1 ) A method for optimizing an additive manufacturing process, the method comprising: providing a first module of a computing device configured to: receive a data file defining a 3D conformation of a three dimensional object, said data file defines at least one specified property requirement of the three dimensional object; generate a set of print instructions, based on the data file and one or more slicing parameters; and providing a second module, of the computing device, in communication with the first module, the second module configured to: constitute a filament object model of the three dimensional object using the set of print instructions; analyze the filament object model and compute at least one property of the filament object model; compare the properties of the filament object model with the specified property requirements of the three dimensional object; and instruct the first module to modify one or more slicing parameters, thereby modifying the print instructions, when there is at least one mismatch between the computed properties of the filament object model and the specified property requirements for the three dimensional object.
