AmeraLabs launches flexible gingiva resin for precisely post-processable dental models

AmeraLabs announces GVA-26 Gingiva Resin, a light-curable material for MSLA and DLP printing systems tailored to the needs of dental laboratories. The focus is on enabling post-processing of printed soft-tissue sections directly on the working model without masks tearing or permanently deforming. The resin features a Shore A hardness of 37, combining rubber-like compliance with sufficient structural strength for repeated handling.

According to the manufacturer, GVA-26 achieves a tear propagation resistance of 7.8 kN/m and a permanent compression set of 1 percent after 72 hours at 25 °C. These values target tasks such as exposing emergence profiles, adjusting contact points, or drilling for abutments.

“Dental technicians need gingival masks they can actually work with after printing,” said Andrius Darulis, co-founder of AmeraLabs. “GVA-26 gives labs the flexibility to make precise adjustments directly on the model – cutting emergence profiles, trimming contact points, drilling for abutments – without the mask tearing or staying compressed. It behaves like real soft tissue should.”

In practice, the material is designed to work with common lab tools, including scalpels, carbide and diamond burs, and low-speed handpieces up to below 10,000 rpm. The post-processing workflow remains conventional: an IPA wash for around 10–15 minutes followed by UV post-curing. AmeraLabs specifies dimensional change of under 0.5 percent after curing, and describes a smooth, non-tacky surface along with a low-odor formulation suitable for lab environments. Compatibility covers most resin vats with FEP, NFEP, PFA, ACF, or HDF film.

Applications include removable implant and gingiva masks, realistic test setups for aesthetic and functional evaluation, and training and demonstration models. GVA-26 will be available from November 10, 2025 in container sizes of 500 milliliters, 1 liter, and 5 liters via the online shop and authorized distributors. For labs that need to precisely adapt soft tissue on models, the resin addresses a gap between elastic feel and reproducible machinability.
