The study aims to understand the impact of new digital design and manufacturing tools on the design process. Digital manufacturing technologies are having far reaching impacts on design, however there is currently little understanding about how this is affecting the design process. The paper reports on an interview study with twelve designers who use new digital manufacturing tools, in architecture, ceramic design, product design and jewellery design. Data is gathered and analysed using a grounded theory approach. The study shows that the design process is defined by the relationships between digital design tools, digital manufacturing tools and digitally manufactured objects. The nature of these relationships vary in direction and degree of formalisation, and they are discovered to influence three key factors in the design process: (1) emergence and control; (2) creativity and, (3) design skills. The study provides new insight into the design process, as well as providing an integrated view of digital design and digital manufacture, identifying areas for further research.
