Lightweight design of seat based on parametric modeling and 3D printing
With the development of the economy and societal civilization,the demand for comfort in furniture has grown significantly.Consumers today not only seek functional furniture but also prioritize comfort,aesthetics,and overall well-being.The increasing emphasis on personalized and emotional needs in the design of seat products reflects a broader trend in consumer expectations.In order to better meet the personalized and emotional needs of modem consumers for seating products and enable lightweight structures of the chairs,based on the concept of parametric design,the integrated molded Pantone chair was selected as the research object for design and study.The use of parametric design,particularly for the integrated molded Pantone chair,provides a versatile and efficient approach.This allows for easy customization based on individual preferences,ergonomic considerations,and aesthetic choices.A parametric modeling method was proposed,and three parametric design schemes for porous structures were completed with the help of the 3D modeling software Rhino and the parametric plugin Grasshopper.To further validate the reliability of the design optimization in practical applications,one of the proposals was selected for stress analysis,strain analysis,and fatigue analysis through the ANSYS software.The analysis results revealed that the proposed scheme performed stably under various conditions,which demonstrated its feasibility in practical applications.Finally,the 3D model from finite element analysis was presented through 3D printing technology,making personalized seating possible and satisfying consumers'personalized and emotional needs.In this research,with parametric and 3D printing technology and through the applied parametric modeling method,the design and study of Pantone chair was conducted,and the feasibility of this technical approach was verified through finite element analysis.This approach enabled lightweight seat structures,product differentiation,and different personalized and emotional experiences for customers.This study can serve as a reference for the digital design and manufacturing development in the furniture industry.
