FAQ

1.What Materials Can Be Engraved Using ComMarker's B4 30W Fiber Laser Engraver Machine?

The ComMarker B4 30W Fiber Laser Engraver Machine is versatile, capable of engraving a wide range of materials, including metals, hard plastics, stone, leather, and more. This adaptability makes it a powerful tool for various industries, providing high-quality results with precision.

2.What's the Difference Between B4 and B4 MOPA?

The main difference between the B4 and B4 MOPA models lies in their laser technology:

  • Q-Switch: Features a non-adjustable pulse width, with a frequency range of 20kHz – 100kHz. This is suitable for high-speed engraving on metals without color variations.
  • JPT MOPA: Offers a pulse width of 1-500nm and a frequency range of 1kHz – 4000kHz. The MOPA laser is superior for engraving colors on stainless steel, titanium, black on aluminum, and plastic without burnt yellow color, providing greater accuracy.

The B4 MOPA is ideal if you require color marking on metals and high precision, while the standard fiber laser is better suited for straightforward, high-speed metal engraving. Price and work effect vary significantly between the two models.

3.How Long Does the Laser Source Last in B4 30W Fiber Laser Engraver Machine?

The laser source in the B4 30W Fiber Laser Engraver Machine has a lifespan of over 100,000 hours, ensuring reliable, long-lasting performance.

4.What Software is Included with the B4 30W Fiber Laser Engraver?

The B4 30W Fiber Laser Engraver comes with EZCad software and is compatible with LightBurn software (not included). This provides a comprehensive suite of tools for managing engraving projects efficiently.

5.How Large is the Work Area Provided by the B4 30W Fiber Laser Marker?

The B4 30W provides a 4.3×4.3 inch (110×110 mm) and 7.8×7.8 inch (200×200 mm) field for various project sizes. Additional lenses ranging from 70mm to 200mm are available upon request to accommodate different engraving needs.

Fantastic service and great product

The machine arrived very fast in less than a month. Only inconvenience was that I had to pay additional duty when arriving to Malaysia. I engrave on a lot of metal, so this machine is very suitable. Able to engrave on any surface. It is also capable of cutting through aluminum easily. They provided all necessary manuals and guides to quickly get started. It was a smooth experience for me. Highly recommended.

We received our safety enclosure, but the top was damaged during shipping. I contacted their support, and it was handled immediately. We received a new top replacement piece and it's all working great.

Satisfaction

Originally, I had a 20W diode laser.
Then I decided to purchase a ComMarker MOPA 60W.
Encouraged by the easy purchase process and the usability of the IR engraver, I also bought a 5W Omni1. I haven’t tested all of its features yet, but everything I have tried so far has worked flawlessly. I can recommend these models to any DIY enthusiast.

One Laser to Do It All in 2025? The OMNI1 Might Be It

I started laser engraving back in 2021, and the progress in just a few years has been incredible. Prices have dropped, and high-end laser technology that used to be out of reach for small businesses and hobbyists is now more accessible than ever. When I first got started, you needed multiple lasers to cover different materials. But in 2025, with just one or two machines, you can handle almost anything you want to engrave. The OMNI1 UV laser is a game-changer. It covers such a wide range of materials that for many people, it could be the only laser they ever need. One of my dream capabilities was glass engraving — and this UV laser not only handles glass beautifully but also delivers stunning high-definition images that truly blew me away.

Very impressed

You know you have a good laser when you cant think of a single bad thing to say about it. Ive enjoyed the increased speed, power and potential. I also got the D80 rotary and thats one solid piece of machinery, also easy to use. I recommend this laser.
