AI Technical Summary
Existing methods for manufacturing 3D printed structures for hard tissue regeneration face challenges such as the need for supports, which increase production time and cost, and the use of chemical crosslinking agents that pose health risks.
A method for manufacturing a self-supporting organic-inorganic composite 3D printed structure using a coagulation bath containing collagen, inorganic materials, ethanol, and a pH adjuster to induce collagen hardening, allowing for the formation of structures without supports and avoiding chemical crosslinking agents.
The method enables the production of self-supporting structures with overhang features, reducing production time and costs, and eliminates the risks associated with chemical crosslinking agents, while maintaining excellent bone differentiation gene expression.
