Abstract

Due to the nature of FDM 3D printed polymer parts, they easily absorb water. Thermography can help characterize the level of water absorption based off a few different parameters, but the material state is highly dynamic and dependent on surrounding environment. The challenge for experimental test specimens is that water can continue to absorb into different portions of the part and dry in others. This makes it difficult to effectively identify and determine parameters for characterizing water degradation. This paper reports the initial evaluations of a procedure for thermography inspections that involves freezing 3D printed FDM parts as a means to stabilizing an absorption state. Placing specimens in a freezer has shown potential to stabilize an absorption state without significantly altering data.
