Abstract

This paper outlines an innovative method for a modification of precise and versatile 3D printing technology to satisfy the need for easy and non-destructible spatial stress analysis on printed mechanical parts. A 3D printed photopolymer sample with SrAl2O4:Eu,Dy particle addition is tested and a following method of data processing for spatial stress mapping is offered. The empirical stress distribution maps is proven to be in accordance with the calculated stress distribution and can therefore be further developed for technological applications offering a good addition for computational stress–strain analysis. It opens the possibility for real time evaluation of complex uneven forces on complex parts therefore having a good potential for commercialization.
