3D printing
3d printers do produce noise as its operation involves a lot of vibration. The University of Michigan shown how much sound does a 3d printer may produce. Their research shows that sounds more than 85 DB is harmful for human. However, the good 3d printers with silent motherboard may limit the noise up to 55 DB. Still there are plenty of manufacturers who could not even identify the best way of reducing 3D printer's noise. But, there are some techniques that can help you to identify the quiet 3d printers and prepare yourself to reduce the noise at a substantial level.
