The present invention provides a method for producing a molded body, having the step 1 of applying a composition containing an alicyclic urethane (meth)acrylate to a thermoplastic resin substrate to obtain a coated material, the step 2 of irradiating the obtained coated material with an active energy ray to cure the composition, obtaining a laminated material having a cured product layer obtained from the cured composition, and the step 3 of subjecting the obtained laminated material to bending processing to obtain a molded body, wherein the alicyclic urethane (meth)acrylate has a structure having an alicyclic structure represented by the formula (A), and a group having two or more (meth)acryloyl groups represented by the formula (B), and further has a polymerizable double bond equivalent of 100 to 1,000 g/mol.

Methods produce a three-dimensional dental block of material from a dental, polymerizable material. The methods include at least: transferring the polymerizable dental material into a radiolucent three-dimensional casting or press mold; irradiating the polymerizable dental material substantially from all sides with light in the UV/Ms spectral region forming polymerized outer surfaces of the dental material in the form of a solid outer shell of the dental material, wherein the shell is present in the defined three-dimensional geometry of the material whilst the inner region of the material is not polymerized or partially polymerized; heating the material with solid shell being present in defined three-dimensional geometry, to 60 C. to 150 C. for at least 90 minutes; and obtaining a dental, polymerized block of material having defined three-dimensional geometry.

A hollow fiber membrane is formed by embedding a braid having a spiral open weave of monofilaments only, to avoid a whiskering problem. The open weave is characterized by contiguous, circumferential, rhomboid-shaped areas of polymer film separated by monofilaments. When the braid is supported on a plasticized PVA cable having a scalloped periphery, the braid can be infiltrated with membrane polymer which, when coagulated, embeds the braid positioning it around the lumen. The embedded spiral weave, free of any circumferentially constricting monofilament, allows the membrane to be biaxially distensible. The membrane has give not only in the axial or longitudinal direction but also in the radial direction. Give in the radial direction permits soiled membranes to be backwashed under higher pressure than in a comparable braid which is not radially distensible.

A decorative optical element that has an appearance of a glass optical element includes an optically transparent body having a faceted globular portion defined by a solid volume of polymeric material. A luminaire, such as for a street light, employs the decorative optical element and an LED circuit board mounted to the circuit board.

A filament for use in forming a support structure in fused filament fabrication, the filament comprising an amorphous, thermoplastic resin further comprising Bisphenol Isophorone carbonate units and Bisphenol A carbonate units, wherein the Bisphenol Isophorone carbonate units are 30 to 50 mole percent of the total of Bisphenol A carbonate units and Bisphenol Isophorone carbonate units in the resin, and wherein the resin has a glass transition temperature from 165 C. to 200 C. The composition used to form the support filament exhibits a desirable combination of filament formability, printability, lack of significant oozing from the printer nozzle, and good ease of mechanical separation from the build material at room temperature after printing.

Disclosed herein are methods that includes using a water-degradable (e.g., autoclavable) support material together with a high-heat build material (e.g., polyetherimide or PEI). When the support material is autoclaved for a period of time, the support material becomes brittle and then disintegrates into powder and therefore can be removed from the model or build material, leaving behind a part formed from the model material that includes features (e.g., cavities, channels, etc.) formerly occupied by the support material.

A hot stamping apparatus and a hot stamping method are for collectively decorating a plurality of decoration objects using a decorative sheet. In a hot stamping apparatus, an upper chamber and a lower chamber are partitioned by a partition sheet and pressing bodies, so that decorative sheet pieces can be used instead of a decorative sheet having a large area. Then, by using the decorative sheet pieces, local thermal deformation can be prevented. A usage amount of the decorative sheet can be reduced, and three-dimensional decoration can be implemented as needed on a portion requiring decoration.

The invention relates to a method for producing microstructures, the method including providing a planar mold element, which includes at least one mold opening for the microstructure to be produced, wherein the at least one mold opening has a first opening and a second opening; providing a first formulation at the second opening; generating a negative pressure in the mold opening; and taking up the first formulation through the second opening into the mold opening on account of the negative pressure in the mold opening. The invention further relates to a system for producing microstructures.

A system for thermoforming an object is provided. The system includes a mold and a pressure-box. The mold has a surface that defines a shape of the object and includes two or more portions of differing porosities. The pressure-box is operative to generate a pressure differential across the surface. The two or more portions apply the pressure differential at different loads, based at least in part on the differing porosities, to a material disposed onto the surface so as to form the object by deforming the material into the shape.

Disclosed herein is a multilayered tape comprising a first layer; where the first layer comprises a first surface and second surface; the first surface of the first layer having a surface texture; a second layer; the second layer having a first surface and a second surface; where the first surface of the second layer is closer to the second surface of the first layer than the second surface of the second layer; where the second surface of the second layer contains at least one partition that is parallel to a longitudinal direction of the multilayered tape.
