This research is the result of work carried out by the PIE-DIBARQ Group of Educational Innovation ETSEM-UPM during the 2016-2017 courses in its effort to implement a methodology adapted to the new requirements of European Convergence in Higher Education through the use of new technologies and the introduction to them for the students. Nowadays we are not only teaching conventional techniques, but they're trying, at least experimentally, to show each student more innovative ways in Architectural Representation. This is the case of the use of computers, and the new language BIM. We are not only referring to the computer-assisted instruction, where the teacher is developing several experimental units as fixing the theoretical concepts taught, but also to the use and knowledge of the computer as an element used by the professional as a graphic expression of their ideas, or studies. Although the concept of 3D printer has its origin in the 80's it is now taking more and more strength, and it is already starting to be used in many industries. The future of 3D printers is promising and from 2014 we begun to be more familiar with them and for sure we will get better printer with a lower prices. The 3D printer is considered by the European Space Agency (ESA) as a pioneering invention of the Third Industrial Revolution, as the steam engine and the internal combustion engine were once. The ability to print anything we have in our computer modelling before is a real change in our conception of production, being classified by experts as disruptive technology more powerful than the Internet itself. If it was possible to print parts for spaceships, food and even human organs, the range of possibilities expands the conception of a giant 3D printer in 24 hours can build a house of more than 200 square meters. Although this is the future of printing the truth it is that when one starts to learn seriously about a 3D printer, discovers with some frustration that the information accessible is rather fanciful. Much is written about the potential of these machines, and we found images of beautiful sculptures of impossible shapes, jewellery or accessories that seem to be taken from a workshop of professional jewellery. In this paper we will see the problems and resolution of the 3D printing in Architecture.
