Effect of Temperature on the Emission Rate of Particulate Matter during 3D Printing and Characteristics of Initial Peak

Haejoon Jeon
Three dimensional (3D) printers based on fused deposition modeling (FDM) technology are rapidly becoming popular. Various harmful substances including gas and particulate matter are known to be released during 3D printing by heating thermoplastic materials at high temperature conditions. Previous study reported that the particle concentration increased as the temperature rising and occurred highest emission at early stages of printing although limited paper mentioned about the effect of temperature on the particle emission and the high concentration of the early printing. The aims of this study were to evaluate the effect of temperature on the emission rate of particulate matter during three-dimensional (3D) printing using different filament types and to investigate the mechanism of the highest concentration peak in early stage of printing.
