Three-dimensional printing control system and three-dimensional printer

Abstract

A three-dimensional printing control system comprises a processing device, a path generating device, a driving control device and a spraying nozzle control device. The processing device generates a contour line and a plurality of scanning lines, determines the first side end points and the second side end points of the scanning lines inside the contour line and determines the scanning line serving as an alarming line; the path generating device searches for the scanning lines to determine whether a current scanning line is the alarming line and determine whether the current scanning line is a filling scanning line or an auxiliary scanning line to obtain the determining results, according to the results, generates the current scanning line as a filling subpath, or generates the first side end point of the current scanning line into a filling connecting point, or generates the first side end point as a filling dividing point and generates the filling subpath and the connecting paths of all the filling connecting points of two neighboring filling subpaths into a filling path; the driving control device driving spraying nozzles to move according to the filling path; the spraying nozzle control device controls the spraying nozzles to spray out materials according to the filling path and to stop spraying according to the filling dividing points.

Description

technical field [0001] The invention relates to the printing field, and in particular to a three-dimensional printing control system and a three-dimensional printer. Background technique [0002] In the field of three-dimensional printing (3D printing) technology, the printing of the model is actually a layered manufacturing technology. After the model is analyzed, the layer data of the model is obtained, and then the inner material of the nozzle is melted by the heating nozzle at each layer of the model, and the nozzle is sprayed. Extrude the thermal fuse, obtain the current layer cross-section by filling according to the layer data of the model, and finally realize the manufacture of the model through layer-by-layer material accumulation. However, the path continuity obtained by the general filling method is low, which will lead to more empty trips. This results in a decrease in printing efficiency and a decrease in model strength.
