Study on Path Planning for Preparing Complex Functionally Graded Material via Extrusion 3D Printing
In order to meet the preparation process of various complex functionally graded materials,a digital design and manufacture of functionally graded material based on CT scanning grayscale images is proposed.After equalizing and denoising the CT scan grayscale image,the CT scanning grayscale image was classified into grayscale according to the set threshold and grayscale,and the grayscale values classified within the threshold were averaged.The value was then mapped to the material information,so that the formed printing contour line has material information,and the material proportion of each contour was calculated according to the set threshold and gray level,and the G-code was exported together,and then input to the 3D printer of functionally graded materials for printing.According to the extrusion type functional gradient material 3D printer,two different colors of calcium carbonate-based composite water-based paste slurry were printed and verified as an example.The results show that the present printing method can simply print the gradient change in the material information of functionally graded material model.
