- <p><span lang="EN-US">This study investigated the mechanical behavior of 3D-printed stochastic lattice structures using a semi-controlled design. This study aims to predict and optimize the mechanical response under compressive stress acting on the lattice structures of Acrylic Styrene Acrylonitrile (ASA) filament<span lang="EN-US">s</span>. Shifting from stochastic to semi-controlled tesselation using Rhinoceros 7 software enables the effective creation of proposed design models and thus achieves predictable and reliable mechanical responses. <span lang="EN-US">The </span>design parameters, including nodal formation, strut thickness, and lattice generation based on a predefined geometric routine, are associated with <span lang="EN-US">the </span>regulation <span lang="EN-US">of the relative density. This approach aims to minimize the effect of relative density on </span>the actual stiffness and strength evaluation. The findings focused on compressing the structures’ designs generated via <span lang="EN-US">a parabolically</span> distributed Voronoi population to failure and observing their mechanical response through the stress-strain fluctuation analysis. Three distinct behavior stages are observed: elastic range, plastic range, and collapse without densification. The influence of crosslink geometry on <span lang="EN-US">the elastic responses was highlighted, with parabolic configurations affecting the peak stresses</span> and elastic line slopes. The structures exhibited pure<span lang="EN-US">ly </span>brittle behavior, characterized by abrupt local cracking and oscillatory plateau formation in the plastic stage. </span></p>
