A 22-Year-Old Engineer 3D Prints Free Dentures for Low-Income Americans

Connor Gibson is 22 years old and he is printing free dentures for people who cannot afford them. He has no dental degree. He had almost no 3D printing experience three years ago. That did not stop him from building a mobile digital denture lab that now serves hundreds of patients through Remote Area Medical.

From Volunteer to Digital Technology Manager

Gibson first volunteered with RAM while attending Walters State Community College in Tennessee. The nonprofit provides free dental, vision and medical care through pop-up clinics across the United States. He saw that dentures were still made the old-fashioned way: molding, casting and weeks of waiting. Patients often had to return multiple times.

He decided to change the process. Gibson taught himself dental anatomy, digital design and the software needed to manufacture custom dentures. He studied videos, documents and anything else he could find. He said, "I made it my mission and studied up like I was doing a test."

The result is RAM's Mobile Digital Denture Lab. Two 3D printers run inside a mobile office on weekends. Gibson and his team can scan a patient, design the dentures and print them in a matter of hours. The old process could take three months. Gibson recently printed 35 sets of dentures in a single weekend.

The "Mirror Moments"

Gibson calls the first time patients see their new smiles "mirror moments." He has seen grown men weep. He has seen elderly widows stare in disbelief. The reaction never gets old, he says.

About 72 million American adults do not have dental insurance. Medicare does not cover dentures in most cases. For many patients, a new set of teeth is simply unattainable without help from organizations like RAM.

RAM has served more than 1 million patients and provided nearly $240 million in care since 1985. In 2026, the organization plans to host more than 90 full-scale medical, dental and vision clinics. Gibson hopes to add more mobile digital denture labs by the end of the year.

More Than a Printer

Gibson is not the first person to 3D print dentures. But he is credited with creating the first mobile denture lab in the United States. When he first pitched the idea at 3D printing conventions, vendors turned him away. He secured the first printers through grants. Today his work is recognized as a leading example of digital dentistry in action.

He said, "Never did I have the chance to step back and realize until that moment of 'whoa, this is the bigger picture of how I can utilize my engineering degree to be good for our nation and for our community.'"

The need is still far larger than the supply. Word spreads quickly about RAM clinics. People line up by the hundreds, sometimes thousands, seeking care. Gibson knows the lab cannot serve everyone yet. But each weekend brings more mirror moments, more smiles and more proof that 3D printing can change lives in very direct ways.
