Instructions For Use

Resin for 3D printing of permanent single crowns, inlays,
onlays and veneers. SprintRay Crown is used within a dental
CAD/CAM workflow and should only be used with compatible 3D printers and post-curing devices. The Processing Requirements section below includes a list of requirements for the use of this device.

CAUTION: Federal law restricts this device to sale by or on the order of a dentist. For professional use only – Rx Only. SprintRay Crown is a light-cured, methacrylate-based resin used in 3D printers for the production of permanent crowns, inlays, onlays and veneers. SprintRay Crown is suitable for restoration of occlusal surfaces. SprintRay Crown is cured externally to the patient by light sources within the 3D printer and the post-curing device described below.


Indications for Use

SprintRay Crown is indicated as an indirect restorative for both anterior and posterior restorations, including occlusal surfaces. The SprintRay Crown material is used for fabricating permanent restorations such as inlays, onlays, veneers and full crown restorations.


Known allergy to one or more ingredients. In cases of doubt, the allergy should be clarified and ruled out based on a specific test prior to the application of this product. SprintRay Crown should not be used for purposes other than the production of permanent single crowns, inlays, onlays and veneers. Any deviation from these instructions for use can have negative effects on the chemical and physical quality of objects made from SprintRay Crown.

Safety Instructions

SprintRay Crown is produced and tested according to the stringent quality standards. In order to ensure optimum further processing, please read the information contained in the instructions for use carefully. The improper use of SprintRay Crown and failure to follow information can have a detrimental effect on the quality of objects produced from SprintRay Crown 3D resin. Nitrile gloves, safety goggles and a coat must be worn as a means of protection when handling the resin and the object that has not been post-cured. Conventional medical gloves do not offer any lasting protection against the sensitizing effect of methacrylates. If the product comes into contact with the glove, take the glove off and discard it, wash your hands immediately with water and soap and put on a new glove. Consult a physician in the event of an allergic reaction. The safety and care instructions set down in the SprintRay Crown instructions for use and safety data sheet shall apply to the handling of liquid resin and printed objects that have not been post-cured (objects in the “green condition”). A dust mask must be worn too due to potential dust formation while the printed objects are being processed

Unused resin in the resin tank has to be stored in the closed printer which protects the resin from light, or in an alternative dark, dry location. It must be ensured that the temperature does not drop below +4 °C and does not exceed +28 °C! The minimum shelf life date printed on the product must be observed.

CAUTION: Expected results cannot be guaranteed if materials which have exceeded their minimum shelf life date are used or if storage instructions are not followed. The completely cured print objects must be stored at room temperature and protected from sources of light


Processing/Printing Requirements



  • Create the object (STL-file) using a commercial CAD software, which is intended for dental applications.
  • When designing, observe the requirements for minimum wall thicknesses for finished restorations:
    • Minimum wall thicknesses anterior teeth 1.0 mm
    • Minimum wall thicknesses posterior teeth 1.0 mm
    • Minimal wall thickness, cervical 1.0 mm
    • Minimal wall thickness, veneer shell 0.5 mm

Nesting & preparation for printing

• Import STL file
• Manual/Automatic rotation and placement
• Optimal orientation: horizontal, occlusal plane facing the build platform
• Manual/Automatic generation of supports


SprintRay Crown has been verified and validated in combination with various system components (3D printers, cleaning devices and post-curing devices). We are constantly working on further qualifications. You can find these compatible system components on our website https://sprintray.com/ Please pay special attention to the build platform and resin tank materials as noted in the compatibility matrix.

WARNING: This material is suitable for manufacturing highly reliable dental products only when using approved compatible systems including the material parameters. If unapproved components or material parameters are used, there is a high risk of unreliable and / or unusable products which may endanger the safety of the user.

Environmental Conditions

  • Temperature range between 18 °C and 28 °C

Printing Parameters

  • Layer thickness: 50 or 100 μm
  • Optimal orientation: horizontal orientation, occlusal plane facing the build platform.

Necessary tools, equipment and materials for post-processing

• Print removal tool
• Unheated ultrasonic bath
• Ethanol solution 96%
• Spray bottle with 96% ethanol solution
• Cutting wheel or side cutters (for support structure removal)
• Sandblaster 1.5 bar
• Glass bead blasting material 50 μm (e. g. Perlablast® micro, REF 46092/54302)


The following instructions contain details of a validated workflow for the 3D printing process with a compatible 3D printer. The ideal working temperature of SprintRay Crown is in the temperature range between 18 °C and 35 °C. Before use, he resin must be homogeneous. Before the first use, the material has to be shaken well about 2 min. When decanting, make sure that the printing resin is exposed to daylight for as short a period of time as possible. Mix the resin in the cartridge / resin tank if a transparent layer is visible on the surface. For further processing – selecting the resin, material parameter, setting up the print job – as part of the printing process, follow the respective printer instructions for use.

CAUTION: The device specifications have been validated using the software, printers, and process parameters specified in this document. Any unauthorized changes to the process equipment, parameters, or software may result in a device that is out of specification and not covered under the FDA clearance. Users shall follow this document in order to use the SprintRay Crown. Users shall also follow the instructions for use documents and all maintenance requirements for the equipment identified in this document.


Cleaning and Preparation for Post-Curing

On completion of printing, the print objects are released from the build platform using the print removal tool. The print object should be cleaned in two steps with ethanol (96%) using an ultrasonic bath.

CAUTION: Never fill ethanol directly into the ultrasonic bath; place it in the recommended container in the ultrasonic bath filled with water. Use an explosion-proof ultrasonic bath.

  1.  Clean the print object for 3 min in a reusable ethanol solution (96%) using an unheated
    ultrasonic bath.
  2. The precleaned object must be cleaned thoroughly for 2 min using a fresh ethanol (96%)
    solution with the aid of an unheated ultrasonic bath.
  3. The print object is then removed from the ethanol bath and sprayed with additional ethanol (96%) in order to fully rinse off any remaining resin residue.
  4. Tip: Resin residues can also be removed using a brush soaked in ethanol (96%).

CAUTION: The entire cleaning process should not take longer than 5 min as this could otherwise have a detrimental effect on the printed objects (swelling of the object with ethanol).

After cleaning, the print object is dried using compressed air under an extraction unit. If there is liquid resin still adhering to the surface of the object, this can be completely removed by spraying again with ethanol (96%) and re-drying.


Preparation for post-curing

  • Remove the support structure with the help of a cutting wheel or side cutters.
  • Remove the white layer using a glass bead blasting material 50 μm (e. g. Perlablast® micro) at a maximum blasting pressure of 1.5 bar.
  • Check for fit and finish the objects completely. Finishing and contouring can be per-
    formed using carbide cutter or diamond grinding stones.


Post-Curing Process

The final properties of the printed object depend on the post-curing process. Please note the assignment of the light curing device to the 3D printer of the approved system components. The post-curing of the object is done without use of a model, then allow to cool for 3–5 minutes or until the object feels cool.



Use the Pro Cure for 2 cycles at 20 min at 20°C, rotating once after the first cycle is complete.


For the Pro Cure 2, use the predefined setting in your SprintRay materials list.


Supplementing of printed objects

Defects (e. g. missing contact points) can be supplemented with the resin or with commercially available composite veneering materials.

Supplementing with resin

  • Blast the areas to be supplemented with aluminum oxide – pressure 1.5 bar and particle size 110 μm.
  • Put some liquid SprintRay Crown on the object.
  • Put it under light for a short time (2 x 20 min in the SprintRay Pro Cure)
  • If more material has to be applied, put additional liquid SprintRay Crown on the last layer and then put it again under light for a short time (2 x 20 min in the SprintRay Pro Cure)
  • Final curing of the Objects carried out as described in the section "Post Curing Process"

Supplementing with veneering material

The printed objects can be supplemented with commercially available composite veneering
materials (e. g. VITAVM LC*, Vita Zahnfabrik, und VITAVM LC flow*, Vita Zahnfabrik). The
manufacturer's instructions for use must be observed.




Polish the surface of the objects with pumice stone and polishing compound. Avoid over-
heating of the restorations during polishing. Optimal surface quality is achieved by polishing after post-curing.
Tip: Optionally, the surface of the objects can be coated with light-curing glaze (e. g. Vita ENAMIC GLAZE *, Vita Zahnfabrik or GC OPTIGLAZE *, GC). Pay attention to the manufacturer`s instructions for use.


Individualization (optional)

Instead of polishing the surface, the post-cured objects can also be individualized with
composite stains or veneering materials.

  • Commercially available composite stain materials (e. g. VITA ENAMIC STAIN*, Vita Zahn-
    fabrik and GC OPTIGLAZE Color*, GC) can be used for individualization of the post-cured VarseoSmile Crownplus restoration. The manufacturer's instructions for use must be observed. Individualization with veneering materials
  • Commercially available composite veneering materials (e. g. VITAVM LC*, Vita Zahnfabrik and
    VITAVM LC flow*, Vita Zahnfabrik) can be used for individualization of the restoration. The
    manufacturer's instructions for use must be observed.
    Veneer shells
  • Commercially available light-curing veneering composites can be used to attach the
    post-cured veneer shells to the metal framework (e. g. VITAVM LC, VITAVM LC flow, Vita

Basic work steps

  •  Condition the surface of the metal framework.
  • Cover the metal framework with opaquer.
  • Sandblast the inside of the veneer shell and clean the veneer shell from dust.
  • Inner surface conditioning of the veneer shell.
  • Applying the veneering material to the inside of the veneer shell or the metal framework.
  • Positioning of the veneer shell on the metal framework and remove the excess with a brush or an instrument.
  • Carry out the polymerization according to the instructions of the veneering material manufacturer.
  • Finally, the surface of the veneer shell should be polished or customized with composite stains (see section "Polishing" or "Individualization").


Fully cured objects made from SprintRay Crown can be easily cleaned and disinfected. Steam cleaning (e. g., with Triton SLA) is possible. Disinfection in the immersion bath (e. g. ethanol 96% or MD 520* impression disinfectant, Dürr Dental Co.) is also possible. Follow manufacturer's instructions.



Attachment to tooth stump

The finished permanent restorations can be attached using self-adhesive cements (e. g. RelyX Unicem*, 3M Espe) or composite cement with a primer (e. g. Variolink Esthetic DC* and Monobond Plus*, Ivoclar Vivadent). Observe the instructions for use of the luting agent.


The cured, separated material (base plate, support structure) can no longer be used. Cured material can be disposed of as domestic waste. Unused resin or ethanol used for cleaning with resin residues must be disposed of via the local waste disposal authority or a hazardous waste collection point stating the safety data sheet.
