Abstract:

BACKGROUND: 3D bioprinting technology can be used to print non-cell and cell-laden materials, which provides a new pathway to solve the lack of transplanted organs or bio-patches.

OBJECTIVE: To conclude the printing mechanisms, kinds, biological and mechanical characteristics of hydrogels based on the development and advance in 3D extrusive bioprinting hydrogel.
METHODS: A computer-based search of PubMed database was performed to retrieve relevant articles published between 2006 and 2016, with the keywords of “3D bioprinting/three-dimensional bioprinting; extrusion/extrusive; cell-laden/cells/cellular; hydrogel”.

RESULTS AND CONCLUSION: 3D bioprinting is characterized as simple principle, controlled process, and less energy production, which can manufacture personalized organs or scaffolds by rapid prototyping technology, and precisely construct tissues with controllably distributed cells to mimics the physiological circumstance. However,

the following aspects are still at an initial stage, including the biological behaviors of cells in hydrogel, the interactions between cells and hydrogels and the elevation of micro-nano precision of printing. With solutions to these problems, 3D bioprinting may become another novel construction method in the tissue engineering.
