In informal urban settlements, there is an abundance of plastic waste material, which creates a range of health and environment-related problems. At the same time, there is a lack of locally produced products to improve the conditions for basic needs such as water and hygiene. As a means to connect these two challenges, we propose a distinctive solution in this paper: Do-it-Yourself (DIY) workspaces run by local entrepreneurs that transform plastic waste into valuable water and sanitation products. Our focus area during this project was the Korail slum in Dhaka. With the support of the Capability Driven Design (CDD) method, that aids design teams to systematically and comprehensively explore user contexts, we conducted an intensive field study in Korail. These insights helped us to identify fifteen product ideas, which were assessed on a range of criteria for viability. One of the worked-out solutions is a lid with vibrant colors made of recycled plastics to cover the aluminum pots used for storing water. Consequently, a lid and corresponding mould for local use with the plastic recycling machines of Precious Plastics were developed. The team also developed a business plan that is embedded in the network structure of the community and can be adopted by local entrepreneurs. The uniqueness of our approach lies in valorizing the use of local waste materials for products related to basic needs by stimulating DIY and grassroots level entrepreneurship.

During the big Tour de France time trial on the 15th of July 2016, Tom Dumoulin was cycling in a new suit, developed jointly by Team Giant-Alpecin and TU Delft. [TUDelft 2016] The drag of different suits was optimized in the Delft wind tunnel. However, as one can't place a professional cyclist in a wind tunnel for weeks on end. For this, a 3D printed mannequin with the exact same physical measurements was made. An essential benefit using an exact replica in the wind tunnel is that it remains perfectly still, making the measurements of the airflows around the body much quicker and more accurate. Additive manufacturing was not chosen as easiest option, it lead to a collection of research opportunities. The process includes scanning, 3D segmenting, printing strategy and printing, assembling and testing. The complete process wasdone in less then 2,5 months.
