  • Patent number: 10099421
    Abstract: 3-D printing transfers build material and support from an intermediate transfer belt (ITB) to a platen. The build material is the same as the support material, except that the build material includes a photoinitiator and the support material does not. The platen moves to make contact with the ITB, and the ITB transfers successive layers of build material and support material each time the platen contacts the ITB. The platen and a portion of the ITB that is adjacent the platen are heated prior to the platen contacting the ITB, and the same is exposed so as to crosslink polymers of build material, without crosslinking polymers of support material. The polymers of build material being crosslinked and the polymers of support material not being crosslinked makes the support material selectively soluble in a solvent.

    Abstract: A method of measuring the perimeter of a swimming pool has been developed. First, a laser measurement device with a rotary motor is placed on a tripod. Next, the device and tripod are located and leveled the laser measurement in an empty swimming pool and the scan sequence is initiated. The laser measurement device is calibrated and then begins collecting a data measurement of the distance from the side of the swimming pool to the laser measurement device. The laser measurement device is rotated laterally at a defined angle to a new position using the rotary motor and the process of collecting a new data measurement is repeated until the laser measurement device has rotated 360°.

    Abstract: Provided is a three-dimensional modeling apparatus including a stage, a constraining body, a supply nozzle, an irradiation unit, and a movement mechanism. The constraining body includes a surface including a linear region along a first direction, and is opposed to the stage so that the linear region is the closest to the stage. The supply nozzle supplies a material curable by energy of an energy ray into a slit region between the stage and the linear region. The irradiation unit irradiates the supplied material with the energy ray through the constraining body. The movement mechanism moves the stage relative to the constraining body along a second direction for forming a cured layer of the material for one layer, and moves the constraining body and the stage relative to each other along a stacking direction for stacking the cured layers.

In addition, while the polymer is being heated to form SiC, a second result, such as annealing of the underlying workpiece, or firing of the metal contacts is achieved. For example, the workpiece may be implanted prior to coating it with the polymer. When the workpiece is heated, SiC is formed and the workpiece is annealed. In another embodiment, a workpiece is coating with the SiC forming polymer and metal pattern is applied to the polymer.

  • Patent number: 8852694
    Abstract: A method of forming a polymer film includes dispensing a substrate and coating the substrate with a composition that is curable using actinic radiation. In an example, the method further includes exposing the composition to actinic radiation in presence of an atmosphere including 1 vol % to 37 vol % oxygen, whereby the surface of the composition forms an undulating morphology. In another example, the method further includes applying an oxygen-containing overlay over the composition, exposing the composition to actinic radiation through the oxygen-containing overlay, and removing the oxygen-containing overlay, whereby the surface of the composition forms an undulating morphology.

  • Patent number: 8846778
    Abstract: Ultraviolet light-curable deposits are printed onto a substrate in a predetermined pattern to make tactile marks (e.g. Braille-like resin dots) for use by people with impaired vision to, for example, recognize the denominations of banknotes. The deposit demonstrates high adhesion due to: (1) presence of 20-80% (wt.) of a low viscosity acrylate component to provide a substrate-penetrating property; and, (2) 2-30% (wt.) of an adhesion-promoting acid acrylate. The deposit material further includes 1-30% (wt.) of urethane acrylate, 1-30% by weight of reactive diluent, photoinitiator and 1-10% (wt.) of rheological adsorbing additive. Optimally, the adhesion promoter is added after the other components have been mixed with the rheological additive. The printing step may be followed by heating before the curing step to increase penetration of the ink into the substrate. The deposit may comprise a taggant for use as a security feature.
