A new approach to making a photopolymeric composition was first elaborated in this work based on the use of poly‐ N , N ′‐( m ‐phenylene)isophtalamide as the heterochain polymer matrix together with 4 , 4′ ‐diphenyl oxide diacrylamide as the crosslinking agent. Reproducible three‐dimensional (3D) objects have been formed using a laser stereolithograph completed with a laser with wavelength of 405 nm. According to the thermogravimetric analysis, the thermal stability of the formed objects could be changed through a control from 260 to 405 °C. Moreover, it was proven that the tensile strength of samples of the crosslinked films reached 90.1 ± 3.2 MPa at the elongation at break of 12.4 ± 2.3%, depending on the forming parameters of such samples. © 2018 Wiley Periodicals, Inc.
