Instructions for use
VarseoWax CAD/Cast
Resin for the 3D printing of burnout objects.
1. Intended use / Indication
VarseoWax CAD/Cast is a light-curing resin for the 3D printing of
burnout frames such as partial dentures, crowns and bridges, inlays,
onlays, and veneers. It is restricted to use in dental applications and
may only be used by dental staff. 3D-printed objects made of Varseo-
Wax CAD/Cast are manufactured using digital (CAD/CAM) processes.
These objects are more stable than objects made of wax. They are
burnable without leaving residue, and are very well suited for the cast-
ing process for dental restorations.
2. Contraindications
VarseoWax CAD/Cast is exclusively intended for the manufacture of
burnout objects. Any deviation from the instructions for use can have
a negative effect on the chemical and physical qualities of VarseoWax
CAD/Cast. VarseoWax CAD/Cast may not make direct contact with the
patient (e.g. fitting in the patient's mouth)! In case of allergic reaction
or intolerance occurs, please contact a practitioner / doctor.
3. Safety instructions
VarseoWax CAD/Cast is produced and tested according to the most
stringent quality standards. In order to ensure optimum further pro-
cessing, please read the information contained in the instructions for
use carefully. Improper use and failure to observe the information can
have a detrimental effect on the quality. Nitrile gloves, goggles and a
coat must be worn as a means of protection.
Instructions on how to handle plastic parts made of
VarseoWax CAD/Cast
The safety instructions and precautions set down in the VarseoWax
CAD/Cast instructions for use and safety data sheet shall apply to the
handling of liquid resin and 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.
Depending on the furnace temperature, combustion gases that are
harmful to health may form while the invested objects are being pre-
heated and burnt out. A sufficiently high temperature in the preheat-
ing furnace helps the cured plastic to combust completely to carbon
dioxide, water and nitrogen oxides.
4. Side effects and precautions
Precautions / Protection
It is essential that protective clothing be worn when handling VarseoWax
CAD/Cast. Safety goggles and nitrile gloves must be used. Further infor-
mation on handling the product can be found in the safety data sheet
and also downloaded from the BEGO Download Centre at www.bego.com.
However, we cannot completely rule out the possibility of personal reac-
tions to individual components in isolated cases. In such cases, the user
should discontinue use of VarseoWax CAD/Cast.

5. General information on handling
Delivery
VarseoWax CAD/Cast is supplied in light-tight, sealed bottles.
Filling quatity:
• REF 41136 = 1 kg
• REF 41137 = 250 g
* Partial denture: Investing with VarseoVest P
plus
ting with VarseoVest C&B.
VarseoVest P and VarseoVest C&B are the phosphate-bonded shock-heat
plus
precision investment materials that has been specially developed and
coordinated to casting 3D-printed objects.
Storage
VarseoWax CAD/Cast must be stored in the original sealed bottle at
room temperature (approx. 22 °C) in a dark, dry place. It must be en-
sured that the temperature does not drop below +5 °C and does not
exceed +35 °C! The minimum shelf life date printed on the product
must be observed. Perfect processing cannot be guaranteed if ma-
terials which have exceeded their minimum shelf life date are used.
6. Other information
In addition, VarseoWax CAD/Cast is especially well-suited for further
applications involving burn-out casting material (e.g. jewellery). When
used in this manner, the material may only be used by specialist per-
sonnel.
7. Processing
The best fit results are obtained by aligning the objects horizontally
atop the build platform. The printing settings can be found in the
instructions for use for the respective equipment.
Please wear protective gloves (nitrile gloves), protective clothing, gog-
gles and / or face protection during processing!
The ideal working temperature range for VarseoWax CAD/Cast is be-
tween 20 and 30 °C. Before decanting in the clean resin container
(cartridge / resin tub), the material must be vigorously shaken for
approx. 2 minutes. When decanting, make sure that the printing resin
is exposed to light for as short a period of time as possible.
For further processing – selecting the resin, setting up the print job –
as part of the printing process, the instructions for use of the respec-
tive 3D printer must be adhered to. Before the start of each printing
process, VarseoWax CAD/Cast must be inspected. If a transparent
layer is visible on the surface, it must be mixed until homogeneous.
Insufficient mixing can lead to deviations in the colour of the printing
resin.
In principle, VarseoWax CAD/Cast should be processed on 3D printing
systems that use a wavelength of between 385 and 405 nm.
The verified, compatible 3D printing system components (3D prin ters,
cleaning devices and post-curing devices) can be found on our web-
site https://www.bego.com/3d-printing/compatibility-overview/
Note: All processing methods listed in the instructions for use serve
as examples.
Subsequent processing
Upon 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.
Note: 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 %) in an unheated ultrasonic bath.
2. Next, fully clean the objects for 2 minutes in an ultrasonic bath,
using a fresh ethanol solution (96 %).
3. Remove the print object from the ethanol bath and dry with com-
pressed air, using suction if possible.
4. Inspect the objects for resin residue (shiny areas) and remove these
by spraying with ethanol (96 %).
Tip: Resin residues can also be removed using a brush soaked in
ethanol (96 %).
The entire cleaning process should not take longer than 5 minutes as
this could otherwise have a detrimental effect on the objects.
Finishing
Remove support structure using either a cutting wheel or side cutters. It
must be ensured that the printed object is not deformed!
The completely cleaned print objects must be post-cured to attain the
required material properties. The final properties of the print object
depend on the post-curing process. The final material properties are
achieved using light polymerisation units with the following perfor-
mance data: two xenon stroboscopic lamps, flash frequency 10 Hz, light
spectrum 360–700 nm (e.g., BEGO Otoflash) or one xenon stroboscopic
lamp, flash frequency 20 Hz, light spectrum 390-540 nm (e.g., HiLite
Power, Heraeus Kulzer).

8. Storage and transportation of printed objects
Post-curing is strongly recommended in the case of extended storage
and transportation times! The fully cured print objects can be ideally
stored at room temperature away from light, and transported in a suit-
able lightproof transport box!
9. Cleaning and preparing the cast object
Grinding dust can easily be completely removed from fully cured
VarseoWax CAD/Cast objects before they are invested for casting
purposes by holding them under running water and blowing them off
again.
Please prepare the created cast object for casting as per the den-
tal casting technology specifications. Within the context of further
processing, please follow the instructions for use and the safety in-
structions for the investment material used*, as well as the setting
recommendations for the mixer, furnace and casting unit used.
10. Disposal
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.
