Abstract:
1. An apparatus for forming a three-dimensional object from a solidifiable material, comprising: a solidification energy source; a linear scanning device in optical communication with the solidification energy source; and a solidification energy sensor in optical communication with the linear scanning device; wherein the linear scanning device is spaced apart from the solidification energy source and the solidification energy sensor by a fixed distance and scans solidification energy received from the solidification energy source in a plurality of linear patterns along a source of the solidifiable material while the linear scanning device moves in a first direction, each linear pattern has a length along a second direction, and the solidification energy sensor receives solidification energy from the solidification energy source each time the linear scanning device scans a linear pattern of solidification energy along the source of the solidifiable material.
