Emergent product design practices in the era of additive manufacturing.

AM can make shapes that would be impossible or at least very difficult with traditional manufacturing methods that rely on material removal or forming such as moulding or casting. AM capabilities and opportunities include shape complexity, multi-materials, on-demand production, personalisation, and 4D Printing. Recent years have witnessed the emergence of end-use products manufactured via AM, and this is likely to grow in the future (Wohlers, 2020).
