3D AIR DRAWING BY ARTIST HÉCTOR LARA

ART AND TECHNOLOGY

“The 3D drawing jumps out into reality to blend with our surroundings. Drawing in the air is now possible thanks to the 3D pen used by Lara”

We live in a revolutionary era where technology has become of great importance in our lives and takes part in different aspects of it.

Technology has advanced so much that is has been introduced in such basic forms of art such as drawing.

Artist Héctor Lara has been investigating three-dimensional drawing with the 3D pen for the past few years. Thanks to that pen, one can actually create drawings in the air.

His investigation with the 3D pen has been so important that he is currently sponsored by one of the biggest multinational 3D pen developers: “Lixpen”.

The 3D pen has plastic filaments called “abs” instead of ink. This patented Lix technology allows the 1.75 mm diameter plastic filament to melt and cool in just a few seconds.

A 3D pen works very much like a 3D printer: when it prints an object, it uses a heated extruder and a filament that is extruded through a nozzle. This extruder ensemble is connected to a carriage that can be moved with precision through axes X, Y and Z, Cartesian coordinates. A 3D pen eliminates this entire control system and makes the user’s hand the extruder ensemble.

Because of its nature, this material has a number of limitations, just like all other materials. Due to the fact that it’s plastic material, during the first tests of the instrument’s investigation the artist Héctor Lara could saw that the result was too malleable. So, after a large field study on architecture, he decided to apply the theory of triangulation.

This method is applied in a way that a series of bar gratings create triangular structures. These triangles are connected by rigid joints or knots, which provides greater stability and rigidity to what is built, so that the stresses to which these bars are subjected work as compression and traction axles.

This principle is used in construction of large structures that need to support large stress loads such as bridges.

This same theory was applied for three-dimensional figure drawing in order to create more rigid structures, and eventually led to the technique that Héctor Lara called “Geometrism”, which combines the principles of architecture and 3D drawing.

A new concept of cutting-edge drawing techniques that has never been seen before. Drawing is no longer limited to a flat area, now it can jump out into reality and become part of our surroundings.
