3D printing using rotational components and improved light sources

A method of forming a three-dimensional object, comprising:

• providing a build platform being spaced apart from a construction area, the construction area having
• an optically transparent rigid member,
• a transparent substrate having a construction surface,
• and one or more material movers positioned to deliver and/or spread one or more flowable build materials in one or more channels formed in or on the transparent substrate, and
• a build region between said build platform and said construction surface;
• filling at least a portion of said build region with the one or more build materials;
• irradiating said build region through said optically transparent rigid member and at least a portion of the transparent substrate to solidify the one or more build materials while continuously or semicontinuously rotating said build platform and said transparent substrate having the construction surface to advance the one or more build materials across said optically transparent rigid member through an exposure zone while also continuously or semicontinuously advancing said build platform away from said construction surface to form said three-dimensional object from said solidified one or more build materials on said build platform,
• wherein said build platform and said construction surface together define a substantially perpendicular central axis, said build platform and said transparent substrate having the construction surface rotating about said central axis.

A method of forming a three-dimensional object, comprising:

• providing
• a build platform;
• a construction area having
• (i) one or more cure zones along an optically transparent rigid member;
• and
• (ii) a transparent substrate having a construction surface with at least one material channel formed therein;
• one or more material movers selected from the group consisting of at least one material dispenser and at least one material spreader for delivering at least one flowable, solidifiable build material about said at least one material channel;
• and
• a build region between said build platform and said construction surface;
• feeding said at least one flowable build material to at least a portion of said build region;
• irradiating said build region with one or more solidification mechanisms through the construction area and said transparent substrate to solidify the at least one flowable build material within an exposure zone;
• continuously or semicontinuously rotating said rigid member and said one or more material movers relative to said build platform and said transparent substrate having a build construction surface, while concurrently or semi-concurrently advancing said build platform away from said construction surface of the transparent substrate to form said three-dimensional object from said solidified build material on said build platform,
• wherein said build platform and said construction area together defining a substantially perpendicular central axis, and both of, said one or more material movers and said transparent rigid member rotating around or about said central axis.
