DRAWING BY COMPUTER BIM, ARCHITECTS AND ARCHITECTURE FIRMS TEND TO RELY ON 3D PRINTING

In Architecture drawing by computer is widely used in the architect community, more and more the studio architects’ and the ateliers of architects demand the professional who collaborates in the tasks of production and drawing of the architectonic planes, with more knowledge in computer drawing. Lately the introduction of the presentations in three dimensions and multimedia causes the professional to get knowledge on these means and their uses.

The virtual pads introduce a fundamental concept in drawing up plans or plan survey. But a problem exists, to access to the virtual graphical representation without the necessary maturity in the field of the Architectonic Presentation.

From the Technical University of Madrid, we must begin to stimulate the new forms to express the architecture, imaginary or constructed, and to express our work with a clear and concise language.

Until recent years models were built by hand, often taking a long time. Thus, architects are often forced to show their clients drawings of their projects. According to Erik Kinipper, clients usually need to see the product from all possible viewpoints in space to get a clearer picture of the design and make an informed decision. In order to get these scale models to clients in a small amount of time, architects and architecture firms tend to rely on 3D printing Using 3D printing, these firms can reduce lead times of production by 50 to 80 percent, producing scale models up to 60 percent lighter than the machined part while being sturdy. Thus, the designs and the models are only limited by a person's imagination.

The improvements on accuracy, speed and quality of materials in 3D printing technology have opened new doors for it to move beyond the use of 3D printing in the modeling process and actually move it to manufacturing strategy. A good example is Dr. Behrokh Khoshnevis' research at the University of Southern California which resulted in a 3D printer that can build a house in 24 hours .Using this process, a single house or a colony of houses, each with possibly a different design, may be automatically constructed in a single run, embedded in each house all the conduits for electrical, plumbing and air-conditioning.

A building information model contains not only the design of a building but data concerning the properties of its components, its construction and ongoing maintenance. The impression 3D is one of the big trends of last years in the technological area. In fact we see little by little since different models of printer go out to the consumer market 3D that you can buy so much across Internet as in department store. Nevertheless, the impression 3D has much more behind what it seems in the first instance. Our pupils make models with a printer 3D model MARKETBOT REPLICATOR TM 2 DESKTOP 3D PRINTER. We can see some examples of their works.

We must think that independently of the used technique, the most important thing is to know the aim a priori that we want to obtain, since this is the only mean to get it. For that reason, a constructive understanding of the architectonic work is advisable, before realizing any representation of the same, and based on it, we will choose the more suitable technique of representation.
