3D printing or rapid prototyping is the process that generates mock-ups or tridimensional, solid objects, using a digital project.
The printing is done by applying successive layers of material, each layer with stiffener substances and the colors described in the virtual model.
There can be printed objects of various complexity, parts or entire systems. The extraordinary realism of the 3D products and mock-ups allows designers, architects, engineers and product managers to study carefully the proposed concepts and make rapidly the best marketing or sales decisions.
