Design and Analysis of a 5-Degree of Freedom (DOF) Hybrid Three-Nozzle 3D Printer for Wood Fiber Gel Material

Abstract

Wood is an organic renewable natural resource. Cellulose, hemicellulose and lignin in wood are used in tissue engineering, biomedicine and other fields because of their good properties. This paper reported that the possibility of wood fiber gel material molding and the preparing of gel material were researched based on the wood fiber gel material as a 3D printing material. A five-degree of freedom hybrid three nozzle 3D printer was designed. The structural analysis, static analysis, modal analysis and transient dynamic analysis of 3D printers were researched, and the theoretical basis of the 3D printer was confirmed as correct and structurally sound. The results showed that the 5-DOF hybrid 3-nozzle 3D printer achieved the 3D printing of wood fiber gel material and that the printer is capable of multi-material printing and multi-degree-of-freedom printing.

“…Along with hemicelluloses and lignin, it can be used in tissue engineering and biomedicine because of their good properties. Wood fiber gel can be prepared as a 3D-printing material using a hybrid 3D printer with three nozzles and five degrees of freedom [5]. The printer is capable of multi-material and multi-degree-of-freedom printing, making the wood fiber gel suitable for multiple biomedical applications.…”
