Bioprinting is an emerging technique to create three-dimensional (3D) cell-incorporated constructs from biomaterials and living cells in a layer-by-layer manner. Distinctive from other methods (e.g., porogen-leaching, freeze drying), bioprinting techniques allow the fabrication of constructs in a controllable manner, with architecture and mechanical/biological properties mimicking those of human native tissue or organs. As such, bioprinted constructs have found wide applications related to biomedical engineering, including tissue engineering (TE) and combating infectious diseases (CID). Our long-term goal is to advance the theoretical and practical basis of bioprinting tissue-like constructs for biomedical engineering applications.
