Suspension system for adjusting projected light images

A suspension system comprising:

• a. a mounting apparatus positioned in proximity to a projection system, or containing a projection system, wherein the projection system comprises one or more of a Digital Micro-Mirror Device, a Liquid Crystal Display Screen, and/or a Laser galvanometer;
• b. an optic or optics comprising one or more lenses;
• and
• c. an attachment mechanism linking the optic or optics and the mounting apparatus, wherein the attachment mechanism comprises one or more of a screw, a hollow or telescoping screw with or without a spring or springs, a piston or hollow piston, a linear actuating device, a computer-numerically-controlled (CNC) actuator, and/or a stepper motor;
• d. wherein the system is capable of being used in association with three-dimensional printing or additive manufacturing;
• and
• e. wherein an orientation between the optic or optics and a projected plane is capable of being adjusted to one or more of the following positions:
• (i) 0 degrees along a z axis, and allowing for increasing or decreasing a distance between the optic or optics and a projected image and the Digital Micro-Mirror Device, thereby being capable of changing the focal plane and pixel sizes to limits of ultraviolet light;
• (ii) Spatially along an x-y plane in relation to a projected image, including centering the optic or optics over the projected image;
• and/or
• (iii) A 45 degrees or less tilt to a z axis in an x-y plane, allowing a tilt in any direction to cause, reduce, eliminate, or enhance a keystone effect(s).

• d. wherein the system is capable of being used in association with three-dimensional printing or additive manufacturing;
• e. wherein the optic or optics are suspended from a solid body, and wherein the optic or optics are connected to the solid body by adjustable fasteners, which are capable of allowing an adjustment of a distance between the optic or optics and the solid body;
• f. wherein the optic or optics is capable of being moved closer to or farther from the solid body either continuously or by incremental steps;
• g. wherein the optic or optics are capable of being moved closer to or farther from the solid body by an adjustable screw, a piston distance, a stepper-motor, or combinations thereof, before or during the three-dimensional printing or additive manufacturing;
• and
• f. wherein the pixel pitch formed ranges between about 0.1 um and about 2 mm.
