EXPERIMENTS
Parametric Pine
Exploring parametric design with bio-material for additive manufacturing

How it started
During the first semester of 2025-2026, BESIGN - The Sustainable Design School had a partnership project with the Be-Lab. Here, the students were given the task to experiment with bio-material recipe creation, FDM printer hacking and potential products creation.
How it developed
The given role was to experiment with sustainable fabrication processes with a focus on FDM printing, exploring its compatibility with the partnership student's created bio-materials and parametric design. The material experimented with was that of a pine needle paste.
More precisely, the goal was to generate a custom G-Code architecture using Rhino's Grasshopper, which could then be adjusted and modified based on the desired geometry.

"This experience with the Be-Lab confirmed by interest for additive manufacturing and allowed me to discover and learn new things such as programming with Rhino and understanding material p
"Hello! I am Elizabeth Nazarova, from Geneva Switzerland. Recently, I have completed my Master’s Thesis on the use of Generative Design for Additive Manufacturing for sustainability and performance optimization. This experience left me motivated to pursue a career mixing design, engineering and sustainability, making the Be-Lab particularly attractive as an internship opportunity."

Processes and Challenges
Injection moulding
The first process explored was injection moulding. The intern ideated on mould designs, CAD modeled and printed the moulds with a filament based 3D printer.
The challenges faced with this process were linked to the material not being viscous enough to fill the mould or the component’s not capable of solidifying due to lack of airflow.
Manual extrusion
Next, inspired by pastry bags, the Intern thought of a manual extrusion mould in which an interchangeable cross-section front plate would bring the aspect of parametric design.
​
Here, the challenge was linked to the material collapsing upon its own weight and overflowing in the mould.
Additive manufacturing
Along with compression molding which the BESIGN students explored, 3D printing was the only process which brought results.This last step look the longest to achieve as it required extra steps such as using advanced softare (Grasshopper) for parametric geomertry designs, as well as the creation of custom printer nozzle trajectories (GCode) allowing for intricate shapes.
Though trial and error, the intern and the coach managed to print a successful cup with a swerved design. The challenges in this process where again linked to material collapsing on its own weight and lack of viscosity.
