The Importance of an Enclosed 3D Printer & HEPA Filtration

Afinia 3D Printers are great for for educators, engineers, and hobbyists alike, and for good reason. They are affordable, easy to use, and create quality prints. Now, a recent study published by The Built Environment Research Group reinforces why the H400 and H800+ should be of high interest to makers of all kinds. Especially those who use, or plan to use, their 3D printers in enclosed spaces like classrooms, offices, or at home.

3D Printing and UFP Emission

Using a 3D printer inevitably creates UFPs (ultrafine particles). It’s important to note that UFPs are present in everyday life. For example, common household UFPs include animal dander, smoke (from cooking oils and/or tobacco), and dust. Although we are exposed to these emissions on a daily basis, the EPA suggests limiting exposure, especially in confined areas.

Both the Afinia H400 and H800+ 3D Printers have an enclosed design and HEPA filtration systems that help reduce exposure to these UFP emissions. When tested, the H800+ enclosure design reduced UFP emissions by 74%, and the HEPA filtration system reduced emissions by a whopping 91%. These design elements can help those who create using 3D printers do so in a safer manner.

Non-enclosed 3D Printers

If you currently own a 3D printer that is not enclosed, or does not have a HEPA filtration system, note that PLA filament has been shown to result in lower UFP emission than ABS.
