The scope of 3D printing is enormous and has had a great impact in several fields, among which we can mention:

• Medicine: the most recent example occurred during the COVID pandemic in 2020. In Europe and other parts of the world the number of ventilator valves in hospitals was insufficient. Many collaborated in taking the design of the valves to print them in 3D, one of them was the British manufacturer Photocentric. Another example in this field is the printing of prostheses in 3D.

• Architecture and engineering: support in the fast production of conceptual models. In addition, for the reproduction of non-existent parts of equipment or machinery. Or for the creation of molds to be able to use a different material than the one supported by the printer.

There are even houses that were fully 3D printed. For example, in Eindhoven, Netherlands, there is the first house made with a 3D printer using specially formulated concrete. Another example is in Germany, where a two-level house of 160 m2 was built (printed).
