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 some embodiments, vertical-cavity surface-emitting lasers (VCSELs) are utilized as an energy source for curing the print material. The VCSELs can be integrated with the print head and can form an array which can be staggered or linear. In some embodiments, the VCSELs (and the corresponding print head)can be connected to a rotating platform, which can rotate independently from the revolving build area. In some embodiments, a thermoelectric cooler and/or a fluid cooler can provide cooling to the VCSELS.

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.

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.
