Can the xTool S1 Cut Metal? A Procurement Manager's Honest Cost Breakdown

If you're running a small workshop and looking at the xTool S1, you've probably asked this exact question. I'm a procurement manager for a 15-person custom fabrication company. I've managed our equipment and consumables budget (around $180,000 annually) for six years, and I've learned the hard way that the cheapest upfront option often costs more in the long run. Let's cut through the marketing and talk real costs and capabilities.

Your Top Questions on the xTool S1 and Metal, Answered

1. Can the xTool S1 actually cut through metal?

Straight answer: No, not for cutting out shapes. Don't let anyone tell you otherwise. I've compared quotes and specs for everything from desktop units to 6kW industrial lasers. The xTool S1's 20W or 40W diode laser modules simply don't have the power density to vaporize a path through sheet metal like a fiber laser or plasma cutter can.

What it can do is engrave certain metals. We're talking about marking surfaces—creating designs, serial numbers, or logos on coated metals, anodized aluminum, stainless steel with a marking spray, or brass. It's for decoration and identification, not fabrication. I learned this distinction after almost approving a purchase for a part we needed to cut, not mark. That misassumption would've cost us time and a return fee.

2. So, what's the deal with the "IR Laser" module? Is that for metal?

This is the key upgrade. The standard blue-light diode lasers struggle with reflective surfaces. The optional infrared (IR) laser module is much better suited for direct marking on bare metals like stainless steel, titanium, and some alloys. It's a game-changer for engraving, but again, not for cutting.

Here's the cost controller perspective: that IR module isn't free. When I built our TCO (Total Cost of Ownership) spreadsheet for this machine, I didn't just look at the base price. The IR module is an added investment. If metal engraving is your primary goal, you need to factor that into your initial budget, or you'll be stuck with a machine that can't do the job you bought it for.

3. How does it compare to a plasma cutter for something like aluminum?

This is an apples-to-oranges comparison, and it's one I see beginners make all the time. A plasma cutter is for cutting and profiling metal sheets—it's a fabrication tool. The xTool S1 is for engraving and marking flat or cylindrical objects.

Let me put it this way: if you need to make 50 aluminum brackets, you use a plasma cutter or a CNC router. If you need to put part numbers and your logo on those 50 finished brackets, then you might use an engraver like the S1. They're complementary tools in a shop, not replacements for each other. Assuming one could do the other's job is a fast track to project delays and wasted material.

4. Is the rotary attachment worth it for metal parts?

If you engrave cylindrical metal items—pens, tumblers, flashlight barrels, tool handles—then absolutely, it's not just worth it, it's essential. Trying to manually rotate an item for a seamless engraving is a recipe for inconsistency and ruined workpieces.

From a cost standpoint, consider the volume. The rotary attachment is another add-on. I'd only justify it if you have steady, paid work for cylindrical engraving. Otherwise, it's capital sitting on a shelf. For our shop, we ran the numbers: we'd need to engrave about 30-40 custom water bottles per month to see a ROI within a year on that attachment alone. We didn't have the orders, so we held off.

5. What are the hidden costs of running an xTool S1 for metal engraving?

This is where my procurement brain kicks in. The sticker price is just the start.

• Consumables for Metal: You'll go through marking sprays (like Cermark or LaserBond) for certain metals. These aren't wildly expensive, but they're a recurring cost per job that eats into your margin.
• Time & Setup: Dialing in the right power/speed settings for different metals takes time. That's labor cost. A failed test on a customer's part is a material cost.
• Ventilation & Safety: Engraving metals, especially with coatings, produces fumes. Proper ventilation isn't optional; it's a health requirement and another equipment cost.
• Maintenance: Lenses get dirty faster when working with sprays. Cleaning kits and eventual lens replacement are part of the long-term TCO.

I've seen shops buy a "cheap" machine only to spend hundreds more making it work for their specific need. Factor it all in upfront.

6. Would you, as a cost controller, approve this purchase for a small shop?

It depends entirely on the work mix. Here's my decision framework:

Approve it if: Your business already handles a lot of personalized wood, acrylic, leather, and coated tumblers, and you're getting consistent requests for adding metal engraving (dog tags, tool marking, small awards). The S1 is a versatile desktop expander. The modularity is a genuine advantage—you can start with the basic head and add the IR later when you have the metal work to justify it.

Reject it if: You're a metal fabrication shop looking for a way to cut small parts or primarily work with raw, thick steel. You'd be buying the wrong tool. You'd be better off leasing time on an industrial fiber laser or partnering with a shop that has one until your volume justifies that tier of equipment. I've vetoed purchases where the core need was clearly misaligned with the tool's capability. Saving $5,000 on the wrong machine costs you $15,000 in lost opportunity and rework.

My final take? The xTool S1 is a capable engraver that can mark metals with the right setup. It's not a metal cutter. Be brutally honest about your primary use cases, build a realistic TCO model that includes all modules and consumables you'll need, and don't expect an industrial result from a desktop machine. That's how you make a purchase that saves money over time, instead of becoming a regret gathering dust in the corner.
