| 3D FDM Printer | 500mm/s | CoreXY |

Kingroon KLP1, the newest and first CoreXY 3D printer from Kingroon.

Kingroon has several 3D printers in their catalog but this is the first time that they develop and release to the market a CoreXY model.

It is worth mentioning that Kingroon has different variants of the Kingroon KLP1:

• Kingroon KLP1 without screen
• Kingroon KLP1 with screen
• Kingroon KLP1 with screen and camera
• Kingroon KLP1 legacy, older discontinued variant that had a smaller printing volume

The Kingroon KLP1 comes in a substantially smaller packaging than other 3D printers, with a taller but narrower dimension.
Inside you will find:
• Diagonal pliers
• Touch pen
• Filament sample
• Assembly tools
• Replacement nozzle
• Grease
• Needle
• Power cable
• USB-C cable
• Tubing replacement
• Assembly screws
• Acrylic panels
• EMMC adapter



The Kingroon KLP1 has a CoreXY design, which consequently means that the axis move differently than you are used with standard 3D printers.

The Kingroon KLP1 has a printer head that will move in the X-axis and Y-axis direction (which means it goes from left to right and from back to front) but does not moves in the Z-axis (up and down). Instead, the bed itself is the section that will move in the Z-axis direction (up and down) and not back and forth on its Y-axis as a typical 3D printer.

Also, the machine has a different approach on the overall construction, with a built-in enclosed shell that is part of the body of the printer itself – this makes the printer a bit bigger than other 3D printers with the similar printing volume.

As you can see from the photos, the printer also has 2 opening doors to access the prints; a front door that opens sideways and a top lid that opens up – both doors have a magnetic closing system that secures the door in place when closed.

You might notice that there is no visible spool holder on this printer, this is because the brand has placed it on the back panel of the shell as a backwards protruding element.

On the front bottom left corner you will see a big “KINGROON KLP1” writing, this piece has a backlit LED light that will turn on as soon as you power the machine.

On the left section of the shell you will find the I/O connectors of the machine while the back holds the power connector and switch.

Due to the enclosed design of the CoreXY printer, it would had been a smart choice to add a LED light inside the enclosure.

An odd thing that we have seen is that according to the listing from the brand, the Kingroon KLP1 should have 4 acrylic panels throughout its body but our unit has 2 acrylic panels which are the front door and top door but the lateral sections of the case in our unit are actually made of metal. It is fair to note that the brand does name an “Old Version” and a “New Version” of the Kingroon KLP1, yet our unit fits the specs of the new version.




Being a CoreXY machine with an enclosure you might think that it would come 100% assembled and ready to use from factory but this Kingroon printer will need a few pieces to be put in place like the acrylic panels, spool holder, door hinges, knobs and freeing the axis locks.

When compared with other FDM printers, resin printers and laser engravers, the Kingroon KLP1 required less assembly steps to get it fully assembled.



Seeing a full-featured display screen in a Kingroon printers a nice upgrade by the brand.
The display has a good dimension to be usable and provide plenty of information thanks to the 3.5 inches of diagonal size.
The screen is not only full-colored but also touch sensitive to finger inputs and to an included touch pen. This is not a standard mushy touch pen but an EMR pen like what Wacom and pen displays/graphic pen monitors use; as a matter of fact we tried the endless amount of EMR pens that we have from pen displays that we have reviewed and all of them worked and were compatible with the touch screen of the Kingroon KLP1.
The default fonts used for the screen are tiny and hard to read but through the menu you can select several other fonts sizes. Once you set the fonts size to a more comfortable one, the screen actually provides excellent resolution for sharp icons, graphs and fonts.
Moreover, the display is visible even with the door cover closed but you cannot access it unless you open the door.
The screen provides more in-depth information than most screens of other 3D printers and laser engravers, allowing access:
• Files navigation, including details of printing times estimation and file size
• Files printing
• Files lists re-ordering
• Deletion of files
• Preview of sliced files
• Live graphs with info the printer
• Live details of different sensors and elements of the machine
While printing, the screen will show details such as:
• Printing speed
• Acceleration
• Coordinates
• Nozzle and bed temps
• Elapsed time
• Remaining time
A nice details it is that instead of starting to count the time when the printing process has begun, the KLP1’s times calculations also measure the needed time to heat up the bed and print head, which nearly no other 3D printer does.




The Kingroon KLP1 is mainly used through the touch screen and it is nice seeing the addition of a touch pen as some UI elements are a bit difficult to navigate with the fingers.

In addition to the standalone operation of the machine through the touch screen, the Kingroon KLP1 can be used wirelessly through the UI of the network interface that is accessible from any web browser by inputting the IP address of the printer or http://mkspi

Either the touch screen or the web UI allow complete access to all the functions, settings, calibration, leveling and stats of the machine.

It is worth noticing that if you are used to operate other touch screens like your smartphone, you will definitely see that the one on the Kingroon is laggy and choppier with a clearly less snappy responsiveness. If you want a less nerve wrecking experience, definitely use the included pen to operate the touch screen.




As with other 3D printers that we have reviewed from the brand, the Kingroon KLP1 has a solid metal construction with a hefty weight to it (14Kg)

Internally, the machine sports a Klipper firmware mainboard and quality build components that include ball bearing fans, metal hotend with ceramic core; to support and move the Z-axis of the bed, the machine has 3 rods dedicated exclusively to it.

Also, the machine has a filament detector that is a neat feature to avoid totally ruining an ongoing print if you run out of filament.

A fun detail, you can see on the printer head some pieces that are actually 3D printed with PLA filament (or other filament) coming directly from factory.

A drawback that we noticed is that the machine does not have manual adjustment wheels for manual fine-leveling of the bed nor we could find any type of user-friendly belt tensioner system.




The Kingroon KLP1 has 4 input/output connectors that include an USB 3.0, 2x USB-A 2.0 and a RJ45 ethernet.

These connectors allow the machine to connect to a local network through a RJ45 ethernet cabling, connect Udisks to print files in standalone mode and to use addon accessories like tan EMMC reader (included) to flash the EMMC of the printer or connect and use a control camera.

On top of that, the Kingroon KLP1 has a built-in WiFi module that enables the machine to connect to a wireless network.

Despite being informed by the user manual, that the printer needs to flash a manual file with your WiFi info in it (as seen when we reviewed other printers from Kingroon), the KLP1 actually does not need this tedious process as through the touch screen you can access a dedicated function to connect the machine to a WiFi network.




Since the version of the Kingroon KLP1 that we are reviewing tis the newest one, this means that this model has a larger printing capacity than the older one, reaching up to 230*230*210mm. Either the new or old version comes with specs such as 500mm/s printing speeds 20000mm/s2 acceleration and support for pressure advance and input shaping features.

The Kingroon KLP1 includes many features that are not found in much more expensive printers, like an auto-loading filament design that worked smoothly fine while testing the machine, where we simply needed to thread the filament through the filament tubing and the machine took care of all the rest.

In addition to this, the KLP1 has a simple auto-leveling system that requires just manually adjusting the Z-offset with an A4 paper sheet and then going through the auto-bed mesh calibration to benefit from the 36-point offset compensation calibration.

The bed is equipped with a magnetic PEI sheet to optimize the print’s adhesion and easier removal after the job is done; indeed, as proven with PEI sheets, the one from Kingroon works excellently well and presented pristine solid adhesion on all print tests, no unexpected popping while printing.

Noise-wise, the Kingroon KLP1 is noticeably noisier than other 3D printers that we have tested but closing the acrylic doors help to reduce the audible noises coming from the axis, wheels, motors and fans. Most probably, if the machine had belt tensioners, the grinding noises would had been greatly attenuated.

During the tests, the extruder never got stuck nor went crazy handling the filament perfectly well and aiding to perfect clog-free, blob-free performance.




We did a test of an included Benchy file in it smore extreme version labeled “violent” which uses the max. speed values for the print, with 500mm/s.

This file is intended to be printed with a rapid PLA filament so we tried to see how the print would come using a Creality Hyper PLA filament. As you can see from the photos of the print test, the Benchy came remarkably well, with no single stringing sign.

The print was estimated to be completed in 19 minutes and it did, effectively finished in the 19 minutes predicted plus 3 minutes were additionally taken by the preheating process.

We then printed a vase using the maximum height printing capability of the Kingroon KLP1, which took 1:06 hours and was printed flawlessly on the very first attempt without showing any printing errors nor issues while carrying on the job.

As a further test, we proceeded with a very detailed bust that we usually use as a reference for many 3D printers. The design has 100mm in height and was printed with very good fine detail.




While printing and even the “violent” Benchy that was pushing the max speeds of the machine, the printer showed a power consumption oscillating from 95W to 211W with an average of 150W more or less. While preheating, the consumption was around 260W to 290W.

This was quite an impressive low power consumption that was even lower than the ELEGOO Neptune 4 PRO with its smart dual-zone heating bed.



A nice detail from Kingroon and the Kingroon KLP1 is that the printer is compatible with all mainstream 3D printers software, including Cura, PrusaSlicer and Orca Slicer.

On top of that, the brand includes the configuration files for each slicer software.

This is a welcomed addition as of today the Cura version 5.7 does not list the Kingroon KLP1 as the presets for printers.

On the other hand, the machine does require some manual intervention from the user to get it configurated, added and correctly set to run with PC slicing software. For power users this will not be a challenge but it might make new, first-time 3D printer owners to freeze up in front of the manual process of dealing with these config steps – this is not a specific detail of the Kingroon KLP1, the Kingroon KP3S Pro V2 that we reviewed in the past required the same exact steps.

Also, the files provided by the brand were wrongly spelled, leading to Cura crashing; for example the file KINGROON_KLP1_normal.inst.cfg was wrongly spelled as “KINROON” and the print volume of the machine is set as the older version of the KLP1 at 210x210x210mm instead of 230x230x210mm.
