3D printing safety at home

Key Takeaways

• 3D printing at home carries safety risks, particularly with regards to materials and emissions
• Reliable information on 3D printer safety is scarce, and best practices are not always easy to identify
• Using a tent, HEPA filters, and charcoal filters can help minimize risks, but require proper validation and maintenance
• Passive monitors can be used to test for VOCs and other health hazards, but must be from a trusted source and properly calibrated

Introduction to 3D Printing Safety at Home

3D printing has become increasingly popular, with many engineers and enthusiasts using desktop machines at home. However, this convenience comes with safety risks, particularly when working with polymer filaments and resins used in fused deposition modeling (FDM) or stereolithography (SLA). According to the American Society for Testing and Materials (ASTM), the particulate emissions from FDM printers can be as high as 10-20 billion particles per minute, posing a significant health risk.

Reliable Information on 3D Printer Safety

A recent panel on AM safety at the Additive Manufacturing Users Group (AMUG) conference highlighted the need for reliable information on 3D printer safety. Panelists, including Qian Zhang, an environmental engineer with the Institute for Sustainable Infrastructure, and Paul Bates, senior lead for training and certification at ASTM, offered advice on minimizing risks. Zhang recommended using a tent to contain emissions and giving it time to settle before opening it, as well as using a webcam to monitor the first layers of a new build. Bates emphasized the importance of proper validation and maintenance of filters and passive monitors.

Minimizing Risks at Home

To minimize risks when 3D printing at home, it is essential to follow best practices, such as using a tent, HEPA filters, and charcoal filters. Additionally, passive monitors can be used to test for VOCs and other health hazards. However, it is crucial to ensure that these monitors are from a trusted source and properly calibrated. According to the Environmental Protection Agency (EPA), the use of HEPA filters can reduce particulate emissions by up to 99.97%.

Bottom Line

In conclusion, 3D printing at home carries safety risks that must be taken seriously. While reliable information on 3D printer safety is scarce, following best practices, such as using a tent, HEPA filters, and charcoal filters, can help minimize risks. It is essential to prioritize safety and take a proactive approach to minimizing risks, rather than relying on DIY solutions or untrusted sources. By doing so, 3D printing enthusiasts can enjoy the benefits of this technology while protecting their health and safety. With proper precautions and maintenance, 3D printing can be a safe and enjoyable hobby for enthusiasts of all levels.
