3D printing to aid tissue replacement

Professor Arda Gozen looks to a future someday in which doctors can hit a button to print out a scaffold on their 3-D printers and create custom-made replacement skin, cartilage, or other tissue for their patients.

Gozen, George and Joan Berry associate professor in the Washington State University School of Mechanical and Materials Engineering, and a team of researchers have developed a unique scaffolding material for engineered tissues that can be fine-tuned for the tricky business of growing natural tissue.

The work is still in its early stages, and the researchers would like to figure out how to more precisely tune the process and final material. They might look at varying the composition of their three materials or printing at different temperatures, for instance.

Trying to imitate the vast complexity of natural tissue remains a challenge. Even a simple millimeter-sized piece of cartilage on the knee for instance, has three separate and distinct layers, each with different mechanical properties and functions.
