Three-dimensional (3D) bioprinting technologies play significant roles in various facets of the medical field, such as bioengineering, tissue repair, scaffolds, biomedical devices, and drug. As a versatile manufacturing technology, 3D bioprinting is able to overcome the constraints of other conventional methods and shows potential for future advancements in the field of biology. Nevertheless, the existing 3D bioprinting technologies still grapple with significant challenges in materials, equipment, and applications. Therefore, it is essential to select appropriate bioprinting method in alignment with the required application. In this review, we aim to cover the development, classification, and application of 3D bioprinting, with a particular emphasis on the fundamental printing principles. Additionally, we discuss the potential of 3D bioprinting in terms of materialization, structuralization, and functionalization, highlighting its prospective applications. We firmly believe that 3D printing technology will witness widespread adoption in the future, as it has the potential to address the limitations associated with multi-size, multi-material, multi-cell, and high-precision bioprinting.
