  • Patent number: 12365143
    Abstract: Embodiments of the present disclosure provide three-dimensional (3D) printing methods, systems, and devices for target objects, and relate to a field of image data processing technology. The method includes performing a layering process to a 3D model of a target object and designing a printing path sequence, after each layer of the print is completed, according to a current layer 3D model and point cloud data of a single-layer 3D model corresponding to the current layer 3D model, performing the inspection of a height difference, a horizontal dimension difference and a void region in the printing, and according to the inspection result, performing timely feedback and adjustment, which can not only improve the professionalism, stability and efficiency of the printing, but also improve the similarity between the printed physical object and the target object, resulting in achieving a more accurate 3D printing.

  • Patent number: 10486412
    Abstract: A 3D bio-printer capable of detecting cell activity is provided. The 3D bio-printer includes an upper PC and a lower 3D printer. A conveying hose is connected to a printhead base of the printer, and a temperature controller is connected to the conveying hose. A printhead controller is connected to the other end of the conveying hose, a printhead is connected to the bottom of the printhead controller, and a main control cabinet controls the printhead to work via a signal generator. A prototyping table is provided under the printhead and is connected with a cell activity detecting device for detecting activity of a printed product. Cell activity can be detected in the process of printing, which ensures that the printed biological tissues maintain biological activity. It can supply multi-biological raw materials and realize multi-biological material printing, which ensures an environment suitable for biological material printing.
