Axtra3D, a US- and Italy-based manufacturer of high speed SLA 3D printing systems, has launched KeyModel Ultra Ivory for its Lumia X1 platform through a dental materials partnership with Keystone Industries, a dental materials manufacturer. Ivory is the only validated color of the resin on the Lumia X1 at the time of the press release, although KeyModel Ultra is also available in Sand and Light Gray.
KeyModel Ultra is described as a high-precision, ultra fast, non-chipping resin with a proprietary thermoforming quick-release agent. Axtra3D states that the material can be carved after curing without chipping, a common issue in dental model production. The resin is intended for thermoforming workflows used in clear aligners and restorations, and is designed to deliver smooth surface finish, sharp detail, and fast, consistent printing.
Arianna Waters, Dental Research Manager at Keystone Industries, described the validation process as a staged workflow between the companies. “Keystone Industries’ 3D Dental R&D team worked closely with Axtra3D to validate KeyModel Ultra on the Lumia X1 printer,” Waters said. “Axtra3D’s optimized resin settings produced high-quality parts that met stringent dimensional accuracy requirements, allowing the team to advance efficiently to mechanical testing. With several additional validations currently underway and set to be announced in the coming months, this partnership is off to a strong start.”
Additional material validations are now underway for KeyOrtho Model, KeyGuide, KeySplint Hard Clear, KeySplint Soft, and KeySplint Soft Clear. Rajeev Kulkarni, Chief Strategy Officer at Axtra3D, pointed to the production bottlenecks the companies are targeting. “This material is designed to improve dental lab productivity, reduce cost per part, and minimize rework that drives waste and delays. By removing a key downstream failure point in carving and finishing, it helps increase throughput and operational efficiency. It also streamlines thermoforming workflows, improving turnaround times for high-volume applications like clear aligners and restorations. The result is more predictable output at scale, with higher consistency and reduced operational variability.”
Lumia X1 is Axtra3D’s flagship Hi-Speed SLA system. Axtra3D describes the machine as combining its Hybrid PhotoSynthesis resin polymerization process with TruLayer, its layer separation technology. Hybrid PhotoSynthesis uses both a laser and a DLP system simultaneously, while TruLayer enables rapid detachment of the active print layer. Axtra3D states that the configuration delivers a 20X throughput improvement while preserving the accuracy and surface fidelity associated with SLA parts. KeyModel Ultra is now available for purchase through Axtra3D sales channels.
Axtra3D expands validated workflow around Lumia X1
Axtra3D has recently been adding validated materials and process controls around its Lumia X1 platform, pointing to a broader effort to reduce variability in production. At AMUG 2026, the company introduced three elastomer resins for North America, Loctite 3D IND475, Loctite 3D Med414, and Ultracur3D EL 4000, and opened US pre-orders for Axtra.Workflow. That system connects build preparation, printing, post-processing, inspection, and data tracking through Axtra.Wash, Axtra.Cure, and Axtra.Insight, extending the platform beyond print hardware alone.
That earlier workflow push is meaningful because dental production depends on repeatable processing as much as on print resolution. Axtra.Workflow combines Hybrid PhotoSynthesis printing with automated washing, drying, UV and thermal curing, and process monitoring intended to support traceable output. Axtra.Insight collects data from more than 155 sensors across the workflow, while Axtra.Cure combines ultraviolet and thermal curing in a single unit with three independently controlled UV wavelength bands and thermal cycles up to 250 °C. In that context, the KeyModel Ultra validation is not just another materials addition. It fits into a wider attempt to qualify specific resins within a more controlled manufacturing process.
