Manufacturing might benefit greatly from 3D printing. It is now possible to have 3D printers in our home workshops and school classrooms, allowing more people to engage in 3D printing as a pastime or a business as technology develops and costs decline.
Due to the gases and other pollutants they produce, 3D printers, unfortunately, may also significantly impact indoor air quality. We will look at the contaminants that printers emit and which equipment is best suited for removing those pollutants to determine the best air purifier for 3D printers to offset the effect of 3D printers.
Three-dimensional shapes are produced by 3D printers using several techniques. However, most commercially available 3D printers for consumers or smaller businesses use a method called molten polymer deposition (MPD) and also known as fused deposition modeling, this procedure (FDM). MPD printers melt plastic at temperatures as high as 320°C through a nozzle, deposit it in thin layers, and then build up those layers to create the desired object. Plastics start disintegrating when heated to high temperatures, releasing fumes and fine contaminants into the atmosphere. These air contaminants should be easier to reduce using an air purifier.
Release of Fumes and Particles from 3D Printing
Heat naturally causes certain fumes to be released into the air when plastic filaments are heated. “VOCs,” or volatile organic compounds, refers to a group of gases that make up these emissions. Many typical FDM filament materials start producing VOCs well below the temperatures required to make them malleable enough for printing, despite the misconception held by some that printing at lower temperatures can lessen the hazards connected with fumes.
The fact that FDM printing emits ultrafine particles, or UFPs, which are tiny airborne particles, is even more concerning. UFPs can enter the bloodstream through the lungs and spread throughout the body.
It has been demonstrated that exposure to UFP strongly correlates with heart disease and lung cancer.
Safe 3D printing techniques
Of course, 3D printing is an excellent hobby and a vital part of many manufacturing companies. Instead of stopping your printing activities, you should make a few changes to make it safer to address the issues caused by 3D printer emissions. Printing in an open area with sufficient ventilation is a straightforward modification you can make. As a result, there won’t be a chance for printing-related particles and odors to collect. You can also use PLA instead of ABS or nylon whenever possible because it emits fewer emissions, albeit it isn’t a perfect substitute.
Yet, if you’re serious about protecting yourself from dangerous airborne particles, you should consider purchasing an air purifier for 3D printing. The gases and particles that 3D printers emit can be contained with the correct air purifier. Choosing the proper air purifier for the job, nevertheless, is crucial.
Does the choice of filament and printer matter?
Naturally, not all filaments for 3D printers are the same. Filaments emit varying amounts of emissions, just as they do in terms of their material characteristics. As an illustration, the levels of VOCs and UFPs produced by ABS and PLA are substantially different. ABS releases UFPs at a pace roughly an order of magnitude higher than PLA. Although PLA filament is still regarded as having a high UFP emission rate, it is still not entirely risk-free. Another popular filament material, nylon, is considered to have a similar risk level to ABS.
Your chosen printer somewhat influences the number of fumes and UFPs you’ll be exposed to. Vents are frequently incorporated into industrial 3D printers. Regrettably, most affordable home 3D printers need vents. Furthermore, compared to professionals who regularly use 3D printers, hobbyists whom 3D print at home are frequently exposed to higher amounts of VOCs and UFPs.
