“…UAM was used by several authors to produce metal FGMs. [84][85][86] For instance, Kumar [84] studied the joining of different metallic foils using stainless steel, Al, and Cu foils. The foils were joined by ultrasonic welding using a machine that mechanically vibrates the welding head at 20 kHz.…”

Recent advances in multi-material 3D and 4D printing (time as the fourth dimension) show that the technology has the potential to extend the design space beyond complex geometries. The potential of these additive manufacturing (AM) technologies allows for functional inclusion in a low-cost single-step manufacturing process. Different composite materials and various AM technologies can be used and combined to create customized multi-functional objects to suit many needs. In this work, several types of 3D and 4D printing technologies are compared and the advantages and disadvantages of each technology are discussed. The various features and applications of 3D and 4D printing technologies used in the fabrication of multi-material objects are reviewed. Finally, new avenues for the development of multi-material 3D and 4D printed objects are proposed, which reflect the current deficiencies and future opportunities for inclusion by AM.

“…Smart material structures could be printed by embedding fibres, conductor, dielectric, and nano-fibres of NiTi shape memory alloy into a metal matrix [133]. Carbon fibres [134], fibre Bragg grating (FBG) [135], polymer-coated and uncoated optical fibres [136], metal-coated optical fibres [137], and NiTi shape memory alloy fibres [138,139] could be successfully embedded into Al matrix with sufficient bond strength in the welded interfaces of the metal foils while retaining their functionality.…”

Beamless Metal Additive Manufacturing

The propensity to manufacture functional and geometrically sophisticated parts from a wide range of metals provides the metal additive manufacturing (AM) processes superior advantages over traditional methods. The field of metal AM is currently dominated by beam-based technologies such as selective laser sintering (SLM) or electron beam melting (EBM) which have some limitations such as high production cost, residual stress and anisotropic mechanical properties induced by melting of metal powders followed by rapid solidification. So, there exist a significant gap between industrial production requirements and the qualities offered by well-established beam-based AM technologies. Therefore, beamless metal AM techniques (known as non-beam metal AM) have gained increasing attention in recent years as they have been found to be able to fill the gap and bring new possibilities. There exist a number of beamless processes with distinctively various characteristics that are either under development or already available on the market. Since this is a very promising field and there is currently no high-quality review on this topic yet, this paper aims to review the key beamless processes and their latest developments.

“…UAM has been used to fabricate soft materials, such as Al alloys [11,12], harder materials, such as copper [13][14][15], nickel [16], steel [17,18] and titanium [19][20][21], dissimilar materials, such as Al-Ti [21], Al-Cu [15], Al-steel [22], Al-NiTi [23,24], Al-MetPreg (a fibre-reinforced aluminium) [25][26][27] and Ni-steel [18] and metal matrix composite with embedded elements, such as SiC fibres [28,29], shape memory alloy fibres [30], dielectric materials (used in printed circuit board) [31], electronic circuitry [32], glass fibres and fibre optic sensors [33][34][35] and carbon fibres [36].…”

A review of microstructure evolution during ultrasonic additive manufacturing

Ultrasonic additive manufacturing (UAM) is a solid-state metal additive manufacturing process, with the combination of layer by layer ultrasonic seam welding and CNC machining. Due to the friction and deformation at the bonding interface, the ultrasonic softening effect and temperature generated, the microstructure of the substrate materials is evolving constantly. In this paper, in order to better understand the bonding mechanisms, the good practice and the capability of UAM, and the influence of different key process parameters on bonding quality, the microstructure evolution during UAM is reviewed in detail. Defects can be generated at the UAM bonding interface, but by choosing the right material combination and the right process parameters, defects can be reduced to minimum. Plastic deformation is very important for the bonding between layers during UAM, and plastic flow is important for redistribution of oxide layer, forming of mechanical interlocks, filling micro-valleys on the mating surface, and filling the gaps when embedding elements. UAM process can cause recrystallization and grain refinement at the welding interface and the intimate bulk materials around, and it will also gradually change the texture from rolling texture to shear texture. In the meantime, when further layers of materials are deposited on the top of the existing part, the microstructure will have some accumulative change. In order to reduce the defects number and increase the strength, sometimes, heat treatment needs to be carried out to the as-deposited parts, which will change the microstructure as well. Finally, the relevant research is summarised and the perspectives of further research are recommended.
