Problems solved by technology

[0004] However, the print head 11 of the above-mentioned three-dimensional printer melts various filaments in a plurality of print cartridges 2 and sprays the mixed consumables through the nozzles to form a three-dimensional entity. Matching and fusion, and at the same time, it is necessary to keep the melted consumables warm to prevent the solidification from clogging the discharge port, so the structure of the print head 11 is relatively complicated, and the 3D printer needs to be equipped with multiple sets of control systems to control the ingredients between different consumables. Lead to the high cost of the 3D printer
At the same time, when the printing is stopped, since the consumables are formed by high-temperature melting, it is easy to accumulate and solidify at the nozzle of the print head, and then block the print head

[0042] Reference figure 2 , figure 2 This is a structural diagram of the three-dimensional printer 3. The three-dimensional printer 3 includes four print heads 31, four switching devices 39, and a print box mounting frame 32. A plurality of print boxes 321 are installed in the print box mounting frame 32, and the print boxes 321 pass through them. The discharge port provides the consumables 322 contained therein to the print head 31. The consumables 322 can be solid filamentous consumables, and the consumables can also be powdered, liquid, etc. The structure of the print box that contains different consumables is different. Differently, this embodiment uses a printing box containing solid filamentary consumables as an example to describe the three-dimensional printer 3. Four switching devices 39 are installed on one end of the print cartridge mounting frame 32, and each switching device can be installed with a print head 31.

[0052] On the basis of the first embodiment of the three-dimensional printer 3, the three-dimensional printer 3 may also be equipped with four protection devices 4 on the guide rods 392 below the four switching devices 39, respectively. Reference Figure 7 with Figure 8 The protection device 4 includes a housing 41. A mounting hole 411 is formed through one side of the housing 41. The mounting hole 411 is sleeved in the guide rod 392 and between the housing 41 and a fixing portion 394 provided under the guide rod 392. A spring 42 is provided, and the protection device 4 is provided with a restoring force through the spring 42. The protection device 4 further includes a wiper 43, a heat preservation device 45 and a cover 44. The wiper 43 is made of elastic materials such as rubber or polyolefin, and a slit 431 is opened in the middle of the wiper 43. The heat-preserving device 45 is a spring-shaped heat-preserving device made of metal material. By energizing the heat-preservin...

Abstract

The invention provides a three-dimensional printer and a printing method of the three-dimensional printer. The three-dimensional printer comprises at least two print cartridges, a print cartridge installation rack, a movable frame, a driving head, at least two printing heads and at least two shifters. The print cartridges are installed on the print cartridge installation rack. The driving head is installed on the movable frame. Each printing head receives consumable items from the corresponding print cartridge. The printing heads are detachably connected with the driving head through first connecting devices. Each shifter is detachably connected with the corresponding printing head through a second connecting device. The printing method of the three-dimensional printer comprises the following steps: the driving head moves one printing head connected with the driving head to the corresponding shifter, each shifter is connected with the corresponding printing head, and the driving head is detached from the printing head; the driving head moves to the other printing head, the driving head is connected with the printing head, and the corresponding shifter is detached from the printing head. The three-dimensional printer and the printing method of the three-dimensional printer have the advantages that the structure is simple, control is easy, and cost is low.

Description

Technical field [0001] The invention relates to the field of printing, in particular to provide a three-dimensional printer and a printing method of the three-dimensional printer. 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 a three-dimensional entity by printing layer by layer. 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 product manufacturing. 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 (ie molding materials), and media. The printing principles are basically similar. [0003] At thi...
