3D printer visualization shader and geometry procedural

An electronic device for rendering a pre-visualization image representative of a 3D object to be printed by a 3D printer, the electronic device comprising:

• one or more processors;
• and
• memory storing one or more programs configured to be executed by the one or more processors, the one or more programs including instructions for:
• accessing a geometric digital model of the 3D object;
• receiving one or more printer characteristics of the 3D printer, wherein the one or more printer characteristics are associated with settlement of added material to the 3D object by the 3D printer;
• receiving one or more material parameters of a volume of the added material that forms the 3D object;
• generating a digital aggregate build-up model of the 3D object using the geometric digital model, the one or more printer characteristics, and the one or more material parameters, wherein generating the digital aggregate build-up model includes:
• determining a voxelated surface of the build-up model;
• and
• either or both:
• adding one or more bevel edges to the voxelated surface along a concave external surface edge between two or more orthogonally adjacent surfaces of two or more voxels, and
• beveling one or more edges to the voxelated surface along a convex edge of two or more orthogonally adjacent surfaces of a voxel;
• and
• rendering a pre-visualization image representative of the 3D object as the 3D object would be printed by the 3D printer based on the generated digital aggregate build-up model.
