Methods and system for enabling printing three-dimensional object models

A system configured to transform an inconsistent 3D (three-dimensional) model of one or more 3D objects into a valid printable 3D model, said system comprising:

• a) an input model file and/or modeler data provided from a data storage device;
• b) a sub-system configured to:
• b.1. receive an input model file and/or receive modeler data provided from said data storage device, giving rise to an input 3D model having one or more parts;
• b.2. analyze said input 3D model and remove its one or more inconsistencies;
• b.3. thicken the one or more parts of said 3D model, while preserving their functionality;
• and
• b.4. unify the union of the interior volumes of said one or more parts, thereby removing self-intersections and/or intersections between the two or more parts, thereby giving rise to a valid printable 3D model;
• and
• c) a 3D printer for printing said valid printable 3D model.

A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform a method of transforming an inconsistent 3D (three-dimensional) model of one or more 3D objects into a valid printable 3D model, said method comprising:

• a) receiving an input model file and/or receiving modeler data, giving rise to an input 3D model having one or more parts;
• b) analyzing said input 3D model and removing its one or more inconsistencies;
• c) thickening the one or more parts of said 3D model, while preserving their functionality;
• and
• d) unifying the union of interior volumes of said one or more parts, thereby removing self-intersections and/or intersections between the two or more parts, giving rise to a valid printable 3D model.
