    Macroporous scaffolding for bone tissue engineering, three-dimensional design method and applications. Method of obtaining, by computer-aided design computational techniques based on the voronoi method, an interconnected and variable macroporosity scaffold defined from the trabecular thickness of non-constant section (tb.th), the trabecular separation (tb.sp ), the number of voronoi nucleation points and the volume of the area to be filled of the bone defect for its manufacture by three-dimensional (3d) printing with biocompatible materials. This invention is applicable in the field dedicated to the manufacture of biocompatible, biodegradable and bioactive scaffolds for the regeneration of bone tissue with rapid prototyping techniques in applications that require the variable combination of porosity, resistance and permeability in different regions thereof for the purpose of to improve the combination of resistance and the flow properties or mass transport.
