| 20100224605 | RAPID PROTOTYPING DEVICE AND METHOD WITH INDIRECT LASER EXPOSURE - It is desirable for the production of workpieces, which are sometimes produced by a rapid prototyping method, to be further automatable. To this end a device is provided having a laser for generating a laser beam in order to set a material, and a workpiece support which can be exposed directly to the laser. There is also provided an optical instrument for redirecting and deviating the laser beam so that the workpiece support can also be exposed indirectly to the laser. Material can therefore also be cured more easily in undercuts of workpiece blanks. | 09-09-2010 |

| 20100019417 | DEVICE AND METHOD FOR CURING HEARING AID HOUSINGS - A device and a method for curing plastic moldings are particularly suited for curing hearing aid housings. A light source emits curing light and a holder, at least partially transparent to curing light, holds the plastic moldings. The holder has an elongate light guiding element, which is transparent to curing light, which has an emission portion for emitting curing light in a number of spatial directions, and which is formed in such a way that at least the emission portion can protrude into a convex curvature or an interior space of a plastic molding that is being held by the holder. The light guiding element guides curing light emitted from the light source to the emission portion and emits from there. The light guiding element may have a holding portion for holding the plastic molding. The holding portion and the emission portion may spatially overlap. The method includes a step of irradiating the plastic molding with curing light simultaneously on the outside and the inside by the light source and by the light guiding element. Particularly uniform curing without localized temperature peaks is achieved. | 01-28-2010 |
