A common error for additive manufacturing processes is layer shifting. Layer shifting is an error that is usually caused by a hardware failure on the machine and shifts the position of layers in a 3D print over in the x or y-axis. An analysis was conducted to determine the additional stress concentrations that are introduced due to these defects. 3D models were generated in three phases of complexity and layer shifts were introduced at three points for each model. Layer shifts were limited to 0.1 inches for initial testing. The differences in layer shifts and layer shift orientation were examined in later-stage testing.
