Is the ComMarker Titan 100W MOPA the Best Laser Engraver for Deep Metal Work?

A Real-World Look at the ComMarker Titan 100W MOPA Fiber Laser Engraver

When ComMarker reached out and offered to let me test their Titan 100W MOPA fiber laser engraver, I was immediately intrigued. I’ve worked with a range of diode and fiber machines over the years, but the specs on this one hinted at something built for serious work—think obliterating metal, engraving 3D surfaces, and creating durable color markings. Spoiler alert: it didn’t disappoint.

Unboxing the Titan: What You Get

First impressions? The Titan comes in what I’d call full-on retail packaging—neat, secure, and organized. Here’s what I found in the box:

Certified laser safety goggles
Foot switch (thank you!)
Material test kit
All necessary screws and tools
Electric Z-axis gantry system
Cooling system
A solid 300×300 mm workspace
Dual lenses (110×110 and 200×200 optional)
Compatible with EZCAD & LightBurn

Assembly was straightforward—rubber feet on the base, gantry bolted to the frame, data and power cables hooked up, and everything just worked.

Recommended: If you’re new to fiber lasers but want industrial-grade results, the Titan is plug-and-play and feels intuitive. Check it out on the ComMarker official site.

Key Features: Power Meets Precision

The Titan 100W MOPA fiber laser engraver is designed for non-stop production. With up to 200W options available, I tested the 100W model which boasts:

Speeds up to 15,000 mm/s
Powered Z-lift for easy focus
Support for super 3D engraving and color marking
Dual-lens setup for variable work sizes
Excellent accuracy (HD-level detail)

The motorized Z-axis uses a dot alignment system, and when using the 110×110 lens, you’re looking at a focal length of around 279 mm. Switching to the 200×200 lens? Adjust to 426 mm.

Let’s Engrave: Deep Relief 3D Coin Test

This machine is no toy. I ran a 3D coin engraving as a real-world stress test.

Settings used:

Speed: 3200 mm/s
Frequency: 80
Max Power: 90%
Q Pulse: 200
Line Interval: 0.016
Passes: 512
Cleanup every 5 passes
Final cleanup pass: 6000 mm/s, 30% power, 0.1 interval

Result?
Over 2 hours of work and we were nearly through the coin—it was that deep. Details were crisp, textured, and tactile. This machine absolutely chews through metal. Honestly, I should’ve dialed back the power a bit!

Pro tip: Always test on scrap before committing to full power. View the full Titan 1 details here.

Color Marking: The Magic of MOPA

Next up: a color biohazard symbol test.

I used pink, blue, and “orchid” settings:

Speeds: 500–960 mm/s
Frequency: 100–325
Power: 11–33%
Pulse width & line intervals varied by shade

What I learned: even tiny Z-height changes affect color dramatically. One small adjustment and the “orchid” turned blue. So, when color matters, consistency is everything.

This laser engraver gives you stunning color flexibility—but expect a learning curve.

Plastic Engraving & Rust Removal

Tried engraving a white plastic MacBook charger next:

Speed: 2500 mm/s
Frequency: 50
Power: 20%
Clean, sharp lines and no burn smell (thanks to good ventilation)

Also cleaned up a rusty Stanley hammer using:

Speed: 3500 mm/s
Frequency: 20
Power: 80%
Results? Practically new. Surface rust vaporized with no grinding needed.

Whether you’re branding tools or cleaning them, the Titan gets the job done clean and fast.

Mistakes I Made (So You Don’t Have To)

Overpowering on coins: Burned right through and scorched my bed. Rookie move. Keep a ceramic tile or coaster underneath during deep work.
Improper ventilation layout: Placed the split unit too close to the engraving area. Result? Metal particulates gunked up the intake.
Color inconsistencies: Z-height changes really impact color outcomes. Always test first.

Dog Tags = Easy Money

Laser-engraved dog tags are fast, fun, and profitable:

Settings: 1500 mm/s, 75 frequency, 50% power
Engraved and cleaned in under 2 minutes
QR code test = success

I could easily see someone starting a side hustle making tags for pets, sports teams, or events.
