3D CAD and 3D printing-based product design: case study of an armchair

Digital design is an efficient way of implementing furniture concepts. Advanced tools for rendering have a considerable effect on increasing their visibility via the use of sophisticated software that simulates the final appearance of furniture using appropriate textures, colors and environment. Although color plays an important role in the product’s promotion, additional use of textures creates a more realistic appearance. The goal of this study was to develop an armchair using digital designing and physical prototyping. A variety of methodological and digital tools have been used to create a unique product, with effective application of 3D CAD and 3D printing technology in the design of an armchair. The present paper deals with the design of an armchair for children. Anthropometric shapes were used in the design process, thus digital sketches assisted in digitizing the armchair using an advanced Computer Aided Design (CAD) system. These models were enriched with colors and textures in order to convey the design concept, while providing a realistic view of the final solution. The prototype was built based on the CAD models created, in order to verify the incorporated specifications. Combining not only the effective geometry of the armchair but also its colorful appearance, a customized product for children was developed. Both the methodological and technological tools used supported the creative approach to the design of the armchair presented.
