Integrated movement control method for 3DP pyramid printing

Abstract

The invention relates to an integrated movement control method for 3DP pyramid printing. The method comprises the following steps that firstly, a CLI slice file is analyzed, and a data model of a 3D printing model is built; secondly, the data model is loaded according to layers, each layer presents a sectional view of the 3D printing model, polylines in each layer of outline are divided and regrouped according to given parameters, the sectional view of each layer is divided into several different sectional split graphs in the same direction, and the data of the split graphs form new layer data models; thirdly, the new layer split sectional data are analyzed, and position coordinates of printing areas of all the split sections are built; and fourthly, the new layer data are processed, BMP bitmaps are generated, new layer information circulates, BMP bitmap data are loaded, and a printing head is driven to reach the starting point of the printing areas of the split sections to start printing. The method has the beneficial effects that the flexible and effective sheet division method can effectively remove the part without graphs, only the part needing printing is reserved, and a spraying head can conduct rapid movement and efficient printing as needed.

Description

technical field [0001] The invention relates to a control method used in 3D printing, in particular to an integrated motion control method for 3DP pyramid printing, which belongs to the field of mechanical automation printing. Background technique [0002] Inkjet sticky powder (3DP) 3D printing technology is that the nozzle is controlled by the computer, operates according to the two-dimensional data of the model section, and selectively sprays the binder at the corresponding position to finally form the layer. After each layer is bonded, the forming cylinder is lowered by a distance equal to the thickness of the layer, the powder supply cylinder is raised to a certain height, and the excess powder is pushed out by the powder spreading roller to the forming cylinder, paved and then compacted; in this cycle, Until the bonding of the entire object is completed. During this process, the cross-section of each layer of the two-dimensional data model is formed, and the size of th...

Problems solved by technology

The printing control system loads the entire image frame and uses the entire image frame as the printing area, which cannot effectively control the rapid movement of the nozzle in the part without image, and only sprays at the corresponding injection position, which seriously affects the printing efficiency
