Rhino - Grasshopper - HAL Robotics - Robot Studio - ABB Robot - 3D Printing 
"Parametric Biomimicry" explores the fascinating geometry of spiral seashells, translating these natural forms into intricate 3D models through advanced computational design and robotic fabrication techniques. This research, conducted under the supervision of​​​​​​​ Professor Negar Kalantar at Autodesk Technology Center (Pier 9), bridges the gap between digital and physical realms, utilizing the natural layering processes of mollusks to push the boundaries of architectural design and 3D printing.​​​
Research Journey:
1.Exploring Seashell Geometry:
The project began with an in-depth study of the intricate geometry of spiral seashells. Using computational design tools in Grasshopper, I developed detailed 3D models that captured the complexity and elegance of these natural forms.
The business of building the shell falls to the mollusk's mantle. This thin, soft organ secretes layer on layer of a substance rich in calcium carbonate at the opening, or aperture, of the shell. It only needs to follow three basic rules to form the characteristic spiral seen in the shells of snails and their relatives, the gastropods. (Moulton, D. E., Goriely, A., Chirat, R., & Christie Design, B. (2018). How seashells take shape. Scientific American, 318(4), 68-75.)

Expand: 
By uniformly depositing more material than it did on the previous pass, the mollusk creates a slightly larger opening at each iteration.
Rotate:
By depositing slightly more material on one side of the aperture, the mollusk achieves a full rotation of that aperture, building a doughnut shape, or torus, from an initial circle
Twist:
The mollusk rotates the points of deposition. by adding this step, the result is what mathematicians describe as a nonplanar, helicospiral shell.

2.Robotic Light Visualization:
To enhance the precision and visual impact of the fabrication process, I designed a compact LED spotlight tool mounted on the robot's head. This tool traced the robot's movements through space, and long-exposure photography captured the resulting luminous patterns, creating a mesmerizing "ghost" of the robot's trajectory.
The role of different parameters such as twist, expansion rate, division, and turns, and how the effect of twist changes the luminous seashell.
3.Collaborative Robotic 3D Printing:
For the final fabrication, I employed a static printing nozzle with a moving bed, managed by a 6-axis robotic arm. This setup allowed for the replication of the precise geometry of the spiral seashells, showcasing the potential of non-planar 3D printing. The result was a series of complex, scaffold-free structures that demonstrate both efficiency and aesthetic appeal.
Academic Collaboration and Presentation:

This project was carried out in collaboration with Professor Negar Kalantar at Autodesk Technology Center (Pier 9) and was presented to the Autodesk and CCA communities.
I also had the opportunity to discuss the research with Dr. Alain Goriely, Mathematician from Oxford University, whose research paper laid the foundation of this project.
