Axtra3D Adds Keystone's KeySplint Hard Clear to Its Lumia X1

Axtra3D has certified Keystone Industries' KeySplint Hard Clear resin for use on its Lumia X1 Hi-Speed SLA printer, making it the second Keyprint material to gain approval on that platform.

KeySplint Hard Clear is a rigid, transparent resin designed for splints, retainers, and surgical guides. It joins KeyModel Ultra, which was validated earlier in 2026, and significantly broadens what dental labs can produce on the Lumia X1 without leaving the Axtra.Solutions material ecosystem.

The Lumia X1 uses Axtra3D's patented Continuous Digital Light Processing approach, which combines the speed of traditional SLA curing with layerless printing for smoother surfaces. Approved materials are a key selling point here, because labs cannot afford to run uncertified resins on production patient files.

Keystone Industries has been building its dental materials portfolio for years, and this validation places its clear splint material directly on a high-speed platform that competes with EnvisionTEC and Formlabs in the dental space.

The deal is also a sign of how material partnerships are shaping the resin market. Printer makers no longer win on hardware alone. The real lock-in happens when the validated material library is deep enough that switching platforms becomes a regulatory headache for labs that already passed qualification tests.
