Evenwith the abundance of 3D printers, MIT doesn’t collect PLA to degrade it. This means that all of the scrap PLA heads towards landfills, which lack the conditions to properly break it down. the fumes produced in 3D printing may pose distinctive health risks. 3D printing requires melting plastic and pushing it through a nozzle to form TheUFPs are, by definition, nanoparticles because their diameters are no larger than 10 nanometers. The wide size range for the UFPs is due to the different kinds of printing technology used. A 3 3Dprinting or additive manufacturing allows users to “print” a variety of items, from airplane parts to prosthetic limbs. 3D printing is still a relatively new technology and there are many gaps in the information available about health and safety implications. As with many innovations, workers are the first groups exposed to potential
Moreover another study investigated the effects of infill density on the compressive strength of 3D-printed pure PLA cylinders. They reported a failure load of 21 kN on cylinders with 80% infill [ 46 ], the same compressive failure load as that obtained for the pure PLA with 100% infill density in this study.
Iwould highly recommend against it as there aren't any long term studies on the health effects of those fumes, if you are going to be printing in a bedroom with anything other than pla, I would recommend opening a window, opening the door, and not being in the room for an extended period of time. Happy printing! 1. r/3Dprinting.
Thegrowing use of 3D printers in private and occupational spaces raises the question as to whether human exposure to emitted substances may cause adverse health effects. In a recent study, Gümperlein et al. (2018) exposed 26 healthy adults to particles and VOCs from 3D printing (PLA and ABS).

Myth#1: 3D printing PLA is 100% safe when there is no ventilation system in place. It has been proven that PLA produces more toxic particulate matter than ABS. then you are undoubtedly inhaling VOCs and ultrafine particles that may have health effects later on. Myth #3: 3D printers must be ventilated outdoors or they cannot be filtered.

Therefore we highly recommend using PLA with your 3D printers if your health concerns you. Before you get all fuzzy and mushy about PLA, we have to give you a word of warning. You need to select the right brand when you buy PLA. Some manufacturers add various additives to PLA to make it more colorful or to enhance other
Thispaper analyzed the effects of accelerated aging through UV-B exposure on the mechanical properties of 3D-printed parts made from PLA and PETG, two common MEX 3D-printing materials. Following mechanical testing, it was found that the mechanical strength decreased slightly for PLA samples undergoing a 24 h UV-B exposure and
