A method of manufacturing a shoe structure includes: a setting step of setting an upper on a shoe last, and distributing a foam matrix material comprising a plurality of semi-foamed granules of thermoplastic polyurethanes (TPU) along a bottom of the shoe last to position the foam matrix material between the shoe last and the upper, and a foaming step of heating the shoe last with the upper and the foam matrix material thereon by microwave, so that the semi-foamed granules are foamed to form an insole bonded to the upper, and the upper is shaped along a contour of the shoe last after cooling and removing the shoe last.

The scope of this invention is to disclose the method of foaming a superior impact mitigation material, namely semi-closed cell hybrid polyurea foam, using scalable manufacturing process that is geometry-independent and allows for greater control of the resulting foam properties. while the process discussed herein, can be easily used to make complex geometries (e.g., padding foam for helmets, outsoles for walking and running shoes, body armors or other protection applications.

A method of forming a three-dimensional object is described. The method may use a polymerizable liquid, or resin, useful for the production by additive manufacturing of a three-dimensional object, comprising a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from said first component.

Provided is method of making a three-dimensional object comprising polyurea, which may include: (a) dispensing a one part (1K) dual cure resin into a stereolithography apparatus, the resin comprising or consisting essentially of a photoinitiator, a reactive blocked polyisocyanate, optionally a catalyst such as a polyurethane blowing catalyst, and optionally a polyepoxide; (b) additively manufacturing from said resin an intermediate object comprising the light polymerization product of said reactive blocked polyisocyanate; (c) optionally cleaning said intermediate object; and (d) reacting said polymerization product in said intermediate with water in the presence of a catalyst such as a polyurethane blowing catalyst (which may be included in the resin, the water, or both) to generate polyamine in situ that sequentially reacts with the remainder of the polymerization product to form urea linkages and thereby produce a three-dimensional object comprising polyurea. Dual cure resins useful for the method are also provided.

A method of forming a three-dimensional object is carried out by: (a) providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; (b) filling the build region with a polymerizable liquid, the polymerizable liquid including a mixture of (i) a light polymerizable liquid first component, and (ii) a second solidifiable component that is different from the first component; (c) irradiating the build region with light through the optically transparent member to form a solid polymer scaffold from the first component and also advancing the carrier away from the build surface to form a three-dimensional intermediate having the same shape as, or a shape to be imparted to, the three-dimensional object, and containing the second solidifiable component carried in the scaffold in unsolidified and/or uncured form; and (d) concurrently with or subsequent to the irradiating step, solidifying and/or curing the second solidifiable component in the three-dimensional intermediate to form the three-dimensional object.

Methods of printing a three-dimensional object using co-reactive components are disclosed. Thermosetting compositions for three-dimensional printing are also disclosed.

A method of manufacturing a shoe structure includes: a setting step of setting an upper on a shoe last, and distributing a foam matrix material comprising a plurality of semi-foamed granules of thermoplastic polyurethanes (TPU) along a bottom of the shoe last to position the foam matrix material between the shoe last and the upper, and a foaming step of heating the shoe last with the upper and the foam matrix material thereon by microwave, so that the semi-foamed granules are foamed to form an insole bonded to the upper, and the upper is shaped along a contour of the shoe last after cooling and removing the shoe last.

A method for producing a component, wherein in the method the following steps are carried out, in particular in the following sequence: providing at least one upper mold carrier and at least one lower mold carrier, wherein the at least one upper mold carrier has at least two upper mold modules and the at least one lower mold carrier has at least one lower mold module; moving the at least one upper mold carrier and/or the at least one lower mold carrier in at least one direction into at least one predetermined position; combining a first upper mold module of the at least two upper mold modules of the at least one upper mold carrier and a first lower mold module of the at least one first lower mold module of the at least one lower mold carrier in the at least one predetermined position such that one or more work stations for carrying out at least one step for producing the component are formed; carrying out the at least one production step to form the component, as well as a device for producing a component.

The present invention relates to a booster seat comprising a seat shell with a lower face for supporting the seat shell and an upper face, on which a seat base and lateral seat cushion regions and backrest regions that delimit the seat base laterally and rearwards are provided. The lower face of the seat shell has a stacking contour which is designed to provide a stacking capability on the upper face of the seat shell. The invention also relates to a booster seat comprising a strap system that has four eyelets, wherein one retaining strap is allocated to a pair of eyelets. Two eyelets are arranged in the front outer region of each lateral seat cushion region, while two eyelets are arranged in the rear outer region of each lateral seat cushion region or in the lateral outer region of the back region. The invention further relates to a method for producing a booster seat of this type.

A plastic carrier for sealing a mold cavity during the production of a multicomponent plastic part, wherein at least one component flows over a plastic element and the carrier, with the carrier becoming an integral part of the multicomponent plastic part. The carrier has a central region sealing the mold cavity when the plastic element is inserted into the mold cavity, a first main face facing the mold cavity and a second main face facing away from the first main face. The carrier has a peripheral edge extending beyond the central region and the outer circumference of the mold cavity, allowing the at least one component to flow over the first main face of the peripheral edge. The carrier also has a first edge region forming a fold-over projection and a second edge region arranged between the central region and the first edge region for forming a film hinge.
