El proceso comienza con un modelo digital, que se puede crear utilizando software CAD (dise\u00f1o asistido por computadora), obtenido de un esc\u00e1ner 3D o descargado de repositorios en l\u00ednea. A continuaci\u00f3n, el modelo se importa al software de corte, que lo divide en numerosas capas de secci\u00f3n transversal bidimensional que sirven como un plan para la impresora. El software de corte luego convierte estas capas en una serie de instrucciones, a menudo en el c\u00f3digo G, que la impresora 3D puede entender. Adem\u00e1s, si el modelo contiene piezas sobresalientes, el software puede generar estructuras de soporte para garantizar una impresi\u00f3n adecuada.

Con una investigaci\u00f3n continua en nuevos materiales y avances tecnol\u00f3gicos, han surgido m\u00e1s t\u00e9cnicas de impresi\u00f3n 3D. Los tipos comunes hoy incluyen:<\/p>\n<!-- \/wp:paragraph -->\n\n<!-- wp:list -->\n<ul class=\"wp-block-list\"><!-- wp:list-item -->\n<li><strong>FDM (modelado de deposici\u00f3n fusionado):<\/strong>Works by heating a thermoplastic filament, extruding it through a nozzle, and depositing it layer by layer. FDM is affordable, easy to use, and accessible for users of all skill levels. It supports large prints with the right machine setup and is suitable for architectural models, industrial design, and large-scale prototypes. However, it does not handle overhangs and fine details well and often requires support structures. FDM parts may have visible layer lines and weaker adhesion along the Z-axis, making them prone to delamination under stress.<\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><strong>SLA (estereolitograf\u00eda):<\/strong> Uses ultraviolet light to cure successive layers of liquid photopolymer resin. SLA prints have fewer visible layer lines compared to FDM and can produce ultra-smooth surfaces with fine details, making them popular for jewelry, dental models, and intricate prototypes.<\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><strong>DLP (procesamiento de luz digital):<\/strong>Another resin-based 3D printing method, but instead of a laser, it uses a digital projector to cure an entire layer of resin at once. This makes DLP faster than SLA. DLP parts have sharp edges and crisp details and can be used in similar applications as SLA. However, they may sometimes show visible pixelation and typically have a smaller build area.<\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><strong>SLS (sinterizaci\u00f3n l\u00e1ser selectiva):<\/strong>Uses a high-powered laser to sinter powdered materials, such as nylon and TPU, layer by layer. The unsintered powder acts as support, enabling interlocking, overhanging and other complex designs that are difficult to produce with other methods. SLS parts have good mechanical strength but tend to have a slightly grainy texture.<\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><strong>DMLS (sinterizaci\u00f3n de l\u00e1ser de metal directo):<\/strong> An extension of SLS, specifically designed for processing metal powders. It partially melts powder particles to fuse them together at a molecular level, resulting in slightly porous parts that may require post-processing, such as hot isostatic pressing, to achieve full density. Unlike SLS, DMLS needs support structures\u2014which must be manually removed after printing\u2014to counteract thermal stress and warping during the process.<\/li>\n<!-- \/wp:list-item -->\n\n<!-- wp:list-item -->\n<li><strong>SLM (derretimiento l\u00e1ser selectivo):<\/strong>Also uses a high-power laser to produce metal parts, but unlike SLS, SLM fully melts the metal powder, creating 100% dense parts with superior mechanical strength, hardness, and durability, even comparable to cast or forged metal components. It works best with pure metals and select alloys. SLM generates higher thermal stress which can lead to warping and cracking. Stronger support structures are required to reduce these stresses.<\/li>\n<!-- \/wp:list-item --><\/ul>\n<!-- \/wp:list -->\n\n<!-- wp:heading -->\n<h2 class=\"wp-block-heading\">\u00bfQu\u00e9 es el mecanizado CNC?<\/h2>\n<!-- \/wp:heading -->\n\n<!-- wp:image {\"id\":3011,\"sizeSlug\":\"full\",\"linkDestination\":\"none\"} -->\n<figure class=\"wp-block-image size-full\"><img src=\"https:\/\/chiggofactory.com\/wp-content\/uploads\/2025\/03\/CNC-Machining-Process.jpg\" alt=\"CNC Machining Process\" class=\"wp-image-3011\"><\/figure>\n<!-- \/wp:image -->\n\n<!-- wp:paragraph -->\n<p>Mientras que la impresi\u00f3n 3D es un proceso de fabricaci\u00f3n de aditivos de vanguardia, el mecanizado CNC (mecanizado de control num\u00e9rico de la computadora) representa una t\u00e9cnica de fabricaci\u00f3n de sustractivas m\u00e1s tradicional.
