About 3D Bioprinting
What is 3D Bioprinting?

Based on computer-aided motion, extrusion-based 3D bioprinting precisely dispenses living cells and biomaterials layer by layer, generating structures that imitate native human tissues and biological systems. The technology brings key values of automation, biomimetic architecture, and on-demand biomanufacturing. It is widely applicable to the fields of bioengineering and medicine, from in vitro applications in novel product screening, disease modeling, and animal alternative experimentation to in vivo applications in tissue transplantation and regeneration.
