DXF – Best Overall for CO₂ Laser Cutting
DXF (Drawing Exchange Format) is the most reliable and widely used format for CO₂ laser cutting.
Why DXF Is Best
- Clean vector lines
- Perfect for cutting paths
- Works with almost all laser software
- No font or layer confusion
- Accurate scaling
Supported Software
- LightBurn
- RDWorks
- LaserCAD
- AutoCAD
Best Use
- ✔ Cutting wood, acrylic, MDF
- ✔ Precision parts
- ✔ Production work
👉 Final Verdict:
DXF is the BEST file format for CO₂ laser cutting.
CDR – Best for Design & Text Work
CDR (CorelDRAW format) is excellent for designing, especially when text and layout matter.
Advantages
- Easy text editing
- Good for engraving
- Works well with RDWorks & CorelDRAW
Limitations
- Can create duplicate lines
- Needs cleanup before cutting
- Software-dependent
Best Use
✔ Designing signs
✔ Text-based engraving
✔ Artistic work
👉 Use CDR for design, then export to DXF for cutting.
SVG – Good for Hobby & LightBurn Users
SVG (Scalable Vector Graphics) works well with LightBurn and browser-based design tools.
Advantages
- Clean and lightweight
- Scales well
- Easy to create online
Limitations
- Not supported by all laser software
- Sometimes imports with stroke issues
Best Use
✔ LightBurn users
✔ Simple cutting projects
AI – Design Only, Not Direct Cutting
AI (Adobe Illustrator) is a professional design format, not a cutting format.
Advantages
- Best design control
- Clean vectors
- High quality artwork
Limitations
- Not directly supported by many laser machines
- Needs export to DXF or SVG
Best Use
✔ Design creation
❌ Not for direct cutting
Quick Comparison Table
| Format | Best For | Cutting Accuracy | Beginner Friendly |
|---|---|---|---|
| DXF | Cutting | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ |
| CDR | Design + Engraving | ⭐⭐⭐ | ⭐⭐⭐⭐ |
| SVG | LightBurn | ⭐⭐⭐⭐ | ⭐⭐⭐⭐ |
| AI | Design Only | ⭐⭐ | ⭐⭐ |
Final Answer: Which File Format Is Best?
👉 For CO₂ laser cutting → DXF
👉 For design & text → CDR or AI
👉 For LightBurn users → SVG or DXF
Common File Format Mistakes to Avoid
- Cutting directly from AI files
- Using unclean CDR files
- Not converting text to curves
- Ignoring duplicate lines
