“One size fits all” solutions went out of fashion a long time ago. Customers much prefer to buy products that are personalized and that emphasize their individuality, so mass customization (customer-specific mass production) has long been a trend of our time. Whether it’s chocolate buttons featuring your own face, customized sneakers, cereal that you create yourself, individually designed packaging or shampoo that is tailored to your hair’s needs, mass customization can be found in almost all industries. Customized products are not a new idea in themselves; before industrialization, individual products made to order for local requirements were the norm. Thanks to 3D printers and highly adaptable production systems, this level of personalization is now possible even for mass-produced products. This means that products are individualized, but still automated.
