This Master thesis describes the creation of Bebé: a design of an incentive for pregnant couples to live and eat healthy. This project was commissioned by the department of Obstetrics and Gynaecology of the Erasmus Medical Centre (MC) in Rotterdam, and executed as the final project of the Master Integrated Product Design at the Delft University of Technology. Each year around 200.000 women get pregnant in the Netherlands. At least 180.000 of those women, give birth to a living baby. Often, pregnant women and their partners are not aware of their responsibility for the unborn child during the first weeks of pregnancy. At that time, the baby does not move yet and there are little to none differences in external appearances of the mother. A healthy lifestyle and eating habits are very important during, and even before, pregnancy. The use of drugs and alcohol, smoking and experiencing stress can cause serious problems for the development of the unborn baby. The goal of this project was to come up with an incentive to pregnant couples to stimulate them and make them aware of a healthy lifestyle and eating habits. By creating the possibility for parents and caretakers to get a tangible product, providing them with a one to one 3D print of the embryo that is inside the mother's womb, an extra dimension was added to their pregnancy, as they can be more in touch with their baby and have an idea of the size, shape and appearance. Additive manufacturing, like 3D printing, is a technique that is very much upcoming. At this moment, 3D prints can be made from ultrasound or MRI scans. This opportunity – creating a 3D print from the data received by means of 3D ultrasound – served as the basis of this assignment. The process of getting from 3D ultrasound to 3D print was examined and different printing techniques, materials and machines were explored. To gain more knowledge into the products that are already offered during pregnancy and how couples are dealing with healthy lifestyle and eating habits, interviews were conducted with pregnant women and some of their partners. This study showed that many couples do not like the 3D ultrasound images that are offered. They even referred to it as ‘alien-like’. The idea of a 3D print was found to be more attractive. During the concept generation phase, a lot of ideas were generated, based on all information from the analysis phase. To receive the most out of it, multiple creative sessions were conducted with different people. By means of a small user evaluation at the end of this phase, the created concepts were ranked. This resulted in three final concepts, of which one was finally chosen to be developed further. This concept – Bebé – was further developed and embodied and a working prototype was made. During the embodiment phase, research was done on different shapes and materials. The functionality and usability of the product were tested during user tests with the prototype, after which recommendations were given. Bebé is a necklace that contains the embryo 3D print. The product protects the embryo 3D print that is inside by multiple layers and consists of 3 main parts: the embryo 3D print made out of plaster, making the pregnancy literally tangible, the necklace pendant, that can be worn around the neck of the expectant mother, and the necklace holder, in which the necklace can be stored or displayed when not being worn. These three parts together form a product that is conveying a greater message behind it: be responsible towards your unborn baby and make sure you live and eat healthy from the beginning of pregnancy onwards. Bebé is what you are doing it for.
