Abstract:
A 3D printing system utilizes a circular-shaped build area revolving symmetrically around a single center point in a continuous helical printing process. A viscous, solidifyable liquid composition is deposited on a construction area where it is exposed to a solidifying medium to form a physical object that is attached to a build platform above and parallel to the construction zone. The build platform continuously rotates and simultaneously rises in a gradual programmed manner to continuously produce adhered layers of material deposited and bonded in a helical fashion. The construction area includes mechanisms to continuously remove therefrom excess build material not incorporated in the physical object formed.

Claim (Index 1):
An improved device for three-dimensional (3D) printing of structures in a vertical orientation, where the 3D printing device comprises:\n a construction frame, a material dispenser for delivering a flowable build material, said build material being solidifiable, a construction area and a separate build platform, both positioned horizontally within said construction frame and configured for inverted build of a solidified 3D structure there between, said build platform spaced from said construction area a defined distance and continuously moveable vertically within, and configured to rotate in a continuous or semi-continuous manner, within said construction frame so as to provide a continuously increasing or stepwise increasing defined distance between said build platform and said construction area in each 360\u00b0 rotation of said build platform, the material dispenser configured to deliver a film of the flowable build material onto an exposure zone of an upper surface of the construction area, and a solidification mechanism positioned to selectively deliver a solidifying medium to the flowable build material located on the exposure zone to convert selective portions of the flowable build material into a now-flowable film retained by the build platform said build platform configured to receive and retain said non-flowable film of build material deposited onto an upper surface of the exposure zone of the construction area as the film of flowable build material solidifies and the build platform is moved said defined distance vertically upward as the build platform rotates within the construction frame, wherein, the improved device comprising a mechanical system for removing excess flowable build material from the construction area.
