CO2 laser engravers are versatile tools for hobbyists, small businesses, and makers. But with varying power levels and price points, is a 40W model the right choice? In this review, we’ll break down its performance, best uses, and whether it’s worth buying over higher-powered alternatives.
Power & Speed
A 40W laser is ideal for engraving wood, acrylic, leather, and some plastics.
Can cut thin materials (3-5mm wood/acrylic) but struggles with thicker stock.
Slower than 60W+ lasers but more affordable.
Work Area & Compatibility
Common bed sizes: 300x200mm to 600x900mm (desktop to mid-size).
Works with LightBurn, RDWorks, and other laser software.
Cooling & Maintenance
Requires air assist for cleaner cuts.
Water cooling (or air-cooled tubes) needs regular checks.
✅ Pros:
Lower upfront cost than 60W+ lasers.
Good for detailed engraving (jewelry, signage, crafts).
Energy-efficient for small workshops.
❌ Cons:
Limited cutting ability (not for thick metals or dense materials).
Slower than high-power lasers for production work.
✔ Hobbyists & Small Businesses – Great for custom gifts, wood engraving, and acrylic art.
✔ Beginners – Lower cost reduces risk if you’re new to laser cutting.
✔ Low-Volume Makers – If you don’t need heavy-duty cutting, this is a budget-friendly pick.
Avoid if: You need to cut thick materials or run high-speed production.
60W-100W CO2 Lasers – Faster cutting, better for businesses.
Diode Lasers – Cheaper but weaker (best for thin materials only).
Fiber Lasers – For metal engraving (but much more expensive).
If you need an affordable, entry-level laser for engraving and light cutting, the 40W CO2 laser is a solid choice. However, for thicker materials or fast production, consider upgrading to 60W or higher.
OMTech 40W (budget-friendly)
