What are the best practices and tips for storing and handling vat photopolymerization resin?

1 Choose the right container

The first step to store and handle vat photopolymerization resin is to choose the right container. You should use a light-proof and airtight container that is compatible with the resin and has a label with the name, date, and safety information. Avoid using glass or metal containers that can break or react with the resin. You should also clean and dry the container before filling it with resin to prevent any dirt or moisture from affecting the quality of the resin.

3 Shake well before use

The third step to store and handle vat photopolymerization resin is to shake well before use. Resin can settle or separate over time, so you should shake the container vigorously for at least 30 seconds before pouring it into the vat. This will help to mix the resin evenly and ensure a consistent color and viscosity. You should also avoid shaking the container too close to the printer or the vat, as this can create bubbles or splashes that can affect the printing quality or damage the equipment.

4 Wear protective gear

The fourth step to store and handle vat photopolymerization resin is to wear protective gear. Resin can be harmful if it comes into contact with your skin, eyes, or respiratory system, so you should always wear gloves, goggles, and a mask when handling resin. You should also work in a well-ventilated area and avoid eating, drinking, or smoking near the resin. If you spill or splash any resin on yourself or the surroundings, you should clean it up immediately with paper towels and isopropyl alcohol.

5 Filter and reuse resin

The fifth step to store and handle vat photopolymerization resin is to filter and reuse resin. After printing, you may have some leftover resin in the vat or the tank that you can reuse for future prints. However, you should filter the resin first to remove any cured bits, dust, or debris that can affect the printing quality or clog the nozzle. You can use a fine mesh strainer, a coffee filter, or a specialized resin filter to filter the resin into a clean container. You should also label the container with the name, date, and level of usage of the resin.

6 Dispose of resin safely

The sixth step to store and handle vat photopolymerization resin is to dispose of resin safely. Resin is considered a hazardous waste that cannot be thrown away in the regular trash or poured down the drain. You should follow the local regulations and guidelines for disposing of resin safely and responsibly. You should also cure any resin waste before disposing of it, as this will make it less toxic and easier to handle. You can cure resin waste by exposing it to sunlight, UV light, or heat until it becomes solid and brittle.
