The method of printing can include dispensing a first interface material for the construction of the three-dimensional object, dispensing a second interface material to form a support structure for supporting the three-dimensional object and dispensing a third interface material which May be Used to separate the support structure from the 3-D object Disclosed also a method for producing a 3-D model containing various kinds of inserts.
Abstract:
A method for manufacturing ear devices that are individualized for individual. Data of the three-dimensional shape of each individual's area of application for a haring device is provided. Individual shells for the hearing devices are construed by respectively depositing commonly a layer of one of a fluid and a powderous material and solidifying by a laser arrangement in the layer individually shaped layers of the individual shells, thereby controlling the laser arrangement with the data.
Abstract:
A method for forming a non-rubbing alignment film is provided. A polymer film is formed on a substrate. A plurality of microgroove structure is then formed on the surface of the polymer film by the molecular imprint method to prevent electrostatic damage and micro particle contamination produced by the conventional rubbing method.
Abstract:
A system and method for forming a polymeric molding. A mold component includes a transmissive portion for passing curing energy such as UV light into the mold cavity. A masking collar is engaged around the transmissive portion to block curing energy from exposing and curing polymeric material outside of the region underlying the transmissive portion.
Abstract:
Described are methods for patterning a substrate by imprint lithography. Imprint lithography is a process in which a liquid is dispensed onto a substrate. A template is brought into contact with the liquid and the liquid is cured. The cured liquid includes an imprint of any patterns formed in the template. In one embodiment, the imprint process is designed to imprint only a portion of the substrate. The remainder of the substrate is imprinted by moving the template to a different portion of the template and repeating the imprint lithography process.
Abstract:
The present invention provides curable compositions and rapid prototyping processes using the same. In one embodiment, the present compositions include one or more aromatic epoxies and one or more aliphatic epoxies, and, after full cure, exhibit a heat deflection temperature of at least 105null C. and an elongation at break of at least 1.5%.
Abstract:
A device and a method for the layer-by-layer generative manufacturing of three-dimensional objects by selective hardening of a previously applied layer by means of laser radiation, wherein a laser (1) contains a switching device (8) for changing the modal composition of the laser radiation. By changing the modal composition of the radiation during the selective hardening of a layer, the focussing features (nullfocusabilitynull) of the radiation is increased in areas (25), in which high structural accuracy is required. In the remaining areas to be illuminated, the required illumination time is reduced by increasing the intensity of the radiation.
Abstract:
This invention relates to semiconductor devices, microelectronic devices, micro electro mechanical devices, microfluidic devices, photonic devices, and more particularly to a lithographic template, a method of forming the lithographic template and a method for forming devices with the lithographic template. The lithographic template (10) is formed having a substrate (12), a transparent conductive layer (16) formed on a surface (14) of the substrate (12) by low pressure sputtering to a thickness that allows for preferably 90% transmission of ultraviolet light therethrough, and a patterning layer (20) formed on a surface (18) of the transparent conductive layer (16). The template (10) is used in the fabrication of a semiconductor device (30) for affecting a pattern in device (30) by positioning the template (10) in close proximity to semiconductor device (30) having a radiation sensitive material formed thereon and applying a pressure to cause the radiation sensitive material to flow into the relief image present on the template. Radiation is then applied through the template so as to cure portions of the radiation sensitive material and define the pattern in the radiation sensitive material. The template (10) is then removed to complete fabrication of semiconductor device (30).
Abstract:
A selective inhibition of sintering (SIS) technique may be used to fabricate a three-dimensional (3-D) dense metal object from a binderless metal powder. A number of layers of metal powder are provided on a build tank. For each layer, regions of the layer are sinter-inhibited, e.g., by depositing a sinter-inhibiting material such as a ceramic slurry, a metal salt, or oxidizing metal particles in the powder using chemicals or a concentrated heat source. Each layer may be compacted before the next layer is provided. A final compact may then be sintered. Unwanted sintered sections may be removed from the compact at boundaries formed by the sinter-inhibited (unsintered) regions, and the object extracted.
