Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.â United Nations 1987, Our Common Future
1.1 Introduction
Currently, there is consensus among governments, corporations, and public opinions in developing and industrialized countries worldwide on the necessity to reduce pollution and waste, and efficiently use the natural resources, in order to protect health and the natural environment, and achieve and maintain a sustainable standard of living and economic development. A material is sustainable if it is derived from renewable feedstocks, and can be recycled and disposed of in ways harmless to the environment. Sustainable polymers (SPs) are polymers derived from renewable feedstocks, such as plants, animals, and microorganisms. Their utilization enables to achieve the above objectives, and is growing, thanks to the development of cost-effective industrial production routes, consumersâ demand for eco-friendly products, and pro-environment policies and legislations at national and local level, and international agreements that have been implemented for decades, among other factors. SPs also critically contribute to transitioning from the current economy towards the circular economy that is an economic model (described later in this chapter) minimizing the use of natural resources and energy, and generation of waste. Furthermore, when SPs are processed through specific fabrication methods termed additive manufacturing (AM) or 3D printing (simply referred to as printing hereafter), SPs reduce feedstock waste, and at the same time are turned into innovative products with novel and advanced properties and functionalities.
Although the figures may vary depending on the information sources, experts agree that the global AM market will significantly grow, as it has steadily and rapidly done in the last 30 years. The global AM market (including printers, materials, software, and services) is expected to grow from USD 8.4 billion in 2018 to USD 36.6 billion by 2027 at an impressive CAGR of 17.7% (Report Buyer 2019). According to another source, the AM global market will steadily increase from USD 9.3 billion in 2018 to USD 41.6 billion in 2027 (Sher 2018). A 3D or AM printer (referred to as printer hereafter) is a machine fabricating a physical object by adding material selectively (that is in selected locations) and layer upon layer to reproduce a 3D digital model.
Currently, SPs for AM are preferred for non-functional, do-it-yourself items instead of engineering and load-bearing applications, although reinforced SPs have been chosen for architectural-size load-bearing structures, such as the Leaf Bridge (Relander-Koivisto 2018) made of materials supplied by UPM Formi 3D (Finland), and the pavilion components designed by SHoP Architects (USA) for Design Miami 2016 event (Cascone 2016). If SPs for AM are to transition from household and display items to engineering and functional components, they have to combine a competitive price and adequate and consistent values of physical and mechanical (static, dynamic, long-term, above and below room temperature, etc.) properties under various more or less demanding service conditions associated with load-bearing applications.
This book describes a multitude of experimental and commercial SPs for AM, but only those that meet a combination of the following requirements will be commercially successful: possessing a ratio performance/cost competitive with or superior to existing feedstocks, filling a specific need currently unfilled,...
