Never one to sit on its hands, Geeetech are at it again. Busting out of the stands after the recent launch of the Geeetech A20M follows up an even more impressive stablemate. And he has brought his little brother along too…Introducing the Geeetech A10T and A20T.
Little A10T
Designed to appeal to the more compact end of the market, the Geeetech A10T has a build volume of 220mm*220mm*250mm. The Geeetech A10T and A20T extruder motors use a gear train of 3:1 ratio, so as a result, it multiplies the input torque similar to a titan style extruder which should prove to be a benefit when using softer filaments such as TPU. At the same time, Geeetech has also incorporated a filament detector and break-resuming capability within the firmware saving on lost prints.
Straight away you notice the three extruders mounted on the top cross member! As a result, we are expected to have the filament behind the printer. This may work for some, although personally, it wouldn’t work for my set up. The reason being is there is no room behind them, although I don’t see any alternative placement.
Large A20T
The Geeetech A20T is the big brother to its smaller sibling, therefore, sharing the same features, but with a larger build volume of 250*250*250. Also, a little more thought appears to have gone into the design here with the mainboard cooling fan intake being located under the unit as opposed to the top like the A10T.
Colour mixer – or should that be Color mixer?
Above all, Geeetech has incorporated its software to control the mixing of the colours, named Color Mixer. It uses the layer height to determine the right place to change in the position of the print.

Geeetech A10T and A20T My Thoughts
Above all, I like the concept building on the already successful A10M, and A20M geometry is a smart move for Geeetech.
However, while I am a little dubious of the 3 in one hot end, I can imagine the need for a purge block as a necessity for more precise colour changes. As a result, I do like the way they have got around the lack of space by mounting the extruders on the top rail and using the 3.1 ratios to allow for better control,
Besides, the incorporation of filament run-out sensors is a great idea. Hopefully, the firmware is sufficiently set up to allow for thermal runaway protection. Judging from Geeetechs previous offerings, I would imagine it is, however without a test machine. I cannot confirm this. Short of the significant investment in something like, for instance, a mosaic pallet this is the closest most home users will get to actual multi-colour printing.
Final Thoughts
To sum up, I’m not sure it is for me. I like the concept, but I think I would be more inclined to spend my money on a mosaic pallet, but that is my personal opinion. I’m sure once someone gets a physical printer to test, they will be able to show the brilliance Geeetech usually bring to their innovations.
