Problems solved by technology

[0004] However, since 3D printing is processed layer by layer, and the 3D object has a certain thickness, after the multi-layer stacking, the cumulative moving time of the print head when returning is longer, which affects the printing efficiency

Embodiment 2

[0066] Figure 10 It is a schematic diagram of the path direction of the first printing path when the print head provided by Embodiment 2 of the present invention moves an odd number of times along the sub-scanning direction on the N slice layer. Figure 11 It is a schematic diagram of the path direction of the second printing path when the print head provided by Embodiment 2 of the present invention moves an odd number of times along the sub-scanning direction on the N slice layer. Such as Figure 10 and Figure 11 As shown, the length of the print head along the sub-scanning direction on the Nth slice layer is D, and the single movement distance of the print head in the sub-scanning direction is d, and the print head moves along the sub-scanning direction on the Nth slice layer The number of movements n in the direction, n=D / d. Taking the number of moves of the print head along the sub-scanning direction on the Nth slice layer as an example, correspondingly, the end point...

Abstract

The invention provides a 3D printing method and system. The 3D printing method of the present invention includes: step S101, printing the Nth slice layer of the object to be printed according to the first printing path, where N is a positive integer greater than or equal to 1; step S102, according to the second printing path The N+1th slice layer of the object to be printed is printed, wherein the second printing path is the reverse path of the first printing path; step S103, performing the step S101 to the step S102 in a loop, until printing is complete. The invention can realize higher printing efficiency.

Description

technical field [0001] The present invention relates to the field of 3D printing, in particular to a 3D printing method and system. Background technique [0002] 3D printing is a kind of rapid prototyping technology, because it can realize the production of models with more complex shapes, it has been more and more widely researched and applied. [0003] At present, the basic principle of 3D printing is to make 3D objects based on 3D (Three-Dimensiona) model slices and layer-by-layer processing and accumulation. Every time the print head completes the printing work of a slice layer, it is called a layer print result. The print head needs to set a starting position before the printing work starts. Each slice layer starts printing from the starting position until all slice layers are printed. . Figure 1a It is a schematic diagram of a printing path of a print head in the prior art. Figure 1b It is a schematic diagram of another printing path of the print head in the prior ...
