摘要： A replica 3D structure is fabricated inside a multi-layered mold by patterning each mold layer to define a void/opening that matches a corresponding cross section of the structure's peripheral surface, and filling the patterned opening of each layer with a structural material (i.e., before depositing a subsequent layer of mold material). The mold material (e.g., photoresist or another dissolvable sacrificial material) is blanket deposited (e.g., by slot-die, spray coating) and then patterned using a laser or a printed mask. Each layer of modeling material (e.g., polymer, ceramic or metal, or a combination thereof) is electro-plated or otherwise deposited on the previously formed modeling material layer. High vertical resolution is achieved by utilizing relatively thin mold layers. The mold layer deposition, patterning and modeling material deposition is repeated until the replica 3D structure is entirely formed inside the multi-layered mold, and then the mold is dissolved or otherwise removed.

摘要： A laser line generator system that utilizes a light guide element to convert high energy coherent light generated by a high fill-factor laser diode bar into homogenous light, and utilizes one or more slow-axis relay lenses to image the homogenous light such that it forms a homogenous line illumination pattern on an illumination plane. The light guide utilizes parallel or down-tapered side walls to mix received coherent light in the slow-axis direction by way of total internal reflection. A Keplerian telescope including two cylinder lenses is optionally used in place of the slow-axis relay lens. Optional fast-axis lenses are used to assist in focusing the homogenous light at the illumination plane. The laser light generator forms, e.g., a single-pass imaging system for a scanning/printing apparatus in which the homogenous line illumination pattern is directed onto a linearly arranged series of spatial light modulators, such as Digital Micromirror Devices (DMDs).
