Towards Bio-Mimetic 3D Printable Human Anatomies

3D printing, or additive manufacturing, has revolutionized various industries, particularly in healthcare where it facilitates the creation of personalized medical solutions. However, achieving biomimicry, especially in anatomical models, remains a challenge due to the mismatch in mechanical properties between synthetic polymers and biological tissues. This study aims to bridge this gap by reviewing the mechanical properties of human anatomical tissues and investigating analogous properties in 3D-printable polymers. Using a combination of literature review and experimental methods, the study focuses on anatomical structures such as bones, skin, and cartilage. Four base polymers with distinct mechanical characteristics are blended to create nine different polymer compounds, which are then subjected to compression and tensile tests. Results reveal varying mechanical properties across the polymer blends, with some exhibiting promising biomimetic potential.
