3D Printed Connection System for Bamboo Structure Construction

The construction industry is increasingly adopting sustainable solutions, with bamboo emerging as a resilient and eco-friendly material. However, challenges persist in bamboo construction, particularly in developing effective techniques for joining bamboo poles. This study aims to evaluate the structural performance and stress distribution of 3D-printed connectors for bamboo structures. By leveraging 3D printing technology, this research seeks to improve bamboo construction methods addressing its non-uniformity, streamlining design and production, and the potential use of bio-based material. Performance evaluations were conducted through software simulations and digital image correlation (DIC) to assess the mechanical behavior of the connectors and showed 1.561mm and 1.80mm displacement, respectively. The analysis identified areas requiring refinement to enhance load-bearing capacity and optimize stress distribution. The findings suggest that the connectors are explored using different materials, geometry, and even more advanced and efficient design of structures. Furthermore, this study provides practical insights into the viability and sustainability of the integration of 3D printing technology into bamboo construction practices.
