Axtra3D Lumia X1 Adds KeySplint Hard Clear for Dental Splints and Retainers

Axtra3D has added a second validated dental material to its Lumia X1 Hi-Speed SLA system. KeySplint Hard Clear, a biocompatible resin from Keystone Industries, is now certified for the Lumia X1, joining KeyModel Ultra in the Axtra.Solutions portfolio.

The resin is formulated for post-trauma tooth immobilization and orthodontic retainers. It is designed to withstand daily wear, including chewing forces, bruxism, and constant contact with saliva and beverages. According to Keystone, the material resists staining and abrasion, and its Clear variant is the only color currently validated specifically for the Lumia X1. The same resin is also available in Light Violet, but that version has not yet passed Axtra3D's validation process.

Axtra3D positions the Lumia X1 as an open platform rather than a proprietary consumable lock-in. The company says it is working to validate four additional KeyPrint materials: KeyGuide, KeyOrtho Model, KeySplint Soft, and KeySplint Soft Clear. If all four pass, the Lumia X1 will have six validated dental materials from a single partner, covering models, surgical guides, soft and hard splints, and retainers.

The Lumia X1 uses Axtra3D's Hybrid PhotoSynthesis process, which combines a laser and a 4K DLP projector in a single imaging pass. The company says this cures bulk volumes and fine surface details simultaneously, cutting throughput time compared to traditional layer-by-layer SLA. For dental labs, the practical effect is that a nightguard or retainer can be printed, post-cured, and finished in a single work session without sacrificing fit accuracy.

KeySplint Hard Clear is available now through Axtra3D sales channels. The resin ships with a material safety data sheet and ISO 10993-5 and ISO 10993-10 biocompatibility documentation, which labs need for patient-facing devices.
