Embodiment Construction
[0027] In order to clearly describe the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, words such as "first" and "second" are used to distinguish the same or similar items with basically the same function and effect. For example, the first threshold and the second threshold are only used to distinguish different thresholds, and their sequence is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the number and execution order, and words such as "first" and "second" do not necessarily limit the difference.
[0028] It should be noted that, in the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "ex...

The invention discloses a part printing method and system, terminal equipment and a computer storage medium, relates to the technical field of three-dimensional printing, and aims to enable the arc-shaped contour of a printed part to meet the machining allowance requirement, enable machining equipment to correct the contour of the printed part conveniently and improve the precision of the part. The part printing method comprises the steps of receiving modeling information of a part; determining a laser scanning path according to the modeling information of the part; and controlling laser printing equipment according to the laser scanning path, and printing the arc-shaped contour of the part along the tangent line segment of the arc-shaped contour of the part, so that the arc-shaped contourof the part meets the machining allowance requirement. The terminal equipment is used for executing the part printing method. The part printing method provided by the invention is used for printing parts with arc-shaped contours.
Description
technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a part printing method and system, a terminal device and a computer storage medium. Background technique [0002] 3D printing technology is a technology based on digital model files, using powder-like adhesive materials to construct objects by layer-by-layer printing. Specifically, 3D printing is generally modeled by computer modeling software first, and then the built 3D model is sliced and partitioned into layer-by-layer sections, and the 3D printing equipment is guided to print layer by layer according to the laser scanning path, so as to realize rapid prototyping of objects. [0003] In the process of 3D printing, the laser scanning path directly affects the organizational structure of the processed part. However, the laser scanning path obtained by the existing filling path processing method cannot meet the filling processing requirements of parts with ...
