In dental technology, 3D printing has become established, but for dentures and provisionals it often hits a practical limit: multiple materials can usually only be produced sequentially. That means stopping the print, changing material, flushing resin paths, repositioning parts, and then recalibrating again. Every interruption lengthens the process and increases the risk of handling and fit errors—especially with colored or functionally graded components.
Longtime lab owner Mart Goldberg wants to circumvent this problem with a patented methodology that brings multiple polymers together in one automated print cycle. Technically, the approach relies on “functional region mapping,” i.e., assigning defined functional zones within the part, combined with an automated deposition sequence and controlled transitions between different materials. The idea is to stop treating material changes as a process break and instead make them a planned part of exposure control and material management within the print job.
“I spent decades watching skilled technicians perform the same manual interventions over and over – changing materials, cleaning equipment, repositioning parts,” said Goldberg. “The automation we’ve achieved can reduce manual labor in a printing cycle by approximately 90%. But it’s not just about efficiency. The stable chemical bonding between dissimilar polymers and natural-appearing material transitions – that’s what will change patient outcomes.”
The methodology is designed for the FUGO Precision 3D system, which uses a centrifugally driven vat photopolymerization process. The provider cites repeatability below 30 micrometers and throughput of up to ten times compared with traditional workflows, including integrated washing, drying, and curing in a single machine.
Alexander Meseonznik, CEO of FUGO Precision 3D, praised the collaboration: “Mart brought something we couldn’t develop internally – decades of hands-on experience understanding exactly what dental laboratories need. His methodology transforms our hardware into a complete solution for multi-material manufacturing. The combination creates capabilities that simply don’t exist anywhere else in the market.”
“There are 120 million Americans suffering from tooth loss,” Goldberg noted. “This isn’t a prototype or a concept – we’re showing production-ready technology that dental laboratories can implement today. The methodology works, and we’re ready to help manufacturers transform their operations.”
A live demonstration has been announced for LMT Lab Day 2026, February 19–21 in Chicago. Goldberg points to “120 million” people affected by tooth loss in the U.S. and sees the technology as immediately deployable. For labs, the decisive factors will likely be how stable material batches, long-term bonding, and validation under series-production conditions turn out.
