FAQ

1.What Materials Can Be Engraved Using ComMarker's B4 50W Fiber Laser Engraver?

The ComMarker B4 50W Fiber Laser Engraver is designed to handle a diverse range of materials, including metals, hard plastic, stone, leather, and more. This fiber laser engraver can also cut 0.7mm stainless steel, aluminum, brass, silver, and gold, making it a versatile tool for various applications.

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

The key difference between the B4 and B4 MOPA models lies in their laser parameters:

  • Q-Switch: Offers a non-adjustable pulse width with a frequency range of 20kHz – 100kHz, making it ideal for high-speed metal engraving.
  • JPT MOPA: Provides a wider pulse width range (1-500nm) and a frequency range of 1kHz – 4000kHz. This allows for better results on certain plastics and metals, including color marking on stainless steel and titanium, and high-precision engraving on plastic without burnt yellow color.

If your primary need is engraving metals quickly and deeply without the need for color engraving, the standard fiber laser engraver is a great choice. However, if your work involves detailed color marking, the MOPA option is superior.

3.How Long Does the Laser Source Last in B4 50W Fiber Laser Engraver?

The laser source in the B4 50W Fiber Laser Engraver has an impressive lifespan of over 100,000 hours, ensuring you get long-lasting, consistent performance.

4.What Software is Included with the B4 50W Fiber Laser Engraver?

The B4 50W Fiber Laser Engraver is bundled with EZCad software, known for its user-friendly interface and robust features. It is also compatible with LightBurn software (not included), giving you flexibility in choosing the software that best suits your needs.

5.How Large is the Work Area Provided by the B4 50W Fiber Laser Marker?

The B4 50W Fiber Laser Engraver offers a standard work area of 4.3×4.3 inches (110×110 mm) and 7.8×7.8 inches (200×200 mm). For projects requiring different field sizes, additional lenses from 70mm to 200mm can be ordered, allowing for greater versatility in handling projects of varying sizes.

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.

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.

One of the best values for a fiber laser!

The B4 50W Q-switched laser strikes an excellent balance between performance and cost.

At first I was concerned that it used a MAX laser source since a lot of people recommend avoiding MAX. Since the price was very good, I looked for the primary reason behind the lower recommendations and found that it was due to the historically low frequency range of the MAX Q-switched lasers compared to other Q-switched lasers. When I looked at the specifications on the ComMarker site they didn’t seem to match the specifications from older reviews I had read. I asked ComMarker for the specific model number and they provided me with a sample copy of a test report that gave me the model number and tested specifications. It turns out they are using a newer model of the laser module and I was able to verify the specifications from the MAX website and another MAX distributor website. It is a better version than their older models and is now more comparable to its competitors. For those curious I’ve attached a picture of my test report.

With that settled, I pulled the trigger and ordered it. Just after I ordered the chaos of the tariff changes began. I contacted ComMarker and they assured me they would be able to fulfill the order at the price I paid and that taxes and duties would be included.

Once it shipped I received it from overseas about three days later. Everything was packed well and arrived in perfect condition. Between the assembly video and manual they provided I was able to get the laser setup quickly and perform some initial tests.

I ended up deciding to build an enclosure so that I could customize it to suit my needs and fit my work space. I look forward to using the B4 more often once I am able finish the enclosure and ventilation system and would definitely purchase from ComMarker again, with the Omni 1 being high on my list.

Professional Laser

Needing a laser to enhance my CNC business, after extensive research, the Commarker range hit the mark from support to range. Ultimately opting for the B4 50w to compliment the metal work I do.
I have not been disappointed and the support from Commarker when approached has been brilliant.

ComMarker B4 50W Fiber Laser Engraver

Received unit well packed and undamaged. Unit was a little difficult to setup on an Apple Mac computer, but is now working. ComMarker technical support was quick to respond to my questions, Now just beginning to learn how to use and what all it can do with the laser. Have made several successful engravings so far.
