Apparatus and method to predetermine a mechanical property of a three-dimensional object built by additive manufacturing

A computer implemented apparatus and method for receiving tool paths that a dispensing head follows to deposit roads of material for successively building object layers of a 3D object during an additive manufacturing process, generating simulated object layers of a simulated 3D object from the tool...

Zusammenfassung:	A computer implemented apparatus and method for receiving tool paths that a dispensing head follows to deposit roads of material for successively building object layers of a 3D object during an additive manufacturing process, generating simulated object layers of a simulated 3D object from the tool paths, wherein the simulated object layers represent an interior geometry of each one of the object layers, determining a contact surface area between adjacent ones of the simulated object layers, and determining a predicted mechanical property of the 3D object from the contact surface area and a material property of the material.
