In March 2024, at 7:30 a.m., our personalization shop received a text: 40 brass plaques needed by Thursday. Normal lead time for engraved brass is five business days. This order had two days, and a penalty clause big enough that missing it would have hurt. We didn't panic. We used an xTool S1 with the 1064nm infrared laser module.
I'm the production lead at a small awards and personalization shop. In six years, I've handled 200-plus rush orders, including same-day turnarounds for event gift boxes and custom plaques. This isn't a spec-sheet review. It's what I learned after one $450 mistake, one $900 rush fee, and a lot of wasted time.
The Surface Problem: You Want a Small Laser Cutter for Metal
If you're searching for a 'small laser cutter for metal' or a 'mini laser cutter,' you know the pain: a desktop machine that cuts wood and engraves metal sounds ideal. Then you read the fine print. Some lasers only work on coated steel. Some need marking spray. Some can't touch bare aluminum. It's tempting to think all laser engravers are basically the same and only power matters. That's the oversimplification that caused our $450 mistake.
The 'higher wattage means more metal' advice ignores the one thing that matters most: wavelength.
The Hidden Problem: Wavelength, Not Wattage
A laser doesn't process metal because it's 'hot.' It transfers energy based on how the material absorbs a specific wavelength. A blue diode laser (455nm) is absorbed well by wood, dark acrylic, leather, and many plastics. Bare metal reflects most of it. A CO2 laser at 10.6µm is absorbed by acrylic, leather, glass, and organic materials, but it's not a practical way to engrave bare metal. Fiber lasers at 1064nm caught on because their wavelength, pulse energy, and focused spot interact differently with metal surfaces.
Here's something vendors won't tell you: rated power matters less than wavelength and focal-spot quality. You can run a 100W CO2 laser and still not mark bare aluminum the way a small 1064nm marker does. You can't solve wavelength with wattage.
Wavelength wins over wattage.
Five years ago, if you wanted a 1064nm metal engraver, you were looking at a fiber laser in a large cabinet, often with a four-figure price tag. Now you can swap an infrared module into a desktop system like the xTool S1. It isn't an industrial fiber laser, but it changes what a small shop can do in a week.
I have mixed feelings about the phrase 'metal engraving diode laser.' On one hand, this kind of module is a practical tool that brought metal marking into our shop. On the other, the phrase sets up unrealistic expectations. A 1064nm module will mark metal. It won't slice through 3mm steel plate.
The Real Cost of Getting This Wrong
The price of a wrong laser cutter isn't the machine. It's the project you miss.
Last March, a client called at 9 a.m. needing 60 stainless steel tags for a conference two days later. We had bought a mini laser cutter the year before hoping to handle jobs like this. It failed on bare steel. We outsourced to a local fiber shop; the rush fee was $900. We delivered, but the margin disappeared. If we had owned a proper tool from the start, the job would have stayed in-house.
Then there's the slower bleed: test materials, marking sprays, failed runs, and the hours spent troubleshooting a machine that was never physically able to do the job. A cheap engraver that can't hold a consistent mark is more expensive than a good one that can.
What Actually Works: xTool S1 and the 1064nm Infrared Module
In our shop, the xTool S1 is now the workhorse for quick-turn custom parts. Not because it's the 'best' laser ever made, but because it balances price, accessories, and interchangeable modules.
xTool S1 Laser Cutter Price: What You Actually Pay
According to xTool's official store (xtool.com, as of January 2025), the S1 20W starts around $1,200 and the 40W around $2,000. Add the 1064nm infrared laser module and practical accessories like air assist or the rotary bundle, and a full kit lands near $2,500–$3,000. That's still less than a starter fiber engraver, which often costs $4,000–$8,000 based on vendor quotes from January 2025. Prices change, so verify current rates.
Using the 1064nm Module for Metal
Using the xTool S1 1064nm infrared laser module, we've engraved stainless steel tags, anodized aluminum, gold-plated keychains, and copper parts. We don't use marking spray for most of these. We do use a test matrix because settings vary with alloy and finish. Focus, speed, power, and cleanliness are still part of the operator's job. For metal jobs, we clean the part with alcohol, set focus with the S1's focus tool, and run a small matrix before committing to the full batch.
How to Laser Engrave Clear Acrylic Without Melting Everything
This phrase took us months to figure out because the standard advice is written for CO2 lasers. The short answer for the xTool S1:
- Use cast acrylic, not extruded. Cast produces a frosty white mark. Extruded tends to melt and becomes cloudy.
- Use the 1064nm infrared module for clear acrylic. The blue diode is great for wood and dark material, but it often passes through clear acrylic or leaves a weak mark.
- Set focus carefully with the included tool or a test piece.
- Run a speed/power matrix before the full job. On 3mm clear cast acrylic, a reasonable starting point is around 1500mm/min and 40-70% power, then adjust for contrast.
- Keep the enclosure closed and use ventilation. 1064nm is invisible and can damage your eyes quickly.
There is something satisfying about watching a clear sheet turn into a sharp frosted mark with the same machine that engraved metal earlier that day. If your main product is large-format acrylic signs, a CO2 system is still a stronger option. But for mixed-material rush jobs, the S1 with the IR module is flexible.
Bottom Line
The phrase 'small laser cutter for metal' is misleading. The xTool S1 is best understood as a compact laser engraver/cutter that handles metal engraving when equipped with the 1064nm infrared module. It is not a steel cutter and not a fiber replacement. It is a desktop tool that lets a busy shop keep projects in-house.
Before you buy, ignore the wattage arms race. Match the wavelength to the material, run test pieces, keep a 48-hour buffer, and verify current pricing. The fundamentals haven't changed, but the execution has.
