A 3D model is created using CAD software (e.g., Fusion 360, Tinkercad) or obtained via 3D scanning.
The design is exported as an STL or OBJ file, which the printer can read.
Slicing software (like Cura or PrusaSlicer) cuts the 3D model into thin horizontal layers (typically 0.05–0.3mm thick).
The software generates G-code, which contains instructions for the printer (e.g., temperature, speed, layer height).
Depending on the technology, the printer deposits or solidifies material:
FDM (Fused Deposition Modeling) – Melts plastic filament and extrudes it through a nozzle.
SLA/DLP (Stereolithography) – Uses UV light to harden liquid resin.
SLS (Selective Laser Sintering) – Fuses powder (plastic/metal) with a laser.
Binder Jetting – Glues powder layers together with a liquid binder.
Removing supports (for FDM/SLA prints).
Cleaning excess powder (for SLS/metal prints).
Sanding, painting, or polishing for a smoother finish.
| Technology | How It Works | Materials Used | Best For |
|---|---|---|---|
| FDM | Extrudes melted plastic | PLA, ABS, PETG | Prototypes, hobbyists |
| SLA/DLP | UV-cures liquid resin | Photopolymers | High-detail models, dentistry |
| SLS | Laser-sinters powder | Nylon, metals | Functional industrial parts |
| Metal 3D Printing | Melts metal powder | Titanium, aluminum | Aerospace, medical implants |
✅ Complex Designs – Create shapes impossible with traditional methods.
✅ Rapid Prototyping – Test designs quickly and cheaply.
✅ Customization – Perfect for medical implants, prosthetics, and personalized products.
✅ Less Waste – Only uses the material needed (unlike machining).
Healthcare – Custom prosthetics, dental aligners, surgical models.
Aerospace – Lightweight aircraft components.
Automotive – Prototyping, custom car parts.
Fashion – 3D-printed shoes and jewelry.
Faster Printing – New technologies like CLIP (Continuous Liquid Interface Production) speed up the process.
Multi-Material Printing – Combining plastics, metals, and even electronics in one print.
Bioprinting – Printing human tissues and organs for medical use.
3D printing is transforming industries by making manufacturing faster, cheaper, and more customizable. Whether you're a hobbyist, engineer, or medical professional, this technology offers endless possibilities.
