A stereolithography apparatus comprises a fixed, vat () or a holder for receiving a removable vat for holding resin for use in a stereolithographic 3D printing process, a build platform (), a moving mechanism () configured to move said build platform in a working movement range be-tween a first extreme position proximal to said vat () and a second extreme position distant from said vat (), a working region between said vat () and said second extreme position of said build platform (), an optical imaging detector () having a field of view, installed and directed so that at least a part of said working region is within said field of view when said optical imaging detector is in an operating position and a controller () coupled to said optical imaging detector () for receiving optical image data from said optical imaging detector (). Said controller () is configured to use said optical image data in controlling operation of the stereolithography apparatus.

A dental CT apparatus includes a control system arranged to move a radiation source and an imaging sensor on the opposite sides of an imaging station. The control system includes at least a first imaging mode designed for imaging patients and means for selecting at least one second imaging mode in which the source of radiation and the imaging sensor are driven during an exposure at an angular velocity of less than 4 degrees/second. A digital three dimensional models of teeth are generated based on imaging impressions or models of teeth by a CT apparatus provided with at least one specific imaging mode for the purpose.
