The invention discloses a desktop-level 3D printer. The desktop-level 3D printer comprises a
machine frame, a controller, a material conveying device, an X,Y and Z axis movement device, a feeding device and a spraying
nozzle device, wherein the material conveying device and the X,Y and Z axis movement device are installed on the
machine frame; the feeding device and the spraying
nozzle device are installed on the X,Y and Z axis movement device; the material conveying device is connected with the feeding device; the feeding device is connected with the spraying
nozzle device; the controller is electrically connected with the material conveying device, the X,Y and Z axis movement device, the feeding device and the spraying nozzle device. The desktop-level 3D printer can realize effective multi-
color printing, a printed model is high in accuracy, the printing effect is good, and color switching nearly without errors can be achieved. Meanwhile, the environmental characteristic that materials like
acrylonitrile butadiene
styrene (ABS) need to be printed at a constant temperature can be realized, so that
technical support is provided for clients needing to print the ABS. The products with the biggest effective printing area are included, and requirements of various clients can be met.
