3D printing technology, with the development of science and technology, the application in the field of clothing can not be counted. In this paper, based on the design technology route of 3D printing clothing, we first establish parametric 3D three-dimensional clothing. After determining the constraints of the clothing curve, we generate the clothing parametric surface by interpolation and then adjust the horizontal mesh to generate the three-dimensional clothing model. The Gragh Cut algorithm is used to segment the garment image and extract the 3D garment contour features. Finally, the exploration of the aesthetic implication and modeling characteristics of 3D printed garments is launched, and examples analyze the aesthetic characteristics and comfort of 3D printed garments under different materials according to the characteristics of local decoration, functionality, parameterization, and so on. The impact of 3D printing technology on clothing design within the framework of intellectual property law is also being explored. The results show that the thermal comfort range of 3D printed garments is 24.1~26.6°C, and 3D printing materials with larger TCR can better regulate the comfort of garment design. This study explores parametric garment design using 3D printing, which is innovative.
