The paper addresses a topic that intersects the need for innovation through the development of new manufacturing processes with the need to ensure minimal interaction with the environment, as well as low risks regarding operation with polymer processing processes. It is therefore studied the 3D printing process, a process in full development for both prototyping and production activities, the study looking at its polluting emissions. Sound pressure measurements were performed to assess the noise level. The recorded values were around 44 dB, thus highlighting a minimal risk for the user. Another pollutant factor assessed was the fume emitted during the process. Determinations of the intensity of fume emission and evaluations of the concentration of carbon monoxide and carbon dioxide in the composition of the fume were carried out. The measured values of the emission intensity were located around 0.13 mg/s, which is much lower than those specific to welding processes. The concentrations of carbon dioxide and carbon monoxide had values in the range of 410-520 ppm, being significantly lower than the values considered dangerous for users' health. The overall conclusion was that FFF 3D printing is a relatively safe process for operators and has minimal interaction with the environment due to low pollutant emissions.
