Abstract:
A method of minimising distortion in a workpiece is described that includes utilizing a computer system to carry out finite element analysis on a finite element thermo-mechanical model of the workpiece during and after fabrication by additive manufacturing to predict shape distortion and residual stress development in the workpiece, wherein the fabrication includes the fabrication step of depositing multiple layers of a material melted by a heat source along a deposit path on a substrate, and introducing alterations to the workpiece prior to or during fabrication to compensate for the predicted distortion.

Claim (Index 11):
An additive manufacturing apparatus, comprising:\n a feeder configured to introduce a feedstock onto a substrate; an electron beam gun configured to melt the feedstock on the substrate; a control device for controlling operation of the feeder and the electron beam gun; and a computer system comprising:\n a main memory for storing computer readable code for a finite element analysis application module; and \n at least one processor coupled to the main memory, said at least one processor executing the computer-readable code in the main memory to cause the application module to carry out finite element analysis on a finite element thermo-mechanical model of a workpiece during fabrication to predict shape distortion in the workpiece, residual stress development in the workpiece, or both.
