Problems solved by technology

3D printers using wire materials generally use monochrome printing. If you want to print in multiple colors, you need to constantly replace the wires, which is very troublesome.
At the same time, the printing speed of the 3D printer is relatively slow. If the printing speed is increased, the printing head will be overheated, the product will be deformed, and even collapse.

Embodiment Construction

[0023] The present invention will be further elaborated below in conjunction with the accompanying drawings of the description.

[0024] The structure of a kind of 3D printer of the present invention is as figure 2 As shown, a screw feeding mechanism is set in the printing head of the printer, including a driving device 5, a screw 2 connected to the output shaft of the driving device 5, and a screw barrel 3, wherein the screw 2 is arranged inside the screw barrel 3, and the driving device 5 Installed on the outer end of the screw barrel 3, the feed end of the screw 2 is connected to the discharge port of a hopper 6, the discharge end of the screw 2 is connected to the print head nozzle 1, and the electric heating ring 4 is arranged outside the screw barrel 2.

[0025] The present invention uses a spiral propulsion method to transport the printing material to the nozzle 1 of the print head. Such a structural setting does not limit the wire form of the printing material, but ca...

Abstract

The invention relates to 3D printer equipment. A screw feeding mechanism is arranged in a printing head of a printer; the 3D printer equipment comprises a drive device, a screw connected with an output shaft of the drive device and a screw barrel, wherein the screw is arranged inside the screw barrel; the drive device is mounted at one end of the outer part of the screw barrel; the feeding end of the screw is connected with a discharge hole of a hopper; the discharging end of the screw is connected with a printing head spray nozzle; and an electric heating ring is arranged on the outer part of the screw barrel. The 3D printer equipment changes the working mode of an existing plastic high-molecular 3D printer without using a pre-prepared linear plastic high-molecular material while only a granular or powdered thermoplastic high-molecular material is needed; and moreover, a colorant can be mixed while the material is added, so that a colorful 3D printing function is realized.

Description

technical field [0001] The invention relates to a 3D printer device. Background technique [0002] 3D printer, also known as three-dimensional printer, is a kind of cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials. Print layers of adhesive material to create three-dimensional objects. At present, 3D printing technology is divided into the following printing materials or printing methods: [0003] 1. Some 3D printers use the "inkjet" method. A very thin layer of liquid plastic substance is sprayed onto the casting tray using the printer's print head, and this coating is then exposed to ultraviolet light for treatment. The mold tray is then lowered a very small distance for the next layer to be stacked up. [0004] 2. Using a technology called "fusion deposition molding", the whole process is to melt the plastic in the print...
