Summary/Abstract: This paper discusses the need for noise modeling and simulation for better placement of noisy 3D printers in faculty laboratories where also teaching and research require audible levels of sound for human interactive speaking. The new development of 3D printers made them available and in current use for learning purposes in technical faculties from universities all around. While the noisy versions of 3D printers are operating in a lab where professors need to dialogue with the students it becomes compulsory to search for a placement that does not cumulate high levels of dB(A). As Sounds purposes, a Sound Level Meter device was used, and noise was recorded as a 0.5-meter grid map of the lab in various conditions of all 10 printers performing different tasks. Data was further processed and following sound propagation laws, considering wall reflection, a model of noise was developed and implemented as a MATLAB software simulation.
