The Other Laser Cutter: Why I Chose the xTool M1 Ultra (And What It Can’t Do)

After comparing 6 different laser engravers over 3 months for our workshop, I picked the xTool M1 Ultra. But here's the thing: it's a fantastic machine for a very specific use case, and it's not the right fit for everyone. If you're looking for a laser that can cut thick hardwood or metal, keep looking. But if you need a versatile, 4-in-1 system for small-batch production and prototyping, this might be your best bet.

I'm a procurement manager. My job is to get the most value for our budget without getting burned by hidden costs or equipment that doesn't deliver. Over the past 5 years, I've managed around $150,000 in annual equipment spending. I've learned (the hard way) that the cheapest option or the one that claims to do everything is rarely the best. That's why I built a total cost of ownership (TCO) spreadsheet before making this decision.

What Makes the M1 Ultra Different?

The M1 Ultra is a 4-in-1 machine: a diode laser for cutting and engraving, a blade cutter, a rotary tool, and a print-then-cut module. The headline feature is that it can handle a wider range of materials than most desktop lasers. I've successfully cut 3mm basswood and 5mm acrylic, and engraved on everything from anodized aluminum to slate coasters (granite laser engraving is a real possibility).

But the real surprise was the blade cutting module. I'd written it off as a gimmick. Then I needed to prototype a small run of custom shaped leather keychains. The laser would have charred the edges. The blade cutter? Perfect, clean cuts. Never expected the 'bonus' feature to be the game-changer.

The Laser Type: A Note of Caution

The M1 Ultra uses a high-power diode laser (around 20W optical output). This is not a CO2 laser, and it's not a fiber laser. Let me save you a mistake I almost made: do not buy this expecting to cut 10mm acrylic or any thickness of metal. It's not designed for that.

For engraving, it's excellent. For cutting, it's best on thin materials (under 5mm wood, under 3mm acrylic for a clean pass). I've seen some users claim to cut thicker materials with multiple passes, but in my experience, the quality degrades significantly. It's faster and cleaner to use a CO2 laser for those jobs.

xTool M1 Ultra Laser Type: 20W Diode. Wavelength: 455nm. Wavelength matters because it affects how different materials absorb the laser energy. Dark materials engrave better than light ones. This is physics, not a flaw.

Acrylic Cutting: The Sweet Spot

For xTool M1 Ultra cut acrylic performance, I tested 3mm cast acrylic. The settings I found reliable: power 80%, speed 15mm/s, 1 pass. The result: a flame-polished edge, slightly frosted. Not as perfectly clear as a CO2 laser cut, but clean and functional. For 5mm acrylic, I needed 2 passes and the edges were less clean. For thicker than that, I'd send the job out to a local shop. This was accurate as of Q1 2025. Material formulations change, so test your own settings.

Laser Engraving Settings: My Go-To Starting Points

Every material is different, but here's where I start. These are baseline settings, not guarantees.

• Basswood: 100% power, 300mm/min, 0.05mm per pass for deep engraving.
• Acrylic: 60% power, 600mm/min for a crisp, contrasting mark.
• Anodized Aluminum: 100% power, 300mm/min. The laser burns away the anodized layer, leaving a white mark.
• Slate: 80% power, 400mm/min. Produces a clean, high-contrast white mark.

I always run a test grid on a scrap piece of the material before committing to a final job. Fire-and-forget settings are a myth (note to self: remind the production team of this monthly).

The Cost: Not Just the Upfront Price

The xTool M1 Ultra is not cheap. The base machine is around $1,800. With the rotary tool, blade cutter module, and a few materials, my total was just over $2,500. That's a significant investment for a small shop. But when I compared this to buying a separate CO2 laser (for wood and acrylic) and a separate blade cutter (for fabric and leather), the M1 Ultra came out ahead on TCO. One machine, one footprint, one learning curve. That has real value.

The surprise wasn't the price, though. It was the consumables. Exhaust filters, lens cleaning kits, and replacement blades add up. I budget about $200 per year for maintenance items. Not a deal-breaker, but something to factor in.

What is laser cut? In simple terms, a laser cutter uses a high-power laser beam to burn, melt, or vaporize material along a programmed path. The M1 Ultra's diode laser is great for this on thin, non-metallic materials.

What It's Not Good At (My Honest Take)

I want to be clear about the limitations because ignoring them is how you end up with wasted material and a frustrated team. The M1 Ultra is not for:

• High-volume production. The work area is small (about 17x12 inches). For batch work, a CO2 laser with a larger bed is much faster.
• Cutting metals. A diode laser can mark coated metals but cannot cut them. A fiber laser or CNC plasma is required for that.
• Thick materials. Anything over 5mm is a struggle. Multiple passes are possible but rarely worth the time and quality loss.

The vendor who says 'this isn't our strength' earns my trust. xTool is transparent about these limits, which is why I felt comfortable making the purchase. They'll tell you that for cutting thick wood or metal, you should look elsewhere. I appreciate that honesty.

Final Verdict

The xTool M1 Ultra is a versatile, well-built machine for the right user. For a small business, a maker space, or a prototyping shop, it can replace three separate devices. But if you primarily need to cut thick materials or do high-volume work, it's the wrong tool. Know your boundaries, and you won't be disappointed.
