Choosing between a 40W laser and a higher-power model (60W, 100W, 150W+) depends on your projects, materials, and budget. Let’s break down the key differences to help you decide.

1. Cutting & Engraving Capabilities

📌 40W Lasers (Entry-Level Power)

✅ Best For:

• Thin wood (6-8mm plywood)

• Acrylic (4-6mm)

• Leather, fabric, paper

• Light engraving

❌ Limitations:

• Struggles with hardwoods (oak, maple)

• Slower cutting speed (more passes needed)

• Not for thick materials (above 10mm)

📌 60W-100W Lasers (Mid-Range Power)

✅ Best For:

• Thicker wood (12-18mm plywood)

• Faster engraving & cutting

• Hardwoods (8-12mm)

• Small business production

❌ Limitations:

• More expensive ($4K-$12K)

• Larger size (needs more space)

📌 150W+ Lasers (Industrial Power)

✅ Best For:

• 20mm+ wood & acrylic

• High-speed production

• Industrial fabrication

❌ Limitations:

• Very expensive ($15K-$50K+)

• Overkill for hobbyists

2. Speed & Efficiency Comparison

💡 Example: Cutting 6mm plywood

• 40W: 2-3 passes at 10mm/s

• 100W: 1 pass at 20mm/s

• 150W: 1 pass at 30mm/s

3. Material Compatibility

4. Cost Comparison

5. Who Should Choose Which?

✔ Choose a 40W Laser If:

• You’re a beginner testing laser cutting

• You work with thin wood/acrylic (under 8mm)

• You have a tight budget ($2K-$4K)

• Your projects are small-scale (jewelry, gifts)

✔ Choose a 60W-100W Laser If:

• You run a small business (Etsy, custom signs)

• You need to cut hardwoods or thick acrylic (10-18mm)

• You want faster production speeds

• You’re ready to invest $5K-$12K

✔ Choose a 150W+ Laser If:

• You do industrial fabrication

• You cut 20mm+ materials daily

• Speed is critical (large batches)

• Budget is not a concern ($15K+)

Final Verdict

• Hobbyists & Beginners → 40W (OMTech, K40)

• Small Businesses → 60W-100W (Thunder Nova, Boss LS-1630)

• Industrial Users → 150W+ (Boss LS-2440, Trotec)

Still unsure? Ask yourself:

1. What materials will I cut most?

2. How fast do I need to work?

3. What’s my budget?
