Semantic Guided Multi-directional Mixed-Color 3D Printing

Abstract

Fused deposition model (FDM) 3D printing technology, which directly manufactures physical objects from digital 3D models, has become a research hotspot in the manufacturing field in recent years. The current 3D printing has problems such as single printing direction and monotonous printing color. These problems usually waste more human and material resources. To address this problem, this paper studies multi-directional mixed-color FDM 3D printing technology. By introducing a five-axis mechanical system, the model is divided into multiple components that can be printed in different direction to realize multi-directional printing; furthermore, a extrusion head with color mixing function is designed to realize colorful printing, combined with the color mixing algorithm, it can mix the three colors of filament according to a certain proportion to achieve the desired color; and then combined with semantic-guided model segmentation to realize printing with user assigned colors. Finally, a control scheme is designed for clean color boundary.
