Investigation into the Influence of Fused Deposition Modeling (FDM) Process Parameters on the Thermal Properties of 3D-Printed Parts
MetadataShow full item record
The mechanical properties of 3D-printed parts have been extensively studied and the effects of printing parameters on them have been investigated. However, there are limited reliable data for the thermal properties of the materials used for printing, which can impede the development of additively manufactured heat exchangers made from either pure polymers or composites. In the current study, the effect of the layer height and width have been investigated experimentally and numerically to explore the thermal anisotropic nature of unidirectional printed parts printed using fused deposition modelling (FDM). The results show that increasing the layer height and width causes deterioration in the thermal conductivity, which may reach 65% of reduction compared to the pure polymer.
