[0033] Such as image 3 As shown, it is a three-dimensional printer with a support material printing head provided in this embodiment, and the three-dimensional printer includes a printing head assembly and a printing platform 20 .

[0034] The printhead assembly is independently movable in three dimensions relative to the print platform 20 . The controller 30 is directly or indirectly electrically connected with the print head assembly and the printing platform 20 respectively, and the controller can be a single-chip microcomputer or a chip processor or a computer or a PLC (programmable logic controller) program. The printhead assembly includes a first printhead 41 , a second printhead 42 and a third printhead 43 . The first printing head 41 is loaded with a printing subject material, and the first printing head 41 can move independently in three dimensions relative to the printing platform 20 . The second printing head 42 is loaded with a printing support material, and the...

[0044] This embodiment is basically the same as the above-mentioned first embodiment, and only the differences will be described in detail below.

[0045] The density of the support part 12 in this embodiment is lower than that of the main part 10, and the density can be determined according to the specific printing method. The print head extrudes a strip of molten filamentary printing material on the support plate 50, and the horizontal filamentary material and Longitudinal filamentary materials overlap and intersect to form a three-dimensional object with a layered structure. The main body part 10 generally requires a higher-density structure, while the support part 12 can be printed to form a loose and lower-density structure because it is only for temporary support. After the three-dimensional object is formed, the supporting part 12 needs to be removed. The density of the main body portion 10 is the same as that of the suspended portion 11 .

[0049] The three-dimensional printer of this embodiment is basically the same as the first embodiment, and the support plate of the first embodiment can be applied to the three-dimensional printer of this embodiment. And, on this basis, further improvements are made in this embodiment. Such as Figure 7 As shown, this embodiment provides a three-dimensional printer, which includes a print head assembly 130 , a printing platform 113 , a controller 120 and a first power unit 140 .

[0050] The printhead assemblies 130 move independently in three-dimensional directions relative to the printing platform 110 , respectively. The controller 120 is electrically connected to the print head assembly 130 and the printing platform 113 respectively. In one driving mode, the controller 120 drives the motor to rotate to provide power, and the motor drives the printing platform 113 or the print head assembly 130 to move through the transmission components. The first power unit 140 is loade...

Abstract

The invention relates to a three-dimensional printer with a support material printing head. The three-dimensional printer includes a printing head assembly and a printing platform, and the printing head assembly can move independently in three dimensions relative to the printing platform; a controller is electrically connected to the printing head assembly and the printing platform respectively. Connection; the print head assembly includes a first print head and a second print head, the first print head is loaded with a print body material, and the first print head can move independently in three dimensions relative to the printing platform; the second print head is loaded with a print support material , the second printing head can move independently relative to the printing platform in three-dimensional direction; the support plate assembly has a moving mechanism and a supporting plate connected together, and the moving mechanism drives the supporting plate to move in three-dimensional direction relative to the printing platform. Before printing the support part, the support plate is moved to the second height above the printing platform, and the second printing head deposits the support material on the support plate to form the support part, which can shorten the required printing height of the support part.

Description

technical field [0001] The invention relates to a forming device and a forming method, in particular to a three-dimensional printer with a support material printing head and a forming method thereof. Background technique [0002] Three-dimensional printing, also known as additive manufacturing or layered modeling, is the process of using a digital model to process a physical object. During the processing, the printed object is built by adding materials layer by layer. [0003] The methods of three-dimensional rapid prototyping mainly include the following types: stereolithography or photocuring (Stereolithography, SLA), layered object manufacturing (Laminated object manufacturing, LOM), selective laser melting (Selective laser Melting, SLM), fused deposition modeling (Fused deposition modeling, FDM). [0004] Currently, three-dimensional (3D) printing of the FDM type is the most common on the market. The production cost of this type of 3D printer is relatively low, and the ...
