Optimization of post curing in mask stereolithography

Additive production (also called 3D printing) allows the production of products of complicated geometry in a short production time. Even after 35 years of development since the initial prototyping, to this day some procedures are still exclusively for prototyping. MSLA is a low-budget process that uses liquid for production in which there are many processing parameters that could affect the improvement of mechanical properties and thus allow the application of the process for making functional products. The processes have many advantages, but one of the biggest disadvantages is the need for post curing after processing. In this paper, the effect of post curing time on tensile properties was determinated. After that, the optimization of the post curing process was performed, which shows that the desirability function within the range of post curing time is only 0.566, which does not fully meet the set criteria of maximum values of tensile properties, especially tensile strain.
