Thermal conduction in three-dimensional printed porous samples by high resolution infrared thermography
[EN] The thermal conductivity (κ) is a key parameter that defines many of the technological uses of three-dimensional (3D) porous architectures. Despite the variety of methods for determining κ, problems generally arise when re-searchers try to apply them to cellular materials and 3D structures. The...

| Sumario: | [EN] The thermal conductivity (κ) is a key parameter that defines many of the technological uses of three-dimensional (3D) porous architectures. Despite the variety of methods for determining κ, problems generally arise when re-searchers try to apply them to cellular materials and 3D structures. The present work proposes an affordable lab-madedevice for analysing anisotropic heat flow in 3D porous architectures via high resolution infrared ther-mography. The method is validated using dense materials of known thermal conductivity. Temperature gradients measured for porous specimens have been correlated to the thermal conductivity estimated from a simple resistors model, assessing the main factors that affect the experimental measurements. The porous specimens of SiC, MAX- phase and graphene-based nanostructures are in-house manufactured by direct ink writing (robocasting). |
