Abstract: As an emerging and transformative technology in the culinary and food manufacturing sectors, the development of 3D printed food heavily depends on the continuous optimization of material systems and the rigorous assurance of chemical safety. This paper comprehensively analyzes the diverse types and functional characteristics of 3D printed food materials, encompassing basic nutritional ingredients (such as cereals, high-quality proteins, and various fruits and vegetables), essential food additives (including thickeners, stabilizers, and gelling agents), and specialized printing auxiliary materials (such as supporting structures and binding agents). Building upon this foundational classification, the review systematically discusses the full-chain risk associated with chemical safety assessment. This involves a detailed examination of natural toxins and pesticide residues in basic agricultural ingredients, the strict regulatory compliance of synthetic additives, the potential residue migration from auxiliary materials, complex chemical changes occurring during thermal or mechanical processing, and advanced finished product testing methodologies. Furthermore, it elaborates on strategic approaches for innovative formulation development. These strategies focus on meticulous ingredient screening, precise additive adjustment, auxiliary material improvement, and enhanced processing adaptability, ultimately aiming to perfectly balance printing performance, structural fidelity, and consumer safety. The comprehensive study demonstrates that implementing full-chain risk assessment protocols and targeted formulation optimization are absolutely critical to ensuring the commercial viability and sustainable development of 3D printed food technology in the modern food industry.
