United Therapeutics Corporation (Nasdaq: UTHR), a public benefit corporation working in partnership with 3D Systems Corporation (NYSE: DDD) has produced the world’s most complex 3D printed object – a human lung scaffold – and demonstrated it at the LIFE ITSELF Conference in San Diego. The event was organized and hosted by Dr. Sanjay Gupta and Marc Hodosh and was sponsored by CNN, United Therapeutics, and other prominent corporate leaders in healthcare.
Dr. Martine Rothblatt, United Therapeutics’ Chairperson and Chief Executive Officer and Chuck Hull, 3D Systems’ Co-Founder, Executive Vice President, and Chief Technology Officer for Regenerative Medicine, explained to conference attendees during a presentation entitled What’s the Future of Organ Transplantation? that these 3D printed human lung scaffolds designs consisted of a record 44 trillion voxels that layout 4,000 kilometers of pulmonary capillaries and 200 million alveoli.
Scientists at United Therapeutics plan to cellularize these 3D printed human lung scaffolds with a patient’s own stem cells to create tolerable, transplantable human lungs that should not require immunosuppression to prevent rejection. This latest achievement represents the latest milestone of an ongoing research project that was first made public in 2018.
“Last week, it was exciting to show the public our 3D printed human lung scaffold, but we’re thrilled to share that our 3D printed lung scaffolds are now demonstrating gas exchange in animal models. We are regularly printing lung scaffolds as accurately as driving across the United States and not deviating from a course by more than the width of a human hair,” said Dr. Rothblatt. “With the continued hard work of dedicated scientists and engineers at United Therapeutics and 3D Systems, we hope to have these personalized, manufactured lungs cleared for human trials in under five years.”
