There are a large number of technologies that leave a certain mystery about how they work. Unraveling the details of machines, such as 3D printers, helps to understand this technology that has been with us for several years now, but which still offers a great mystery both for neophytes of the subject and for people who have taken the first step in this world. Today it is possible to enjoy technologies that were unthinkable years ago. Being able to recreate objects in a reliable way, with great detail, is now possible thanks to machines such as 3D printers, really interesting resources for many professionals and individuals, which can now bring to reality any idea or object they have in mind , practically on the scale you want.

A first idea about how a 3D printer works

 For all those people who are unfamiliar with this world of three-dimensional printing, it is necessary to understand that these machines have the objective of bringing practically any object that comes to mind to reality. These printers physically and tangibly recreate any design, plan or model. In this way, it is possible to obtain objects such as figures, pieces, prototypes, etc. to scale, with truly incredible accuracy, and with the appropriate robustness for its use and subsequent purpose.

How are objects recreated in three dimensions?

Through a series of programs, and with the appropriate software (For example Solidworks Autodesk Inventor o Catia) A process known as the "additive process" is carried out for each 3D printer model. We must have a suitable file compatible with our printer program so that it can properly interpret the measurements and parameters of the object. It is important to know the compatibility, versions and updates of the programs we use, since at certain times they could cause problems if we do not have the latest version of the software we use. Taking into account the dimensions of the object to be recreated; both its height, width and length, printers add volume and body to the object, through a series of diverse materials: from nylon, thermoplastic filaments, and even certain metals and special materials, to outline the object, little by little, until its final completion. 3D printers mold these materials little by little by means of heat, since it allows them to be handled and adapted appropriately to form the final shape. Little by little the malleable material is “injected”, at the right temperature, through layers. In this way, it can be seen how, when printing, the printer recreates both the height and width of the object. Among the various materials previously discussed, used in three-dimensional printing. It is important to note that the most common are FilaFlex, ABS, PLA or HIPS, which, depending on the object to be reproduced, have a greater or lesser suitability.

Why print objects using 3d printing?

3D printers offer a large number of advantages, not only in the professional field. Its use is an effective way to recreate objects, such as spare parts that are not possible to acquire online. In this way, if, for example, a machine, a piece of furniture or even a single manufactured product, needs a certain object, a certain measure and a certain flexibility, 3D printing is the best option. Although 3D printing is currently in its initial phase, little by little it is possible to observe how it tries to cover more important and ambitious projects. In the coming years, it is expected that three-dimensional printing may include the recreation of modules, walls and final structures to be able to recreate homes and large buildings. 3D printing promises to bring great news and surprises in the coming years. Printing objects in three dimensions by means of a printer is a really advisable way if we want to obtain perfectly functional pieces, or models as models or sketches, that serve to be able to build more complex models on a larger scale. In a short time, thanks to the layer addition system (around 0.1 millimeter thick) from the bottom to the top, you can get really valid and functional pieces. 3D printing promises to become in the coming years, a benchmark for both amateurs and professionals who want to expand their knowledge in this wonderful world of object printing. Something that is expected to expand little by little to all areas and all technological fields. Because of the enormous possibilities offered by this type of machine, which for the moment recreates simple parts, but which in the not too distant future may form part of much more complex structures; such as large machines, modular constructions for homes or factories or pieces specially designed to apply in scientific fields, such as the recreation of small valves or organs that replace the real ones of our body damaged by the passage of time or due to malfunction.
