[0040] like image 3 As shown, this embodiment provides a three-dimensional printer with the function of forming support materials, which includes a print head assembly 30 , a printing platform 13 , a controller 20 and a first power unit 40 .

[0041] The print head assemblies 30 move independently in three-dimensional directions with respect to the printing platform 10 , respectively. The controller 20 is electrically connected to the print head assembly 30 and the printing platform 13 respectively. In one driving mode, the controller 20 drives the motor to rotate to provide power, and the motor drives the printing platform 13 or the print head assembly 30 to move through the transmission components. The first power unit 40 is loaded with foaming agent, and the first power unit 40 supplies the foaming agent into the melting chamber 33 to mix and melt the printing material.

[0042] like Figure 4 As shown, the print head assembly 30 includes a melting chamber 33 , and the ...

[0052] The three-dimensional printer with the support material forming function of this embodiment is the same as that of the first embodiment, and only the differences will be described below. like Figure 5 As shown, the print head assembly includes a first print head 31 and a second print head 32 . The first printing head 31 is loaded with printing main material, and the first printing head 31 can move independently relative to the printing platform 13 along three-dimensional directions. The second print head 32 includes a melting chamber 33, the melting chamber 33 has a first through hole and a second through hole, and the printing support material enters the melting chamber 33 along the first through hole (side or top surface of the melting chamber), and the first power The unit delivers the blowing agent to the melting chamber 33 along the second through hole.

[0053] The first printing head 31 completes the printing steps of the main body portion 10 and the suspended...

[0059] In this embodiment, a further improvement is made on the basis of the three-dimensional printer in the first embodiment. like Figure 6 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 120 .

[0060] The printhead assembly is independently movable in three dimensions relative to the printing platform 120 . The controller 130 is directly or indirectly electrically connected to the print head assembly and the printing platform 120 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 141 , a second printhead 142 and a third printhead 143 . The first printing head 141 is loaded with a printing subject material, and the first printing head 141 can move independently in three ...

Abstract

The invention relates to a three-dimensional printer having a support material forming function. The three-dimensional printer comprises a printing head component, a printing platform and a controller, the printing head component can independently move relative to the printing platform in the three-dimensional directions; the controller is electrically connected with the printing head component and the printing platform; the printing head component comprises a fusion chamber, after being fused in the fusion chamber, a print material is deposited layer by layer on the printing platform according to the preset procedures; a first power unit is loaded with a foaming agent, and the first power unit supplies the foaming agent to the fusion chamber, so that the foaming agent is mixed and fused with the print material. When a support part is printed, the foaming agent is added into the fusion chamber, the volume of the print material expands after the foaming agent and the print material are mixed and fused, the expanded fused material is deposited layer by layer on the printing platform to form the support part, the density of the support part is correspondingly reduced, and the weight of a used support material is correspondingly reduced, so that the purpose of lowering the cost is achieved.

Description

technical field [0001] The invention relates to a three-dimensional printer, in particular to a three-dimensional printer with a support material forming function 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 main types of three-dimensional rapid prototyping methods are: 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 printing operation is more ...
