The Geeetech A20M 3D printer for home provides immaculate performance, demonstrating precision and high-quality printing. It is capable of printing in mixed colours, which adds vibrance and versatility to the printing experience. This device features a premium-quality extruder, built for higher accuracy and clean results. The extruder ensures amplified heat dissipation, which protects the extruder itself and the nozzle from overheating. With a printing size of 255-255-255mm, it can create different sorts of models, toys, household items, and much more, using various filaments like HIPS, PLA, ABS, Flexible PLA, etc. The unique design of wheels and rails ensures smooth motion, thus providing a better printing experience and less trouble. The Geeetech A20M will work with Windows, Linux and Mac so that no one will be left out.


Key features

  • Mixed-colour printing

  • This feature will definitely spark interest and make printing much more fun. It adds that extra pinch, especially for toy and miniature printing.
  • Extruder and nozzle

  • They are both built with premium-quality materials with best printing experience in mind. Correct heat dissipation and nozzle precision guarantee the desired result.
  • V-shaped wheels

  • The wheels and rails on the Geeetech A20M 3D printer are meant to minimise imperfections due to friction.
  • Open source control board

  • This is an excellent source for learning and upgrading the device - more than a desirable feature for people who plan on exploring the 3D printing world further and installing upgrades to their existing devices.
  • USB and SD card slot

  • They will both come in handy in different situations, so why choose one or the other when you can have both providing a convenient offline printing!
  • Filament detection

  • The printer will let you know if there’s a glitch in the filament flow, or when it simply ran out. Thanks to this feature there won’t be damage to the model itself and the device will start right where it left off whenever the problem is eliminated.

Additive manufacturing or 3D printing is the technology where a three-dimensional object is being printed, layer by layer from a CAD model. Each 3D printer operates with special software, and the 3D models to print can be either downloaded or designed.
There are many different ways to carry out the printing process itself. The main distinctive feature between different printers and technologies is the thickness layer - the thinner the layer, the better and smoother the end product. The difference may be between a couple of millimetres to a couple of microns.

There are many areas of use for a 3D printer, from creating a home decore to education and industries. When it comes to industries, a 3D printer can innovate the production process of individual parts, bringing new materials to light and lifting the level of quality.
3D printers can easily be used by tech-fans, people who like building models, cars, aeroplanes, and others, and also by those who see it as a fun hobby. Most intricate models, the smallest parts, and complicated shapes can be printed.

Many various 3D printing processes exist. The first one ever created was SLA. However, the most commonly used one today, especially for educational and home use purposes as a desktop printer is the FDM (Fused Deposition Modeling). They are comparatively cheap and easy to use, hence their overwhelming popularity.

The most commonly used materials are plastics that include PETG, ABS, and PLA. Of course, many other materials can be used in 3D printing with FDM technology; however, their use depends on the printer itself and its ability to process them.

I'm quite happy with this device overall. I've been experimenting with it for a while now and have to say, the articulated models I've tried turned out great, and the joints are flexible. The overall quality level is wonderful, considering the $400 price tag. I've ordered the glass bed already, so I'll experiment with that some more

I had a tough time figuring out how to handle the filament. I couldn't really get the hang of loading it correctly and had a hard time with the release lever on the extruder. But as they say, practice makes perfect and I got the gist after a few trial and error sessions. The filament sensor is a truly great feature, but didn't really work that good for me. I've had a glitch only once, and the end of the filament got stuck in the detector.

First of all, this printer has the power supply and the motherboard underneath the platform rather than next to it, which was much more convenient for me. The printer was generally easy to assemble and didn't require to square up and meddle with the lower frame.
