“…Additive manufacturing (AM) or 3D printing (3DP) is an emerging technology poised to revolutionize the way products are fabricated from plastics, metals, concrete, ceramics, composites, and many others. − Using one of the seven ASTM 52900 recognized types of AM, material is typically added in a layer-by-layer fashion exactly where needed to form the desired geometry developed by using 3D modeling software. It has long been recognized that the fusing of materials in AM-derived objects leads to an inherent mechanical inferiority in traditionally manufactured objects, the extent of which depends on the AM technique, processing parameters, material, and postprint processing steps.…”

Fused filament fabrication (FFF) is a 3D printing technique used to manufacture thermoplastic objects that offers users nearly unlimited design freedom compared with traditional subtractive and formative methodologies. The most significant barriers prohibiting its more widespread adoption are the reduced mechanical properties compared to injection or compressionmolded counterparts and the large degree of mechanical anisotropy due to the layer-by-layer additive process, where strength between layers is developed through the reptation and entanglement of polymer chains. Herein, a highly cross-linked covalent adaptable network (CAN) based on the Diels−Alder reaction between furan and maleimide functionalities is blended with flexible and tough polycaprolactone (PCL) to afford a dynamic semi-interpenetrating polymer network (semi-IPN) that can be spooled for use on an unmodified, commercially available desktop FFF 3D printer. By leveraging the thermoreversible nature of the Diels−Alder adducts, strong covalent bonds can form across the interfaces between deposited tracks. Tensile testing is performed on specimens fabricated using 0 and 90°raster angles, causing stress to be transferred either along the tracks or across the interlayer welds, respectively. The semi-IPN exhibits a degree of mechanical anisotropy of 11% without requiring specialized hardware or postprint processing steps, a marked improvement over about 60% in the typical polylactic acid used in FFF. The addition of the PCL makes the toughness of the blend 100× that of pure CAN, and the 3D-printed objects do not contain void space between tracks, making them fully dense.

“…For this reason, many science groups have tried to develop AM techniques for producing new ceramic parts for different applications and new requirements. Therefore, some researchers reported review papers with developing viewpoints like Fidan et al 6 and Popov et al 7 Also, other researchers tried to review advances, challenges, and outlook of AM parts with the ceramic viewpoints such as Dadkhah et al, 8 Gupta et al , 9 Wang et al , 10 and He et al 11 The carbide-based ceramics are one of the interesting groups of ceramics, which have special properties like corrosion, oxidation, and wear resistance, high stability in high temperatures, and excellent hardness properties. Having these features causes these materials to be proper for use in wear-resistance coatings, machining tools, corrosion-resistance materials, milling tools, and cutting tools.…”

Fabricating and introducing new materials with new features is one of the most important goals for many scientific groups. Today, additive manufacturing (AM) is known as one of the new production methods, which can create an excellent opportunity for achieving this goal. As one of the ongoing production processes, the laser AM (LAM) methods have the proper capacity for producing new advanced materials like carbide, nitride, and boride‐based materials. Hence, this work aims to review carbide‐based materials produced by LAM techniques with the composite viewpoint. These materials can act as a matrix, reinforcement, or tertiary component in advanced composites. With this viewpoint, these composite materials were introduced in eight separate sections, which are tungsten carbide, titanium carbide, silicon carbide, niobium carbide, chrome carbide, vanadium carbide, and boron carbide, as well as high entropy alloy composites.

“…Today, PCBs can be produced not only in the traditional ways, such as layering, photolithography, drilling, and plating, but with recent advances in 3D printing technologies, they can also be produced additively [ 2 , 3 , 4 ]. Additive manufacturing has the potential to transform electronic component fabrication into a more flexible and customizable manufacturing process, surpassing the limitations of planar designs [ 5 , 6 , 7 , 8 ]. Other benefits of the additive manufacturing of electronic components include the efficient use of material resources, waste reduction, and the ability to produce specialized and personalized products on demand.…”

“…Potential applications could include the ability to 3D print electronics during space missions [ 10 ]. One example of inkjet additive manufacturing technology is the DragonFly LDM electronic sub-assembly technology, which enables the serial production of state-of-the-art electronic PCBs in laboratory conditions by using simultaneous deposition for conductive and dielectric ink [ 3 , 5 , 6 ]. The additional benefit of designing and manufacturing electronic devices using in-house resources is that, in this way, the risks associated with designing and manufacturing products in external, third-party environments are avoided: this protects against the possible leakage of product technological information, the copying of devices, or the introduction of hidden defects during manufacturing.…”

Multilayer printed circuit boards (PCBs) can be produced not only in the traditional way but also additively. Both traditional and additive manufacturing can lead to invisible defects in the internal structure of the electronic component, eventually leading to the spontaneous failure of the device. No matter what kind of technology is used for the production of PCBs, when they are used in important structures, quality control is important to ensure the reliability of the component. The nondestructive testing (NDT) of the structure of manufactured electronic components can help ensure the quality of devices. Investigations of possible changes in the structure of the product can help identify the causes of defects. Different types of manufacturing technologies can lead to diverse types of possible defects. Therefore, employing several nondestructive inspection techniques could be preferable for the inspection of electronic components. In this article, we present a comparison of various NDT techniques for the evaluation of the quality of PCBs produced using traditional and additive manufacturing technologies. The methodology for investigating the internal structure of PCBs is based on several of the most reliable and widely used technologies, namely, acoustic microscopy, active thermography, and radiography. All of the technologies investigated have their advantages and disadvantages, so if high-reliability products are to be produced, it would be advantageous to carry out tests using multiple technologies in order to detect the various types of defects and determine their parameters.
