Abstract

In this paper, the author proposes an exploratory study in which it is possible to observe the evolution of formaldehyde emission in a printing process in which mash stereo lithography (MSLA) is used. To conduct the experiment, individual sensors and a device are used to determine the two types of gas emission. These allow us to observe the evolution of emission in several points considered in relation to the integrated 3D printing system. From the experimental tests performed at the level of the space in which the printing process is performed, the change in formaldehyde and volatile organic compound is smaller during the printing process. It can also be seen that it is important to control and reduce the level of formaldehyde and then to control that which is generated for the volatile organic compound.
