中文摘要：

三维（3D）打印是当今科研界乃至商业界的一大热点,被认为是第三次工业革命或制造业的新突破点。人体器官打印已被当做概念股炒作上市,吸引了无数人的注意。但器官3D打印还处于刚刚起步阶段,需要做的工作很多。尤其是复杂器官打印面临着巨大的困难和挑战。其中最主要的一个挑战就是分支血管和神经系统的快速构建。近年来已经有大批优秀的科研工作者投入其中,内容涉及人体中各个器官,如骨骼、肾脏、肝脏、心脏、大脑,并取得了一定的成绩。这里分别介绍3D打印技术在大段骨修复材料、血管与血管网、人工肝脏、血管化脂肪组织几方面的最新的研究成果以供大家参考。

英文摘要：

Three dimensional （3D） printing is a hot topic in today’s scientific research and commercial areas. It is recognized as the third industry revolution or new breakthrough of manufacture. Human organ printing has been put forward into equity market as a concept stock and attracted a lot of attention. However, organ printing is still in its infancy and a lot of work needs to be done. Especially, complex organ printing encounters enormous difficulties and challenges. Main two of them are rapidly construction of branched vascular and nerve systems. Recently, a large number of outstanding scientists flung them into this area, and have made some headways in nearly every human organs, such as the bone, kidney, liver, heart, and brain. Some novel achievements in the large bone repair material, blood vessel and vascular network, artificial liver and vascular adipose tissue printing fields are introduced for reference.
