Resina KeyOrtho IBT

There are certain steps that need to be taken before use. The resin should be tempered to ambient temperature (20-25°C) prior to printing. The bottle should be shaken 1 hour prior to use in order to achieve consistency of the resin and to prevent bubbles. If bubbles are still present, they should be removed with a clean spatula. The KeyPrint resin should only be used in accordance with the product-specific predetermined settings for the user’s DLP 3D printer with a 385nm - 405 nm UV light source. Any other equipment requires validation by the manufacturer.

The post processing of parts 3D printed with the KeyOrtho IBT dental resin consists in washing and curing. A tray 3D printed with KeyOrtho IBT and post-processed just like shown in the video provided by the manufacturer is a biocompatible medical device effective for its intended use.

As demonstrated in the video, the part should be cleaned with IPA alcohol (at least 97%) twice (fresh IPA alcohol each time) and then dried with compressed air. Residual resin will be visibly glossy and should be removed by repeating the washing and drying steps. Once the parts are clean, they must be cured. They should be placed in the validated curing machine (flat to prevent warping). The validated cure box settings can be consulted on the manufacturer’s website.

Precautions should be taken at all times to ensure user safety. It is recommended to use protective gloves and garments, and a face screen to prevent burns caused by hot resin.
