3D printing is considered one of the technologies that will change the world in the next future. The capability of producing series of free‐shape customized objects using almost all relevant families of materials (plastics, metals, and ceramics) is considered a revolution in the field of manufacturing, especially because it can be done even by individuals. The low investment required for simple 3D printers and the open availability of design files make this technology an entire change in the way of understanding product fabrication and prototyping.
At a first stage, 3D printing was mainly developed for structural parts made of plastics but, nowadays, the technology evolved into a complete additive manufacturing chain, covering design, simulation, optimization, fabrication and rapid prototyping of functional objects as well as complete devices made of metals and ceramics. This evolution represents an enormous competitive advantage since the fabrication of high value‐added products such as devices and functional parts will open the use of this technology to the vast majority of application scenarios and industrial sectors, including the energy field.
Moreover, a real deployment of 3D printing of functional materials will benefit in promoting a circular economy by preventing the loss of valuable materials and reducing the energy consumption in the manufacturing process. In general, the uses of additive manufacturing techniques can represent a reduction of up to 80% of waste material and 70% of energy consumption. Besides, 3D printing promotes the simplification of the manufacturing processes as well as reducing the environmental impact of distribution. This decentralized manufacturing approach combined with the open distribution of digital models will represent a technological revolution that might bring marginal costs to near zero, if raw materials are widely available.
I.1 3D Printing Technologies
3D printing allows the fabrication of three‐dimensional objects by deposition of successive layers of material using a digital model. Intensive research on additive manufacturing has been carried out during the last decades to allow the fabrication of three dimensional objects by assembling material without the use of tooling or molds. 3D printing started in 1981 at Nagoya Municipal Industrial Research Institute publishes, where Hideo Kodama reported the first photopolymer system. Based on the Kodama's concept, Charles developed in 1984 the stereolithography (SLA) printer based on photopolymers. The first FDM (fused deposition modeling) machine was developed in the 1990s. FDM is based on the extrusion of melting plastic filaments that is deposit as a thread layers on a print bed. In 1992, SLA evolves into SLS (selective laser sintering) machine, where powder and lasers replace the photopolymers and the UV light, respectively. Further development took place, in 1997, into the first laser additive manufacturing. In 2000, the already consolidated inkjet printing converges toward 3D printing methods, evolving into the first 3D inkjet printer for drop‐by‐drop deposition of complex object and vertical extension.
