KeyTray resin

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 385-405 nm UV light source. Any other equipment requires validation by the manufacturer.

The post processing of parts 3D printed with the KeyTray dental resin entails 3 easy steps.

1. The part should be cleaned with IPA alcohol (at least 97%) just like shown in video 1 and then dried with compressed air. Residual resin (visibly glossy) should be removed by repeating the washing and drying. The manufacturer highly discourages the use of denatured alcohol or ethanol for cleaning as it may diminish or degrade the quality of the finished parts.
2. The part should be placed in a curing machine (flat to prevent warping). The validated cure box settings can be consulted on the manufacturer’s website. Before the part is removed from the curing machine, it should be allowed to cool completely to prevent surface defects or warping.
3. Final processing such as polishing can be done now with the help of the KeyPolish kit. KeyPrint shows how to polish parts 3D printed with their resins in this video.

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.
