Research on Printing Large-Scale Models Using Multi-Color 3d Printing Technology

Abstract

Multi-color 3D printing, as a branch of 3D printing, is continuously driving the advancement of 3D printing. Multi-color 3D printing technology has now entered a new phase of rapid development, overcoming the limitations of traditional printing methods in producing large-scale multi-color models. This paper reviews research progress in printing large-scale models using multi-color 3D printing technology, against the backdrop of advancements in multi-color 3D printing. This paper first introduces the principles and significance of multi-color printing, then describes research progress from three aspects: material selection, partitioning strategies, and printing equipment. Finally, it analyzes and discusses the challenges that remain to be addressed and potential directions for future development in this field. This paper analyzes the interlayer bonding strength and thermal warpage mechanical properties of materials from two research perspectives. It then clarifies the significant role of surface subdivision algorithms in multi-color printing and large-scale model segmentation. Finally, by comparing single-nozzle and multi-nozzle systems, it concludes on the capabilities and limitations of multi-nozzle extruders. It is suggested that explore the mechanical properties in future research—such as interlayer adhesion—of different colors and materials, or incorporate reinforcing materials to modify the base materials. This paper proposes improvements and developments for multi-nozzle extruders to find equipment more suitable for large-scale multi-color printing.
