Advancements in Sustainable Clean Green Manufacturing: 3D Printing with Bio-Polymers and Bio-Plastics

3D printing, sometimes referred to as "Additive Manufacturing," is a technique that a variety of raw materials to make 3D objects layer after layer. Due to their deterioration, plastic-based products pose a serious threat to the environment. Recycling is acknowledged as best way to handle waste, as well as new products can be produced with 3d printer. The 3 most broadly used 3D printing methods at the moment are DLP, SLA, and FDM. In addition, fibrils, gel, solutions, metal alloys, thermosets, and photo-sensitive resins are among most often utilized materials for 3D printing. Global interest in using natural and bioresorbable materials as substitutes for artificial materials has increased in the past ten years. Based on their origin, sustainable polymers can be broadly divided into two categories: synthetic and bio-degradable. Bio-polymer comes from biomass and microorganisms, while synthetic ones are produced through biotechnology and petrochemical processes. The production sectors play a critical role in GHG emission, account for about 25% of global pollution. The United Nations’ Sustainable Development Goals (SDGs) 9 and 11 are crucial because they address a number of ecological pollutions, issues, such as economic hardship, unfairness, global warming, tranquility, and justice. Sustainable production and consumption approaches are crucial to addressing these environmental impacts caused by Greenhouse Gas emission and waste deposition. Biopolymer-based 3D printing offers numerous benefits beyond just material properties. It allows for precise control over the composition and structure of printed objects. By selecting right biopolymers and optimizing printing processes manufactures can improve mechanical, thermal, and biological properties in the final products. Bioplastics and biopolymers also generate lower levels of greenhouse gases than regular plastics over their lifespan. The vital objective of this study is to create various bioplastic sources from natural materials that can serve as raw materials in various additive methods, transitioning from traditional plastics derived from fossil fuels to biopolymers extracted from nature.
