High Wax casting resin 802 1kg

Description

Product model: ZDS802 Casting Resin
Product introduction: 802 is printing dental casting photosensitive resin suitable for gold and silver jewelry
in the jewelry industry, wax crowns in the dental industry, steel wax models, etc. that require hardness.
Applicable printers: LCD and DLP 3D printers with LED light source wavelength 385nm-405nm.
Colour: Green
Features: Type 802 lost wax casting photosensitive resin is a green casting material with 55% wax content,
complete combustion, no ash, and low expansion. The printed wax model has clear details and excellent
hardness, which is tougher than 801. Support a variety of paraffin casting conditions, compatible with
high-quality gypsum, and improve the excellent effect of using gypsum outsourcing to cast jewelry. 802 is
tougher and more suitable for gold and silver jewelry and dental casting

Introduction to use steps:
01 Print
Before use: Shake the liquid resin well before use, please wear gloves to clean the resin tank and molding
platform, and keep the bottom of the resin tank transparent.
When using it:Pour 802 resin into the resin tank of the 3D printer, then import the jewelry model into the
3D printer for printing.
After use:Please use supporting tools for post-processing, including blades, diagonal pliers, tweezers,
containers, gloves, ethanol (≥95)
02 Washing
Remove the printed model from the build platform and soak in IPA (isopropyl alcohol) or 95% ethanol to
remove excess resin. Use an ultrasonic cleaner if necessary. Note, never place IPA and ethanol directly in
the tank of the ultrasonic cleaner.
03 Remove supports
Manually break off or use scissors to cut the support structure from the printed model. Using snips, cut
away as much support as possible as close to the surface of the model as possible. Be careful not to scratch
the model itself as this will cause spots which are difficult to remove during sanding.04 Post curing
For post-curing, the curing energy and curing time depend on the post-curing unit. Good surface hardness
can be obtained eg by using a UV curing oven at 36W (12W CCFL + 24W LED) 405nm or using a Formlabs
FormCure oven at 405nm for 15 minutes at 60°C.
05 Polishing
Polish the surface with polishing paper or a buffing wheel, do not use paraffin to finish after sanding.
06 Jewelry precision lost wax casting method:
1. Try to make the wall thickness of the printed model as thin as possible, not too thick.
2. It is recommended to use the three-dimensional casting gypsum powder of the American SRS/Hunter
brand.
3. The printed model must be cleaned and the model must be secondary cured. Make sure that the surface
of the model must be dry and non-sticky, and it will not stick to the inner wall of the plaster mold after it is
embedded in plaster.
4. After embedding the model with plaster, leave it for 24 hours. After the moisture in the gypsum is
completely dry and contains no moisture, calcination is started. Direct sintering of the gypsum mold that is
not dry will cause the gypsum mold to crack.
5. Heat the muffle furnace to 500-600°C, then put it into the stone high mold, heat it to 780-850°C, and
keep it for 2-4 hours (it is recommended to sinter the front of the plaster mold for 1-2 hours, and then turn
the stone mold upside down and then sinter it 1-2 hours to ensure more even and clean wax sintering)
6. After the sintering is completed, take out the plaster mold, first blow off the remaining impurities in the
cavity of the plaster mold with a high-pressure air gun; then use a vacuum cleaner to vacuum up the
remaining impurities. Finally, pour in the metal solution that needs to be cast.Package:500g/bottle, 1kg/bottle or according to customer needs.
