This chapter has mostly examined how AM may help sustainability from various aspects of a product life cycle perspective. At this stage of the product life cycle, AM is a novel manufacturing process that has immediate impact. As a result of this research, it can be shown that the product’s life cycle is starting to profit from its environmental impact. Several early benefits are shown in this work, with the adoption and diffusion rates varying depending on the stage at which they were implemented. As a replacement for more conventional methods, additive manufacturing may also be used to produce customized small quantities or one-off objects. Increasing numbers of firms are embracing the technology or using service bureau solutions as a result of technical and commercial evidence of these advantages. For some companies, AM will be a direct replacement for their current manufacturing processes, while for others, it will serve as a complement or a vehicle to enter new markets. Second, AM offers a great deal of freedom in terms of design. It is possible to produce and save digital blueprints for additive manufacturing, enabling the fabrication of replacement parts on demand when repairs are needed. When modular design is paired with repair, remanufacturing, and refurbishment procedures, it is possible to extend and improve the lifespan of a product. The life cycle perspective of additive manufacturing and sustainable manufacturing on metal is suggested in a study (Peng et al., 2018), shown in Figure 8.7.
Hybrid Energy Systems for Vehicle Industry
Published in Yatish T. Shah, Hybrid Energy Systems, 2021
Modular design allows a smaller footprint and is therefore highly flexible during installation and also allows for future power upgrades. The compact design also means higher power density of the equipment, ensuring the conversion of electricity in a more efficient, secured, and reliable manner. GE’s SFC allows several loads, meaning several ships can be charged at the same time. Each converter can hold an overload of 150% for a short period, leaving enough time for the automatic coupling of a supplementary SFC. This means that when a new ship is charged, the immediate increased load will not disturb other ships that are already charging, allowing the smooth operation without load impact. This project has the possibility of seamless future expansion. One can adapt and optimize the Harmonic Filter upstream to the converter frequency according to the grid evolution, allowing easy implementation of extra power capacity if needed in the future, all while keeping the benefit of a simple installation. A special storage device and smart control are also being developed to provide reliable energy supply when microcuts occur, ensuring continuation of the power supply. GE’s smart management during events of microcuts is proven to be able to avoid tripping clients’ installations several times per year [27,28].

The main idea of modular design is to divide complex system into a set of distinct components such as fixed stage, flexure component, intermediate stage and the motion stage which can be developed independently and assembled together. The micromotion stage consists of six compliant prismatic joints (P-joints). Two symmetrical single leaf flexure compliant prismatic joints (SCP) and identical double-leaf flexure compliant prismatic joints (DCP) as shown in Figure 1. Each limb consists of one SCP joints and two DCP joints in serial connection. Parasitic motions can be eliminated due to double-layer leaf spring flexures as shown in Figure 2. The symmetric layout with 2PP (P-prismatic joint) configurations are adopted. The geometrical parameters are given in Table 1.
Modularisation of system architecture to improve system recoverability: a unique application of design structure matrix
Published in Journal of Engineering Design, 2021

In order to establish and/or improve the recoverability characteristic for a system, providing a modular design for the architecture of the system is one of the most important considerations in the literature (Pimmler and Eppinger 1994; Gershenson, Prasad, and Zhang 2003; Ulrich and Eppinger 2008; Efatmaneshnik, Shoval, and Qiao 2018). Generally, Modular design for a system (i.e. modularity in system architecture) is a design approach that subdivides a system into smaller unites/parts that are commonly called modules, which can be independently created, modified, exchanged, or replaced with other modules or between different systems (Gershenson, Prasad, and Zhang 2003).

Considering manufacturing in ideal conditions, the modular design achieves the greatest cost reduction, since lower operating and labor costs are accomplished due to a shorter design schedule, efficient use of material and less field staff. For projects with several units, there is a greater capital efficiency by designing only once and reusing the project (Shah 2020). The construction of an external module does not interrupt or end preexisting operations, allowing a plant to continue operating during its expansion.
