Abstract: A mosaic-style art kit is provided. The art kit includes a frame, modeling material, and a guide sheet. The frame includes a peripheral surface operably configured to overlie the guide sheet, and a mosaic-style internal structure having partitions forming cavities for receiving and retaining the modeling material. A front side of the frame is placed on the guide sheet such that the mosaic-style internal structure is aligned with a design on the guide sheet. The design thereby instructs a color of modeling material to be inserted into each cavity of the internal structure. The modeling material is inserted accordingly, and the frame and guide sheet are separated to produce a mosaic-style art product.

Abstract: The invention relates to a process or a device for the production of a three-dimensional object by layer-wise solidification of a photo-polymerizable resin by means of a planar or essentially planar construction/reference plane, at which the photo-polymerizable resin contained in the liquid material is to be hardened by electromagnetic irradiation, and wherein the material application for the subsequent layer automatically results from the separation of the last hardened layer from the construction/-reference plane, whereby the construction/reference plane is formed by an elastic film.

Abstract: A medical device in which a part to be secondarily shaped comprises a molded silicone rubber article is subjected to heatless shaping by irradiation with electron-rays. The irradiation with electron-rays enables shaping and, furthermore, sterilization under some conditions. In a medical device comprising a part in which at least a silicone rubber is used and the mechanical properties of the silicone rubber preferentially appear, the shape of the above-described part upon molding is deformed with the use of a correcting member to a level exceeding the desired deformed shape and maintained in this state. Next, electron-ray irradiation is conducted in this state and then the correcting member is eliminated. Thus, the desired deformed shape intermediate between the shape upon the molding and the shape upon the electron-ray irradiation can be obtained.
