Axtra3D, a US and Italy-based manufacturer of high-speed SLA systems, has launched the KeyModel Ultra Ivory resin for its Lumia X1 platform. Developed in collaboration with Keystone Industries, this material is also available in Sand and Light Gray colors. It is designed for thermoforming in clear aligners and dental restorations, offering precision and resistance to chipping during carving.

Technology that prevents fractures in dental models 🦷

The KeyModel Ultra Ivory resin is characterized by its high precision and non-chipping properties, allowing models to be carved and adjusted without the material fracturing. Its formulation ensures a smooth finish and sharp details, maintaining fast and consistent printing on the Lumia X1. This makes it suitable for applications requiring repetitive thermoforming, where model integrity is critical for the fit of aligners and restorations.

So the dentist won't curse while carving 😤

Because yes, we've all seen a dental technician hurl expletives when a model chips right at the final adjustment. With KeyModel Ultra Ivory, Axtra3D aims to avoid those moments of fury. Now you can carve like a plastic surgeon with a scalpel, not like a child with a toy chisel. That said, the material doesn't promise to prevent the patient from arriving late to their appointment.
