Sustainable construction of houses and construction kits with 3D concrete printing. "The capacity and flexibility to adapt to the client, to create the house of their dreams and enjoy it in a week, with the maximum guarantees of quality and the best price on the market" A3D, is an entrepreneurial initiative for the development of an advanced construction system 4.0 that allows the development of architectural elements of complex geometry. Applying the Lean Startup methodology, we defined our project with the minimum viable product, the result is "OVO Habitat", our first model of modular housing, cutting-edge design, multifunctional, eco-sustainable and smarthome. Designed by the Architect Robert Stuart-Smith (Copyright) based on this first design we have developed our business model, without forgetting the ability to offer customised products. This system reduces costs by a minimum of 30%, execution times by 70% and the associated financial costs by 25%. It is also a sustainable process, reducing CO2 levels, energy costs, water consumption and material waste. We are convinced that there is a window of opportunity to position A3D as a driver of change in the application of additive technology for Industry 4.0 in different sectors. Specifically, for the construction sector, we will generate the processes and methodology to go from design to the manufacture of housing.
