3. Cross-cutting issues

 Due to the systemic nature of the phenomenon, there are overlaps between the six topics identified. The issues at these intersections are explored in this section. In an optimistic scenario, transitioning to 3DP will lead to many more benefits for sustainability as many of 3DP's characteristics align with sustainability and circularity concepts (Ford and Despeisse, 2016). Early concepts of circularity were developed in the late 1980s and have progressively made their way into companies' strategic resource management. These concepts adopted an industry perspective on sustainability, often disregarding the role of individuals and culture in achieving more efficient use of natural resources and closed-loop circulation of materials. The concept of industrial metabolism (Frosch and Gallopoulos, 1989; Ayres, 1989), now widely known as industrial ecology (Graedel and Allenby, 2002), emerged in response to resource scarcity and the consequent increase in material cost. A key principle of industrial ecology considers sources and sinks of natural resources, and promotes a regenerative use of resources where consumption should not exceed regeneration rate. Therefore, increasing manufacturing efficiency through process efficiency and recycling is key. Reducing material waste in process and recycling are both clear advantages with most 3DP technologies (Royal Academy of Engineering, 2013). Industrial ecology is strongly based on a biological analogy where industrial systems are compared to natural ecosystems (Frosch and Gallopoulos, 1989; Graedel and Allenby, 2002). In such ecosystems, synergies occur naturally as individual organism maximises their own benefits by consuming the waste produced by another. Thus wastes and resources flow in a circular manner between the different ecosystem components with renewable energy powering those cycles. Industrial ecology encourages the formation of such synergies in between companies across industrial sectors, systematically seeing waste seen as an abundant, local and free resource. Researchers have explored ways in which 3DP could enable such synergies to be formed by looking at how locally recycled materials could find their way as inputs to 3DP processes (Kreiger et al., 2014; Garmulewicz et al., 2016). The role of 3DP in enabling recycling was examined in Sections 2.2 and 2.4.
