摘要： The present invention relates to a method for forming a 3D optical component comprising the steps of: forming over a substrate a liquid layer of a polymer in a solvent, drying said polymer for removing at least a portion of said solvent and thereby creating a layer having a first dissolution rate, exposing by multi-photon absorption using an electromagnetic radiation source a predefined volume of said layer, thereby causing the volume to have a second dissolution rate which is different to said first dissolution rate, dissolve the non-exposed areas with a liquid solution for forming the 3D optical component, wherein said polymer is Hydrogen silsesquioxane, HSQ, and said dried layer having a thickness of at least 1 μm.

摘要： Glass articles including one or more 3D printed surface features attached to a surface of a substrate at a contact interface between the 3D printed surface feature and the surface. The 3D printed surface feature(s) include a glass or a glass-ceramic, a compressive stress region at an exterior perimeter surface of the 3D printed surface feature(s), and a central tension region interior of the compressive stress region. The 3D printed surface feature(s) may be formed of a contiguous preformed material 3D printed on a surface of a substrate. The compressive stress region of a 3D printed surface feature may be formed using an ion-exchange process.

摘要： A laser-assisted microfluidics manufacturing process has been developed for the fabrication of additively manufactured structures. Roll-to-roll manufacturing is enhanced by the use of a laser-assisted electrospray printhead positioned above the flexible substrate. The laser electrospray printhead sprays microdroplets containing nanoparticles onto the substrate to form both thin-film and structural layers. As the substrate moves, the nanoparticles are sintered using a laser beam directed by the laser electrospray printhead onto the substrate.

摘要： A sensor may be to detect a height profile of build material for generating the three-dimensional object. A defect of the build material may be determined to exist based on the height profile of the build material. The defect may be corrected or the defect may be prevented from impacting a component of the system. A portion of a layer of the build material delivered by a build material distributor may be selectively solidified.

摘要： A method of forming an optical component includes fusing glass powder material to a facesheet to form a first core material layer on the facesheet. The method also includes successively fusing glass powder material in a plurality of additional core material layers to build a core material structure on the facesheet. The method can include positioning the facesheet on a mandrel prior to fusing glass powder material to the facesheet. Fusing glass powder material to the facesheet can include fusing the glass powder material to a polishable surface of the facesheet.

摘要： The invention refers to a process for rapid manufacturing that uses a focused ultrasound beam according to the invention. The process is based on the local ultrasound welding of the material (2) grains that is under a powder form, welding that takes place solely in the focal spot of the focused ultrasound beam, the focal spot being scanned across the X-Y-Z directions within the powder (2) bed so as to 3D build the entire object (7) that is desired. The processes taking place in the focal spot region are local melting, local melting due to friction followed by filling of the gaps existing between grains, removal of the grain asperities, local inter-diffusion between neighboring grains as well as other phenomena that take place at the interfaces between materials when these are subjected to an ultrasound field.

摘要： Methods for producing glass articles of a wide range of geometrical shapes, including shapes that are heretofore difficult or impossible to make monolithically. The glass articles are made by first building the nascent glass article from glass powder and a binder using a three-dimensional printing free-form fabrication process followed by sintering the nascent glass article at a temperature that is hundreds of degrees above the glass powder composition's glass transition temperature while supporting the nascent glass article in a bed of an inert powder having a high flowability.

摘要： A method of producing a quartz glass crucible by arc melting a quartz powder molded product loaded on the inner side of a mold while performing vacuum suction, includes initiating the melting of quartz powder from the rim edge of a quartz powder molded product, subsequently lowering the arc electrode or raising the mold to heat and melt the sections on the downside of the rim edge. The method is preferably carried out such that the inner surface of the crucible is sealed within a time corresponding to 10% of the total arc time starting from the initiation of arc melting, and the seal thickness is 3 mm or less. The quartz glass crucible thus produced is useful for the pulling up of silicon single crystals and has a uniform glass layer with fewer internal bubbles.
