When your package arrives, you will get the following items inside the box:

  • Partly pre-assembled Easythreed K7 3D printer
  • Necessary tools for complete assembly
  • White PLA filament (enough for one or two small prints)
  • Set of instructions for assembly and operation
  • TF card
  • USB adapter
  • USB cable
  • Pre-sliced objects
  • Slicing software for printing

The Easythreed K7 does not have a display. Therefore, while it’s marketed for beginners, some people can find it challenging to use. However, this obstacle is not something that is too difficult to be overcome. Simply following the instructions will  help you get the hang of it. Even if you’re new to 3D printing, you can still use the printer without a problem.

Design and Build Quality

The compact size of the Easythreed K7 3D printer makes it easy to store or transport. The printer also has removable elastic magnetic suction stickers that make it easy to remove prints.

Despite its small size, the printer offers a build volume of 100 x 100 x 100 mm. This is quite enough for beginners to experiment 3D printing, and even slightly larger than what is offered by its competitor, the Kokoni EC1.  The build volume means you can only print small items. However, the small build volume it is not a major drawback as it is still sufficient for most hobbyist and educational purposes.

The K7 3D Printer has a small build volume of 100 x 100 x 100 mm.

The small 3D printer has an impressive printing accuracy. Its accuracy precision is low as 0.1mm to 0.4mm. Therefore, it produces vibrant and smooth prints. The latest technology standard 0.4mm metal nozzle is used on this unit. The improved extrusion technology eliminated nozzle clogging and prevents subpar extrusion.

The nozzle heats up fast, reaching 230°C in just 3 minutes. The maximum temperature reached is 230°C, which means you experiment with different types of  PLA filaments.

Ease of Assembly

The Easythreed K7 3D printer has a simple assembly process. The printer comes with a clear instruction manual and all the necessary tools for assembly. The manual is easy to follow, even for beginners. You will be able to assemble the printer without any difficulties.

The assembly process takes approximately 20-30 minutes. The process includes attaching the printer’s frame, installing the print bed, and mounting the filament spool holder. The printer’s compact size makes it easy to handle and assemble on a small 3D printer table or desk.

Ease of Use

We would have preferred if the Easythreed K7 had a touch screen to enhance intuitiveness and user-friendliness. The current process of switching between feed mode and retract mode for filament changes can feel somewhat. I mean, since there is no temperature display, waiting for the nozzle to heat  can feel like a guessing game.

Of course, given its low price, the K7 Easythreed lacks certain features such as automatic print bed leveling or a filament sensor. These omissions seem to be a trade-off to maintain affordability and cater to its intended entry-level user base. Despite these shortcomings, reading the instruction manual and some hands-on experience can make this 3D printer reasonably manageable, even for beginners.

We don’t expect these challenges to be major dealbreakers, especially when considering the printer’s cost and the impressive printing accuracy it achieves after calibration.

The print head of the K7 features a compact design and is encased in robust plastic. The plastic has two purposes; offer protection from the heat generated by the hotend’s power, and ensure user safety by minimizing the risk of accidental burns or damage to internal components. Enclosing the print heads makes the printer a relatively safe choice, even for younger users.

Leveling the Printer

The Easythreed K7 3D printer requires minimal calibration. The printer’s assisted manual leveling system makes it easy to level the print bed, since the printer guides you through the process of leveling the bed. The leveling ensures that the first layer of the print adheres properly to the bed, resulting in better print quality.

The printer provides some assistance with leveling, an essential step in the initial setup. Instead of adjusting the print head through a menu, the printer features four buttons located on the base. When you press these buttons, the print head moves to each corner. At each corner, you’ll need to level the print bed manually using the paper method.

To do this, you insert a sheet of paper between the nozzle and the print bed, and then you adjust the bed’s height until the nozzle gently holds the paper. The objective is to maintain a small and consistent gap across the entire bed, ensuring that the first layer of your print sticks evenly.

Once the leveling is complete, you can press the home button to reset the printer’s position.

Thanks to the step-by-step manual, assembly only takes about 15 minutes. All mechanical and electrical components are easily installed in place without the need for tools.

Overall, the Easythreed K7 3D printer’s assembly process is straightforward and easy to follow.

Printing Performance

The Easythreed K7 mini 3D printer’s build volume of 100 x 100 x 100 mm is suitable for small prints. The printer can print at a speed of 10-40 mm/s, depending on the complexity of the object being printed. During testing, I discovered that adjusting the speed to approximately 20 to 30 mm/s, after calibration significantly improved print quality.

When setting the print speed, it’s important to consider the printer’s lightweight construction and single Z-axis. These two can affect the unit’s stability at higher speeds, potentially resulting in print errors like ringing or ghosting. To achieve optimal results, careful calibration and speed settings are key.

The K7 uses a direct drive extruder. This means that the filament is fed directly into the hotend. Therefore, the filament is melted evenly and consistently, resulting in better print quality. The printer has a nozzle temperature range of up to 230°C, which is sufficient for printing with most types of filaments.

Printing the Benchy

It also has a non-heated removable print bed. When prints are finished, you can easily remove them from the heated bed. However, one potential drawback of a non-heated bed is that you will be restricted on the materials you can use. For this machine, you can only use PLA. As such, if you are looking to make strong functional parts with high-temperature materials like ABS, you will need a different machine, such as the QIDI X Smart 3.

Straight out of the box, the printing quality of the Easythreed K7 is average, especially when using the pre-loaded TF card models. This is to be expected, given the printer’s low price and its target audience.

The quality of print out of the box is average.

However, fine-tuning and calibrating the 3D printer can result in improved print quality. We found out that 3D printer can exceed initial expectations and deliver competent prints when you get the correct print speed settings.

Post-calibration, I was able to produce impressive models, including ghost models and a 3DBenchy with high printing accuracy.


The Easythreed K7 3D printer offers versatile connectivity options. Included in the package are a TF card, USB adapter, and USB cable, which you can use to transfer files from computer or other devices to the printer. Whether you prefer the convenience of a TF card, the versatility of a USB adapter, or the direct connection via USB cable, this printer ensures that you have the flexibility to choose the most suitable method for your needs.

Furthermore, the package goes a step further to enhance user convenience. With pre-sliced objects and slicing software included, you can start printing immediately after assembly. This means you can access a library of pre-designed models or customize your own creations with ease. The combination of these features simplifies the process and reduces the barriers for beginners and experienced users alike, making the Easythreed K7 3D printer a user-friendly choice for all your 3D printing projects.
