Recent Advances in Bioink Design for 3D Bioprinting
Despite recent advances in tissue engineering, there remains a lack of tissues and organs for transplantation and a shortage of tissue models for drug discovery and testing. Some of the hindrances involve conventional techniques, such as porogen-leaching, injection molding, and electrospinning due to the limited control over scaffold architecture, pore shape, composition, size, and distribution.
3D bioprinting overcomes these barriers by enabling fabrication of scaffolds, devices, and tissue models with a high complexity. Using computer-aided design, 3D printing facilitates construction of tissues from commonly used medical imaging like x-rays, MRI's, and CT scans.Read More
