With the Geeetech A20T 3D printer, you can easily combine different filament colors. The printer accommodates three colors or types that you can alternate or combine in a single print. It is also possible to add a gradient to your design. With the Color Mixer software, mixing colors is straightforward. Additionally, with multiple extruders, you can create prints using PVA, making it easier to print complex dimensions. The modular design of the printer ensures that you can set it up in three simple steps. A filament detector signals when the filament is nearly empty, allowing you to replace it in time. Thanks to the "Resume Printing" option, a print will automatically continue after a power outage. The printer is also equipped with a reset button that restores the settings to the defaults in the G-code. The printer has a build volume of 250 x 250 x 250 mm. The V-shaped rails are made of strong aluminum, which reduces noise during printing. The printer has an accuracy of 0.1 to 0.2 mm, ensuring a fine texture for your prints. The nozzle has a diameter of 0.4 mm.
