2019 Geeetech A20T 3D Printer: Review the Specs

Is the relatively inexpensive Geeetech A20T the tricolor printer for you? Read on for our take of this printer’s specs.

Chinese 3D printer manufacturer Geeetech has made a name for itself by pumping out Creality-esque machines at cheaper prices.

Its latest multi-color 3D printers are no different, offering features similar to Creality’s CR-X. Geeetech entered the market with the single-nozzle, multi-extrusion A20M printer in 2018 and has released a few more since then: the A10T, the A10M and the A20T.

Few multi-material extrusion printers are as cheap as Geeetech’s. The A20T rings in at well below the cost of a Prusa-MMU2 extruder combo and a Creality CR-X.

But, is the cheap and cheerful A20T the printer for you or should you drop more cash for a fancier multi-color printer? Read on for our review of this printer’s specs.

Multi-color printing

In most respects, this is a pretty standard printer. Where it differs significantly is here: The A20T can combine different spools of filament and extrude them from one nozzle to create multi-color prints. The color mixing is controlled using the Geeetech Color Mixer software, which lets you pick how the colors blend and other specifications.

Easy Assembly

The printer boasts a modular design that makes it easier to assemble. According to Geeetech, the build is done in three steps for minimal hassle. Its extruder even has a modularized design that is supposed to make swapping the wires in and out of your extruder a cinch.

Easy peasy. (Source: Geeetech)

Filament Detection & Print Resurrection

This is without a doubt a key feature in this printer if you want to keep your sanity. The printer alerts you when a spool is running out of filament so you can keep your multi-color prints chugging along smoothly. It also sports a print resurrection feature in case there is an unexpected stop.

Quiet Printing

The A20T has aluminum, v-shaped wheels and rails on each axis to reduce the noise the printer produces.
