🔰 The Basics of 3D Printing – A Beginner’s Guide
3D printing, also known as additive manufacturing , is the process of creating physical objects from a digital design. Unlike traditional manufacturing, which cuts or molds material, 3D printing builds objects layer by layer , making it possible to create complex shapes with minimal waste. 🧱 How Does a 3D Printer Work? At its core, a 3D printer works like this: Design : Start with a 3D model, usually made using software like Tinkercad, Fusion 360, or Blender. Slice : The model is sliced into thin horizontal layers using a slicer program like Cura or PrusaSlicer. Print : The printer follows those slices and prints layer by layer using a material like plastic filament, resin, or even metal. 🛠️ Common Types of 3D Printers FDM (Fused Deposition Modeling) : The most common type; uses plastic filament like PLA or ABS. Great for beginners and hobbyists. SLA (Stereolithography) : Uses UV light to harden liquid resin. Offers high detail—perfect for miniatures and prototy...
