Characterisation of moisture sorption of materials used in 3D printing

Investigation of environmental effects on properties of polymers and 3D printed structures was performed. The research methodology of moisture sorption and swelling processes was developed and implemented. Full-scale experiments were performed on 12 materials. Degradation of filaments’ mechanical properties under moisture effect was evaluated. A complex analysis of the results was performed, and sorption characteristics of filaments were defined.

This research was supported by ERDF Project No. 1.1.1.1/19/A/031 "OPTITOOL, Decision Tool for Optimal Design of Smart Polymer Nanocomposite Structures Produced by 3D Printing".
