Claim 21:
22. A device for three-dimensional (3D) printing of structures in a vertical orientation, comprising:
a construction frame;
one or more material dispensers with flowable build material in said material dispensers; a construction area in a space defined by the construction frame, and
a separate continuous or semicontinuous rotating build platform,
the rotating build platform positioned horizontally within said construction frame and configured for building a solidified 3D structure on the rotating build platform and in the construction area, said rotating build platform moveable vertically within and configured to rotate within said construction frame while the flowable build material is delivered in a controlled manner to the rotating build platform or onto the 3D structure being formed thereon;
the material dispenser being positioned for controlled delivery of the flowable material onto the rotating build platform or in the construction area; and
one or more vertical-cavity surface-emitting laser (VCSEL) chips positioned to deliver radiation to selectively expose and solidify the flowable build material located on the rotating build platform or on the 3D structure being formed in a zone for curing while the rotating build platform is continuously or semicontinuously rotating;
said rotating build platform configured to receive and retain the build material delivered to said rotating build platform or into the construction area as the exposed flowable build material solidifies, the rotating build platform configured to move vertically and to rotate within the construction frame.
