“…More advanced examples include the incorporation of other functions into the same part (e.g. incorporating electronics into the part directly (Juhasz et al 2020) allowing digital monitoring of the construction). Advanced manufacturing allows the incorporation of properties that were not possible using low-cost construction materials such as specifically designed porous structures for improved air-flow and thermal management, structures with vibration or shock absorption capabilities and more.…”

“…The advantages and limitations are related to the behaviour that the structure presents about the type of embedded sensor used. The monitoring by ESs of components manufactured with metallic materials is a more complex when compared to the components obtained with composite materials [76,[122][123][124][125][126]. In this sequence, technological processes such as laser-assisted metal deposition, low-temperature processes, magnetron sputtering and electroplating [76,123,126], ultrasonic metal welding [122,124], and a hybrid manufactured metal process with an in-situ process interruption [125] are used to incorporate sensors or materials that allow continuous monitoring.…”

“…Juhasz et al [125] described the implementation of an internal passive sensor printed on a hybrid manufactured metal structure during an in-situ process interruption. This hybrid process was combining the benefits of traditional manufacturing (machining) with additive manufacturing, resulting in more complex structures made of several materials, being this combination one of the main advantages of the hybrid processes.…”

Sensing Technology (ST) plays a key role in Structural Health Monitoring (SHM) systems. ST focuses on developing sensors, sensory systems or smart materials that monitor a wide variety of materials properties aiming to create smart structures and smart materials, using Embedded Sensors (ESs), and allowing continuous and permanent measurements of the structural integrity. The integration of ESs is limited to the processing technology to embed the sensor due to its high-temperature sensitivity and the possibility of damage during its insertion into the structure. In addition, the technological process selection is dependent on the base material composition, either metallic or composite parts. The selection of smart sensors or the technology underlying them is fundamental to the monitoring mode. This paper presents a critical review of the fundaments and applications of sensing technologies for SHM employing ESs, focusing on the actual developments and innovation of these, as well as analysing the challenges that these technologies present, to build a path that allows a connected world through distributed measurement systems.

“…On the other hand, combining conventional manufacturing with the additive manufacturing process [15][16][17], which is also called the hybrid forming process, seems to be a reasonable method for complex mold and die forming [18]. The hardened surface region of molds and dies require high levels of hardness, which requires a significant martensite phase in microstructure.…”

The combination of additive manufacturing and conventional metal forming processes provides the possibility for improvements of forming efficiency and flexibility. Substrate preheating is an implementable technique to improve the interface adhesion properties of the hybrid forming method. The present experiment investigates the adhesion of additive manufactured 316 L steel on P20 and 1045 steel substrates under two substrate temperatures, and the geometrical characterization, interfacial microstructure and mechanical property of the hybrid specimens were compared. As a result, it was found that the ratio of deposition height to the width was reduced and the width was increased under substrate preheating. Tensile results show that the ultimate strength of 1045 and 316 L hybrid specimens was obviously increased, while the properties of hybrid specimens P20 and 316 L were similar, under different substrate temperature conditions. For the hybrid specimens with the metallurgically bonding characteristic, the tensile properties can reach the level of 316 L depositioned specimens fabricated by laser metal deposition (LMD). Furthermore, substrate preheating had little effect on the microstructure of the laser metal deposition zone, and significant influence on the microstructure of the heat affected zone, which was reflected in the difference of the hardness distribution.
