Problems solved by technology

If the height of the sealed shell itself is smaller than the height of the object to be printed, there will still be delamination and deformation around the part of the object to be printed that is higher than the sealed shell because there is no heat preservation effect of the sealed shell, which will affect the molding effect.
If the customized sealed shell itself is very high, or can be spliced ​​freely, although its thermal insulation function can be guaranteed, there are problems of high cost and inconvenient splicing

Embodiment 1

[0029] Such as figure 1 , figure 2 , image 3 As shown, the three-dimensional printer 100 provided by the present invention includes a printing platform 101, a printing head 102 arranged above the printing platform 101, a forming base 104 fixed on the printing platform 101 and carrying a three-dimensional printing entity 103, and an edge perpendicular to the printing platform 101 A guide rail 105 is arranged in a direction, a heat preservation component 108 is arranged around the printing platform 101, and a heating device 109 is arranged under the printing platform 101. The heat preservation component 108 is made of stretchable elastic material, such as high temperature resistant polyester film (PET film), high temperature resistant polypropylene film (PP film), etc. The upper end is connected with the fixed frame 106 of the printing platform 101, The lower end is sleeved on the forming seat 104. The heat preservation component 108 is connected to the guide rail 105 so that t...

Embodiment 2

[0032] Such as Figure 4 , Figure 5 As shown, preferably, the thermal insulation component 208 of the three-dimensional printer 200 may be a double-layer inflatable device, and a side facing the three-dimensional printing entity 203 is provided with a plurality of small holes (not shown). During printing, hot air is charged between the two layers of the thermal insulation component 208, so that the inflated thermal insulation component 208 slowly expands and rises in a direction substantially perpendicular to the molding seat, and always maintains a certain distance from the three-dimensional printing entity 203. Under the continuous action of the fan 207, the hot air generated by the heating device under the printing platform 201 is transferred to the space enclosed by the printing platform 201 and the heat preservation component 208, and forms a circulation in the space.

[0033] The present invention provides a printing method for a three-dimensional printer, which uses the t...

Abstract

The invention provides a three-dimensional printer and a printing method of the three-dimensional printer. The three-dimensional printer comprises a printing platform, a printing head arranged above the printing platform, a forming base fixed onto the printing platform and used for bearing a three-dimensional printing entity, and guide rails arranged in the direction perpendicular to the printing platform, wherein a heating device is arranged below the printing platform; a heat insulation component is arranged on the periphery of the printing platform and is made of stretchable elastic materials. By means of the three-dimensional printer and the printing method of the three-dimensional printer, it is effectively ensured that a printed object is maintained within a temperature range, the changes of temperature between layers are not large, and the printing quality is ensured; the heat insulation component is simple in structure and low in cost; the height of the heat insulation component can be adjusted anytime according to the actual printing conditions, and the problems that a heat insulation component made of a rigid material is poor in adaptability and high in cost are solved.

Description

Technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a three-dimensional printer and a printing method thereof. Background technique [0002] Three-dimensional printing, also known as 3D printing, is a kind of rapid prototyping technology. It is a technology that builds objects based on digital model files, using molding materials, and stacking them layer by layer. In the past, 3D printing was often used to make models in mold manufacturing, industrial design and other fields, and it is now gradually being used in the direct manufacturing of some products. The process of 3D printing is first to model by computer-aided design (CAD) or computer animation modeling software, and then "partition" the built 3D model into layered sections, and then obtain the processing path based on the analyzed section information, thereby guiding the printer step by step Layer printing. [0003] As a typical representative of three-dimens...
