Spec Comparison: CO2 vs Fiber
Laser Type
The OMTech 90W CO2 Laser Engraver uses a CO2 laser tube, which is ideal for organic materials. It can engrave up to 0.4 inches deep on non-metallics. The OMTech 30W Fiber Laser Engraver uses a solid-state fiber laser source. This type is designed specifically for marking metals and plastics. The fiber source offers an average service life over 100,000 hours, which is significantly longer than the CO2 tube's 12,000-hour lifespan. You need to choose based on whether you work with wood or metal. CO2 is for non-metals. Fiber is for metals. This fundamental difference dictates your material choices.
Working Area
Size matters for project scale. The OMTech 90W CO2 Laser Engraver provides a generous 20 x 28 inch work area. It features a honeycomb work surface and supports large projects. You can even use pass-through doors for bulky items. In contrast, the OMTech 30W Fiber Laser Engraver has a much smaller 6.9 x 6.9 inch solid stage. This galvo system is precise but limited to small items like jewelry or serial numbers. If you need to engrave large boards or sign materials, the CO2 model is the clear choice. The fiber unit is strictly for small, detailed marks.
Engraving Speed
Speed varies by technology. The OMTech 90W CO2 Laser Engraver reaches engraving speeds of up to 600 mm/s. This is sufficient for cutting and engraving larger areas efficiently. The OMTech 30W Fiber Laser Engraver operates with a high-speed galvanometric system. It can achieve speeds of up to 10,000 mm/s. This extreme speed is beneficial for high-volume marking of small parts. The fiber laser scans the surface rapidly using mirrors. The CO2 laser moves a physical head. For quick ID tags, the fiber is faster. For larger cuts, the CO2 speed is adequate.
Software Compatibility
Both machines support LightBurn software, which is a major plus for users who prefer that interface. The OMTech 90W CO2 Laser Engraver comes with LightBurn included. The OMTech 30W Fiber Laser Engraver also supports LightBurn. However, the fiber model additionally includes EzCad2 software for Windows. EzCad2 is standard for many fiber marking applications. It supports various image formats and is often used for industrial marking tasks. If you need EzCad2, the fiber unit has an advantage. If you only use LightBurn, both are equal. You have options with the fiber model.
Build and Weight
The physical footprint differs greatly. The OMTech 90W CO2 Laser Engraver is a large machine. It weighs 227 pounds and measures 57.1 inches in length. It requires significant floor space, comparable to a washing machine. The OMTech 30W Fiber Laser Engraver is compact and portable. It weighs only 65 pounds. The fiber unit is designed for benchtop use. You can easily move it or store it. The CO2 model is a stationary workstation. Consider your workspace size. If you have limited room, the fiber laser is much easier to accommodate. The CO2 unit demands a dedicated area.
Choose Your OMTech Laser
Woodworkers needing large cuts
You need a 20 by 28 inch work area for big projects. This 90W CO2 unit handles non-metallics up to 0.4 inches deep. The 600 mm/s speed and 12,000 hour lifespan suit long sessions. Air assist and water cooling keep the lens clean and the tube cool for consistent results.
Jewelers marking small metal parts
You require precision on metals like gold or silver. The 30W fiber laser etches with high speed up to 10,000 mm/s. The 6.9 by 6.9 inch bed fits small items perfectly. The 100,000 hour laser life reduces maintenance. EzCad2 software supports various image formats for detailed logos.
Users prioritizing compact footprint
You have limited space and need a lighter machine. This fiber engraver weighs only 65 pounds. It is much smaller than the 227 pound CO2 alternative. The solid-state design offers durability without bulky tubes. You get fast marking speeds and precise optics in a small package for quick tasks.

Frequently asked questions
Can the OMTech 90W CO2 laser engrave metal?
No, this unit is designed for non-metallic materials. It uses a CO2 laser tube that works best on wood, acrylic, and leather. It cannot mark metals directly. If you need to engrave metal, you should choose the fiber laser option instead, as CO2 lasers lack the wavelength required for metal processing.
What is the maximum engraving depth for the 90W CO2 model?
The OMTech 90W CO2 Laser Engraver can engrave up to 0.4 inches deep. This depth capability makes it suitable for heavy-duty projects on organic materials. The higher power output allows for deeper cuts compared to lower wattage CO2 units, providing significant material removal for thick wood or acrylic pieces.
Does the 30W Fiber laser work on wood or acrylic?
No, the OMTech 30W Fiber Laser Engraver is not suitable for organic materials. It is specialized for metal and jewelry marking. The fiber laser technology targets metallic surfaces like aluminum, silver, and gold. It will not effectively engrave wood, plastic, or leather, making it a poor choice for general crafting.
How much floor space does the CO2 laser require?
The OMTech 90W CO2 Laser Engraver is a large unit measuring 57.1 inches in length, 34.3 inches in width, and 27.6 inches in height. It weighs 227 pounds. You need ample workshop space to accommodate its size. The fiber laser is much smaller and lighter, fitting easily on a bench.
Is LightBurn software included with both machines?
Yes, both the OMTech 90W CO2 and the 30W Fiber models support LightBurn software. This compatibility ensures a consistent user experience across both devices. LightBurn allows for precise vector and raster engraving. You can use the same design files and settings interface regardless of which laser type you choose for your projects.
Which machine is better for jewelry engraving?
The OMTech 30W Fiber Laser Engraver is the correct choice for jewelry. It is specifically designed for metal and jewelry marking on small items. The fiber laser provides high-speed, precise engraving on metals like gold and silver. The CO2 laser lacks the necessary power and wavelength for detailed metal work on small accessories.
