When entering the world of laser systems, understanding the difference between cutting and engraving is crucial. While many machines can do both, their functions vary significantly. This guide explains:
✔ Key technical differences
✔ How each process works
✔ Best machines for each application
✔ Material compatibility
✔ Which one you need
1. Fundamental Differences
| Feature | Laser Cutter | Laser Engraver |
|---|---|---|
| Primary Function | Through-cutting materials | Surface marking/etching |
| Power Requirement | Higher (50W-150W+) | Lower (5W-60W) |
| Speed | Slower (precise cuts) | Faster (surface work) |
| Depth Control | Full penetration | 0.1mm-2mm depth |
| Best For | Creating parts & shapes | Adding designs/text |
2. How Each Process Works
Laser Cutting
-
Process: Focused beam completely penetrates material
-
Settings:
-
High power (70-100% of machine capacity)
-
Slow speed (5-20mm/s depending on material)
-
Multiple passes sometimes needed for thick materials
-
Laser Engraving
-
Process: Beam vaporizes surface layers without cutting through
-
Settings:
-
Lower power (10-50% of capacity)
-
Faster speed (100-1000mm/s)
-
Can use variable depth for 3D effects
-
3. Material Compatibility
| Material | Cutting | Engraving |
|---|---|---|
| Wood | ✅ Best with 60W+ | ✅ Excellent |
| Acrylic | ✅ Clean edges | ✅ Frosted effect |
| Leather | ✅ Up to 8mm | ✅ Detailed designs |
| Metal | ❌ (Except with fiber) | ✅ With coatings |
| Glass | ❌ | ✅ (Frosted look) |
Key Insight: Most CO₂ lasers can do both, but fiber lasers are better for metal engraving/cutting.
4. Best Machines for Each Purpose
Best for Cutting
-
Boss LS-1630 (100W) - Professional-grade cutting
-
OMTech 60W - Best budget cutter
Best for Engraving
-
xTool P2 (55W) - Ultra-precise engraving
-
Epilog Fusion Edge - Industry-leading detail
Best Hybrid Machines
-
Thunder Laser Nova (100W) - Does both exceptionally
-
Trotec Speedy 400 - Fast switching between modes
5. Which One Do You Need?
Choose a Cutter If You Need To:
-
Make precise parts from materials
-
Create sign letters or mechanical components
-
Work with thicker materials (5mm+)
Choose an Engraver If You Need To:
-
Add personalized designs to items
-
Create detailed artwork or photos
-
Work primarily with thin materials
Get a Hybrid If You:
-
Want flexibility for different projects
-
Run a small business with varied needs
-
Have space for just one machine
6. Cost Comparison
| Type | Entry-Level | Professional |
|---|---|---|
| Engraver | 1,500−4,000 | 8,000−20,000 |
| Cutter | 3,000−6,000 | 15,000−50,000 |
| Hybrid | $5,000+ | $20,000+ |
Note: Many "engravers" can cut thin materials, while true "cutters" always engrave well.
7. Software Differences
| Task | Best Software |
|---|---|
| Cutting | LightBurn, RDWorks |
| Engraving | LightBurn, LaserGRBL |
| 3D Engraving | EzCad2, LaserCAD |
Pro Tip: LightBurn works excellently for both cutting and engraving.
Final Verdict
-
For pure engraving: A 40-60W machine with good detail
-
For serious cutting: 80W+ with air assist
-
For most users: A hybrid 60-100W machine offers best versatility

FAQs
Q: Can one machine do both perfectly?
A: Yes - 100W hybrids like Thunder Laser Nova handle both well.
Q: Why can't my 50W laser cut metal?
A: CO₂ lasers can't cut metal - you need a fiber laser (different wavelength).
Q: Is engraving cheaper than cutting?
A: Yes - uses less power and faster speeds.
