Geeetech A20M Mix-Color 3D Printer

brand: SainSmart SKU: 101-91-320A Variants ID: 28624700145743

Mix-color Printing

3D fans who have used the CR-X always complained that it cannot print with mix-color, but only two independent colors, print one by one. Now, the most intriguing feature of A20M is its “mix-color” capability. That means it’s a dual extrusion printer with only one nozzle, printing two filaments in varying degrees of blending.

Large Build Volume

Featured with a relatively large build volume of 255 x 255 x 255 mm, it may not compare to the 300 x 300 x 400 mm of the CR-X, but its volume is still a space to be reckoned with.

Integrated Design

All of the electronics of A20M are housed in the base. With the all-in-one base design, the extra weight anchored to the bottom of the printer, printing will be much more stable and safe.

Resume Print & Filament Monitor Feature

If electrical power is lost, prints can be resumed from the last layer thanks to the resume print feature, saving time and reducing waste. Also, the A20M include a filament running out sensor, printing will also automatically pause when filament runs out.


As the A20M is semi-assembled, putting it together should be fun and easy. And the installation process is made even easier thanks to the modular plug-and-play cables.

Mix-color Printing

A20M, coming with Dual extruder module and 2-in-1-out hotend, provides you a printer which has a capability to print 4 types of printings with different color combinations, namely, single color, dual color, graded color and mixed color. A20M will greatly enrich your 3D printing life

3-step Fast Assembly

The Modularised Design of A20M provides you an easier assembly experience. A20M comes an integrated building base.You just need to install the upper gantry kit and filament holders on the integrated building base and then wiring.It is very simple and convenient.



Break-resuming Capability

The Break-resuming function provides A20M to save real-time printing status and resume the printing job exactly at the same place where it has been stopped. This function totally drives away the hassle of repetitive and time-time consuming printing jobs caused by unexpected power outage. Totally get you out of worries about printing large-size 3D models.


Color-Mixer Software

Color-Mixer is applicable for all mix-color printers. It allows you to print graded color between selected layers.

Optional Auto-leveling Sensor

The main board of A20M is professionally coded to support auto-leveling function. All you need is to connect the leveling sensor with it. The whole operation process is effort-saving and would greatly enhance the adhesion of the first layer.

Filament Detector

Filament detector kills the pain caused by filament outage or fracture.The detecting system would alert you to change filament in case the printer would run in air or the spool is empty. This add-on gadget would avoid bootless printing as well as enhancing your printing satisfaction.


The most intriguing feature of the A20M is its “mix-color” capability. The A20M’s menu lets you use single color g-code files and add color gradient effects or instantly change colors during the print process using the "Toggle" command, mix-color printing will greatly enrich your 3D printing life. If you are interested in CR-X but budget limited, why not trying A20M?
