Kingroon KP3S, a mini 3D printer that will impress you

The Kingroon KP3S It’s a very small, affordable, yet capable 3D printer that’s shaping up to be a recommended option for beginners or anyone with small printing needs. It is one of the most affordable 3D printers on the market, offering a humble 180 x 180 x 180mm build volume and respectable print quality. It also comes 95% pre-assembled and includes all the features you’d expect from a higher-end machine, and that’s reason enough to take a closer look.

If you are not convinced by the small build volume of the Kingroon KP3S, you might want to go for the Artillery Horneta machine that offers 220 x 220 x 250mm and is in the same price range.

A 3D printer that should not be judged by its size

The first thing you’ll notice about this printer is its diminutive size by industry standards, but don’t be fooled, it’s a worthwhile machine and you’ll see why. Going into details, it has some size dimensions 280x285x370mm and it weighs only 6 kilograms, so it goes without saying that it is quite compact.

Design and construction of the KP3S

The machine has a cantilever design, very similar to the popular Prusa Mini+, likewise, it has a single arm, boasts a direct extruder, but lacks a handle, although honestly speaking, it does not need the latter.

As we mentioned earlier, the Kingroon KP3S has a direct drive extruder. This is seen by many as the “gold standard” due to its advantages over the Bowden variant, as it has a better success rate when working with flexible filaments like TPU.

Kingroon KP3S - Components

The fact that the Kingroon KP3S is equipped with dual XY linear rails is another curious thing to see in a printer in this price range. Linear rails are generally more expensive than regular wheels and feature a smoother motion, which in turn should contribute to print accuracy.

To top it off, the KP3S comes out of the box practically assembled, so it will be a breeze to get up and running, even for novices.

In the meantime, control box and spool holder are located to the sideon the table, which is a potential problem as the filament could get tangled in the middle of a print if the spool doesn’t keep rolling.

Finally, the machine has a 2.8-inch LCD touch screen which provides access to a somewhat outdated user interface. Be that as it may, it is available in Spanish and 8 other languages.

Printing and features

The Kingroon KP3S 3.0 boasts a fairly small build volume even for a low-end 3D printer. we talk about alone 180x180x180mmso if you plan to print something important or have professional needs, this printer is not for you.

KP3S print volume

Leaving that detail aside, the Kingroon KP3S 3.0 can work with filaments such as PLA, ABS, PETG and TPU without any problem, in addition, it exhibits a printing speed that goes from 30 to 100mm/s.

We also have to direct our attention to the warm bed, specifically because of the presence of a flexible magnetic print surface which allows users to remove 3D models easily.

Kingroon KP3S - Magnetic surface

To put the cherry on the cake, the Kingroon KP3S is one of those support print resume after an interruption, such as a power outage.

The print quality of the Kingroon KP3S is more than decent for its price. However, online testimonials point to room for improvement through some calibration and temperature adjustments.

Changing the subject, the KP3S includes a full 32 bit motherboard with silent TMC2225 stepper drivers. In this sense, it is a silent 3D printer for what can be expected from such a product; you can still hear the extruder and motherboard fans, but that was to be expected.

On the other hand, this printer would be a 100% safe recommendation for beginners if it had automatic leveling, but that is a lot to ask of a model that costs less than 200 euros. However, there is a slot available to add a probe in the future, so all is not lost.

Connectivity and software

There is not much to say in this aspect, the Kingroon KP3S 3D printer works with any cutting software, including the popular Utimlaker Cura. However, at the time of writing there is no perfect print profile for this printer, but that may change in the future.

If we talk about connectivity, then it only consists of micro-SD slot and USB port to connect to the computer.

What does stand out in this section is the possibility of modifying the firmware, which is one of the inherent advantages of marlin.
