3D printing aiming device for screw placement for spinal pedicle individualized screw placement provides a powerful research tool and technological breakthrough. In order to effectively suppress manufacturing error based on the FDM-3D printing for the aiming device reverse template and the guide hole tube. In this paper,through the 3D printing orthogonal experiment and regression analysis of test samples,got the FDM-3D printing process parameters optimum combination and size error correction method,on the basis for producing a reverse template attached with a good agreement with the positionin...
