3D printing is harmful allthingsblogging.com
3D printing has an adverse effect on the health of people who operate printers, scientists from Georgia Institute of Technology. In principle, there is no surprise. Inhalation of the heated plastic to anyone and under no circumstances does not work for good. It has been known for several years that desktop 3D printers operating without a shield can be potentially dangerous due to the formation of the finest particles (UFPs) and volatile organic compounds (VOCs). Now, however, there is hard evidence. Researchers conducted a series of tests to investigate the effect of these compounds on human respiratory cell and rat immune system cultures.
"All tests were performed using high concentrations. Their results pointed to the toxic effects of various filaments used in the 3D printing process, "says Dr. Rodney Weber, supervisor of the tests Gatech.
During the operation of the 3D printer, the plastic is melted and then applied in layers. Heating of the filament releases volatile compounds. Naturally, the higher the melting point, the stronger the emission of these compounds. One of the most popular materials for 3D printing, ABS (acrylonitrile-butadiene-styrene terpolymer), caused more emission than polylactide (PLA), which melts at lower temperatures. However, PLA is more toxic, although both compounds have a negative effect on cell viability. However, ABS emissions are much stronger, so these particles are a bigger problem for the health of the printer operator.
"Our tests indicate that long-term exposure to particles released during the melting of filaments can have a similar effect on health as exposure to air pollution in cities caused by, among others exhaust gases "- commented on the results of tests Dr. Weber.
The conclusion of the study is simple. If you are using a 3D printer, it is worth placing it in a room with efficient ventilation and rather not leaning over it without necessity, even if you are printing something amazingly wonderful. You don't necessarily need a gas mask. However, common sense comes in handy.
