Polyetheretherketone (PEEK) is a top-level polymer combining cutting-edge engineering with new medicine. PEEK is noted for its superior mechanical properties, thermal stability (Tg = 143°C, Tm ≈ 343°C), and chemical resistance against corrosive agents, and its role in green manufacturing, setting new standards in several fields, from aerospace to medicine. This article examines new methods of producing PEEK, more crosslinks, and nucleophilic polycondensation, which augmented its thermal stability and strength. Fused filament fabrication (FFF) and digital light processing (DLP) are new methods of producing tailor-made implants for patients and lightweight aircraft components, illustrating how versatile PEEK is in a 3D printing process. PEEK (polyether ether ketone) is beneficial in biomedical applications because its stiffness matches that of human bone (3–4 GPa), reducing stress shielding in implants. While it is bioinert, recent surface treatments like plasma grafting and hydroxyapatite coating improve its integration with bone. Outside of the medical field, PEEK is a long-lasting lithium-ion battery separator and is suitable for water applications due to its resistance to seawater wear. Microfluidic systems that take advantage of PEEK's inert qualities and radiation-shielded composites like boron carbide-PEEK for nuclear applications are further developments. Despite its versatility, PEEK has issues with recycling, durability in the face of intense radiation, and standardization in 3D-printed medical devices. Interdisciplinary cooperation is essential for developing PEEK in green manufacturing and technology in order to overcome these challenges.
