Negative Poisson's Ratio Material Structure Based on 3D Printing and Its Application in Medical Field

首先对3D打印的整体框架进行简要的介绍,其中包括了增材制造制程的基本原理,七大制程的分类及小结。其次对常见的负泊松比结构进行简介,与一般传统结构相比,负泊松比结构的能量吸收能力更强,抗断裂性能更好,耐压痕性能更好,这些都是其在打印制造方面所具有的优势。最后对3D打印,负泊松比结构的应用以及两者的结合应用,从医疗领域的不同角度进行介绍,包括心血管支架的应用、生物医用材料结构制备应用研究、腰椎间盘植入物应用等。该文对3D打印负泊松比的结构设计思路,对医疗领域的新应用方向有指导作用。负泊松比材料的应用领域非常广泛,不仅可用于医疗领域,也可用于机械设备、汽车制造与航空航天等高科技领域。

First of all,the overall framework of 3D printing is briefly introduced,including the basic principles of the additive manufacturing process,the classification and summary of the seven processes.Secondly,the common negative Poisson’s ratio structure is introduced.Compared with the conventional structure,the negative Poisson’s ratio structure has stronger energy absorption capacity,better fracture resistance and better indentation resistance,which are its advantages in printing manufacturing.Finally,3D printing,the application of negative Poisson’s ratio structure and the combination of the two are introduced from the different perspective of medical field,for example,the application of cardiovascular stent,biomedical material structure preparation,and lumbar disc implants.This paper suggests that the structural design of negative Poisson’s ratio in 3D printing guides the development of new application directions in the medical field.Negative Poisson’s ratio materials have a wide range of applications,not only in the medical field but also in mechanical equipment,automotive manufacturing,aerospace,and other high-tech industries.
