Shape memory polymer (SMP) epoxies and composites, and methods of manufacturing the same, are provided. A three-dimensional (3D) printing technique can be used to fabricate a pure thermoset SMP epoxy. A cryogenic sprayer assisted extrusion type 3D printing method can be used to print SMP epoxies and composites of an SMP epoxy and a nanomaterial additive, such as graphene nanoplatelets (GNP).

Method for cooling a three-dimensional object (2) manufactured by layer-wise selective solidification of a pulverulent building material (15) and non-solidified building material (13) in which the three-dimensional object (2) is embedded by a treatment with a fluid medium. The fluid medium is constituted by a carrier gas that is specifically enriched with an additional component which comprises a further gas and/or a liquid and/or by a gas mixture from which specifically at least one mixture components is at least partially withdrawn.

Provided is a cooling device using the vaporization heat of water, the cooling device capable of eliminating the need for a continuous supply of a large amount of water from the outside and reducing an environmental load. A cooling device 1 which cools a cooling target object 3 using vaporization heat of water includes: an air circulation mechanism 10 including an air circulation path 11 including a target object cooling section 11a for cooling the cooling target object 3 with the air mixed with the atomized water and an air cooling section 11b for cooling the heated air; and a water circulation mechanism 20 including a discharge portion 21 for discharging the water in the target object cooling section 11b, a tank 22 for collecting water condensed in the air cooling section 10b, and a pump 22 for delivering the water in the tank 22 to the discharge portion 21.

A method and an apparatus for cooling of casting molds, in particular for cooling of casting molds for cosmetic products, are described. The apparatus comprises at least one housing with at least one opening for at least partly inserting of at least one casting mold in the at least one housing. It further comprises at least one nozzle for generating of a humid mist within the at least one housing by mixing a gaseous and a liquid medium and for causing a convection within the at least one housing by introducing only the gaseous medium in the at least one housing.

A method of after-cooling of the bases of blown out containers, wherein after the transfer of the blown out containers from a blow molding machine to a run-out star wheel which directly follows the blow molding machine along a conveying direction of the containers a cooling of the bases of the containers is carried out by at least one apparatus for cooling the bases. The cooling of the bases of the containers starts immediately during a time interval of at least 0.1 seconds and at most 2 seconds after a pressure release of the containers by the blow molding machine after the blowing out.
