The invention relates to a method for producing a treated object, comprising the steps: a) producing an object by means of additive manufacturing, the object being produced by the repeated arrangement, layer by layer, of at least one first material on a substrate spatially selectively in accordance with a cross-section of the object, the method comprising the additional method step: b) at least partially bringing the object, which is still on the substrate or has already been detached from the substrate and which has been produced by additive manufacturing, into contact with a liquid heated to ≥T or a powder bed of a second material heated to ≥T for a time ≥1 minute in order to obtain the treated object, T standing for a temperature of ≥25° C. The invention further relates to an object produced by a method of this type.

This invention relates to a treatment process for a material chosen from among a polyamide, a polyester and a poly(meth)acrylate.

According to the invention, this process comprises a step in which contact is made between this material and a polar organic solvent in a supercritical fluid.

This invention also relates to a process for manufacturing a part from a material chosen from among a polyamide, a polyester and a poly(meth)acrylate in a divided form.

Finally, the invention relates to use of the material treated by the treatment process and to use of the part manufactured by the manufacturing process in the low voltage, medium voltage or high voltage electrical industry.

The present invention relates to a process for treating a polyamide-based material comprising silica fibers and/or fillers, by impregnation with at least one hydrophobic additive in supercritical CO.sub.2. The invention also relates to a polyamide-based material comprising silica fibers and/or fillers and impregnated with at least one hydrophobic additive, obtained via such a process, and to the use thereof as an electrically insulating component in an electrical device, in particular in a circuit breaker.

A method of modifying a coating material includes applying a fluid including a population of particles to a wet coating material disposed on a substrate. The method also includes drying the wet coating material so as to give rise to a coated article, where the particles are at least partially embedded in a surface of the dried coating material. The particles can be metallic nanowires, and a loading of the metallic nanowires in the dried coating material can be above an electric percolation threshold.

The method of manufacturing a transparent whitening tray according to the present invention includes 3D printing of the whitening tray using the composition for forming a transparent whitening tray as a raw material (S10), removing uncured resin and liquid from the whitening tray obtained in the above step (S20), post-curing the whitening tray obtained in the above step (S30), post-heat treating the whitening tray obtained in the above step (S40), and washing the whitening tray obtained in the above step (S40).
