Using 3D Printing, MakerBot and Feinstein Institute for Medical Research Create Cartilage to Repair Tracheal Damage

Results are showcased at 51st Annual Meeting of The Society of Thoracic Surgeons
San Diego, CA – Investigators at The Feinstein Institute for Medical Research have made a medical breakthrough using 3D printing on a MakerBot® Replicator® 2X Experimental 3D Printer to create cartilage designed for tracheal repair or replacement. The results were reported today at the 51st Annual Meeting of The Society of Thoracic Surgeons in San Diego, in a presentation by Todd Goldstein, an investigator at the Feinstein Institute, part of the North Shore-LIJ Health System. This is a first for medical research where regular MakerBot PLA Filament was used to 3D print a custom tracheal scaffolding, which was combined with living cells to create a tracheal segment.

Mr. Goldstein, a PhD candidate at the Hofstra North Shore-LIJ School of Medicine, has been working with a team of surgeons at the North Shore-LIJ Health System for the past year on determining if 3D printing and tissue engineering could be used for tracheal repair and replacement. Tracheal damage can be caused by tumor, endotracheal intubation, blunt trauma, and other injuries. Narrowing and weakness of the trachea can occur and are often difficult to repair. There have been two traditional means of reconstructing a damaged trachea, but both techniques have limitations. Lee Smith, MD, chief of pediatric otolaryngology at Cohen Children’s Medical Center and David Zeltsman, MD, chief of thoracic surgery at Long Island Jewish Medical Center, both part of the North Shore-LIJ Health System, came to Mr. Goldstein and Daniel A. Grande, PhD, director of the Orthopedic Research Laboratory at the Feinstein Institute, and asked if 3D printing might offer a solution. Drs. Smith and Zeltsman originally surmised that incorporating 3D printing and tissue engineering to grow new cartilage for airway construction might be possible in ten to 20 years. Mr. Goldstein and Dr. Grande did it in a month.
