Tech Explainer: 3D Printing

Imagine a machine that crafts objects layer by layer, from jewelry to satellite parts That's 3D printing, a process transforming how we create and innovate Let's take a look at the 3 most popular types of 3D printing 1. Stereolithography (SLA) It uses UV lasers to solidify photosensitive resin, layer by layer 2. Fused Deposition Modeling (FDM) This technique prints high-strength thermoplastic, perfect for engineering 3. Digital Light Processing (DLP) Similar to SLA but uses arc lamps, enabling high-speed printing In healthcare, 3D printing produced ventilator parts during the pandemic Aerospace companies use it for rapid prototyping, slashing research costs and time Even automakers benefit, replacing worn parts on the fly
