How to Dispose of 3DResin Waste
The utilization of 3D printing technology in a prosthetic laboratory streamlines and accelerates numerous processes. Alongside the benefits of this technology, certain risks and challenges arise. As we know, every liquid form of 3D printing resin is hazardous, so it’s incredibly important to consciously adhere to safety procedures and comply with waste disposal guidelines.
During the 3D printing process using resin, both empty bottles, protective gear, cleaning materials, and failed prints pose a certain risk as hazardous waste. Therefore, it’s necessary to treat them appropriately to ensure environmental and user safety. There are several proven methods for effective resin disposal worth considering.
Disposal of waste must comply with regulations. It’s advisable to contact local waste management or recycling centers to determine the proper disposal options for completely cured 3D resin waste.
Always refer to the Safety Data Sheet (SDS) as a reliable source of information on resin 3D safety, storage, and usage.
The general rule is for resin residues and materials contaminated with it to be fully cured, either by direct sunlight exposure or in a polymerization chamber. While such waste may not be suitable for recycling, it significantly reduces the negative impact on our environment.
In the case of liquid resin or alcohol-saturated solution after cleaning prints, which hasn’t been treated (you’ll find out how to do this from a separate article), contact a specialized company dealing with hazardous waste disposal such as solvent-based paints, enamels, and lacquers.
Do’s
- Use personal protective equipment when handling 3D resins!
- Cure remnants after printing, even used gloves or cleaning agents.
- If necessary, contact a local waste management or recycling center.
- Recycle alcohol used for cleaning prints.
Don’ts
- Don’t touch uncured prints or resin without nitrile gloves!
- Don’t pour liquid resin residues down the drain.
- Don’t dispose of uncured resin in municipal waste.
- Don’t pour alcohol used for cleaning prints down the drain.
