HC3DP
[. . .Hollow-Core 3D Printing. . .]
This one-week project focused on exploring the Hollow-Core 3D Printing (HC3DP) technique, where the investigation centered on the intrinsic characteristics of light refraction through transparent structures, the development of an interlocking system, and an in-depth study of the fabrication setup to optimize ideal printing parameters
Hollow-Core 3D Printing (HC3DP) is an innovative material extrusion (ME) 3D printing technique that introduces tubular, hollow beads instead of traditional solid ones. This approach addresses key challenges in large-scale 3D printing, such as prolonged cooling times, high material consumption, and environmental impact. By enabling faster production speeds, reduced material usage, and improved thermal efficiency, HC3DP pushes the boundaries of polymer-based 3D printing into architectural and construction-scale applications. Developed as part of interdisciplinary research at NCCR Digital Fabrication (DFAB), ETH Zurich, this method offers a sustainable and scalable solution for fabricating complex, highly insulating, and lightweight components.
