes to remove all the packaging, install the filament holder in the back, and assemble the screen. The only hex key I had to use was to attach the door handle and to remove the protective screws.
– Do not forget to unscrew. Three screws keep the printer’s bed well secured during transportation. Yellow labels indicate their location, as the screws themselves are quite small and easy to miss. There are enough messages; even when the 3D printer is ON, they will pop up before anything else.

– Self-inspection. Before getting to the main screen, the machine goes through a self-inspection. I absolutely love this feature as it is very user-friendly; there’s no need to manually calibrate anything. Both Input Shaping Calibration and Automatic Bed Leveling take just a few minutes. On the Sovol SV07 Plus, for example, Input Shaping calibration involves attaching an extra device, and the process involves a few steps.

– Touch Screen. The 4.3-inch touchscreen is very well thought out, intuitive, and user-friendly. All models have preview icons, which makes it easy to find the models whether they are loaded on the machine or on a USB stick. The history of the printed models is also available. However, there aren’t many options to adjust settings live during the printing. For example, to increase print speed, users must do so via an app or the Creality Print software.

Before every print, the machine offers to perform calibration. I unticked this option in all cases, as it saves time and the printer still performs a quick Z offset calibration anyway.

– Noise and Vibration. The machine is noisy, especially when printing at high speeds and with all fans ON. Apparently, this is the new normal for all machines that have entered the ‘print speed race,’ as the last four Klipperized machines I tested had the same issues. To maintain a speedy flow and high temperature, bigger fans are involved.
At high speeds, vibration is also significant. The table should be stable; mine was not so much. After a few hours of printing, I found some light items on the floor as vibrations slowly moved them off the table. Please bear in mind that this vibration didn’t affect the print quality; this is where Input Shaping does its job.


AI Camera and Timelapse

An AI Camera for the K1 is available as an optional, inexpensive add-on and it is included when purchasing Creality K1 Max.

I had a good experience with such a camera on my AnkerMake M5, which I reviewed recently. Not only does such a camera allow us to monitor the print process whenever we want, but it also captures decent timelapses. The Creality AI Camera can be purchased via the Official Website or on Amazon. It’s very easy to assemble with just one screw.

The only con here is the timelapse file format. Despite managing to retrieve the file from Creality PrintDeviceTimelapse Video, I could not open it on any player apart from using the Creality Cloud App. If there are changes, I will leave instructions here.

– Sleek Design. A special note about design: LED lights and a dark transparent enclosure make it look futuristic and cool, especially in a dark room. By the way, it is a rare case when LED lights do work well, and I prefer it more than other light sources in my workshop. Overall, with the spool hidden behind, this machine looks genuinely well.

Included Test Files and Prints

Initially, there were three pre-sliced test files included. The Speedy 3DBenchy was printed, as promised, very quickly in approximately 20 minutes. The included Creality Hyper PLA performed very well, leaving barely noticeable amounts of cobwebbing. For such speed, it is a very impressive Benchy.

Without looking properly, I started the next print, which was the Flexible Cat. Usually, for prints that start with many multiple independent parts, I apply extra glue such as Magigoo for additional bed adhesion. To my delight, this print was completed well without glue and without issues.

To test the maximum 600mm/s speed, there was a model in vase mode. Nothing special in design, just an object printed quickly in vase mode that had a good clean result upon completion.

This dragon is not included but was sent to me by Creality representative along with a bunch of other pre-sliced G-codes. I’m still looking for the original creator of this model so I could leave credits here. The 20cm model is gorgeous and printed very well in approximately 11 hours. This model showcases the K1’s capabilities very well.


Slicer Software – Creality Print, Simplify3D

Generally, I am happy to see Creality finally has their own slicer. I sliced a lot of models using default and slightly tuned settings, and it worked well for me. If you go to Creality Print – Device – Details, it is possible to see the screen that very much resembles Klipper’s Fluidd interface. There, you can tune settings live, such as extruder temperature and printing speed. Via this screen, it is possible to start the print without the need to use a USB stick.

On one occasion, I could not slice the file and had to turn to Simplify3D. Simplify3D already has a Creality K1 slicer profile, and after tweaking a little bit more, I finally printed very challenging models that have a lot of retraction and very long bridges.

Apart from this, another case where Simplify3D and ideaMaker can help is when custom support placements are involved from the model itself in order to reduce post-processing.

Firmware – Modified Klipper

– No access to config. This prevented me from applying an automatic pause at a specific layer height. I was able to achieve an automatic pause for a filament change on such Klipperized printers as the Elegoo Neptune 4 Pro and Sovol SV07 Plus. If I find a way around, I will update this post accordingly.

WiFi, App and Creality Cloud

It took no more than a few seconds to connect to the internet, and again, I find it very addictive to send the files to the machine remotely. Freedom from a USB stick.

– 3D Model Library. Creality Cloud’s 3D Model Library is a feature-rich platform with 400,000+ 3D models. With ease I downloaded and printed my own Easter Bunny model.


Other Test Prints

This test model is challenging. It tests bridges, cooling, tolerances, and more, all at a very high speed. I printed the same file twice with Creality Hyper White PLA and SUNLU Green Antistring PLA. Both filaments are different, and I achieved slightly different results. There was some sagging on both of the prints; nevertheless, I believe it is an astounding result considering the print was completed in just two hours.

Together with ‘high-speed printing,’ there is a new range of filaments appearing on the market. While Speed/Hyper PLA has been around for a while, Antistring PLA is a new thing. I must admit that SUNLU Antistring PLA, which can be found on Amazon, performed very well, and indeed there was much less stringing on various retraction-rich prints.

Flexible Articulated Model with Many Parts

Coincidentally, I reviewed the Creality K1 during the Halloween season – the most popular season in the 3D printing community. Obviously, I printed zombies and skulls. One of the remarkable models this year that caught my eye is the Flexy Zombie Dragon by Toonz Factory. In SUNLU Green Antistring PLA, it looks stunning as it is, without painting.

70% Scaled Flexi Zombie Dragon

I used default settings in Creality Print software without adhesion settings to avoid excessive cleaning. The 70% scaled model took only 4-5 hours to print. As usual, Magigoo helped with bed adhesion. It was very easily removed from the bed and assembled, namely attaching wings and head to the body. The model is not just wiggly but can also take various positions. This model is definitely one of the favorite models in the Halloween 3D Print Ideas collection.

Bed Adhesion Glue for K1

Here is the Post-it Note holder together with Magigoo from Amazon. As the model is printed on the back, the first layer involves a lot of independent isles. Extra bed adhesion with Magigoo always makes sure there are no hiccups.

In order to print this model without supports and avoid sagging in the pen holder area, it is important to switch to Wall Ordering to Outside To Inside in the Advanced slicer settings.


3D Printing in ABS – Fail and Success

ABS filament is very sensitive to adhesion, even with Magigoo and enclosure. The thing is, after I moved my printer from table to table, the bed became uneven. And even if PLA prints worked without problems, my ABS print failed at 90% of completion. The part was crooked due to warping forces, and I had to clear a lot of mess.

To fix that, I had to recalibrate the bed again by going to System -> Self Check -> Auto Leveling (and Input Shaping) on the K1 screen. After recalibration, I printed my brackets in ABS filament flawlessly.

It is an ongoing trend in the 3D printing community to print such brackets to build customized filament-holding shelves. To see such shelves in action and view other functional print ideas, have a look at this guide.

Bunny and Filament Dryer

Also, I printed my Bunny in pink SUNLU PLA to test cooling and to check if the filament dryer can co-work with Creality K1. The model’s paws are at a very steep angle; sagging may be seen if there is not enough cooling. The model got completed in about 3 hours with the default settings, and cooling did an excellent job!

The K1 filament sensor was positioned back at the right height, which allowed me to use the filament dryer simultaneously. Whether during printing or prior to printing, such filament dryers can be good companions to keep the filament in the best condition. Read more about filament dryers and how they work on our website.

Organic Supports in Orca and Prusa Slicers

To apply organic supports in order to print some challenging models, Creality K1 range 3D printer users can use either an existing 3D printer profile in Orca slicer or build a custom profile in PrusaSlicer. I managed to fill all needed parameters in PrusaSlicer in order to print our new model from the Toy Pot Planter collection. It came out very well.

Challenging model was printed in less than 7 hours. There are a few guides available to those who want to create a custom profile for K1 on PrusaSlicer. You can also download my .3mf file and retrieve the settings from there via our premium model on Cults.

Long Bridges

Fragmented Skull String Art by 3DPrintBunny is a very good seasonal torture test model for any machine. It has very long bridges and a lot of retractions. Bear in mind that, according to Natalie, it is a simplified version with a solid base. To make the most of her artwork, I printed the first layers in transparent PLA and the rest in Creality Hyper White PLA. This model challenges both the machine and the filament.

On a second attempt, I achieved a better result. I turned the model 90 degrees so the fans don’t stretch the strings and also reduced the Bridging Speed Modifier to 80%. While my strings are not perfect, being very thin on one side, some tuning still needs to be done. Nonetheless, the ability to print such a complicated model in just 4 hours still amazes me.

Manual Filament Changes Mid Print

– Filament Sensor. There is no option to disable the filament sensor via the screen. For quick print jobs, I love to feed the filament directly into the extruder, which greatly speeds up the process. To fool the system, I just kept a bit of filament in and used a manual pause to switch the filament. As a result of the test, I have a Speedy Benchy with 2 color changes.

Featured above is the mid-print filament change performed by manually pausing the machine. It is a relatively easy, but not precise, process. A quick swap is needed if there is a desire to play with colors when 3D printing logos, for example. If I had access to the machine’s firmware config. file via the Klipper/Creality Print interface, I could set up this filament change at a specific layer/height to be automatic and more precise.


Compare to Other FDM 3D Printers

On 3DWithUs, we have a comprehensive comparison guide covering the best budget FDM 3D printers. This printer is in a slightly different category, both price and quality-wise and therefore a new comparison guide is coming soon. Compare to the similar build, volume, and the price range FDM 3D printers:

– Speed. There is fierce competition for speed in the consumer 3D printer market. First, AnkerMake was followed by Bambu Lab, and now Creality came in the form of the Speedy Creality K1 and K1 Max 3D printers.
– Price. AnkerMake M5, Bambu Lab P1P, Creality K1 and Prusa i3 MK4 Kit are in the same price range of $600-1000 depending on campaigns.
– Build. Build-wise, both the Creality K1 and BambuLab P1P are on the same level, featuring a stable CoreXY with an enclosed chamber.
– Multi Culor Option. With Bambu Lab X1 AMS and Prusa MMU already on the market, AnkerMake plans to bring their V6 version as well. Creality still has to offer their version of a multi-color option.

In the comparison conclusion, I would say that the four machines mentioned above are in competition at the moment for the same price range.

Compare to Other Creality Printers

The most recent Creality K1 Max should be a good contender. Even if the price is higher, this machine has a bigger print volume, and if it can maintain the K1’s speed and print quality, it is in a good position. Read the full Creality K1 Max Review by Will Zoobkoff here.

Creality is very well known for its previous CR and Ender series machines. Over the years, various models have been named as the best 3D printers in budget and other categories. With a new flagship, Creality keeps developing their other series of 3D printers as well.
