A computer-implemented method for dividing a virtual three-dimensional overall model of a body into at least two virtual partial models, includes: Creating a virtual separating surface for the overall model of the body, which has a three-dimensional cell-conforming shape; Creating the overall model of the body with a lattice structure formed from a plurality of cells; and Dividing the overall model along the cell-conforming separating surface into two partial models, so that when the overall model is divided, common struts of the lattice structure, which are each part of at least one cell of one partial model and part of at least one adjacent cell of the other partial model are divided by means of the cell-conforming separating surface in such a way that the corresponding cells remain closed.

A method for producing a composite body from at least two partial bodies, at least one of the partial bodies being produced in an additive manufacturing process, includes exposing the at least two partial bodies to a solvent atmosphere, so that one surface of the partial body is smoothed. The at least two partial bodies are placed in the chamber in such a way that they touch at least one joining surface and that the solvent atmosphere creates a material connection between the at least two partial bodies on the at least one joining surface.

Example fluid impermeable barriers of fluid collection devices and methods of forming a fluid impermeable barrier of a fluid collection device. The fluid impermeable barrier includes an inner surface at least partially defining a chamber, a first end region defining an aperture extending therethrough and including a first outer surface portion, and a second end region distal to the first end region and including a second outer surface portion having more adhesive strength than the first outer surface portion. The fluid impermeable barrier also defines an opening extending longitudinally along the fluid impermeable barrier and configured to be positioned adjacent to a female urethra.

Provided is a syringe gasket including a first member, and a second member connected to the first member and coupled to a plunger rod of a syringe. The first member includes a top face contacting with the liquid, and a first side circumferential face that faces an inner circumferential face of a barrel of the syringe. The first side circumferential face has, at an end portion thereof close to the second member, a ring-like trimmed face. An inert film is laminated on the top face and the portion of the first side circumferential face other than the ring-like trimmed face. The second member includes a second side circumferential face that faces the inner circumferential face of the barrel, and a ring-like protruding portion that projects outward in the radial direction from the second side circumferential face. The ring-like protruding portion at least partially covers the ring-like trimmed face.

Foamed articles including a foamed thermoplastic elastomeric material, methods of making the articles, and methods for manufacturing articles of footwear, apparel, and athletic equipment incorporating the articles are provided. One exemplary method for making a foamed article comprises placing an article comprising a foamable material and carbon dioxide in a vessel, the foamable material; maintaining the vessel at a first pressure and first temperature at which the carbon dioxide is a liquid and carbon dioxide is soluble in the foamable material; optionally exposing the infused article to a second temperature and second pressure; and subjecting the article to a third pressure and third temperature at which the infused carbon dioxide phase transitions to a gas, thereby expanding the foamable material into a foamed material and forming the foamed article.

The method includes the step of forming a carcass from at least one first material based on a thermoplastic elastomer. The method continues with the step of forming, on the carcass, at least bead zone from at least one second material based on a thermoplastic elastomer to form an assembly. The method proceeds with the step of forming, on the assembly an additional part from at least one third material based on a thermoplastic elastomer.
