Three-dimensional (3D) printing technology is capable of creating highly complex, customizable objects, offering unique advantages for various biomedical applications through methods such as inkjet-based, extrusion-based, and light-assisted techniques. This study focuses on using direct ink writing for additive manufacturing to print antibacterial wound dressings, addressing a critical gap in the current wound care market. The management of chronic and acute wounds presents significant challenges facing human health and overall wellness. Current wound dressing fails to meet patients needs in terms of high adhesion, poor gas exchange, low moisture retention, and the use of systemic and synthetic antibiotics. Additionally, the presence of unused agricultural waste and weak waste management increase greenhouse gas emissions, thus contributing to global warming. To address these issues, we utilized agricultural waste, specifically sugarcane bagasse, to create biopolymer 3D printing ink for wound dressings. We extracted cellulose from sugarcane bagasse and antibacterial bioactive compounds from plant extracts. The synthesized ink was then printed and post treated to enhance mechanical properties. We evaluated the cytotoxicity, antibacterial activity, and morphological structure of the patches using scanning electron microscopy.
