Design and Fused Deposition Modeling of Furniture Risers Using Polyamide Filament

Abstract

Fused deposition modeling (FDM) 3D printing technology was used to customize furniture risers to match furniture dimensions and children’s body sizes. The goal was to achieve a rapid, safe, and sustainable height adjustment solution for children’s furniture. Polyamide (PA) filament was chosen as the printing material. Compression tests were performed to investigate the properties of the 3D-printed PA models under varying process parameters, including layer thickness, infill density, and heated bed temperature. Experiments showed that as the layer thickness decreased, the infill density and the heated bed temperature increased. The compressive strength and compressive modulus of the PA model gradually increased, and the compressive properties improved. The optimized process parameters for compressive properties were: layer thickness (0.1 mm), infill density (90%), and heated bed temperature (90 °C). Using these parameters, this study completed the fabrication of furniture risers via FDM 3D printing. The 3D-printed furniture risers exhibited excellent compressive strength and surface finish, and they allowed for quick height adjustment to accommodate children’s varying body sizes. Moreover, the 3D printing approach itself was cost-effective and highly efficient. These benefits collectively highlight the application value of 3D printing for customized furniture components in promoting children’s healthy growth and saving resources.
