摘要

Over the past 30 years,additive manufacturing(AM)has developed rapidly and has demonstrated great potential in biomedical applications.AM is a materials-oriented manufacturing technology,since the solidification mechanism,architecture resolution,post-treatment process,and functional application are based on the materials to be printed.However,3D printable materials are still quite limited for the fabrication of bioimplants.In this work,2D/3D AM materials for bioimplants are reviewed.Furthermore,inspired by Tai Chi,a simple yet novel soft/rigid hybrid 4D AM concept is advanced to develop complex and dynamic biological structures in the human body based on 4D printing hybrid cera-mic precursor/ceramic materials that were previously developed by our group.With the development of multi-material printing technology,the development of bioimplants and soft/rigid hybrid biological structures with 2D/3D/4D AM materials can be anticipated.
