Abstract

This study focuses on the design and development of a three-dimensional (3D) printed furniture joint that is versatile and applicable across various furniture designs and styles, addressing the inherent limitations of traditional furniture joints. Conventional methods often rely on custom-made joints, which are not only time-intensive but also costly to produce, modify, or repair. To overcome these challenges, this research aims to create a furniture joint optimized for both strength and functionality through the application of topology optimization analysis. A comprehensive methodology was employed, beginning with a questionnaire survey to identify user needs and establish product design specifications. Following this, the design concept was developed and evaluated to finalize the joint design. Based on the selected design, a topology optimization analysis was performed to enhance its structural efficiency. The analysis revealed a 45.6% reduction in mass compared to the original joint design. While the structural analysis indicated that the optimized joint experienced slightly higher stress levels than the original design, the maximum stress values remained well below the yield strength of ABS material. This finding confirms the optimized joint’s structural integrity and low likelihood of functional failure. The optimized furniture joint, manufactured using 3D printing, demonstrated excellent compatibility and fit with furniture components, including tabletops and legs. This adaptability enables the production of a wide range of furniture designs, including coffee tables, side tables, bookshelves, shoe racks, and honeycomb bookshelves. Furthermore, integrating 3D printing and topology optimization offers several advantages, including reduced material waste, shorter production times, and a more environmentally sustainable approach to furniture manufacturing.
