Zero Resin Instructions for Use

1- Indented Use

Powerresins Zero Dark resin was developed especially for the direct casting of highly detailed jewelry. 

This resin shows almost no shrinkage with a shrinkage rate of less than 1%. It ensures good casting quality while not shrinking after 3D printing.

You can use Powerresins Zero Dark resin for filigree items as well as surface items.
 

Powerresins Zero Dark resin can be used for all types of DLP/LCD curing 3D printers. It has fast curing properties depending on the 3D printer used.

 

2- Contraindications

Powerresins Zero Dark resin should not be used for any purpose other than jewelry applications. Any deviation from these instructions for use may adversely affect the chemical and physical quality of the 3D product. In case of an allergic reaction, please consult a medical doctor.

3- Safety Instructions

To ensure optimum further processing, please read the information contained in the instructions for use carefully. Incorrect use and failure to observe the information can have a detrimental effect on quality. Nitrile gloves, goggles, and a jacket should be worn 
as a means of protection when working with the resin.
 

The safety instructions and precautions specified in the operating instructions and safety data sheet shall apply to the removal of liquid resin and uncured resin from the model.
 

4- Side Effects and Precautions

6- Production Steps

Processing:
Power Resins Zero Resin is designed to work with all LCD and DLP 3D printers. See the Printer Settings section on powerresins.com for optimization databases.

Cleaning:
a. Allow the model to clean for 3 minutes in compartment 1 of the MEDIFIVE washer containing ethanol solution (96%). After the process is complete, dry the model with a spray air gun.

b. Allow the model washed and dried in compartment 1 to be cleaned in compartment 2 of the MEDIFIVE washer containing ethanol solution (96%) for 3 minutes. After the process is complete, dry the model with a spray air gun.

Do not exceed the 6-minute total cleaning procedure as this may cause deterioration of printed objects.

Hint: Resin residues can also be removed using a brush moistened with ethanol (96%).

7- Post-Curing (Final Curing)

Power Resins Zero Resin does not require final curing. You can apply a direct casting process to 3D models.

8- Recommended Burnout Cycle

Power Resins suggestion for the casting process consists of three sections.

1. The cleaning part; 

The sample rings I sent you are already cleaned.

2. Investment process part;

We suggest Ransom & Randolph Plasticast for investment powder. It is optional, you can use what you have at the moment.

Adding boric acid and calcium nitrate to the investment solutions; is optional. Our tests show us that with these supplements, the casting quality has improved.

Hot water bath; also optional. Again, this step helps for better casting results.

3. Burnout process part; 

please use option 2 in the earlier email. As it follows;          

Set the furnace temperature to 150⁰C.

Load the flask into the furnace with its face downwards at 150⁰C temperature.

Hold for 3 hours at 150⁰C

Ramp to 550⁰C in 30 minutes.

Hold at 550⁰C for 4 hours.

Ramp to 600⁰C in 30 minutes.

Hold at 600⁰C for 30 minutes.

Ramp to 650⁰C in 30 minutes.

Hold at 650⁰C for 30 minutes.

Ramp to 700⁰C in 30 minutes.

Hold at 700⁰C for 30 minutes.

Ramp to 750⁰C in 30 minutes.

Hold at 750⁰C for 30 minutes.

Ramp to 600⁰C in 1 hour.

Hold at 600⁰C for 1 hour.

Remove the flask from the furnace and blow it with compressed air thoroughly then reload it back in the furnace with its face upwards for gases to escape for 1 hour at 600⁰C.

Cast the flask.

Blowing compressed air through the flask is very important. In fact, you can open the furnace hatch during the burnout process a couple of times for the oxygen flow in order to have better burnout.
