Thermal conduction in three-dimensional printed porous samples by high resolution infrared thermography

open access: yesOpen Ceramics, 2020
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 researchers try to apply them to ...
