Not all 3D printers are the same. From budget-friendly home printers to high-precision industrial machines, each type has unique capabilities, costs, and use cases. Whether you’re a beginner, student, or product designer — knowing the differences can help you make the right choice.
🖨️ 1. FDM (Fused Deposition Modeling)
Most popular & beginner-friendly
- How it works: Melts and extrudes plastic filament (PLA, ABS) layer by layer
- Best for: Prototypes, mechanical parts, tools, hobby models
- Pros:
- Affordable (₹15,000–₹50,000 for home use)
- Easy to operate
- Works with many materials
- Cons:
- Less detail than resin printers
- Visible layer lines
Top Brands: Creality Ender Series, Prusa i3, Anycubic Kobra
💧 2. Resin Printers (SLA, DLP, LCD)
High-detail printing for miniatures, jewelry, art
- How it works: Uses UV light to cure liquid resin into solid layers
- Best for: Fine details, smooth surfaces, jewelry, action figures
- Pros:
- Extremely high resolution
- Smooth finish
- Cons:
- Resin is sticky and toxic (safety precautions needed)
- Requires post-processing (wash & cure)
Top Brands: Elegoo Mars, Anycubic Photon, Phrozen Sonic
🔥 3. SLS (Selective Laser Sintering)
Professional & industrial use
- How it works: Uses laser to fuse powdered nylon or polymer
- Best for: Functional parts, low-volume manufacturing
- Pros:
- Strong, durable parts
- No need for support structures
- Cons:
- Very expensive (₹5–20 lakhs)
- Large, complex machines
Used by: Automotive, aerospace, healthcare industries
