中文摘要：

依据生物学理论,以3D打印技术为研究对象,从物种概念及形成机理入手,具体围绕3D打印技术物种特性、物种形成的内外因及形成路径进行深入分析,清晰追溯3D打印技术的形成过程,理清3D打印技术物种形成的内部机理,为后续开展3D打印技术演化等研究奠定理论基础。

英文摘要：

Based on the theory of biology,this paper carries out the in-depth research on species characteristics,species formation reason and formation path of the 3D printing technology,starting from the concept of species and formation mechanism,clearly traces the forming process of 3D printing technology,and clarifies the internal mechanism of 3D printing technology,laying a theoretical foundation for the follow-up 3D printing technology evolution research.
