Problems solved by technology

[0004] However, the above-mentioned printing heads for spraying are mostly composed of gear sets, pipes, nozzles and other components, so the melted or softened molding materials are easy to stay in the gaps of the aforementioned components. The residual material here is easy to affect the normal operation of subsequent components

Embodiment Construction

[0041] figure 1 It is a schematic diagram of a three-dimensional printing device according to an embodiment of the present invention. figure 2 yes figure 1 Schematic diagram of some components of the three-dimensional printing device. Please refer to figure 1 and figure 2 , in this embodiment, the three-dimensional printing device 100 is suitable for printing a three-dimensional object 20 according to a digital three-dimensional model information, which includes a control unit 110 , a base 120 and a printing component 130 . In this embodiment, the digital three-dimensional model information may be a digital three-dimensional image file, which is constructed by a host computer through computer-aided design (CAD for short) or animation modeling software, for example. The control unit 110 can be used to read and process the digital three-dimensional model information and then drive the printing unit 130 to three-dimensionally print the three-dimensional object 20 layer by l...

Abstract

A 3-D printing apparatus is configured to make a modeling material form a 3-D object layer by layer. The 3-D printing apparatus includes a printing assembly and a cleaning unit. The printing assembly includes a feeding tube, a nozzle and a driving wheel set disposed between the feeding tube and the nozzle to drive the modeling material transferred to the nozzle from the feeding tube and then exiting from the printing assembly via the nozzle so as to form a 3-D object layer by layer. The cleaning unit has a brush, in which the brush leans against on the driving wheel set to clean out the residual modeling material while the driving wheel set rotates relatively to the cleaning unit.

Description

technical field [0001] The present invention relates to a printing device, and in particular to a three-dimensional printing device. Background technique [0002] With the advancement of Computer-Aided Manufacturing (CAM), the manufacturing industry has developed three-dimensional printing technology, which can quickly produce the original design idea. Three-dimensional printing technology is actually a general term for a series of Rapid Prototyping (RP) technologies. Discontinuously displace the layer thickness at the Z coordinate, and finally form a three-dimensional object. Three-dimensional printing technology can have unlimited geometric shapes, and the more complex parts are, the more superior the RP technology is, which can greatly save manpower and processing time. Under the shortest time requirement, 3D computer-aided design (Computer-Aided Design, Abbreviation: CAD) software designed digital three-dimensional model information is truly presented, not only can be ...
