Thermal Insulation Capacity of a 3D Printed Material

摘要

The 3D printing process allows obtaining parts with different interior structures and made of different materials.Such parts can be used to avoid overheating of various objects under the action of thermal radiation.The existence of different internal structures of the parts,as well as the 3D printing conditions and the distinct physical properties of the materials used,determine a different behavior of the parts in terms of their thermal insulation capacity.To obtain an image of the thermal conductivity of thin parallelepiped-shaped parts achieved by 3D printing,experimental research is conceived and materialized.The experiments involve the use of an infrared heat source,respectively,measurement of temperature on the surface opposite to that exposed to thermal radiation.The obtained results are mathematically processed to obtain empirical mathematical models that would highlight 3D printed parts' ability to be used as thermal insulating materials.
