Lost wax casting resin 801

Lost wax casting resin 801

PRODUCT DETAILS

From retailers and designers who produce custom jewellery to large-scale foundries, jewelers can use Dayoude brand cast resins to expand their business.The high precision and smooth surface finish of Dayoude casting series resin allows you to go directly from design to production.

Features

801# Lost wax casting photosensitive resin is a blue casting resin with a wax content of 50%, complete combustion, no ash, and low expansion. It supports a variety of paraffin casting conditions and is compatible with high-quality gypsum to enhance the excellent effect of using gypsum outsourcing to cast jewelry.

Moreover, due to the addition of a special curing agent, the 801-type photosensitive resin has excellent hardness and rigidity, and can print ultra-fine gold and silver jewelry very well.

RECOMMENDED PRINTING PARAMETERS

Notice：

Material properties depend on the equipment light source, printing parameters, ambient temperature, post-processing, etc.

The final effect depends on the actual use of the user, this table is for reference only.

About operation

Printing

Before use: 

Shake the liquid resin evenly before use，Please wear gloves to clean the resin tank and the molding platform and keep the bottom of resin tank in light transmission.

When using:

Pour the 801 resin into the resin tank of the 3D printer, and import the dental model into the printer for printing.

After use:

After printing, please use the matching tools for post-processing, including blade, diagonal pliers, tweezers, containers, gloves; ethanol (≥95%).

Washing

Remove the custom tray from the build platform and soak in IPA(isopropanol) or ethanol(≥95%) to remove the extra resin. Use an ultrasonic cleaner if necessary. Please be aware that IPA and ethanol must NOT be placed directly in the tank of the ultrasonic cleaner.

Removing Supports

Manually snap off or use a flush cutter to snip away the support structure from the printed model. Using the flush cutter, cut the supports as close as possible to their attachment points on the model. Be careful not to nick the model itself, as this can cause pitting that may be difficult to remove during sanding.

Post-curing

For post-curing, the curing energy and curing time depends on the post-curing unit. For example, a good surface hardness can be achieved by 10 minutes of post-curing using a 36W (12WCCFL + 24W LED) UV curing box at 405nm or using Formlabs FormCure curing box at 405nm at 60°C for 15 minutes.

Polishing

Polish the surface using polishing paper or a rotary tool with a buffing attachment. Do not finish the print with mineral oil after sanding.

Casting

 01、Try to make the wall thickness of the model thinner, and not too thick.

02、Using the three-dimensional casting gypsum powder of the American SRS and Hunter brands.

03、The printed model must be cleaned and the model must be cured twice. The surface of the model and the mold on the inner wall of the non-stick plaster powder must be dry.

04、After wrapping the model in plaster, leave it for 24 hours. After the gypsum has dried to be free of moisture, it is then calcined. Direct sintering without drying will cause the gypsum to crack.

05、Heat the muffle furnace to 500-600°C, then put it in the plaster mold, heat it to 780-850°C and keep it for 4 hours (it is recommended to keep the heat preservation for 2 hours after turning the plaster mold for 2 hours, the wax mold will be sintered more evenly and cleanly)

06、After sintering, take out the plaster mold from the high temperature furnace and pour the metal.
