Systems and methods for generation of a truss

A system for manufacturing a truss of a three dimensional (3D) object representation, comprising:

• at least one hardware processor executing a code for:
• receiving a freeform b-rep model of the 3D object representation;
• arranging within an interior space of the freeform b-rep model of the 3D the 3D object representation, a plurality of instances of a sphere having a common radius to create a packed sphere arrangement;
• computing nodes of a truss that conform to the freeform b-rep model of the 3D object representation, each respective node positioned at a center of each respective instance of each sphere of the packed sphere arrangement;
• computing beams of the truss that conform to the freeform b-rep model by connecting adjacent nodes with respective beams,
• wherein the truss conforms to the freeform b-rep model;
• and manufacturing the truss that conforms to the freeform boundaries of the b-rep model.

A computer program product for manufacturing a truss of a three dimensional (3D) object representation, comprising:

• a non-transitory memory storing thereon code for execution by at least one hardware processor, the code including instructions for:
• receiving a freeform b-rep model of the 3D object representation;
• arranging within an interior space of the freeform b-rep model of the 3D object representation, a plurality of instances of a sphere having a common radius to create a packed sphere arrangement;
• computing nodes of a truss that conform to the freeform b-rep model of the 3D object representation, each respective node positioned at a center of each respective instance of each sphere of the packed sphere arrangement;
• computing beams of the truss that conform to the freeform b-rep model by connecting adjacent nodes with respective beams,
• wherein the truss conforms to the freeform b-rep model;
• and manufacturing the truss that conforms to the freeform boundaries of the b-rep model.
