Provided are an apparatus and a method of controlling a stiffness of a soft material hardened from a liquid state having viscosity into a solid state. The apparatus of controlling a stiffness of a soft material includes: a soft material accommodating means including a chamber corresponding to a space in which the soft material having fluidity before being hardened is accommodated and a wall structure surrounding the chamber; and a stimulus means applying a stimulus to the soft material to generate a flow in the soft material, wherein a flow is applied to the soft material to control the stiffness in the soft material and control stiffnesses to be different from each other in each region of the soft material.

Methods for manufacturing articles of footwear are provided. In various aspects, the methods comprise utilizing additive manufacturing methods with foam particles. In some aspects, the additive manufacturing methods comprise increasing the temperature of a plurality of foam particles with actinic radiation under conditions effective to fuse a portion of the plurality of foam particles comprising one or more thermoplastic elastomers. Increasing the temperature of the foam particles can be carried out for one or multiple iterations. The disclosed methods can be used to manufacturer articles with sub-regions that exhibit differing degrees of fusion between the foam particles, thereby resulting in sub-regions with different properties such as density, resilience, and/or flexural modulus. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Provided is a three-dimensional object formation method including: a first step of forming a film by delivering a first liquid containing at least water and a hydrogel precursor: and a second step of curing the film formed in the first step, wherein the first step and the second step are repeated a plurality of times.

The present invention is a method for manufacturing inflatable bladders for use in articles of manufacture. The method includes the steps of providing a first polymer film, applying a curable release coating to the polymer film in a pattern that corresponds to the configuration of the inflatable bladder, curing the release coating to the first polymer film, providing a second polymer film with the first polymer film to form a layered element such that the release coating is disposed between the polymer films, positioning the layered element between two plies of material, applying heat and pressure to adhere the polymer films together except in the area where the release coating has been applied to form an inflatable compartment surrounded by a sealed perimeter, and removing the plies of material from the adhered first and second polymer films.

An object of the present invention is to provide a laminated member for decoration that can be molded into a complicated shape and has a superior hardcoating property. The present invention relates to a laminated member for decoration having a protective film, a coating layer and a resin substrate, wherein the surface roughness Rz(a) of the adhesive layer of the protective film on the side where the coating layer is located and the surface roughness Rz(b) of the coating layer of an unheated sample formed by peeling the protective layer, the surface roughness being taken on the side opposite from the resin substrate, define Rz(b)/Rz(a)×100 having a prescribed relationship; the surface roughness Rz(b) and the surface roughness Rz(bh) of the coating layer of a heated sample prepared by heating the unheated sample under a prescribed condition, the surface roughness being taken on the side opposite from the resin substrate, satisfy at least one of Formulas (2) and (3) below:

0%≤Rz(bh)/Rz(b)×100<30%  (2), and

0≤Rz(bh)≤Rz(b)<0.5 μm  (3);

and the unreacted (meth)acryloyl groups of the coating layer of the heated sample irradiated with a prescribed amount of active energy rays have disappeared 10 to 100% as compared with the coating layer of the unheated sample.

An object which the present invention is to achieve is to provide a urethane composition capable of providing a molded product having excellent heat resistance and high hardness. The present invention is to provide a urethane composition containing a main agent (i) including a urethane prepolymer having an isocyanate group obtained by allowing a polyol (A) and a polyisocyanate (B) to react with each other, and a curing agent (ii), in which the polyol (A) includes a polyether polyol (a1) obtained by polymerizing an aromatic compound (a1-1) having two or more active hydrogen atom-containing groups and an alkylene oxide (a1-2), and a polishing material obtained by curing the urethane composition with heat, followed by slicing.

Systems and methods of manufacturing 3D printed medical devices. The method includes feeding a first filament and a second filament into an interior cavity of a heating cartridge and melting each of the filaments on a substrate. The heating cartridge is then moved linearly and rotationally relative to the substrate to form a jacket including material from each of the first and second filaments. Further, rotating the substrate provides a uniform mixture and creates support rings between the filament materials within the structure of the jacket.
