This paper attempts to expand the data for the thermal properties of materials used in 3D printing, which was considered limited before. This new data set may be useful in accelerating new developments and designs of heat exchangers. The effect of layer height and width are accounted for in the presented measurements. It is shown from varying these dimensions that as the layer height and width increase the thermal conductivity ...
Thermal conductivity measurements were performed on polyamide 12 and polyamide 11 powders containing carbon nanotubes using the transient plane source (TPS) technique. The effects of powder density and temperature on thermal conductivity were investigated, as well as the effects of using previously heated powder. The thermal conductivity was found to increase with increasing density. For tests involving fresh powder, the thermal conductivity was found to increase linearly with temperature. For the previously ...
The Transient Plane Source Method is a helpful tool to test for the thermal conductivity of homogenous materials, however researchers at both the Chalmers University of Technology and Gothenberg University have created a process to test the thermal conductivities of inhomogeneous materials. For this experiment, a thermal analyzer was used to determine the thermal conductivities of four different sample materials (polymers and Pyrex glass) – each with different sizes and defects. ...
