Problems solved by technology

If the uniform low-density filling method is used for layer-by-layer printing, there will be no reliable support below when the suddenly appearing closed part is printed, the printing wire will fall directly downward, and the printed object will have holes

Embodiment Construction

[0059] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.

[0060] Such as Figure 7 As shown, it is a flowchart of a three-dimensional printing method according to an embodiment of the present invention, including the following steps:

[0061] S100: Establish a mapping relationship between the support degree of each layer slice to the upper layer slice and various filling densities;

[0062] S200: Perform slice processing on the three-dimensional printing object model to obtain mult...

Abstract

The invention provides a three-dimensional printing method and system. The method comprises the steps that mapping relation between the supporting degrees of all layers of slices to upper layer slices and various packing densities is established; a three-dimensional printing object model is subjected to slicing processing, and the multiple layers of slices are obtained; the degrees of all the layers of slices supporting the upper layer slices are obtained, and the packing densities of all the layers of slices are determined according to the mapping relation; and all the layers of slices are subjected to three-dimensional printing through the determined packing densities. According to the three-dimensional printing method balancing printing supplies and the object strength, a judgment standard is added, the proper packing densities are selected according to the supporting relation of all the layers of slices and slices of the upper and lower layers, printing materials are not wasted, the printing quality can be improved, the printing time is controlled in a reasonable range, and the printing success probability is increased, so that the three-dimensional printing cost is lowered.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a three-dimensional printing method and system for improving printing quality on the basis of material saving. Background technique [0002] Three-dimensional printing technology is a printing method that uses digital model files as the basis, uses adhesive materials, and constructs objects by printing layer by layer; it can automatically and quickly materialize design ideas into prototypes with certain structures and functions Or directly manufacture parts, which can simplify the manufacturing process and produce various commodities quickly and efficiently. Therefore, three-dimensional printing has developed rapidly in recent years. [0003] In the layer-by-layer printing process, different printing effects will be obtained with different filling densities of materials. For example, when the filling density is low, the printing speed can be accelerated and printing filament ca...
