Abstract Scope |
Converse to conventional additive manufacturing methods that apply layer-by-layer techniques, volumetric additive manufacturing produces the whole geometry simultaneously. While it is faster, creates features with better surface quality, and requires no overhang support structures, all of which push the limits of additive manufacturing, it is still premature and suffers from some effects such as component sedimentation. The sinking of the structure, in turn, adversely affects its geometric fidelity and resolution. The sedimentation rate of the printed body during its formation is highly dependent on the resin type, its viscosity, and its curing behavior. Herein, we propose a CFD model that takes into account the synergistic effect of reaction-based heating, curing behavior, and resin properties to predict the sedimentation rate of the printed geometry. The model results are in qualitatively good agreement with the experiments and can be used to quantify material behaviors that are beneficial when applying volumetric additive manufacturing. |
