![]() ![]() Both surface and bulk functionalization of the basic materials may lead to final devices with enhanced properties and innovative functionalities. Consequently, finding alternative methods that allow improving the mechanical, thermal and electrical properties of materials employed in additive manufacturing is a relevant field of study with industrial and scientific significance. For these reasons, additive technologies are reinventing production processes and enabling the rapid production of innovative products and complex geometries, thanks to the layer-by-layer approach, with a degree of complexity that cannot be matched by more traditional methods and techniques, although the final performance of manufactured parts is not always as perfect as that obtained with traditional procedures. In a way, the straightforward solid free-form fabrication of complex objects and the sustainable production without much debris and in a wide set of materials are promoted. ![]() In additive manufacturing processes (commonly called 3D printing), the object is constructed in a more controlled form, using only the exact amount of material, which is deposited layer by layer, following a design obtained with a CAD program (computer-aided design). In traditional manufacturing methods, typically based on subtractive approaches, the objects are manufactured by eliminating material from a preform with limited geometrical complexity, according to the established requirements, and usually generating a lot of waste.
