A print head is disclosed for use with an additive manufacturing system. The print head may include a matrix reservoir, and a nozzle base connected to an end of the matrix reservoir. The nozzle base may have a plurality of attachment features formed within an exposed surface. The print head may further include a plurality of available dies separately connectable to the nozzle base via the plurality of attachment features. Attachment of the plurality of available dies to the nozzle base may establish fluid communication with the matrix reservoir.

A microprotrusion device (1A) according to the present invention includes a needle-like and hollow first protrusion portion (3) that is formed so as to protrude from one surface (2a) of a substrate sheet (2) and a hollow second protrusion portion (4) that is formed so as to protrude from a vicinity of the first protrusion portion (3) on the one surface (2a) of the substrate sheet (2) and has a protrusion height lower than that of the first protrusion portion (3). The first protrusion portion (3) has an opening at its tip end portion, and a hollow portion (30) of the first protrusion portion (3) is in communication with the outside via the opening portion (31). The opening portion (31) is formed at the tip end of the first protrusion portion (3).

A matrix supply is disclosed for use with an additive manufacturing system. The matrix supply may include a matrix chamber configured to fluidly communicate a liquid matrix with a print head of the additive manufacturing system. The matrix supply may also include a supply conduit fluidly connected to the matrix chamber, a valve disposed within the supply conduit, and an inlet configured to pass a continuous reinforcement through the matrix chamber to the print head of the additive manufacturing system.

An injection molding method uses a die with a cavity into which molten resin is to be injected to fill the cavity. The die has a shape that causes the molten resin injected into the cavity to branch and merge. The injection molding method includes providing bubbles into the molten resin before the molten resin is injected, generating fine bubbles with the provided bubbles before the molten resin is injected, injecting the molten resin containing the fine bubbles, and bursting the fine bubbles of the injected molten resin containing the fine bubbles in a merging location where the molten resin merges.

Provided is a printing apparatus using acoustic levitation, the printing apparatus including an acoustic levitation unit, which includes at least one acoustic wave generator and is configured to generate an acoustic field to levitate at least one printing material and form print layers having specific patterns; a material supply unit configured to supply the printing material; and a placing unit including a plate, wherein the print layers are sequentially stacked on the plate.

A method for manufacturing a hollow protruding implement (1) including a fine hollow protrusion (3) having an opening (3h) of the present invention includes a protrusion forming step of inserting a projecting mold part (11) into a base material sheet (2A) from one face (2D) side thereof, the base material sheet containing a thermoplastic resin, thereby forming a non-penetrated hollow protrusion (3) projecting from another face (2U) side of the base material sheet (2A). Subsequently, an opening forming step is performed in which an opening (3h) that penetrates the hollow protrusion (3) is formed by using a contactless opening forming means disposed on the other face (2U) side of the base material sheet (2A).

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.

A method can be used to attach a fabric member to a trim while forming a pattern in the fabric member. A trim has trim grooves formed in one side of the trim and a fabric member has a foam formed in one side of a skin material of the fabric member. A bonding member is coated to an outer surface of the foam and the fabric member is heated where the bonding member is coated. The heated fabric member is placed on the side of the trim where the trim grooves are formed. The fabric member is fixed to the trim by inserting edges of the fabric member into the trim grooves using insertion blades while pattern protrusions formed in a compression jig form a pattern by pressing the skin material of the fabric member.
