EN During additive manufacturing, particulate matter and volatile organic compounds are released. These pollutants contribute to irritation of the throat mucosa, cause cardiovascular disease and even stroke. The article determines the quantitative and mass share of particulate matter emissions during 3D printing from black ABS filament. The tests were carried out using an analyzer from the PEMS group. The obtained dust emission results were presented for both the entire processes and their most important parts. It was shown at which stage of additive manufacturing the emission is the highest. The greatest emission of pollutants occurred during printing, when samples were taken directly from the machine chamber. The PM mass emission intensity during printing reaches its highest values in the raft printing process. This is due to the large surface area of the material heated by the printing table during this operation, and thus the longer plasticization time of the ABS material itself. At the same time, the highest quantitative particle emission values occur in said raft printing step and during the heating of the nozzle and in the first phase of correct printing. It follows that precisely in these two periods there is a significant emission of small diameter (mass) particles. In rooms where we have many printers at our disposal, which print products simultaneously, special care should be taken. These rooms should be ventilated frequently or air purifying filters installed.
