GEEETECH A20M 3D Printer’s Review


The assembly of this printer, which appears to be simple on paper, is much more difficult in reality. A second pair of hands is recommended to assist in mounting the gantry frame to the base. In addition to the strange logistics of keeping everything in place, the printer came together without much complication.

The biggest problem came when it came time to level the bed. There was a serious bed issue – almost impossible to level. To solve this problem, it is recommended to remove the bed and tighten the wheels of the Y-axis. After some adjustments, the bed slides without oscillation.


The construction of the A20M is really exquisite. There is no separate box for the power supply or main screen, everything is mounted on one unit. The frame, constructed of aluminum, is very resistant. If an area could be upgraded, it would be a redesign of the components under the bed. It is very difficult to reach the wheels of the Y-axis. Facilitating this access would facilitate the adjustment process.

And the final version looks very high quality, well resilient and does not have any extra oscillation when printing. The metal frame is a matte black finish and still comes with some decorative white stripes. The power supply and electrical components are very conveniently housed in a box under the bed.

Performance and Print quality

The bed is huge and the quality of detail is impeccable. And it supports so many types of filaments PLA, PETG, ABS and more. And yet you can use two spools at a time for two-color printing.

From large prints to small projects, this printer can do some beautiful things with seriously fine details. Compared with the Alfawise U20, the quality of the A20M’s detail is definitely superior. The example image shows the printed head of Robotica, a doll created by Shira. You can see fine lines of design, details of the eye and even little dimples on your cheeks.


The print quality is wonderful and definitely worth taking a closer look at. Not the most affordable, there are other competitors with similar proposals cheaper. But if you want great performance and print quality, the price is excellent.
