3D printing using spiral buildup
First Claim
1. A device for three-dimensional (3D) printing of structures in a vertical orientation, comprising:
- a construction frame, a material dispenser with a flowable build material in said material dispenser, 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°
rotation of said build platform, the material dispenser being positioned 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 deliver a solidifying medium to the flowable build material located on the exposure zone, said build platform configured to receive and retain the film of flowable build material delivered on to the upper surface of the construction area as the film of flowable build material solidifies and is moved said defined distance vertically upward as the build platform rotates within the construction frame;
wherein the device further comprising a drainage system.

Abstract
Methods, devices and systems for efficient 3D printing that address conventional inefficiencies while utilizing a single compact device are set forth. Some embodiments utilize a circular-shaped build area revolving symmetrically around a single center point utilizing a continuous helical printing process. In one embodiment a liquid photopolymer for solidification is deposited on a build platform to form the physical object The Build platform is continuously rotated and simultaneously raised in a gradual programmed manner. Focused from below the platform produces a single continuous “layer” of material deposited and bonded in a helical fashion.

19. A three-dimensional (3D) printing device, comprising:
- a material dispenser for delivery of a film of a solidifyable liquid material;
a material solidification mechanism for causing the film of liquid to solidify, a build platform; and
a construction area having an exposure zone on an upper surface thereof, said build platform and said construction area configured for delivery of the film of solidifiable material to a space between the exposure zone and a lower surface of the build platform, said construction area and said build platform being positioned in substantially parallel planes, wherein said build platform is configured to rotate multiple 360°
turns in relationship to the construction area and continuously or semi-continuously increase, in each 360°
rotation, a defined distance between the build platform and the construction area such that rotation of said build platform causes portions of said film of solidifyable material delivered to said space and solidified into a structure to be retained on the lower surface of the build platform;
wherein the device further comprising a drainage system. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
