The present disclosure relates to method of making three-dimensional (3D) objects using an additive manufacturing system wherein the part material comprises a polymeric component comprising a poly(biphenyl ether sulfone) polymer (PPSU) having an optimized weight average molecular weight (Mw). In particular, the present disclosure relates to part material incorporating a PPSU of Mw ranging from 48,000 to 52,000 g/mol, for example in the form of filaments or spherical particles, for use in additive manufacturing systems to print 3D objects.

Using a memory that manages a user log including at least a cooking time and a food to be cooked with a cooking device used by each user in a plurality of users, a recommended cooking time corresponding to a first user's food to be cooked included in recommended cooking times for respective foods calculated based on cooking times with the cooking devices is acquired from a server, a user interface that prompts the first user to select one of candidates of cooking times including at least the recommended cooking times is displayed on a display, and in response to detecting that a cooking time is selected by performing an input operation on the user interface, a setting command to set the selected cooking time is output to the first cooking device.

An improved inside of can curing technology is provided. One implementation uses narrowband, semiconductor produced infrared energy which is focused into the inside of the can to affect a very high-speed curing result. It uses focused high powered, radiant energy that will directly impact the coating covering the inside walls of the can to rapidly cure the coating. The curing is accomplished so rapidly that the de-tempering and annealing of the aluminum can body does not have time to occur, thus leaving a stronger can. It is therefore possible to make either a stronger can with the same amount of aluminum or a can of the same strength but with less aluminum. It is also possible to eliminate the natural gas fueled oven that is the current standard and replace it with a completely hydrocarbon-free curing alternative that has superior performance. This high powered radiant, narrowband energy will be introduced directly into each individual can where it will rapidly cure the inside coating while being completely and dynamically digitally controlled to introduce only the needed heat and to not overheat the can.

Disclosed herein are methods of forming a three-dimensional object having a biodegradable or bioerodible polymer or copolymer. In some embodiments, the methods include providing a dual cure resin with a photoinitiator, monomers and/or prepolymers that are polymerizable by exposure to actinic radiation or light, at least one cyclic ester, a ring-opening polymerization initiator, and a ring-opening polymerization catalyst. Resins useful for carrying out such methods, and products produced from such methods, are also described.

A food vending machine has a food-preparing device and a storage device. The storage device is connected with the food-preparing device and has serving openings and a transmission mechanism. The transmission mechanism has multiple loading assemblies capable of moving along a transmission route. A food-serving method includes an ordering process, a preparing process, and a serving process. A consumer may choose later pick-up and optionally specify a pick-up time. Then, if the consumer chooses later pick-up but does not specify a pick-up time, the storage device serves the meal; if the consumer chooses later pick-up and specifies a pick-up time, the food-preparing device serves the meal, but the meal will be conveyed to the storage device after a pre-set time. Thus, a waiting time of the consumer may be reduced, and a formerly ordered but not-yet-picked-up meal may not interfere with a later consumer.

A magnetocaloric structure incorporating magnetocaloric material for inclusion in an electrical transmission line conductor, such that the magnetic Held generated by alternating current transmission cause the magnetocaloric material to exhibit a magnetocaloric effect. Also provided is an electrical power transmission line conductor comprising a bundle of at least one electrical conductor configured for transmission of high voltage alternating current electrical power, at least one strengthening structure bundled with the electrical conductor to provide physical support to the electrical conductor, and at least one magnetocaloric structure comprising magnetocaloric material.
