“…The important advantage of the MJT process is the multi-color printing, a particularity that Tsai and coauthors have experimented with by developing a piezoelectric print head with six nozzles, one for constructing the support and each of the others for a different color. This study showed the possibility of manufacturing a three-dimensional part [72]. In order to reduce the cost of printing, it is recommended to print several parts in one construction and by minimizing the use of support material given its cost, which is very high [56].…”

Nascent technologies develop and mature over time. Research and development conducted throughout time led to innovation activity that can create new emerging technologies that disturb and upset the usual systems. AM is currently following this path. Invented in the 1980s, it is, nowadays, reaching its maturity, taking into account the changes it brings to the industrial field and the added value it is creating [1]. This technique can create radically new solutions or change the initial system architecture. The principle is to manufacture an object by printing according to a digital model, layer by layer, until obtaining a three-dimensional (3D) part involving different materials and processes. Developed first for rapid prototyping, it currently enables producing functional end-use parts. The expiration of specific patents, in addition to new materials developed, and innovative AM techniques have resulted in the emergence of new applications that have pushed the adoption of this technique by decision-makers [2].

“…In this regard, horn antennas are proposed, where the gain can be increased by enlarging the radiating aperture and the costs and weights can be reduced by using additive manufacturing techniques such as 3D printing [ 6 ]. There are multiple printing methods, such as selective laser sintering (SLS) [ 7 ], where a laser selectively sinters the particles of a polymer powder, fusing them together and building a part layer by layer; fused deposition modeling (FDM) [ 8 ], where molten plastic is extruded from a computer-controlled hot-end and cooled to form a part; stereolithography (SLA) [ 9 ], where a light source is used to selectively harden photo-activated resins; material jetting (MJ) [ 10 ], where the printheads are used to deposit a liquid photoreactive material onto a build platform layer upon layer; and direct metal laser sintering (DMLS) [ 11 ], similar to FDM but with a metallic powder. In [ 12 ], a fully 3D-printed complex corporate feeding network with 256 horns was successfully manufactured using DMLS, but the cost was high.…”

A 3D-printed phased array consisting of four H-Sectorial horn antennas of 200 g weight with an ultra-wideband rectangular-waveguide-to-microstrip-line transition operating over the whole LMDS and K bands (24.25–29.5 GHz) is presented. The transition is based on exciting three overlapped transversal patches that radiate into the waveguide. The transition provides very low insertion losses, ranging from 0.30 dB to 0.67 dB over the whole band of operation (23.5–30.4 GHz). The measured fractional bandwidth of the phased array including the transition was 20.8% (24.75–30.3 GHz). The antenna was measured for six different scanning angles corresponding to six different progressive phases α, ranging from 0° to 140° at the central frequency band of operation of 26.5 GHz. The maximum gain was found in the broadside direction α = 0°, with 15.2 dB and efficiency η = 78.5%, while the minimum was found for α = 140°, with 13.7 dB and η = 91.2%.

“…In particular, among the various 3D printing methods, research cases using the photocatalytic reaction method, which can lower equipment costs while maintaining high resolution and good surface quality, have been published extensively [18,19]. Among the photo-catalytic reaction methods, material jetting (MJ) is based on an inkjet structure, meaning it has advantages in terms of the printing quality and material diversity through the use of multiple nozzles [20]; however, in the MJ method, since the material is sprayed through a fine nozzle and then cured by ultraviolet light as is, if a material is used with physical properties that are difficult to control, the quality is greatly reduced [21]. In addition, if a composite material containing powder is used, abrasion and clogging of the fine nozzle may occur due to the powder; that is, since most of the composite materials used for 3D printing contain various functional powder materials, the viscosity of the resin used increases and aggregation occurs, which makes it difficult to use them in MJ 3D printing.…”

Additive manufacturing, commonly called 3D printing, has been studied extensively because it can be used to fabricate complex structures; however, polymer-based 3D printing has limitations in terms of implementing certain functionalities, so it is limited in the production of conceptual prototypes. As such, polymer-based composites and multi-material 3D printing are being studied as alternatives. In this study, a DLP 3D printer capable of printing multiple composite materials was fabricated using a movable separator and structures with various properties were fabricated by selectively printing two composite materials. After the specimen was fabricated based on the ASTM, the basic mechanical properties of the structure were compared through a 3-point bending test and a ball rebound test. Through this, it was shown that structures with various mechanical properties can be fabricated using the proposed movable-separator-based DLP process. In addition, it was shown that this process can be used to fabricate anisotropic structures, whose properties vary depending on the direction of the force applied to the structure. By fabricating multi-joint grippers with varying levels of flexibility, it was shown that the proposed process can be applied in the fabrication of soft robots as well.
