The printing of three-dimensional tissue has taken a major step forward with the creation of a novel hybrid printer that simplifies the process of creating implantable cartilage.
The printer has been presented Nov. 22, in IOP Publishing's journal Biofabrication, and was used to create cartilage constructs that could eventually be implanted into injured patients to help re-grow cartilage in specific areas, such as the joints.
The printer is a combination of two low-cost fabrication techniques: a traditional ink jet printer and an electrospinning machine. Combining these systems allowed the scientists to build a structure made from natural and synthetic materials. Synthetic materials ensure the strength of the construct and natural gel materials provide an environment that promotes cell growth.
