“…Though this strategy seems to eliminate using the part material as support, it instead requires the repeated heating and cooling of water to induce the necessary phase change, which may be less energy efficient. Multi-axis or robotic additive manufacturing processes were also investigated by [103][104][105]. However, these techniques may require high cost at the beginning and the extra complexity within the manufacturing process will likely render any support reduction strategies highly specific to the process in question.…”

Additive manufacturing (AM) has developed rapidly since its inception in the 1980s. AM is perceived as an environmentally friendly and sustainable technology and has already gained a lot of attention globally. The potential freedom of design offered by AM is, however, often limited when printing complex geometries due to an inability to support the stresses inherent within the manufacturing process. Additional support structures are often needed, which leads to material, time and energy waste. Research in support structures is, therefore, of great importance for the future and further improvement of additive manufacturing. This paper aims to review the varied research that has been performed in the area of support structures. Fifty-seven publications regarding support structure optimization are selected and categorized into six groups for discussion. A framework is established in which future research into support structures can be pursued and standardized. By providing a comprehensive review and discussion on support structures, AM can be further improved and developed in terms of support waste in the future, thus, making AM a more sustainable technology.

“…UAM can be used to weld dissimilar metals [11][12][13][14] and to embed various materials through the additive and subtractive processes. Previous efforts have demonstrated how ceramic neutron absorbers can be embedded in aluminum alloys for control plate applications in research reactors [15]. The same process can be used to embed sensors within parts fabricated from UAM or near the surface of components manufactured using other processes, as described in the next section.…”

“…High Flux Isotope Reactor (HFIR) control elements are large, thin cylindrical plates that are conventionally manufactured through powder metallurgy and explosive forming. Thin tolerances (e.g., small cladding thickness) and rigorous requirements for these components have driven activities in ultrasonic additive manufacturing ( Figure 2) with the objective of reducing cost for making conforming reactor components [9].…”
