Life Cycle Assessment Theories into Circular Economy -- Use of composite materials in the design of a ventilation grille attending to eco-sustainability factors -- Improvement in the design of a front hub for the BMX bicycle -- Prosumer and product design through digital tools -- Sustainability assessment in the implementation phase of a retail space -- Comparative Analysis of Ecodesign in the Design and Manufacturing Methods for Mechanical Parts made of Nylon PA6 -- Co-creative experiences for the achievement of the sustainable development goals.

This book gathers the papers presented at the XXIX International Congress INGEGRAF "The digital transformation in graphic engineering," which was held in Logroño, Spain on June 20-21, 2019. It reports on cutting-edge topics in product design and manufacturing, such as industrial methods for integrated product and process design; innovative design; and computer-aided design. Further topics covered include virtual simulation and reverse engineering; additive manufacturing; product manufacturing; engineering methods in medicine and education; representation techniques; and design and modeling for nautical, engineering and construction, aeronautics and aerospace contexts. The book is divided into six main sections, reflecting the focus and primary themes of the conference. The contributions presented here will not only provide researchers, engineers and experts in a range of industrial engineering subfields with extensive information to support them in their daily work, but will also stimulate new research directions, advanced applications of the methods discussed, and future interdisciplinary collaborations.
