Embodiment Construction

[0061] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0062] Such as Figure 4 The illustrated embodiment is a scanning path sorting method for stereolithography rapid prototyping of 3D printing, comprising the following steps:

[0063] Step 100, establish a two-dimensional array of each scan line segment according to the obtained scan line segment:

[0064] Input the contour of the object into the computer in advance, and use horizontal grid cutting to obtain such as figure 1 For all the scanning line segments arranged in sequence along the vertical direction, the following calculation process is carried out in the computer:

[0065] Set the data structure of each scan line segment as SEGMENT, and SEGMENT includes the attribute Point representing the left end point of the scan line segment, the attribute OtherPoint representing the right end point of the scan line segment, and the attribute BIn...

Abstract

The invention discloses a stereo lithography rapid moulding scanning-path ordering method for 3D printing. The method is characterized in that all the scanning line segments are partitioned with a least travel principle, each block comprises the scanning segments as much as possible, after partitioning, all the blocks are ordered, so that high efficiency ordering for the scanning segments can be realized. According to the invention, the path ordering with partitioning can reduce the travel distance and increase the scan efficiency; the path ordering with partitioning can realize high integration degree of the scanning path, printing continuous degree is high, and moulding intensity can be enhanced.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a scanning path sorting method for stereolithography rapid prototyping of 3D printing that can effectively improve scanning efficiency. Background technique [0002] In the field of 3D printing (rapid prototyping) technology, the SLA (Stereo Lithography Apparatus) process is a layered manufacturing technology. The computer controls the laser beam to scan the surface of the photosensitive resin as the raw material, and the thin layer of resin in the scanned area produces photopolymerization. Reacts to cure, forming a thin layer of the part. The workbench is moved down by a layer thickness, so that a new layer of liquid resin can be applied on the surface of the cured resin, and the scanning process of the next layer is carried out, and so on, until the entire prototype is manufactured. [0003] The work of SLA is mainly to scan the photosensitive resin material, and the scann...
