GVA-26

GVA-26 Gingiva Resin was developed for dental applications where models must replicate soft tissue behavior without permanent deformation. Its Shore A 37 hardness provides gum-like compressibility, while the low compression set (1% after 72 hours) ensures reliable shape recovery. Parts maintain both flexibility and tear resistance (7.8 kN/m) over repeated handling, making this flexible resin ideal for removable implant and teeth gingival masks, emergence profile shaping, aesthetic evaluations, and training models.

GVA-26 is designed to work even on low-powered MSLA/LCD 3D printers equipped with LED light sources emitting 365-420nm UV light. Compatible with color and monochrome LCD 3D printers like Phrozen Sonic Mini 8K, Elegoo Saturn, or Anycubic M5.
It also works great on DLP 3D printers like Asiga, Elegoo Mars 4, or Anycubic Photon D2.

You can find recommended 3D printing settings for many 3D printers here: AmeraLabs resin settings.

After post-cure, the print does not feel sticky or tacky and is pleasant to touch. The surface of the GVA-26 Gingiva Resin print is smooth with Shore A 37 hardness – soft and compressible like gum tissue.
Since this flexible resin is designed for dental applications, printed parts can be trimmed, cut, or drilled with scalpels or slow-speed handpieces.
Resin is carefully pigmented and available in gum-pink color.

For a successful print, we recommend:

• Heat the resin to ~25 °C before printing and shake gently to ensure consistent viscosity.
• Level your build plate.
• If it’s your first print with this resin, print something small first. We recommend the AmeraLabs Town calibration model.
• Find initial printing settings here: AmeraLabs resin settings.
• Use moderate lift speeds (75 mm/min) and minimize suction zones in model design – hollow designs help reduce suction forces.
• Use long wait times of 2–10 s before curing, especially for large or hollowed models and big printers.

GVA-26 Gingiva Resin has moderate viscosity and is designed for clean, reliable washing with standard IPA. Supports can be removed before or after washing. Important: Do not leave GVA-26 submerged in IPA for more than 15 minutes at a time. Overwashing can soften the material and reduce final flexibility.
If you use a Wash and Cure station, submerge the printed mask in IPA for 10–15 minutes maximum, then remove and air-dry thoroughly. For complex geometries, repeat short washes as needed to clear uncured resin from undercuts or contact areas.
Soaking in IPA without agitation is acceptable for short durations, but gentle agitation improves results.
If using an ultrasonic cleaner, place the part in a sealed container with IPA, then into a water-filled ultrasonic unit for 5 minutes only. Avoid heating.
After washing, dry completely using compressed air or ambient drying for at least 30 minutes before UV curing. Any residual IPA will affect softness and surface finish.

It is easier to remove supports before post-curing. However, you can also post-cure a print with supports and remove them later. Depending on the model, this can help maintain precise gingival contours during curing. Post-curing time is 15–20 minutes under 365–405 nm UV light (until the surface is smooth and non-tacky). Do not exceed 20 minutes – overcuring reduces flexibility and shape memory. For optimal results, post-cure immediately after thorough drying. After proper post-curing, the surface of GVA-26 printed gingival masks should be completely non-tacky, smooth, and retain full gum-like softness and compressibility.

GVA-26 is suitable for dental applications where printed masks need to be trimmed or adjusted post-printing. The material will not significantly tear or deform during cutting, trimming, or drilling with standard tools. The material has been tested for compatibility with scalpels, carbide/diamond burs, and slow-speed handpieces (below 10,000 RPM). Avoid high feed rates that can cause tearing; test with your specific tools if advanced machining is expected.
