Abstract

This study aims to design and fabricate a prototype of massage chair made of corrugated cardboard materials and evaluate its structural strength. It could be a pioneering study as no one had manifested or discussed it before. The prototype is currently made with dimensions of approximately 60 ´ 50 ´ 100 cm, consisting of 6 cardboard components, affords a reflexology sensation from solid rubber balls, and provides reclinable features at the backrest and footrest. The most prominent benefit of this cardboard massage chair compared to the commercialized ones is environmentally friendly and lightweight products. Moreover, the constructed component can be disassembled and folded, making it a portable massage chair. From the strength evaluation, the cardboard massage chair can still endure a load of 50 kg to the prototype’s seat, backrest, and footrest. However, multi loading directions (e.g., vertical, longitudinal, lateral), stress concentration, and fluctuating person weight would generate tremendous stress and lead to a more substantial possibility of damage and failures on the cardboard after several testing cycles. Therefore, further improvement processes should be investigated to develop an optimized version of cardboard massage chair in the future.

Abstract

Additive manufacturing or 3D printing is a rapidly moving fabrication technology with many usages in various fields. One of the methods used in 3D printing is Fused Deposition Modeling (FDM), where polylactic acid (PLA) filament is melted and deposited layer by layer to form the desired parts. This study explored the impact of annealing on the mechanical properties of 3D printed PLA specimens. Tensile specimens were produced using FDM following ASTM D638 standards. The specimens were annealed at 95°C and 145°C for 30, 60, and 120 minutes. Two untreated specimens served as benchmarks. Tensile tests were conducted on all specimens to evaluate their mechanical properties. The most optimal result was achieved with annealing at 95°C for 30 minutes, producing Young’s modulus of 3.3 GPA and the highest ultimate tensile strength (UTS) of 38.9 MPa. Other parameters resulted in lower properties compared to the untreated specimens.
