It was invented and patented by Chuck Hull in 1986.<\/li><li class=\"translation-block\"><strong>Digital Light Processing<\/strong> (DLP) is the technology commonly used to project digital images. EnvisionTEC developed the technology whereby this technology could be used to, like SLA, cure layers of light-curing resin to manufacture three-dimensional parts.<\/li><li class=\"translation-block\"><strong> Digital Light Manufacturing<\/strong> (cDLM). Just as DLP is an advance over SLA, especially in terms of speed, cDLM technology innovates over DLP by multiplying its printing speed and bringing 3D printing using photocurable resins to the field of mass manufacturing of the final part.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Note: SLA technology is typically used by immersing the platter in a VAT, from top to bottom, and DLP by suspending the part in the air, bottom to top. However, both technologies occasionally use both techniques. The only difference ever, between SLA and DLP, is the light source (a traveling laser or a full surface projection).<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"941\" height=\"1024\" data-src=\"https:\/\/delteco.juanma.app\/wp-content\/uploads\/2022\/01\/sla-vs-dlp-vs-cdlm-941x1024.png\" alt=\"\" class=\"wp-image-3032 lazyload\" data-srcset=\"https:\/\/delteco.juanma.app\/wp-content\/uploads\/2022\/01\/sla-vs-dlp-vs-cdlm-941x1024.png 941w, https:\/\/delteco.juanma.app\/wp-content\/uploads\/2022\/01\/sla-vs-dlp-vs-cdlm-276x300.png 276w, https:\/\/delteco.juanma.app\/wp-content\/uploads\/2022\/01\/sla-vs-dlp-vs-cdlm-768x836.png 768w, https:\/\/delteco.juanma.app\/wp-content\/uploads\/2022\/01\/sla-vs-dlp-vs-cdlm-1412x1536.png 1412w, https:\/\/delteco.juanma.app\/wp-content\/uploads\/2022\/01\/sla-vs-dlp-vs-cdlm-1882x2048.png 1882w, https:\/\/delteco.juanma.app\/wp-content\/uploads\/2022\/01\/sla-vs-dlp-vs-cdlm-600x653.png 600w\" data-sizes=\"(max-width: 941px) 100vw, 941px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 941px; --smush-placeholder-aspect-ratio: 941\/1024;\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Stereolithography or SLA<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How it works?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In a container of photocurable or photopolymeric resin (VAT), it is submerged layer by layer. In each layer, a zenithal laser cures said resin, joining the first cured layer to the plate and the subsequent ones to each previous layer. In this way, when printing ends, the printed part is submerged in the bottom of the VAT.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Strengths<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Produce parts with high definition.<\/li><li>Permite la fabricaci\u00f3n de piezas de gran tama\u00f1o (hasta 1,5 metros)<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Weaknesses<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Since the laser has to travel to draw the section of the part at each layer, just like an FDM printer does when depositing material, it is a very slow technology.<\/li><li>Since the VAT is large, and SLA resins densify over time, the entire contents of the VAT must be discarded periodically and replaced with fresh resin. This makes the technology much more expensive to use than initially estimated.<\/li><li>For the same reason, the size of the VAT and its high resin content, using different resins for different applications is complex and expensive.<\/li><li>It is only possible to print parts as tall as the depth of the VAT. The greater the height of the desired part, the greater the volume of resin that the VAT must contain, with all that it entails.<\/li><li>The post-processing of the printed pieces includes a wash in isopropyl alcohol and the manual removal of the supports that held them during the printing process.<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">References<\/h4>\n\n\n\n<ul class=\"wp-block-list\"><li class=\"translation-block\">Wikipedia about <a href=\"https:\/\/en.wikipedia.org\/wiki\/Stereolithography\" target=\"_blank\" rel=\"noreferrer noopener\">Stereolithography. <\/a><\/li><\/ul>\n\n\n\n<div style=\"height:35px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Digital Light Processing o DLP<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How it works?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Similar to SLA technology, this technology cures resin layers. However, the light for curing is emitted from the bottom, up, and using a DLP projector, and the plate rises into the air layer by layer.

This technology ensures that the piece, as it cures layer by layer, is never really in contact with said bottom of the tray. As a consequence, there is no adhesion factor between the part and the tray, nor is a separation process necessary, which greatly speeds up the printing process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is not about the projector projecting and curing faster.
