Biotechnology firm United Therapeutics has showcased what it claims to be the “world’s most complex 3D printed object” in partnership with 3D printer manufacturer 3D Systems at the recent LIFE ITSELF conference in San Diego.
The partners have produced a 3D printed human lung scaffold capable of demonstrating gas exchange in animal models, and are now planning to cellularize the scaffold with a patient’s own stem cells to create tolerable, transplantable human lungs.
