- You need a larger working area of 300 x 300 mm for bigger parts.
- You want to perform color marking on stainless steel or deep engraving on metals.
Verdict: Choose the SFX 30W CO2 Galvo Engraver if your projects involve wood, acrylic, and other non-metals. Select the SFX 100W MOPA Fiber Laser if you need to mark metals, require a larger workspace, or want advanced pulse control for detailed metalwork.
SFX 30W CO2 vs 100W MOPA Fiber
Laser Type
The SFX 30W CO2 Galvo Engraver uses a CO2 DAVI laser source. This technology relies on a gas mixture to generate light, making it ideal for organic materials. In contrast, the SFX 100W MOPA Fiber Laser uses a JPT M7+ fiber source. Fiber lasers use doped glass fibers to amplify light. This fundamental difference dictates what each machine can mark. CO2 lasers interact differently with materials than fiber lasers. You must choose based on whether you need to mark plastics and wood or metals.
Laser Power
Power ratings show the energy output capability of each machine. The SFX 30W CO2 Galvo Engraver operates at 30W. This lower power is sufficient for deep engraving on non-metals, with a depth range of 0.01mm to 2mm. The SFX 100W MOPA Fiber Laser offers 100W. This higher power allows for faster marking speeds and deeper cuts on metals. The 100W unit can also handle material thicknesses up to 250mm. Higher wattage generally means quicker processing for industrial applications.
Compatible Material
Material compatibility is the most critical selection factor. The SFX 30W CO2 Galvo Engraver is suitable for wood, glass, acrylic, paper, rubber, and other non-metallic materials. It is not designed for bare metals. The SFX 100W MOPA Fiber Laser works on all metals, including aluminum, stainless steel, brass, and copper. It can also mark some non-metals like nylon, ABS, and PVC. If you need to mark metal, the CO2 unit will not work. If you only mark plastics, the fiber unit is overkill.
Working Area
The marking area determines the size of objects you can process. The SFX 30W CO2 Galvo Engraver has a lens area of 140x140mm. This smaller footprint is good for small components like ICs or phone parts. The SFX 100W MOPA Fiber Laser provides a larger marking area of 300x300mm. This allows you to engrave larger metal plates or multiple items at once. The larger area offers more flexibility for bigger projects, while the smaller area is precise for tiny details.
Pulse Control
Pulse control affects the quality of the mark. The SFX 100W MOPA Fiber Laser features a MOPA source with a repetition rate of 1-4000kHz and pulse duration of 2-500ns. This allows for color marking on stainless steel and stripping anode layers from aluminum. The SFX 30W CO2 Galvo Engraver does not list pulse frequency or duration specs. CO2 lasers typically operate differently. The MOPA capability gives you advanced control over metal marking aesthetics, which the CO2 unit cannot match.
Software Compatibility
Software determines how you design and send marks. The SFX 100W MOPA Fiber Laser uses EZCAD software. It is compatible with Windows XP, Vista, 7, 8, and 10. This ensures broad operating system support for standard design tools. The SFX 30W CO2 Galvo Engraver does not list specific software in the provided data. While it likely uses similar marking software, the lack of explicit details makes the fiber unit's compatibility clearer. You should verify the CO2 software requirements separately.
Which Laser Engraver Suits Your Needs?
You mark wood, glass, acrylic, or rubber items.
Choose the SFX 30W CO2 Galvo Engraver for non-metallic materials. It features a 140 x 140 mm working area and a 30W CO2 DAVI laser source. The included D80 rotary axis allows you to engrave cylindrical objects. This machine is suitable for food, medicine, and electronics industries. It offers an engraving depth between 0.01mm and 2mm for detailed work on organic surfaces.
You need to mark metals like steel or aluminum.
Pick the SFX 100W MOPA Fiber Laser for metal applications. It uses a JPT M7+ MOPA fiber source with a 100W power output. The 300 x 300 mm marking area is larger than the CO2 model. It supports pulse durations from 2 to 500ns and frequencies up to 4000kHz. This setup enables color marking on stainless steel and stripping anode layers from aluminum oxide plates.
You require a larger workspace for bigger projects.
The SFX 100W MOPA Fiber Laser provides a 300 x 300 mm marking area. This is significantly larger than the 140 x 140 mm area of the CO2 model. The larger footprint allows you to process bigger metal or non-metal parts without repositioning. It also includes an 80mm rotary device. The machine runs on EZCAD software and is compatible with various Windows operating systems for stable performance.
