Description
pro3dure´s GR-14.1 denture is a certified Class IIa biocompatible 3D printing resin for the production of denture bases. By its low water absorption (< 25μg/ mm²) and a water solubility (< 4μg/ mm²) according to ISO 20795-1:2013 the GR-14.1 denture meets the requirements on dental materials. Furthermore, the low shrinkage of GR-14 denture resin (< 1%) compared to traditional PMMA materials guarantees a high level of accuracy and a perfect fit of the denture base.
COMPATIBLE WITH DLP/LCD/SLA 3D PRINTERS

Important
-
To avoid detrimental effects on material quality do not expose the liquid material to irradiation under any circumstances.
-
Deviations from the described manufacturing process may lead to different mechanical and optical properties of the GR-11 material.
-
Ensure personal protective gear during processing.
-
Caution: Polymerised resins are chemically resistant -avoid stains on clothing.
-
Avoid any contact with skin and eyes. In case of accidental contact, rinse with adequate running water, consulting a doctor if necessary.
