These have made it possible to print very sophisticated objects, to multiply applications and to produce printers that are accessible for small businesses and domestic use.<\/p>\n<p>This is a suggestive and complex subject. It is discussed <strong>in some of its different areas<\/strong> below.<\/p>\n<p><span class=\"titulo-pers-4\"><strong>What is a 3D printer?<\/strong><\/span><\/p>\n<p>Just as the traditional printer enable users to move a text from a computer to a sheet of paper, <strong>3D printers make it possible to reproduce an object in its three dimensions<\/strong> (length, breadth and depth). In other words, if one has computer access to the three-dimensional data of an object, however simple or complex it may be, the 3D printer will \u201cmove\u201d it into reality, as something that is literally within the user\u2019s reach.<\/p>\n<p><span class=\"titulo-pers-4\"><strong>Technology and Types<\/strong><\/span><\/p>\n<p>The technology makes use of <strong>3D software to design the object and \u201ctranslate\u201d the information into 2D layers which then generate its three-dimensional replication<\/strong>. However, 3D printers are developing so fast that new models are continually being presented and marketed. In order to give a general idea of the different types that presently exist, we have opted to provide a synthesis of information that may be found in Wikipedia:<\/p>\n<p><strong><span style=\"text-decoration: underline;\">The compression type<\/span><\/strong><strong>: <\/strong>a mass of powder (plaster or cellulose) is compressed by strata.<\/p>\n<p>Depending on the method used for compression, one may use printers with an <strong>inkjet system that accumulates layers<\/strong>, making it possible to print in colours, and the <strong>laser type<\/strong> in which a laser beam transfers energy to the powder causing it to polymerise. It is then immersed in a liquid that solidifies the polymerised zones.<\/p>\n<p>Once all the layers are printed it is only necessary to take out the piece. Any surplus powder is then removed by means of a vacuum cleaner and reused for subsequent printing.<\/p>\n<p><strong><span style=\"text-decoration: underline;\">Printers using additive processes or polymer deposition<\/span><\/strong>: the object is gradually \u201cconstructed\u201d by <strong>adding layers of material<\/strong> (plastic, metal, et cetera), <strong>which give it body<\/strong>.<\/p>\n<p>Another kind of 3D printing technology functions by <strong>injecting resins in liquid state<\/strong>, which are then cured by ultraviolet light. These are acrylic-based photopolymers with different physical-mechanical properties, for example varying degrees of flexibility, elongation at break, resistance, colours, and so on. They are notable for their precision and surface finish, which means that they are highly suitable for \u201cmould construction\u201d. The pieces are totally cured by the end of the printing process and there is no waiting time, although water jetting is necessary for removing the printing accessories. This technology has been the first to achieve the injection of two different materials in one printing, which then makes it possible to produce digital materials with \u201c<i>\u00e0 la carte<\/i>\u201d properties.<\/p>\n<p><span class=\"titulo-pers-4\"><strong>Applications<\/strong><\/span><\/p>\n<p>Until now, the printers have been used almost exclusively in <strong>architecture<\/strong> and <strong>industrial design<\/strong>. Now there seems to be an endless array of applications: <strong>decorative<\/strong> objects, <strong>household goods<\/strong>, items of <strong>clothing<\/strong>, <strong>footwear<\/strong>, sets for the film industry, food (hamburgers, cakes, and so on), human organs and tissue \u2026 the limits are set by the human imagination. Some examples are given below.<\/p>\n<figure id=\"attachment_1082\" aria-describedby=\"caption-attachment-1082\" style=\"width: 567px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-1082 lazyload\" data-src=\"\/wp-content\/uploads\/2013\/08\/1_3d-printers-a-boom-in-technology.jpg\" alt=\"Image taken from a video by the company Tecnonauta.\" width=\"567\" height=\"314\" title=\"\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 567px; --smush-placeholder-aspect-ratio: 567\/314;\"><figcaption id=\"caption-attachment-1082\" class=\"wp-caption-text\"><span style=\"font-size: 10px; color: #888;\">Image taken from a video by the company Tecnonauta.<\/span><\/figcaption><\/figure>\n<p>Anecdotes aside, the most remarkable features of these printers are their <strong>biomedical<\/strong> <strong>applications<\/strong> and the fact that companies in the field can quickly test the efficacy of <strong>prototypes<\/strong>, thus considerably cutting costs.<\/p>\n<p><span class=\"titulo-pers-4\"><strong>Some Examples<\/strong><\/span><\/p>\n<p><strong>The bone printer <\/strong>(3D Bioprinter)<\/p>\n<p>This is capable of using<strong> stem cells <\/strong>to producebones to replace defective ones.

The material used in the process will be absorbed by the child\u2019s organism in three years (The New England Journal of Medicine).<\/p>\n<p><strong>Device for making iced drinks<\/strong><\/p>\n<p>The Institute of Design and Manufacturing (<strong>IDF<\/strong>) at the Technical University of Valencia (UPV), Spain, has created a new <strong>device for making crushed-ice drinks<\/strong> for a company that manufactures the traditional drink <i>horchata <\/i>(made from tiger nuts). This has been designed by means of a 3D printing process, thus reducing costs in the design phase by working with short deadlines and facilitating decision making.<\/p>\n<p>Recently, researchers at the University of North Carolina have developed a method of \u201cprinting\u201d with liquid metal (see video below).<\/p>\n<p><span class=\"titulo-pers-4\"><strong>Prices<\/strong><\/span><\/p>\n<p>Until very recently, prices were as high as 500,000 euros, which means that 3D printers could only be afforded by big companies and well-funded research institutions. It should be borne in mind that the cost includes that of the <strong>machine<\/strong> itself, the <strong>software<\/strong> and the <strong>cartridges <\/strong>of the materials used in the printing process. Nonetheless, increasing competition in the market is bringing prices down, and printers for domestic use and for small businesses are now being produced for 500 euros and upwards. Naturally, the price depends on the printer\u2019s <strong>resolution capacity<\/strong>. In order to make them more affordable, some manufacturers are even selling models in <strong>self-build kits<\/strong>.<\/p>\n<figure id=\"attachment_1091\" aria-describedby=\"caption-attachment-1091\" style=\"width: 584px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.rtve.es\/alacarta\/videos\/telediario\/impresoras-3d-alcance-cualquiera\/1890808\/\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"size-full wp-image-1091 lazyload\" data-src=\"\/wp-content\/uploads\/2013\/08\/2_3d-printers-a-boom-in-technology.jpg\" alt=\"Spanish Television (TVE) video: Las impresoras 3D al alcance de cualquiera (The 3D Printers That Everyone Can Afford).
