The three mainstream technologies each serve a different purpose:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>FDM (Fused Deposition Modeling):<\/strong> thermoplastic filament (PLA, ABS, PETG) is melted and extruded through a nozzle. Lowest cost, ideal for early concept and size-check models.<\/li>\n\n\n\n<li><strong>SLA (Stereolithography):<\/strong> a UV laser cures liquid photopolymer resin point by point. It delivers the smoothest surface and finest detail of any printing technology \u2014 perfect for appearance models and presentation prototypes.<\/li>\n\n\n\n<li><strong>SLS (Selective Laser Sintering):<\/strong> a laser sinters nylon powder in a heated bed. Parts are strong, functional, and need no support structures \u2014 the go-to choice for functional testing, living hinges, and complex internal geometry.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Advantages<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fastest turnaround: parts in hand within 1\u20133 days, sometimes hours<\/li>\n\n\n\n<li>No tooling or setup cost \u2014 extremely economical for one-off and very low volumes<\/li>\n\n\n\n<li>Unmatched design freedom: undercuts, lattice structures, internal channels, and hollow forms are all printable<\/li>\n\n\n\n<li>Iteration is nearly free: change the CAD file, print again<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Disadvantages<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Material properties rarely match true production plastics; SLA resins can be brittle and UV-sensitive<\/li>\n\n\n\n<li>Visible layer lines on FDM and a slightly grainy finish on SLS often require sanding, polishing, or painting<\/li>\n\n\n\n<li>Anisotropic strength \u2014 parts are weaker along the layer direction<\/li>\n\n\n\n<li>Unit cost does not drop much with quantity, so it scales poorly beyond dozens of parts<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>2.
