A Revolutionary New System for 3D Bioprinting Human Tissue With Increased Structural Integrity

3D Bioprinted Ear

The Wake Forest Institute for Regenerative Medicine created the Integrated Tissue and Organ Printing System (ITOP) for 3D bioprinting human tissue with increased structural integrity using biodegradable plastic scaffolding. The tissue is printed around layers of biodegradable polycaprolactone, which gives the printed form a rigid structure to build around before it slowly dissolves away.

The polycaprolactone structure allows the ITOP system to create more complex structures than earlier work in 3D bioprinting, including bone, cartilage, and skeletal muscle. The Wake Forest Institute for Regenerative Medicine is working on further developing the ITOP to be able to print even more complex tissue and organs.
