When it comes to choosing a CO2 laser engraver, one of the most crucial decisions you'll face is selecting the right power level for your projects. Two popular choices in the desktop market are the 40W and 70W CO2 laser engraver models. Each offers distinct advantages depending on your material type, workload, and business goals. In this blog, we’ll compare the 40W vs 70W CO2 laser engraver options, focusing on two standout machines from Monport—the 40W Pro desktop laser engraver and the Monport Mega 70W CO2 desktop laser cutter, the world’s premier intelligent desktop CO2 laser engraver.

1. Power Output & Cutting Capability
Power matters, especially when you're dealing with tougher materials or bulk engraving tasks. A 40W CO2 laser is excellent for light-duty projects like cutting thin wood, acrylic, or leather. It offers precise engraving with clean, shallow cuts.
On the other hand, the 70W CO2 laser engraver, like the Monport Mega, delivers nearly double the power. This means deeper cuts, faster processing, and a broader range of materials. With the ability to cut up to 25mm thick wood or acrylic, the 70W option is ideal for professionals or businesses needing production-level performance.

2. Speed and Efficiency
Speed is another major factor when comparing 40W vs 70W CO2 laser engraver machines. The Monport 40W Pro maxes out at 350mm/s, making it efficient for hobbyists and small-scale businesses.
However, the Monport Mega 70W truly shines here with a maximum working speed of 600mm/s. Whether you’re engraving intricate designs or cutting through thick materials, the Mega is built for high-speed output without compromising quality.
💡 If you're running a small production shop or need to fulfill frequent custom orders, investing in a faster desktop CO2 laser engraver can drastically improve turnaround time.
