Three-dimensional printing device and printing error correcting method thereof

Abstract

The invention provides a three-dimensional printing device and a printing error correcting method thereof. A printing head of the three-dimensional printing device is suitable for moving on a datum plane along at least one linear printing path, and a formed material is fed out at the same time so that all laminated articles can be formed on a bearing surface of a platform. If the path distance of the linear printing path is larger than a threshold value, a first compensation value of the starting node and a second compensation value of the ending node are calculated according to the linear compensation relation corresponding to a plurality of first class areas of the bearing surface. If the path distance of the linear printing path is not larger than the threshold value, a common compensation value is determined according to at least one of a plurality of second class areas corresponding to the starting node and the ending node. According to the three-dimensional printing device and the printing error correcting method thereof, the printing heights of all printing nodes can be further adjusted according to the actual state of the platform, and thus the printing quality is effectively improved.

Description

technical field [0001] The present invention relates to a printing device, and in particular to a three-dimensional printing device and its printing error correction method. Background technique [0002] With the advancement of Computer-Aided Manufacturing (CAM), the manufacturing industry has developed three-dimensional printing technology, which can quickly produce the original design concept. Three-dimensional printing technology is actually a general term for a series of Rapid Prototyping (RP) technologies. Discontinuously displace the layer thickness at the Z coordinate, and finally form a three-dimensional object. Three-dimensional printing technology can have unlimited geometric shapes, and the more complex the parts, the more the excellence of RP technology can be shown, and it can also greatly save manpower and processing time. Under the shortest time requirement, 3D computer-aided design (Computer-Aided Design, The digital three-dimensional model designed by CAD)...

AI Technical Summary

Problems solved by technology

However, due to errors in mechanical components or limited process technology, the platform used to carry the substrate in the three-dimensional printing device may be tilted or the surface may be uneven.

When the platform is tilted or its surface is uneven, since the printing head of the three-dimensional device still stacks the substrate on the platform according to the printing coordinates relative to the horizontal plane, the printed three-dimensional object will have a drop from the actual expectation, thus reducing the Printing quality and printing yield of three-dimensional printing device
