Product description

Discover the A20 3D printer by Geeetech. With an accuracy of 0.1 mm you can expect to capture the full detail of a 3D model while achieving a nice smooth surface. Create high quality 3D prints and realistic prototypes for art and engineering purposes. Start 3D printing right with a quick 2-step assembly!

The Geeetech 3D printer has a dual-Z axis that provides great stability and accuracy, ensuring high quality 3D prints. This is also supported by the excellent 360°C ventilation feature in place to increase heat dissipation. Equipped with V-shaped wheels and rails will not only ensure wear resistance but also highly reduce printing sounds and offer a quiet printing experience. Install a leveling sensor like the BL-touch to make use of accurate auto-bed leveling. This will save time on configuration and significantly boost printing precision.

The 3D printer also has an open source firmware so that you have multiple upgrade and growth options. Furthemore, you will receive the Repetier-Host software. The machine has been fitted with a filament sensor that will alert you when filament is running out so that you can replace the spool to avoid any failed prints. Furthermore the break-resuming feature conveniently allows you to resume 3D printing in case of a power outage, with a swift click of a button. The Geeetech A20 Pro has a build volume of 250 x 250 x 250 with a full 360°C view so that you can monitor and glance at your model being printed!

3D printer properties

The maximum volume what can be 3D printed with this machine. This normally is almost the size of the printbed times the height the head can be above the bed.

25x25x25 cm
Printer Geometry Cartesian
Nozzle diameter 0.4 mm
Filament types 312,313,311
Filament diameter 1.75 mm
Max. hot-end temperature 250 °C
Extruder type

Bowden printers feed filament through a tube as opposed to Direct Drive systems. This adds important advantages (faster printing) and disadvantages (higher filament retraction settings). You can find more information on Direct Drive and Bowden systems, Click here

Max. heated bed. temp. 100 °C
Type of 3D printer FDM/FFF
Bed movement direction

The direction the buildplate moves. Most printers move the build plate in the Y-axis direction. This is a simpler design, but gives problems at greater build height, because the inertia of the mass of the buildplate + 3D print impact the quality of the layers, requiring you to limit the speed. Other printers move in the Z-axis, allowing you to print faster without trading quality of the layer build-up.

Product Dimensions 442x447x480 mm
