The three-dimensional form of a product is a key element in the development of a brand identity through the computational design methodology. Brand identity has an in-depth relationship with the object’s shape and product assembliness. In traditional mass production design methodologies, designers encode specific parameters into design rules that aren’t used by end-users to customize their own products. The “Do-It-Yourself (DIY)” process enable users to express themselves through the design thinking approach. Self-design is a form of co-creation between designer's knowledge and customer's skills according to the branded product design parameters. Under this statement, the object’s geometrical form and the product assembliness are fundamental principles in the promotion of a holistic design identity to the industry and to the market. The current paper combines the use of computational design with specific parameters of DIY bookcase/desk (i.e., height, length, width, number of shelves, etc.) in order to develop a generative design system for the mass customization of DIY bookcases/desks alternatives. The results from the end-user application offer, automatically alternatives 3D models under the "Do-It-Yourself" brand umbrella.

Nowadays, the circular economy model is basically built on the efficient use of resources and the maximization of the product’s lifetime as long as possible, by recovering, reusing and recycling existing materials and products. Comparing circular economy with the new trend of customized products, there is an opportunity for the production of personalized products with less associated environmental costs. As a key factor can be considered the 3D printing technology, which is already widely accessible, offering customisable possibilities without expensive tooling based on individual specifications. Furthermore, the opportunity for recycling and degradation of different plastic materials and the creation of a filament for 3D printers has large impact on the product life cycle. The aim of this study is to highlight the management of recyclable plastic by creating new customized products. Souvenir industry has been chosen as a representative example which covers a big number of different products offering simultaneously a mass customized character.

This paper explores the creation of architectural structures through parametric design tools. The proposed methodology presents an alternative framework of using digital tools for the product design development from the design thinking point of view. The main core of the suggested design process includes a great number of theoretical issues from design identity, design language and architectural design areas. As a result, designers can develop constructions for public spaces that are based on innovative morphologies by using new digital design techniques such as computational design (Rhino3D and Grasshopper). The development of an architectural structure that aims to bring greenery into the city and increase the rest and action spaces is presented. A valuable aspect of this exploration is in positioning the proposed design framework inside - to aid in the creative process and better leverage downstream outcomes. The final steps of the proposed methodology include the production of the final architectural structure through rapid prototyping, laser cutting and engraving techniques.
