Investigation of Thermal Performance of 3D Printing Integrated Phase Change Materials in Building Structure

Abstract

This paper aims to create an experimental building structure using 3D printing technology to reduce the interior temperature. Because of its sensitivity to high temperatures, particularly its low heat deflection temperature, and susceptibility to deterioration over time, the Polylactic acid (PLA) material has been preferred to print the layer. In this model, an effort was made to decrease the building's overall cooling load, which may result in a higher amount of ordinary power being required. For the study, a new model of the intended wall was developed and tested. The studies were carried out in two modes: the first without any PCM in the wall, and the second with an additional new model of PCM 3D-printing layer within the wall. The test results demonstrated that the PCM 3D-printing layer inside the wall building lowered the temperature of the outer wall surface, the inner wall surface, and subsequently the building temperature of the indoor area to a huge amount. The achievements are in the percentage peak temperature reduction of 9.8% for the wall's outer surface, 22.6% of the inner wall surface, and 13.4% of the room temperature. With the help of the PCM 3D-printing layer, the peak indoor temperature was decreased by 5℃.

“…Jafari et al [17]claim that the recommended 3D-printed wick would improve heat transfer efficiency due to its capillary performance and excellent permeability. When Salih et al [18]used a PCM 3D printing layer to create a new model layer in walls, the temperature peak indoors was decreased by 4.5°C. The 3D printed lattice structure satisfies requirements for space applications in terms of heat transfer, weight, optical, mechanical, acoustic, and other factors.…”
