HeyGears builds high-precision 3D printing systems for dental manufacturers using photopolymerization technology.
$420KSeries C
A $400K Series C in 2026 signals dental 3D printing is still grinding through unit economics rather than scaling—this isn't a breakout round, it's survival capital in a market where margins are thin and adoption is slower than the hype suggested. If you're building in precision manufacturing or materials science, watch whether HeyGears can actually move the needle on cost-per-part; if they can't, it means the photopolymerization stack isn't the moat people thought it was.
