Storage
This product must be stored in the original sealed bottle, or in the car-
tridge at room temperature (approx. 22 °C) in a dark, dry place. 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.
Notice: 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.

6. Processing requirements
1. Design
• Create the object (STL-file) using a commercial CAD software, which is
intended for dental applications.
• When designing, observe the requirements for minimum wall thick-
nesses for finished restorations.
Notice:
Crowns, inlays, onlays and veneers
Minimum wall thicknesses anterior teeth
Minimum wall thicknesses posterior teeth
Minimal wall thickness, cervical
Minimal wall thickness, veneer shell
2. Nesting & preparation for printing
plus . • Import STL file
• Manual / Automatic rotation and placement
• Optimal orientation: horizontal, occlusal plane facing the build
platform
• Manual / Automatic generation of supports
3. Printing
VarseoSmile Crown plus 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://www.bego.com/3d-printing/compatibility-overview/
Please pay special attention to the build platform and resin tank mate-
rials as noted in the compatibility matrix.

WARNING: This material is suitable for manufacturing highly
reliable dental products only when using BEGO approved com-
patible 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.
Notice: It is important to follow the instructions for use and maintenance
instructions provi ded by the manufacturer for all system components.
4. Necessary tools, equipment and materials for post-processing
• Stainless steel spatula
• 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
REF 46092 / 54302)
7. Processing
The following instructions contain details of a validated workflow for the
3D printing process with a compatible 3D printer.
The ideal working temperature of VarseoSmile Crown
ture range between 18 °C and 28 °C. Before use, the resin must be homoge-
neous. 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.
Cleaning and preparation for post-curing
On completion of printing, the print objects are released from the build
platform using the spatula. The print object should be cleaned in two steps
with ethanol (96 %) using an ultrasonic bath.
Precaution: Never fill ethanol directly into the ultrasonic bath; place
it in the recommended container (REF 19621) 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. 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.
Tip: Resin residues can also be removed using a brush soaked in ethanol
(96 %).
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.

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.

This results in a further reduction of the already low remaining monomer
content. To do so, set the protective gas function to switch position 1.

Polish
Polish the surface of the objects with pumice stone and polishing com-

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.
