Hollow Core 3D Printing Exploration



This project centers on robotic fabrication using hollow-core, air-extruded PETG material to create a series of lamps utilizing an advanced 3D printing method known as Hollow Core 3D Printing. The design team explored various non-planar geometries, leveraging parametric and computational tools alongside Blender for caustics simulations. The print path was scripted in Python to slice the lamp designs and control layer height, speed, and air pressure for each frame. Grasshopper and GHPython were integrated with the Python scripts to visualize and manage print path parameters, which were then exported as JSON files for robotic execution. Extrusion parameters were regulated using Arduino software. The process faced several challenges, including the need for precise robotic arm movements to achieve high-resolution prints, maintaining consistent material flow due to PETG’s specific viscosity and temperature requirements, and ensuring proper layer adhesion to avoid defects.
