SprintRay OnX Tough



SprintRay OnX Tough is a next generation hybrid ceramic, class II resin designed for the fabrication of dental prosthetics. Created using proprietary NanoFusion™ technology, OnX Tough delivers unparalleled durability and a smooth surface finish that mimics natural enamel with optimal translucency.

The resin allows for a highly efficient in-office workflow with easy post-processing and characterization and can now be cleaned with ProWash. Simple-tear supports separate with the flick of a wrist. With no extra mixing (or rolling) required, OnX Tough delivers extraordinary strength and lab-quality aesthetics. 


Key Benefits

  • 5X tougher than first generation technology
  • Easy to post-process and characterize
  • A smooth surface finish and optimal translucency that mimics natural enamel

Quick tips

  • Print thickness recommendation: 100 micron
  • Thoroughly mix before every print for increased print success rate
  • Use OptiGlaze™ kit by GC for characterization

The device specifications have been validated using the software, printers, and process parameters specified in this document. Any other printers, operation software and post-printing processes will be outside of the device specifications. Users shall follow this document to use the device.



The SprintRay OnX Tough 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 for use.


  • The SprintRay OnX Tough resin is non-toxic in solid form, and it is classified as a 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. If contact with skin, wash thoroughly with soap and water. If skin sensitization occurs, discontinue use. If dermatitis or other symptoms persist, seek medical assistance.
  • Avoid inhalation or ingestion. High vapor concentration can cause headache, irritation of eyes or respiratory system. Direct contact with eyes may cause possible corneal damage. Long-term excessive exposure to the material may cause more serious health effects. Monitor air quality per OSHA standards.
  • Eye Contact: Immediately flush eyes with plenty of clean water for at least 20 minutes and consult a physician. Wash the contacted area thoroughly with soap and water.
  • Inhalation: In case of exposure to a high concentration of vapor or mist, remove person to fresh air. Give oxygen or artificial respiration as required
  • Ingestion: Contact your regional poison control center immediately.


  • When washing the device with solvent or grinding the device, it should be in a properly
    ventilated environment with proper protective masks and gloves.
  • Recommended storage conditions for unprocessed SprintRay OnX Tough are at 15 – 25 C (60 -77 F) and avoid direct sunlight.
  • Keep the container closed when it is not in use.
  • Expired or unused SprintRay OnX Tough should be completely cured or polymerized prior to disposal.
  • Product shall not be used after expiration date.
  • For activation and complete polymerization of the SprintRay OnX Tough please follow the steps involved in “Fabrication of device” and “Post-curing”.



Fabrication of Device

1. Design of the Device

The Device is designed and provided in STL file format by the dental-design service/lab,using intraoral scans of the patient.

2. Printing


  • Upload the STL file to RayWare. Position the device with the occlusal surface facing the print platform (intaglio facing away from the print platform) and the occlusal plane parallel to the print platform. (pictured above)
  • Add supports.
  • Select the “SprintRay OnX Tough” resin setting for print-setting and use 100-micron layer 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

3. Support Removal

After your device has been printed successfully, you need to remove it from the print platform using the Part-Removal-Tool, followed by removing all the supports using a flush cutter or round diamond disc. Try to cut as close as possible to the device to minimize the smoothening and finishing procedure.

4. Washing and Drying

Next step is to clean and wash the device from excess uncured-resin residue. Use >91% IPA to wash the device using any of the following methods:

  • Hand spray and wiping with dry towel
  • Sonication
  • Pro Wash/Dry

Remember: IPA is highly flammable! Please keep it away from heat sources, sparks, and flames.
Ensure that your prints are completely dry before the next step; if not, use compressed air to dry your parts rapidly.

5. Post Curing

Use below recommended post-curing equipment to maximize strength, accuracy, and complete polymerization to comply required standards:

  • If using ProCure, you need to post-cure for 60 minutes at 60 degrees C
  • If using ProCure 2, choose SprintRay OnX Tough setting for post-curing.



Remove any excess support-nubs by using a lab carbide burr.



Use medium and fine polishing wheels to polish and shine the device. Wash and clean the device with a brush using soap and warm water.
