Patent attributes
Methods, devices and systems for efficient 3D printing using 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. Laser diodes or 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.
