Introduction
3D printing, also known as additive manufacturing, has transformed the way industries prototype and produce components. Unlike traditional subtractive methods, 3D printing builds objects layer by layer, allowing for greater design flexibility, reduced material waste, and faster production.
Types of 3D Printing
| Technology | Process | Common Materials | Applications |
|---|---|---|---|
| Fused Deposition Modeling (FDM) | Heated filament is extruded through a nozzle, layer by layer | PLA, ABS, PETG, Nylon | Prototyping, hobbyist projects, automotive parts |
| Stereolithography (SLA) | Uses a UV laser to cure liquid resin into solid layers | Resin, tough resin, flexible resin | Jewelry, dental models, high-detail prototypes |
| Selective Laser Sintering (SLS) | Uses a laser to fuse powdered material into solid objects | Nylon, TPU, metal powders | Aerospace, medical implants, functional parts |
Advantages Over Traditional Methods
✅ Faster Prototyping – Reduces development time from weeks to hours.
✅ Cost-Effective – Lowers production costs by minimizing material waste.
✅ Complex Designs – Creates intricate geometries that are impossible with conventional machining.
