Embodiment 1

[0031] refer to figure 1 As shown, the 3D array inkjet printing defect detection and correction system provided by the present invention includes: a 3D printing module, a height scanning module, an image scanning module and a control module.

[0032] The 3D printing module, the height scanning module, the image scanning module are electrically connected with the control module. Further, the control module includes an upper computer and a lower computer, the upper computer is electrically connected to the lower computer, the lower computer is electrically connected to the 3D printing module, the height scanning module, and the image scanning module, and the upper computer is connected to the 3D printing module, the height scanning module, and the image scanning module. Realize data transmission through the lower computer. Wherein, the upper computer is a kind of in computer, industrial computer, preferably upper computer is computer, and upper computer is integrated with infor...

Embodiment 2

[0038] The 3D array inkjet printing defect detection and correction method based on the system of embodiment 1 comprises the following steps:

[0039] S1. The 3D printing module receives the printing instruction from the control module and executes the printing of the slice layer.

[0040] S2. The height scanning module receives the scanning instruction from the control module to scan each pixel of the slice layer printed by the 3D printing module, and uploads the scanned height information to the control module.

[0041]S3. The control module converts the received height information into an actual height value and subtracts it from the preset theoretical height value to calculate the missing value of the actual height of each pixel, and compares the calculated missing value of the actual height of each pixel with the Compared with the preset height missing threshold value, when the actual height missing value of each pixel in the comparison result is less than the height miss...

Abstract

The invention discloses a 3D array inkjet printing defect detection and correction system and method. The system comprises a 3D printing module, a height scanning module, an image scanning module and a control module; the 3D printing module, the height scanning module and the image scanning module are electrically connected with the control module; the 3D printing module is used for printing of a slice layer; the height scanning module is used for scanning height information of the slice layer and uploading the height information to the control module; the image scanning module is used for scanning image information of the slice layer and uploading the image information to the control module; the control module is used for processing the height information and the image information and working out whether the slice layer has a printing defect or not; and if the printing defect is present, a repair printing instruction is automatically generated and the 3D printing module is controlled to execute the repair printing instruction for printing; By adopting the technical scheme, under the condition that a jet orifice of the 3D printing module is blocked, printing can also be implemented, so that the printing efficiency is guaranteed, the service life of the 3D printing module is prolonged, and the cost of an enterprise is reduced.

Description

technical field [0001] The invention relates to the technical field related to 3D printing, in particular to a 3D array inkjet printing defect detection and correction system, and also to a 3D array inkjet printing defect detection and correction method. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files, using powdered metal or plastic and other bondable materials to construct by layer-by-layer printing. technology of objects. [0003] The 3D array nozzle components are consumable parts. After a certain period of use, individual nozzle holes will be blocked, and the entire 3D array nozzle needs to be disassembled and replaced, which not only affects the service life of the 3D array nozzle, increases the cost of the enterprise, but also affects printing efficiency. Contents of the invention [0004] In order to overcome the existing technical defects and solve...
