1. A device for three-dimensional (3D) printing of structures in a vertical orientation, comprising:
a continuous or semicontinuous rotating build platform moveable vertically and configured to rotate around a central axis;
a material dispenser with a flowable build material in said material dispenser, said material dispenser being positioned for controlled delivery of the flowable build material to an exposure zone on a surface of the build platform or a 3D structure being formed on the build platform; and
one or more laser diode chips on or adjacent said material dispenser, said laser diode chips positioned to deliver radiation to solidify the flowable build material delivered in a controlled manner to the rotating build platform or the 3D structure being formed thereon while the rotating build platform is continuously or semicontinuously rotating and when said build material is located in or on the exposure zone.
