Development of 3D printer heating block using clad plate material

Abstract

In this study, the design analysis and the explosion welding were made into a clad sheet by the convergence method in order to solve the problem of heat transfer to the guide due to the heating of the 3D printer heating block. The shear strength of the clad plate material was tested and the results were analyzed by thermal analysis, thermal conductivity and thermal imaging. The following conclusions were obtained. 3D modeling of the heating block made of copper and titanium clad plate material The thermal analysis showed that the surface temperature of the filament guide area was lower than the heating block surface temperature. The average shear strength of copper and titanium clad plate material was measured and the average value of 195.6MPa was obtained. The thermal conductivity of the heating block made of copper and titanium clad plate material was measured three times and the average value was 62.52 W / m⋅K. The surface temperature of the heating block made of copper and titanium clad plate material was measured by a thermal imaging camera at a maximum of 107.3℃ and 183.2℃ at the filament guide. The temperature distribution was 89℃ lower than that of the existing filament.•
