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

A 22-year-old engineer turned a nonprofit clinic into a mobile denture factory

Connor Gibson, a 22-year-old engineer based in rural Tennessee, has built the first mobile digital denture lab in the United States. Working with Remote Area Medical, he now prints custom dentures in hours for patients who would otherwise wait months or go without. Gibson had no background in dentistry or additive manufacturing when he started.

Remote Area Medical, headquartered in Rockford, Tennessee, operates free mobile clinics for dental, vision, and medical care across the United States. Before Gibson arrived, the organization made dentures the traditional way: molding, casting, and multiple patient visits. The process could take three months per set. Gibson taught himself CAD software and denture design, then outfitted a mobile office with two 3D printers that run continuously during clinic weekends.

The workflow begins with an intraoral scan of the patient's mouth. Gibson uses that data to design a custom set of dentures on his computer, adjusting fit, bite, and aesthetics for each individual. The design is then sent to a resin 3D printer, which builds the denture layer by layer. The entire process, from scan to finished set, can be completed in a single day. Gibson has printed as many as 35 sets in one weekend.

Why this gap existed in the first place

The United States has roughly 35 million people who live in dental health professional shortage areas, according to federal data. For low-income patients without dental insurance, even basic dentures can cost thousands of dollars. RAM's clinics serve as a stopgap, but the old manufacturing method limited throughput. Each set required a dental lab and several appointments. Gibson's mobile setup eliminates those constraints by bringing the lab directly to the patient.

The economic case is stark. A conventional denture set from a commercial lab costs between $1,500 and $3,000. Gibson's per-set material cost is a fraction of that. The trade-off is labor: Gibson and a small team of volunteers manage scanning, design, printing, and fitting on compressed timelines. The model works because RAM's clinics are staffed by volunteer dentists and hygienists who handle patient care while Gibson runs the fabrication side.

Scaling the operation

RAM plans to host more than 90 full-scale clinics in 2026, up from about a dozen events per year in 2013. The organization has taken notice of Gibson's impact. CEO Chris Hall, who joined RAM in 2013, sees the digital denture lab as an extension of founder Stan Brock's original mission: deliver care to people who cannot reach it. "He embodies everything about Brock and the legacy of this organization," Hall told CNN.

Gibson, a native of rural Seymour, Tennessee, first encountered RAM after seeing the 2020 documentary "Medicine Man: The Stan Brock Story" at a theater with his father in 2023. He had never heard of the nonprofit despite its headquarters being in his own corner of the state. He began volunteering while studying engineering at Walters State Community College, then turned the denture lab into his full-time mission. "I made it my mission and studied up like I was doing a test," he said.

The next phase involves building more mobile labs. Gibson hopes to have additional units operational by the end of 2026. Each lab would duplicate the workflow he has already proven, allowing RAM to run simultaneous clinics in different states on the same weekend. The bottleneck is not printing capacity, which is easily expanded by adding more machines. It is training volunteers to scan, design, and fit dentures under clinic conditions. Gibson is writing standard operating procedures to speed that process.

For patients, the difference is immediate. A person who has been without teeth for years walks in on Saturday morning and leaves with a functioning set by evening. Gibson sees the work as more than engineering. "We're all one slip or one fall away," he said. That framing keeps the focus on the patient, which is rare in stories about 3D printing technology.
