The invention relates to a dosage form comprising a physiologically effective amount of a physiologically active substance (A), a synthetic, semi-synthetic or natural polymer (C), optionally one or more physiologically acceptable auxiliary substances (B) and optionally a synthetic, semi-synthetic or natural wax (D), wherein the dosage form exhibits a resistance to crushing of at least 400 N and wherein under physiological conditions the release of the physiologically active substance (A) from the dosage form is at least partially delayed.

The present disclosure provides methods for additive manufacturing of a three-dimensional (3D) object, comprising preheating a feed comprising a polymer material to a temperature in excess of a glass transition temperature and below a melting point of the polymer material. The preheating may occur at a first location in an additive manufacturing apparatus. Next, the polymer material may be melted at a second location that is spatially distinct from the first location.

A method for manufacturing a fine hollow protruding article (1) according to the invention involves: a protrusion forming step of bringing a projecting mold part (11) that includes a heating means into contact from one surface (2D) side of a base sheet (2) including a thermoplastic resin, and, while softening, with heat, a contact section (TP) in the base sheet (2) where the projecting mold part (11) contacts the base sheet (2), inserting the projecting mold part (11) into the base sheet (2), to form a protrusion (3) that protrudes from the other surface (2U) side of the base sheet (2); a cooling step of cooling the protrusion (3) in a state where the projecting mold part (11) is inserted in an interior of the protrusion (3); and a release step of withdrawing the projecting mold part (11) from the interior of the protrusion (3) after the cooling step, to form the fine hollow protruding article (1).

A print head is disclosed for use with an additive manufacturing system. The print head may include a nozzle, and a traveling anchor point mounted at a trailing side of the nozzle. The traveling anchor point may include an arm extending radially outward from the nozzle, and a plunger slidingly disposed in the arm. The traveling anchor point may also include an actuator configured to selectively move the plunger from a stowed position to an engaged position against material discharging from the nozzle.

A method of forming an oral care implement, a method of forming a head plate for an oral care implement, and an oral care implement or head plate formed therefrom. The head plate may have micro-sized or fine features. The method may include providing an amount of a first solid material upstream of a first mold cavity; prior to the first solid material entering the first mold cavity, applying ultrasonic energy to the first solid material to melt the first solid material into a first molten material; flowing the first molten material into the first mold cavity; allowing the first molten material to harden within the first mold cavity to form a head plate comprising micro-sized features; forming a body from a second material, the body including a handle portion and a head portion; and coupling the head plate to the head portion of the body.

A polymeric material used for 3D printing is preheated, at a first zone in a 3D printer, to a temperature in excess of its glass transition temperature prior to being melted, at a second zone, for incorporation into a build object. This enables the polymer to be processed more rapidly than in the prior art.

A method of forming an oral care implement, a method of forming a head plate for an oral care implement, and an oral care implement or head plate formed therefrom. The head plate may have micro-sized or fine features. The method may include providing an amount of a first solid material upstream of a first mold cavity; prior to the first solid material entering the first mold cavity, applying ultrasonic energy to the first solid material to melt the first solid material into a first molten material; flowing the first molten material into the first mold cavity; allowing the first molten material to harden within the first mold cavity to form a head plate comprising micro-sized features; forming a body from a second material, the body including a handle portion and a head portion; and coupling the head plate to the head portion of the body.

The invention relates to a dosage form that is thermoformed without discoloration and is safeguarded from abuse, comprising at least one synthetic or natural polymer having a breaking strength of at least 500 N in addition to one or more active substances that could be subject to abuse. The invention also relates to a corresponding method for producing said dosage form.

One example method for producing a component from organic sheets may comprise placing a first organic sheet and a second organic sheet next to one another to form a component preform, forming at least one overlapping joining zone by tacking the first and second organic sheets together with a connecting part in the form of a third organic sheet, transferring the component preform to a joining tool, using the joining tool to form a joined component by connecting the organic sheets through melting and compression in the overlapping joining zone, and consolidating the joined component at least in the zone of the overlapping joining zone.

A method of fastening a second object to a fiber composite part including a structure of fibers embedded in a matrix material includes: providing the fiber composite part including an attachment surface, with a portion of the structure of fibers being exposed at the attachment surface; providing the second object; placing the second object relative to the fiber composite part, with a resin in a flowable state between the attachment surface and the connector; pressing the second object and the fiber composite part against each other and causing mechanical vibration to act on the second object or the fiber composite part or both, thereby causing the resin to infiltrate the exposed structure of fibers and activating the resin to cross-link; whereby the resin, after cross-linking, secures the second object to the fiber composite part.
