Integrating a 3D development platform into company processes enables every stage to be optimised: from the concept to its prototyping, thanks to a 3D configurator equipped with the necessary tools to connect the work of everyone involved. 3D technologies also enable the limitations of mass production to be overcome once and for all in favour of Mass Customisation. The 3D Printer makes Mass Customisation sustainable in terms of production "on demand", without the constraints of economies of scale. Welcome to the Industry 4.0 era.
