Abstract Scope |
Many methods of additive manufacturing rely on infill structures to decrease part mass and print time. However, standard infill patterns generally use a uniform density or require time-consuming analysis to generate a density field tailored to part geometry. We propose a Voronoi cell based infill structure which uses the medial surfaces of the object to locate thin regions and increase local material density. The Voronoi cell structure reduces stress-concentrating transition points within the infill, producing a more even gradient in density, while the weighting scheme ensures that traditionally weaker portions of the model receive adequate internal support. |
