An additive manufacturing method, an additive manufacturing system (1200), a support material for additive manufacturing, an assembly of the support material and a structure material, and a product thereof are provided. The method comprises depositing, by a nozzle (1210a), a structure material into a support material based on a computer model of an object, thereby forming a portion of the object. Image data of at least the portion of the object can be obtained in-process by a detector (1240). The image data is compared to the computer model. Based on the comparison, the method can comprise modifying the computer model, modifying a print parameter, modifying machine path instructions for an additive manufacturing machine that comprises the nozzle, aborting the additive formation, indicating a discrepancy, indicating validation of the shape, or a combination thereof. The depositing of the structure material is repeated by the nozzle (1210a) as necessary to additively form the object.

A method of manufacturing a separate and continuous layer being essentially uncured. The method includes applying a powder mix including fibres and a thermosetting binder on a carrier, forming a powder mix layer, wherein the powder mix is connected together such that the powder mix layer is obtained and wherein the powder mix layer is essentially uncured, and releasing the powder mix layer from the carrier. Also, a layer and a method for manufacturing a building panel.

A system is disclosed for additively manufacturing a composite structure. The system may include a support, and a print head connected to and moveable by the support. The print head may have an outlet configured to discharge a continuous reinforcement at least partially coated in a matrix, and a device located inside the print head and configured to at least partially coat the continuous reinforcement with the matrix. The system may also include a sensor configured to generate a signal indicative of an amount of the matrix, and a controller in communication with the sensor and the device. The controller may be configured to direct a command to the device to cause the device to advance matrix toward the continuous reinforcement during passage of the continuous reinforcement through the print head, and to selectively adjust the command based on the signal.

Described herein is a cost-effective and time-efficient method for producing UV- and HEVL-absorbing silicone hydrogel contact lenses capable of blocking ultra-violet (“UV”) radiation and high-energy-violet light (HEVL) with wavelengths from 380 nm to 440 nm, thereby protecting eyes to some extent from damages caused by UV and HEVL radiation. This invention also provides UV- and HEVL-absorbing absorbing contact lenses made according to a method of the invention.

A cylindrical winding body is formed by winding continuous fibers impregnated with a first thermosetting resin in a circumferential direction, and the first thermosetting resin in the winding body is thermally cured. A pair of dome members is joined to both end portions of the cylinder member. A fiber bundle impregnated with a second thermosetting resin is helically wound around the joined member over the dome members, and the second thermosetting resin in the wound fiber bundle is thermally cured. A thermosetting resin containing a main agent and a granular solid curing agent is used as the first thermosetting resin, the main agent including a resin precursor and the solid curing agent chemically bonding molecules of the resin precursor together.

A method for producing embedded hydrogel contact lenses comprises at least the following steps: obtaining an insert made of a crosslinked polymeric material comprising iniferter moieties covalently attached thereto; placing the insert in a female lens mold half; dosing an amount of a lens-forming composition to immerse the insert in the female lens mold half; closing tightly a male lens mold half onto the top of the female lens mold half halves to form a molding assembly; curing the lens-forming composition in the molding assembly to form an embedded hydrogel lens precursor which comprises a bulk hydrogel material formed the lens-forming composition and the insert that is embedded therein and covalently linked to the bulk hydrogel material.

The invention relates to a method for producing embedded hydrogel contact lenses each having an insert that comprises alignment features capable of capable of aligning the insert in depth and radial position in a female mold half during cast molding of an embedded hydrogel contact lens. The alignment features protrude from the front surface, are rotationally symmetric with respect to the central axis of the insert and independently have a shape having a curvature being greater than 2 folds of the curvature of the molding surface so as to minimize contacting area between the alignment features and the molding surface. The use of such an insert can simplify the process for producing embedded hydrogel contact lenses and enable the process to be implemented readily in an automatic production.

A method for manufacturing a luggage formed by composite material includes the steps: A) using a vacuum molding method to make a thermoplastic sheet into a shell; B) placing the shell in an inner cavity mold area of a heating mold to correspond the outer surface of the shell to the inner wall surface of the inner cavity mold area; C) setting the outer surface of the thermosetting carbon fiber plastic layer on the inner surface of the shell ; D) setting the reinforcing layer on the inner surface of the thermosetting carbon fiber plastic layer at the location corresponding to the corner of the shell; and E) placing an airbag in the receiving area of the shell and inflating the airbag to support the inner surface of the thermosetting carbon fiber plastic layer and the reinforcing layer.

A three-dimensional object comprises stacked substrate layers infiltrated by a hardened material. Each substrate layer is a sheet-like structure that comprises fibers held together by a sodium silicate binder. The substrate layer material may be non-woven or woven. The substrate layer may be a non-woven fiber veil bound by a sodium silicate binder. The fibers may optionally include carbon fibers, ceramic fibers, polymer fibers, glass fibers, metal fibers, or a combination thereof.
