Why the Mega 70W CO2 Laser Stands Out
The Monport Mega CO2 Laser is designed to serve professional users and high-output makers who need more speed, space, and smart automation.
Greater Power and Speed
With a 70W CO2 laser, Mega delivers faster cutting and deeper engraving capabilities. It easily handles demanding materials like thick wood or colored acrylic in a single pass. Its 1000mm/s speed is double that of the Onyx 55W CO2 Laser, which significantly boosts productivity for businesses.
Larger Engraving Area
The Mega’s expansive 27.56" x 13.78" work area allows for larger designs, batch processing, or multiple smaller items engraved simultaneously. This makes it ideal for high-volume production environments.
Intelligent Vision and Autofocus Features
The integrated ultra-wide 8MP camera and visual path alignment system allow batch engraving with high accuracy. Combined with automatic height adjustment and autofocus, setup takes less than five minutes—saving valuable time compared to manual adjustments.
Industrial-Grade Safety and Reliability
Advanced features like flame detection, enclosed guide rails, and fire extinguishing systems offer superior safety, especially in commercial or educational environments. The machine complies with Class 1 laser safety standards.
Why Choose the Onyx 55W CO2 Laser?
While not as powerful as the Mega, the Onyx 55W CO2 Laser remains a strong option for creators who prioritize a compact size, affordability, and ease of use.
Simple Setup and Operation
The Onyx’s one-touch autofocus system and user-friendly design make it ideal for new users or smaller workshops. The integrated 5MP camera provides a clear preview for design placement and resizing in LightBurn.
Fine Detail and Accuracy
Despite the lower laser wattage, the Onyx offers high engraving precision at 0.001” and supports a wide variety of materials, from leather to coated aluminum. It delivers clean cuts and sharp detail on designs under 18 inches wide.
Safer, Cleaner Workspace
Its enclosed housing and smoke extraction system ensure safer indoor operation. An emergency stop and cover sensors provide additional layers of protection.
Why the Mega CO2 Laser Is Ideal for Small Business Owners
For small business owners in engraving, personalization, or prototyping industries, choosing the right CO2 laser engraver can directly impact your turnaround time, customer satisfaction, and revenue growth. Between the Mega CO2 Laser and the Onyx 55W CO2 Laser, the Mega is the more strategic investment for growing operations.
Scale Production with Speed and Precision
Small businesses often face tight deadlines and fluctuating order volumes. The Mega 70W CO2 Laser empowers you to handle large or batch orders efficiently with its 1000mm/s max speed, expansive 27.56" x 13.78" work area, and autofocus system. This reduces setup time and boosts productivity—even with custom orders.
Reduce Labor and Setup Costs
Its smart tech features like visual light path alignment, auto-focus, and an intelligent touchscreen interface simplify training and operation. Whether you’re a one-person shop or scaling up with a small team, the Mega’s intuitive system helps reduce labor time while ensuring consistent, high-quality output.
Offer Premium Products and Services
The Mega’s 70W laser power, high engraving accuracy, and support for curved or multi-layered materials allow small businesses to offer more advanced and higher-margin services. From intricate signage to branded merchandise and personalized gifts, the machine enables creative flexibility to serve diverse markets.
Built-In Safety = Peace of Mind
Many small business workshops are based in garages, basements, or shared maker spaces. The Mega’s enclosed rail design, smoke exhaust system, and fire suppression technology make it one of the safest CO2 laser cutters in its class—ideal for home-based businesses or educational spaces.
