Abstract:
The use of prototypes in the product development process (PDP) brings maturity to the project, reduces uncertainties, and helps in the conservation of information flow during the whole PDP. Usually, virtual prototypes (VP) are created in CAD/CAE systems, while physical prototypes (PP) are usually manufactured from techniques of material addition. In this reality, the creation/manufacturing of a prototype capable to meet its purpose will depend on the alternative available for its creation/manufacturing, and on the experience of the professional involved (designer). This work proposes a procedure to help in the selection of the best creation/manufacture technique for VP and PP, initially focusing on the automotive sector. The procedure was developed from theoretical backgrounds, discussion and consideration among professionals and scholars. The procedure was evaluated in a field research, where 34 professionals from 23 different companies of the automotive sector had been consulted. The theoretical frameworks, the proposed procedure, and the results of the field research are presented. Finally, the work is finished showing the conclusions and final considerations. The use of this procedure is expected to help experienced professionals and beginners, as well as scholars, in their research, education, and extension activities.
