Instructions For Use
The SprintRay IDB 2 resin is a light-curable polymerizable resin intended to be used with extraoral curing light equipment. The IDB 2 resin is indicated for the fabrication, by additive manufacturing, of Indirect Bonding Tray (IBT). SprintRay IDB 2 resin is offered in clear color. The material is an alternative to traditional IBT material. SprintRay IDB 2 Resin is intended exclusively for professional dental work. Fabrication of IBT with SprintRay IDB 2 Resin requires a 3D design of the custom device designed by a qualified provider. It also requires a 3D Printer and Cure System to produce the devices.
The IDB 2 resin is contraindicated in case of the following:
If a patient is known to be allergic to any of the ingredients.
Direct intraoral contact of uncured or partially uncured material.
For every application that is not part of the indication (see above).
Handling and Processing
IDB 2 resin is non-toxic in both liquid and solid form, and it is classified as Biocompatible material. It is also classified as a sensitizer, which means that exposure over time can cause your body to have a mild allergic reaction. May cause skin irritation. May cause an allergic skin reaction. May cause severe eye irritation. May cause respiratory irritation. Here is how to handle resin safely:
Always wear gloves
Always wear gloves when handling uncured resin. Whether you are pouring, removing
printed parts from the platform, or even after they have been washed, must wear gloves
to limit exposure to resin.
3D printing resins contain chemicals of different weights; therefore, it is essential to mix
resin before every print thoroughly. For resin already in the tank, use provided resin wiper
to stir the material gently. If pouring from a bottle, shake the bottle vigorously for several
minutes before dispensing
Check expiration dates
Resin has a shelf life; it is essential to keep an eye on the expiration date. The use of
expired resin will likely result in failed prints, as the compounds required for curing break
down and will not activate properly. The expiration date for resins is printed on the back
of the bottle.
Dispose of properly
Liquid resin should be cured before being disposed of. Pour liquid resin into a clear
container and set it in direct sunlight. Once cured, it can be treated as waste and
disposed of in regular trash.

Preparation Before Printing
Being prepared is key for success! As you plan to implement this new workflow, check
all the supplies and inventory you may need or desire for a seamless workflow.

Design of the IBT
Once the intraoral scans of the patient are submitted to a dental-design service/lab, the IBT is designed and provided in STL file format by the dental-design service/lab
Bring the designed STL files to RayWare. Position the Intaglio surface of the IBT away from the print platform, with the occlusal surface/base of the design lying flat on the print platform.
Select “SprintRay IDB 2” resin setting for print-setting and use 100-micron thickness.
Ensure Resin Tank is fully secured and filled to the recommended Resin-Level.
Ensure the Print Platform is clean, dry, securely placed, and locked on the platform arm
Washing and Drying
After your IBT has been printed successfully, it must be washed using Isopropyl Alcohol (IPA) with a concentration of 91% or higher before being post-cured. SprintRay highly recommends Pro Wash/Dry for your cleaning process; however, if you don’t have access to a Pro Wash/Dry yet, you may allocate a separate Ultrasonic bath dedicated to post-print washing with IPA, or alternatively, a dish for soaking along with a Soft/Medium bristle brush to manually clean your prints in IPA. Ensure NOT to immerse the Try-in Denture for more than 10 min in the IPA bath.
Remember: IPA is highly flammable! Please keep it away from heat sources, sparks, and
Ensure that your IBT is completely dry before the next step; if not, use
compressed air to dry your IBT rapidly.
Remove the IBT from the Print Platform.
Next, the printed IBT needs to be properly post-cured using a Pro Cure to maximize strength and accuracy and comply with FDA standards.
All the post-curing settings are preset in Pro Cure 1 and Pro Cure 2 units.
