The innovations in biomimicry and 3D printing are impressive and straightforward. Substantial strides have been achieved in five principal domains: manufacturing, military/aerospace, construction, healthcare, and environmental sustainability. Numerous sectors leveraging additive manufacturing (AM) are taking cues from nature. In essence, AM and biomimicry are being used to create more robust, lightweight materials, design efficient structures, reduce environmental waste, update construction methods, transform production facilities, and propel medical advancements. Now, let's discuss what biomimicry entails and the specific role of 3D printing.
What is Biomimicry
Biomimicry, also known as biomimetics, combines "bio," meaning nature, and "mimicry," meaning imitation. These words describe learning from nature and integrating its structures or solutions into human creations. This concept has been demonstrated before with examples like the Fibonacci sequence, the golden ratio, or airplane wings that mimic birds.
How 3D Printing Advances Biomimicry
biomimicry and 3D printing are increasingly being integrated, especially with the development of more natural materials and the introduction of new patterns or structures into part designs. This synergy allows 3D printing to replicate natural forms effectively. Moreover, this approach is relevant across various industries, including architecture, consumer goods, and fashion.
An example of this is a 3D-printed biomimetic shoe created using SLS technology and flexible TPE, a material known for its comfort and flexibility. This innovative design, depicted below, evokes images of roots and life.
3D Printing with Lattice Designs
The lattice structure, frequently employed in 3D printing, draws inspiration from nature. This design, reminiscent of a honeycomb, is prevalent in numerous products and offers cushioning properties when utilized in various applications. 3D printed using Carbon technology and a 40% bio-based material. This structure is also commonly seen in items such as lattice, bicycle sheets, and backpacks with shock-absorbing mesh, enhancing comfort for users during activities like hiking. Besides improving comfort, this approach minimizes material usage and optimizes the overall weight of objects.
