The invention relates to the use of mixtures of water and essential oils selected from the group consisting of phenols, phenylpropanoids and furanocoumarins, for separating multilayered composites for the segregated recycling of polymer/metal films.

The invention relates to a process for the production of at least two-layer thermoplastic sheets via thermal welding of at least one thinner thermoplastic sheet with density (D1) and of at least one second thinner thermoplastic sheet with density (D2), where the density (D1) of the first thinner thermoplastic sheet is smaller than the density (D2) of the second thinner thermoplastic sheet.

In a second layer provided above the first layer, the first resin materials are continuously formed in a third direction intersecting the first direction and arranged with a gap between the first resin materials in a fourth direction intersecting the third direction, and the resin materials other than the first resin materials are continuously formed in the third direction and arranged in the gap.

Disclosed is a device for manufacturing a skin-simulating phantom, which has properties that are similar to those of real skin, using a 3D printer so that layers are stacked to form a multi-layered structure and a nozzle tip connected to the 3D printer is used to provide roughness, and a method of manufacturing a skin-simulating phantom using the same. According to this present invention, solutions can be mixed, depending on the component constitution reflecting the optical properties of the skin, using a program that is set depending on the type of skin. The output condition of the 3D printer can be controlled using a program that is set so as to conduct a step of comparing measured thickness and roughness values to those of the real skin and performing feedback. The nozzle tip connected to the 3D printer can move up and down to provide roughness. Further, the multi-layered structure can be manufactured using the 3D printer, thereby outputting and embodying lesions.

The current three-dimensional object manufacturing technique relies on the deposition of a pseudoplastic flame retardant material in gel aggregate state. The gel flows through a deposition nozzle because the applied agitation and pressure shears the bonds and induces a breakdown in the material elasticity. The elasticity recovers immediately after leaving the nozzle, and the gel solidifies to maintain its shape and strength.
