A Design Method Based on 3D Printing for the Integration of Human Computer Dynamic Interaction and Digital Sculpture

The continuous popularization and application of computer 3D modeling and 3D printing technology in the field of art design has improved and changed the traditional design and production mode to a certain extent. In order to solve the shortcomings of the existing research on human-machine dynamic interaction of 3D printing and digital sculpture, this paper discusses A3D digitalization, the mainstream technology of 3D printing, human-machine dynamic interaction and traditional sculpture making, and briefly discusses the image preprocessing and human-machine interaction and digital design software of 3D printing based on human-machine interaction. In addition, it designs the technology of human-computer interaction information extraction, visual interaction key frame selection, equipment operation and 3D printing body structure digital molding technology. Finally through the concrete experiment analysis. The results show that the average inter-frame distance error of the key frame sequence extracted based on the visual interaction method is the smallest. The calculated frame spacing error is as low as 0.029. The minimum error of manual extraction was 0.557. The minimum X-means clustering error is 0.047. Therefore, it is verified that the integration method of human-machine dynamic interaction and digital sculpture based on 3D printing designed in this paper has high practical value.
