Embodiment Construction
[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a three-dimensional object manufacturing method. The three-dimensional object manufacturing method comprises the following steps of (1) coating an outer contour material ontothe cross section contour boundary of the current layer of a three-dimensional object to be manufactured and coating a molding material in a cross section contour area of the current layer of the three-dimensional object to be manufactured to make the outer contour material encircle the three-dimensional object to be manufactured and correspond to the cross section contour of the molding material;(2) heating the molding material coated onto the current layer and at least one layer of molding material coated onto the current layer into a molten state; and (3) repeating the steps (1) and (2) until manufacturing of the three-dimensional object is completed, wherein the melting point of the outer contour material is higher than the melting point of the molding material. According to the three-dimensional object manufacturing method, in the printing process, the molding material coated onto the current layer and the previous at least one layer of molding material of the current layer are better fused and bonded, so that printing layers are combined more completely. The invention further provides a three-dimensional object manufacturing device.
Description
technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a three-dimensional object manufacturing method and three-dimensional object manufacturing equipment using FDM technology. Background technique [0002] 3D printing is a rapid and precise additive manufacturing technology, which is different from the traditional subtractive manufacturing technology. It is based on digital information technology and is a high-tech multi-disciplinary comprehensive application. Through 3D printing technology, any data model can be formed layer by layer in the printer, and quickly and accurately transformed into physical parts. Because of its precise and fast manufacturing characteristics, it has been widely used in the fields of prototype conception and design verification. At the same time , also provides a new direction for personalized manufacturing. [0003] Fused Deposition Modeling (FDM), also known as fused filament deposition...
