step 11, after printing is finished, cleaning the guide plate by using a model cleaning solution, drying in the air, removing redundant supports, and polishing corners by using abrasive paper;
and step 12, finishing printing.
7. The guide plate preparation method of the 3D cloud platform multi-plate guide plate fabrication data management system according to claim 6, wherein the joint guide plate fabrication step process comprises:
step 1, importing CT data into MIMICS software:
after software MIMICS is opened, a FILE key at the upper left corner is selected, then NEW Project is clicked to select a folder for storing DICOM data, the DICOM data required by research can be selected as the DICOM data are fault data, NEXT entering is clicked, the direction of a data transmission model is confirmed, and OPEN entering is clicked;
step 2, carrying out DICOM data segmentation reconstruction:
clicking the SEGMENT area at the upper left corner in MIMICS software, selecting NEWMask, adjusting the size of the threshold value by pulling left and right, and selecting the threshold value to click OK to complete the process. Clicking the skin just created in the Masks function, clicking Calculate Part on the right button to enter a model generation plate, and clicking Calculate to generate;
using an editmasks tool in the segmentation column to modify skin files in a layered mode, using three options of Draw \ Erase \ Threshold to finish the separation of bones to be printed from surrounding hard tissues, clicking the separated bones by a regiongrow tool in the segmentation column to generate a new skin file, finishing the three-dimensional reconstruction operation again, and generating a new digital model;
step 3, manufacturing a guide plate:
according to the operation requirement and preoperative medical examination and clinical examination, designing a hole site line meeting the operation requirement, and separating a part needing to be punched;
selecting a coverage area as a working surface by using a mouse, then selecting the working surface to generate a surface entity, thickening the thickness of the surface entity, then carrying out Boolean difference calculation with the mandible to obtain a guide plate tightly attached to the surface of the mandible, adding required hole sites by using a cylindrical function according to the operation requirement, and correspondingly cutting the guide plate until the operation requirement is met;
and 4, slicing the model:
and (3) outputting the STL file:
after the guide plate is manufactured, clicking an STL tool of an export column, checking a model needing to be output, selecting a position for storing a file in an outputdigirector, and storing the file in a target folder;
importing the STL file into Magics software, and repairing the printing model by using a model repairing function to prevent printing failure caused by the problems of bad edges, overlapped triangular patches and the like;
STL file input:
the STL file is loaded into and unloaded from the Cura 15.04.6 software, and the spatial position, scale size, rotation direction, and support data of the print model are set. By adjusting the position and selecting a proper position, the forming precision can be improved, the model precision is ensured, and the size of the model is kept unchanged; material can also be saved. In the printing process, the XY direction precision is higher, the Z direction precision is poorer, and the required surface is ensured to be high precision through rotation, so that the printing precision is improved. The printing model needs to be added with necessary support, so that the printing mechanical support is met, and the printing failure is prevented;
and clicking Save toolpath to slice layer by layer, and then selecting a proper folder to store (GCODE) data.
And step 5, model printing: storing (GCODE) data in a U disk, guiding the data into 3D printing equipment by using the U disk for printing, and finishing printing;
step 5, forming a real object: and (4) removing the product support after printing is finished, then cleaning with alcohol, finishing cleaning and sterilizing.
8. The guide plate preparation method of the 3D cloud platform multi-plate guide plate fabrication data management system according to claim 6, wherein the guide plate multi-plate fabrication step process comprises:
and selecting a plurality of data module plates, importing the data module plates into a system according to basic data detected by a doctor, and selecting to simultaneously perform 3D printing and manufacture a real object guide plate.
9. The method for preparing a guide plate of a 3D cloud platform multi-plate guide plate manufacturing data management system according to claim 8, wherein the plurality of data module plates are ischial osteotomy guide plate data modules, sacrum osteotomy guide plate data modules, ilium osteotomy guide plate data modules, femur osteotomy guide plate data modules and/or pubic osteotomy guide plate data modules, and are imported into the system according to basic data detected by a doctor to select simultaneous 3D printing and manufacturing of a real object guide plate.
10. The method for preparing the guide plate of the 3D cloud platform multi-plate guide plate manufacturing data management system according to claim 5 or 6, wherein a titanium alloy cylinder for development is fixedly connected to the edge of the guide plate.
