Smart & Biomaterials for Innovative Biomedical Products Fabricated by Additive Technologies

The chapter on smart and biomaterials for innovative biomedical products fabricated by additive technologies provides an overview of the materials and principles underlying modern biomedical engineering. It discusses the classification, properties, and functionalization of key biomaterials—polymers, metals, and ceramics—used in the design and manufacturing of medical devices and implants. Special attention is given to surface modification and characterization methods that enhance biocompatibility, mechanical performance, and biological interactions.

The chapter further examines the emergence of smart materials capable of responding to external stimuli such as temperature, pH, electric, or magnetic fields, including shape-memory polymers, piezoelectric composites, and self-healing systems. These materials are analyzed in the context of additive manufacturing, highlighting their integration into 3D printing processes, the challenges of multi-material fabrication, and the opportunities for creating adaptive, functional biomedical products.

Through selected case studies, the text illustrates practical implementations of these materials in bioprinting, tissue engineering, and smart textiles for healthcare applications. Emphasis is placed on the role of material innovation in enabling personalized and intelligent biomedical devices that combine mechanical performance, biological compatibility, and responsiveness to physiological environments.
