Abstract
A 3D printing apparatus and method corrects for skew in the motion components of the apparatus without the use of an independent reference object. A calibration object having features therein or thereon is printed. A user rotates the calibration object by a certain angle after it is printed. The features in/on the calibration object are measured, and an amount of skew is determined based on the measurements. In addition, a 3D printing operation is compensated based on the effects of a coefficient of thermal expansion and/or moisture absorption on dimensional changes.
