The present study aims to analyze the panorama of patents related to biodegradable polymers for filaments applied to 3D printing, focusing on the B33Y classification. The research was carried out in the Espacenet database, using the terms “Print” AND “Biodegradable”, “Polymer” AND “Filament”, associated with the technological domain of additive manufacturing. 23 patent families with protection were identified in Brazil between 2006 and 2026 The results show significant growth in filings from 2021 onwards, indicating a recent expansion of technological interest in sustainable materials for three-dimensional printing. There was a predominance of deposits in the United States of America (USA), Germany, France and Denmark, with companies focused on regenerative medicine, biomaterials and sustainable additive manufacturing standing out. The main IPC classifications focus on groups B33Y, A61L and A61F, related to 3D printing, biomaterials, implants and tissue engineering. The legal analysis showed a predominance of active and granted patents, indicating high strategic interest and market potential. It is concluded that 3D printing based on biodegradable polymers constitutes a strategic, interdisciplinary and expanding technological area, driven by the global demands of sustainability, personalized medicine and innovation in biomaterials.
