An injection-moulded piece that has a plastic base layer, a transparent or translucent cover layer, and a layer containing individual decorative elements located between the base and cover layers. The decorative elements are at least partly embedded both in the cover layer and in the base layer. The method for producing the injection-moulded piece, wherein decorative elements are placed on a sticky cover layer and a base layer is applied to the decorative elements by injection moulding. The individual decorative elements are applied to the sticky surface of the cover layer, by a random process, and if required, a second cover layer is applied, the decorative elements are at least partly embedded in the cover layer, waiting for the cover layer to dry, and a base layer is applied to the decorative elements by injection moulding so that the base layer embeds the remaining part of the decorative elements.

An aluminum-based metal-resin composite structure (106) includes an aluminum-based metal member (103) in which a dendritic layer (103-2) is formed on at least a part of a surface, and a resin member (105) bonded to the aluminum-based metal member (103) via the dendritic layer (103-2) and formed of a thermoplastic resin composition, in which, when analysis is conducted with a Fourier transform infrared spectrophotometer (FTIR) on a surface (104) of a bonding portion with at least the resin member (105) in the aluminum-based metal member (103) and an absorbance of an absorption peak observed at 3400 cm.sup.−1 is defined as A.sub.1 and an absorbance at 3400 cm.sup.−1 of a straight line connecting an absorbance at 3800 cm.sup.−1 and an absorbance at 2500 cm.sup.−1 is defined as A.sub.0, an absorbance difference (A.sub.1−A.sub.0) is in a range of 0.03 or less.

A composite structure comprises stacked sets of laminated fiber reinforced resin plies and metal sheets. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.

A method of forming multilayer polymer composite particles includes coextruding a multilayer polymer composite sheet having alternating first and second polymer layers. The multilayer polymer composite sheet is divided into a plurality of anisotropic multilayer polymer composite microparticles.

A powder-based additive manufacturing installation (10) comprises a powder layering device (14) that can be displaced along a path linking a start zone (A) and an end zone (B). The layering device (14) comprises powder smoothing means (35) for depositing powder in a powder deposition zone (P) situated between the start zone (A) and the end zone (B). The installation furthermore comprises a cleaning device (60) situated on the path of the layering device (14), the cleaning device (60) comprising a brushing device (62) for brushing at least one surface of the powder smoothing means (35).
