Embodiment Construction

[0019] A kind of 3D printing method of medical model, comprises the following steps:

[0020] A. Obtain 3D model data, import the model into the magics software through the STL file provided by the customer to fix the position of all model parts, output the file in STL format, and then import it into the 3Dmax software for model modification and cutting;

[0021] B. According to the current situation of the model organ, set the cutting line along the maximum boundary of the three-dimensional coordinates of each organ after mutation, and export the STL files for the cut and divided parts; when setting each cutting plane, the cutting plane passes through the outer wall of each organ and the main body The center point of the intersecting surface of arteries and veins;

[0022] C. Save the saved STL file into the Cura software, output the print file in gcode format and start printing;

[0023] Printing consists of the following steps,

[0024] C1. Store all models in SD card;

Abstract

The invention discloses a 3D printing method for a medical model. The 3D printing method comprises the steps that A, three-dimensional model data are acquired, the model is imported into magics software through a STL file provided by a client so as to fix the positions of all parts of the model, and the output file with the STL format is then imported into 3DMAX software so as to modify and cut the model; B, according to the current situations of organs of the model, section lines are set along the maximum boundary of three-dimensional coordinates of all the organs after variation, and parts which are are sectioned and cut are exported to be STL files respectively; and C, the stored STL files are stored into Cura software, print files with the gcode format are output, and printing is started. The method has the advantages that the defects in the prior art can be overcome, and the precision of the 3D printed organ model can be improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing method of a medical model. Background technique [0002] Human organ models are the main means for medical teaching and clinical medical assistance. At present, the human body model manufactured by the mold process cannot simulate the blood flow, blood pressure change, and body temperature change inside the organ, that is, the current human body model is only observational, not functional. Due to the inherent characteristics of the existing technology, users can only observe the anatomical structure of human organs, it is difficult to use the current observation-type mannequin for anatomical operations, and the anatomical operability and authenticity are greatly reduced; moreover, clinicians encounter difficulties For cases, it is necessary to prepare sufficient surgical plans and pre-plans before the operation, and the current observation-type mannequin cannot...
