Navigating the World of 3D Printer Resin: Do's and Don'ts for Safe Handling and Disposal

Navigating the World of 3D Printer Resin: Do's and Don'ts for Safe Handling and Disposal


3D printing has revolutionized the way we bring ideas to life, offering unprecedented possibilities in prototyping, design, and manufacturing. However, with great power comes great responsibility, especially when it comes to handling and disposing of 3D printer resin. Resin, a liquid material used in stereolithography and other resin-based 3D printing technologies, requires careful attention to ensure both user safety and environmental sustainability. In this blog, we'll explore the do's and don'ts when dealing with 3D printer resin to help you navigate this essential aspect of the 3D printing process.

The Do's:

Wear Protective Gear:

Always wear appropriate personal protective equipment (PPE) when handling 3D printer resin. This includes gloves, safety glasses, and a long-sleeved shirt.

Work in a Well-Ventilated Area:

Use your 3D printer in a well-ventilated space or set up additional ventilation to reduce exposure to resin fumes. If you find yourself limited by the space you have to work with you could also try an air purifier. Phrozens air purifier absorbs harsh odours while quickly and quietly purifying the air. 

Follow Manufacturer Guidelines:

Adhere strictly to the manufacturer's recommendations and guidelines for handling, storage, and disposal. These guidelines are designed to ensure both the safety and optimal performance of the resin.

Dispose of Resin Waste Properly:

Dispose of resin waste in accordance with local regulations. This may involve curing the resin before disposal, using a resin recycling service, or taking it to a designated hazardous waste facility.

Store Resin Safely:

Store 3D printer resin in its original container, tightly sealed, and away from direct sunlight. Follow the recommended storage conditions to prevent contamination and degradation.

Use Appropriate Tools:

When working with 3D printer resin, use tools designed for resin handling, such as spatulasfunnels and containers. Avoid using tools that may react with or contaminate the resin.

The Don'ts:

Don't Pour Unused Resin Down the Drain:

Never pour unused resin or cleaning solvents down the drain. Resin can clog pipes and harm the environment. Instead, follow proper disposal methods, such as curing the resin and then disposing of it as solid waste.

Don't Mix Resins Unnecessarily:

Avoid mixing different types or brands of resin unless explicitly stated as compatible by the manufacturers. Incompatibility may result in compromised print quality or, in extreme cases, hazardous reactions.

Don't Store Resin Indefinitely:

Resin has a limited shelf life. Do not use expired resin, as it may result in failed prints or other complications. Always check the expiration date and use the resin within the specified timeframe.


As 3D printing technology continues to advance, responsible handling and disposal of 3D printer resin become increasingly crucial. By following these do's and don'ts, you can ensure a safe and environmentally friendly 3D printing experience. Always prioritize your safety and the well-being of the environment, and stay informed about the latest guidelines and best practices in 3D printer resin management.
