Product Introduction:
Name: 3D Printing Lost Wax Casting Photosensitive Resin (High Wax)
Model: 803
Color: Yellow
Packaging: Bottled
Specifications: 500g/1000g
Introduction:
Suitable for printing delicate wax models for gold and silver wire, jewelry, and other applications in the jewelry industry. This white wax-like casting resin offers high precision and excellent toughness.
Compatible Printers:
LCD 3D printers and DLP 3D printers with an LED light source wavelength of 365nm-405nm.
Product Features:
1. 803 lost wax casting photosensitive resin contains 30% wax, burns completely, is ashless, and has low expansion. It supports a variety of paraffin wax casting conditions and is compatible with high-quality gypsum, enhancing the excellent results of gypsum-coated jewelry.
2. It offers excellent hardness and rigidity, with high green strength ensuring excellent shape retention for fine lines and other delicate patterns.
3. The new formula features adjusted viscosity and reduced fluidity, making it particularly suitable for low-energy curing LCD devices, with an ultra-fast curing speed of 1 second for black and white LCD screens.

Note: The above values may vary depending on part geometry, print settings, temperature variations, and post-curing. Therefore, users must test the product before use to ensure that it meets their end-use performance requirements. The above values are typical and are not considered binding material specifications or guarantees unless expressly agreed to in writing. Final results will depend on actual user experience; this table is for reference only.
Instructions:
01 Printing
Before Use: Shake the liquid resin well before use. Wear gloves when cleaning the resin tank and build platform, ensuring that the bottom of the resin tank is transparent to light.
During use: Pour 803 resin into the 3D printer’s resin tank, then load the jewelry model into the 3D printer for printing.
After use: Please use the included tools for post-processing, including a blade, diagonal pliers, tweezers, a container, gloves, and ethanol (≥95%).
02 Washing
Remove the printed model from the build platform and soak it in IPA (isopropyl alcohol) or 95% ethanol to remove excess resin. If necessary, use an ultrasonic cleaner. Be careful not to place IPA or ethanol directly into the ultrasonic cleaner’s tank.
03 Support Removal
Manually break off or use pliers to cut support structures from the printed model. Using pliers, cut the supports as close to the model surface as possible. Be careful not to scratch the model itself, as this will cause spots that are difficult to remove during sanding.
04 Post-Curing
For post-curing, the curing energy and curing time depend on the post-curing unit. For example, good surface hardness can be achieved using a 36W (12W CCFL + 24W LED) 405nm UV curing chamber or a Formlabs FormCure curing chamber at 405nm at 60°C for 15 minutes.
05 Polishing
Use polishing paper or a polishing wheel to polish the surface. Do not use paraffin wax for final polishing after sanding.
06 Precision Lost Wax Casting Method for Jewelry:
① When printing the model, keep the wall thickness as thin as possible, not too thick.
② It is recommended to use SRS\Hunter brand 3D casting plaster powder from the United States.
③ The printed model must be cleaned thoroughly and the model must be post-cured. Ensure that the surface of the model is dry and non-sticky so that it will not stick to the inner wall of the plaster mold after being embedded in plaster.
④ After embedding the model in plaster, let it sit for 24 hours. Wait until the plaster is completely dry and free of moisture before calcining. Directly sintering a wet plaster mold will cause cracking. ⑤ Heat the muffle furnace to 500-600°C, then place the plaster mold in the mold. Heat to 780-850°C and hold for 2-4 hours. (It is recommended to sinter the front of the mold for 1-2 hours, then flip it upside down and sinter it for another 1-2 hours to ensure a more even and clean sintering of the wax mold.)
⑥ After sintering, remove the mold and use a high-pressure air gun to blow away any impurities remaining in the mold cavity. Then, vacuum the remaining impurities. Finally, pour in the molten metal to be cast.
