This study explores the use of difluorenylsuccinonitrile-containing methacrylate (DFMA) as a mechanochromic cross-linker in polymer system (N,N-dimethyl acrylamide, DMAA) for resin-based three-dimensional (3D) printing applications. The effect DFMA content on mechanical properties and color response under stimulation was evaluated using tensile tests analysis. With increase content, particularly when it reached 1.0 mol %, strength intensity increase. incorporation also enabled detection localized chain scission. Rheological analysis demonstrated that DFMA–DMAA mixture exhibited favorable photocuring behavior, making suitable liquid crystal display 3D printing. Moreover, optimal conditions were determined to minimize dimension distortion printed specimens. A correlation between red–green–blue (RGB) values stress–strain behavior established based analysis, providing comprehensive understanding material. These findings highlight potential P(DFMA–DMAA) creating customizable, 3D-printed sensors with improved various
