About 4D Bioprinting
What is 4D Bioprinting?

Based on computer-aided motion, extrusion-based 4D bioprinting precisely dispenses living cells and biomaterials layer by layer, generating structures that imitate native human tissues and biological systems. Because these are often further incubated to proliferate, mature and change over time, this dimension of time makes it 4D. 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.
