Systems and methods for fabricating three-dimensional objects

摘要

Systems and methods for fabricating three-dimensional objects. The system includes an optical imaging system providing a light source; a photosensitive medium adapted to change states upon exposure to a portion of the light source from the optical imaging system; a control system for controlling movement of the optical imaging system, wherein the optical imaging system moves continuously above the photosensitive medium. The method includes moving a maskless optical imaging system providing the light beam in a continuous sequence; presenting the light beam on a portion of the photosensitive medium; lowering a plate upon which the photosensitive medium resides; and applying a new layer of the photosensitive medium.

1. A system for fabricating a three-dimensional object, the system comprising:
a photosensitive medium adapted to change states upon exposure to a light source; an optical imaging system, configured to continuously move above the photosensitive medium, and having the light source and a spatial light modulator; a control system for controlling movement of the optical imaging system; and an XY motion stage with sub-micron position resolution, configured to move the optical imaging system.
