Three-dimensional printer and three-dimensional printing method

Abstract

The invention provides a three-dimensional printer and a three-dimensional printing method. The three-dimensional printer comprises multiple wire wheels, a printing head, a forming base, a movable motor component and a consumable supplying motor component, wherein each wire wheel is provided with a kind of imaging material, the printing head is used for extruding the imaging material, the consumable supplying motor component comprises multiple motors, each motor is used for driving the corresponding imaging material to be transferred into the printing head, wherein a wire changing device is arranged between the consumable supplying motor component and the printing head, multiple fiber material input ends and a fiber output end are arranged on the wire changing device, the fiber material output end is connected with the printing head, and the wire changing device is communicated with a guide hole between each fiber material input end and the fiber output end. The invention also provides the three-dimensional printing method applied to the three-dimensional printer. The guide holes are used for guiding fiber materials so as to improve imaging stability, the displacement of wires is avoided, and multi-color volume rendering can also be realized through the single printing head, and the three-dimensional printer is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of three-dimensional imaging, in particular to a three-dimensional printer and a three-dimensional printing method. Background technique [0002] A 3D printer, also known as a three-dimensional printer, is a machine that uses rapid prototyping technology. Based on digital model files, it uses molding materials to construct three-dimensional entities by layer-by-layer printing. Before printing, it is necessary to use computer modeling software to model, and then "partition" the built 3D model into layer-by-layer sections, that is, slices, so as to guide the 3D printer to print layer by layer. 3D printers have been widely used in the product manufacturing industry. The working principle of 3D printers is basically the same as that of traditional printers. It consists of control components, mechanical components, print heads, consumables (that is, molding materials) and media, and the printing principles are basically si...

Problems solved by technology

However, the cost of such a printer with multiple print heads is relatively high, and multiple print heads are all arranged on a guide rod, so that the guide rod is subjected to a large force of gravity, which makes the guide rod easily deformed, resulting in low precision of the printed object , the error is large, and the multi-print head is not conducive to transportation protection, and it is easy to be damaged
