Abstract
The use of 3D and 4D printing in a broad range of high-tech sectors (electronics, energy, transport, aerospace, aeronautics, or biomedicine) attracts much interest due to the possibility of fabricating complex objects with reduced restriction in shape. Moreover, this technology allows for designing of devices according to efficiency (high performance, materials usage, diminished environmental impact) instead of according to availability of components. The employment of composite materials in 3D and 4D printing make possible to fabricate advanced multi-functional and smart parts and devices. The combination of different materials such as metal alloys, polymers and ceramics in a suitable proportion leads to advanced materials with tuned physical properties: mechanical reinforced or lightweight structures, and added functionality due to incorporation of electrical, magnetic, and optical properties, among others, to the material. Herein, an overview of the 3D and 4D printing technologies is provided, including the different possibilities on composite development, printing methods and incorporated functionalities.
