Problems solved by technology

[0005] In the actual printing process, for the 3D object model with suspended parts, due to the problem of the viscous properties of the material, the existing 3D printing method cannot normally support and print the entire model, that is, it is not printable; therefore, for the non-printable parts need Add extra support to 3D object models to ensure printability

Embodiment Construction

[0044] In the process of 3D printing, since 3D printing is printed layer by layer from bottom to top, for a newly printed layer, it will be supported by the layer below it. When the 3D printer prints to a certain point, if there is a printed solid point directly below the point, then the point can be supported by the solid point directly below and can be successfully printed; if the point directly below If there is no solid point, but there is a solid point obliquely below the point, whether the point can be supported by the solid point obliquely below depends on the viscous characteristics of the printing material and the tilt parameters.

[0045]According to the above-mentioned working principle of 3D printing, in the process of realizing the application, by assigning a support parameter to each node on the 3D mesh model of the object to measure the support stability of the node, the support of the node on the 3D mesh model The parameter value is generated by passing the sup...

Abstract

The invention discloses a printability acquisition method and system for three-dimensional printing. The printability acquisition method comprises the following steps: acquiring a three-dimensional grid model of a to-be-printed object, acquiring a supporting parameter value of any node on the three-dimensional grid model, and acquiring the printability of the node according to a preset critical parameter value and the supporting parameter value. The printability acquisition method and system disclosed by the invention has the advantages that one supporting parameter is endowed for each node on the three-dimensional grid model of the to-be-printed object and is used for balancing the supporting stability of the nodes, the supporting parameter values of all the nodes on the three-dimensional grid model are acquired according to an energy transfer idea, and whether the nodes have the printability is judged according to the relation between the preset printing critical value and the acquired supporting parameter values, so that the printability of the three-dimensional printing system can be accurately acquired.

Description

technical field [0001] The present invention relates to the technical field of three-dimensional printing, in particular to a method and system for obtaining printability of three-dimensional printing. Background technique [0002] Three-dimensional printing is a kind of rapid prototyping technology. It is based on digital model files and uses liquid, powder or sheet metal, plastic and other materials to construct objects by printing layer by layer from bottom to top. Technology. [0003] 3D printing is usually realized by using digital technology material printers. It is often used to manufacture models in the fields of mold manufacturing and industrial design. Later, it is gradually used in the direct manufacture of some products. Currently, it has been printed using this 3D printing technology. parts. 3D printing technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medica...
