These are the questions I actually answer when a client calls with a photo of a material and a deadline that's already tight. I coordinate rush orders at a small laser fabrication studio, and since March 2024 we've pushed more than 200 jobs through our xTool F1 Ultra — many of them same-day turnarounds for event vendors, product designers, and small manufacturers.
What we're covering:
- What machine can cut acrylic?
- xTool F1 Ultra acrylic cutting settings
- Can the xTool F1 Ultra cut metal?
- Custom laser engraving on wood: how to get it clean
- Materials you shouldn't put in a laser
- Is a laser cutter service worth it?

What machine can cut acrylic?
Short answer: at the small-shop scale, a laser with a CO2 tube or a high-power diode module. We run the xTool F1 Ultra because its 20W diode laser cuts acrylic while the 20W fiber laser handles metals — basically two machines in one footprint.
But "cut acrylic" deserves nuance. Extruded acrylic cuts beautifully: clean edges, minimal chipping. Cast acrylic is more demanding — it can stress-crack mid-run and leaves a frosted edge. And clear transparent acrylic catches people off guard: a blue diode beam passes straight through it. That's where the fiber laser earns its keep, because 1064nm light interacts with transparent materials that the diode can't grip well.
One more thing: verify the sheet is actually acrylic. Polycarbonate, PVC, and ABS behave nothing like acrylic, and a couple of them release toxic fumes under a laser. If the material has no label and no data sheet, my rule is test a corner or don't run it.
xTool F1 Ultra acrylic cutting settings
Here are the starting points we settled on after 200+ acrylic jobs. Treat them as a baseline — batch differences happen, so always verify on scrap first.
For 3mm extruded acrylic (black or colored):
- Speed: 8–12 mm/s
- Power: 85–95%
- Air assist: on, max flow
- Passes: 1, sometimes 2 for a cleaner edge
For 5mm, drop to 4–6 mm/s and expect a second pass. Set the diode focus so the beam sits near the middle of the material thickness, and watch the edge color on the first few centimeters. A yellowish edge is a sign power is too high, not that speed is too low.
Clear acrylic gets its own profile. Last quarter, a client needed 40 transparent keychains in 24 hours. The first test cut on the diode profile cracked straight down the middle (surprise, surprise — clear sheets don't absorb blue wavelengths the way dark acrylic does). We re-profiled on scrap, found a combo that worked, and shipped on time. Cost us 20 minutes of testing and saved a 24-hour deadline.
Also worth doing: keep a material library with photos. Every successful settings combo gets logged with a picture of the result. It's saved us a ton of retesting.
Can the xTool F1 Ultra cut metal?
Engrave and mark metal: yes. Cut through structural metal: no. That distinction matters, and I state it before quoting any job.
The F1 Ultra's 20W fiber laser is genuinely good at annealing stainless steel for that dark, permanent mark (tumblers, knife blades, nameplates), engraving anodized aluminum, marking brass and titanium with fine detail, and removing coatings to expose contrast.
But cutting through a 2mm steel plate? That's high-wattage fiber, CO2 with oxygen assist, waterjet, or plasma territory. The F1 Ultra doesn't replace those machines, and I'm not going to pretend it does — I've tested the boundary (not that the workpiece survived). When a client needs metal through-cuts, we route that part to a cutting partner and handle the engraving and finishing here.
Setting that boundary early is how we've avoided the 9 PM "wait, you said metal cutting..." phone call.
Custom laser engraving on wood: how to get it clean
Wood is where the F1 Ultra looks magical — clean contrast, fast runs, huge design freedom. But clean engraving is 80% preparation and 20% settings.
First, image resolution. The print industry standard is 300 DPI at final output size, and laser engraving follows the same rule. A 3000×2000 pixel image engraved at 10 inches wide is exactly 300 DPI — crisp. Stretch that same image to 40 inches wide and it drops to 75 DPI, which looks terrible. Most "bad engraving" complaints are a resolution problem, not a laser problem.
Second, the wood itself. Birch plywood and alder are forgiving and high contrast. Maple gives beautiful detail but engraves light, so we boost power a little. Walnut and dark hardwoods are low contrast, so we often paint-fill the engraving for readability. Pine has resin pockets that char unevenly. For corporate projects, color matching matters too — we keep a Pantone Color Bridge at the shop to match brand colors for paint-filled wood.
Our default diode settings for solid wood: light engraving at 150–200 mm/s and 60–70% power; deeper burns at 80–120 mm/s and 80–90% power. Air assist on, always — it cuts charring down dramatically.
Before any rush job, we engrave a test dot on the inside of a scrap piece. Five minutes of verification beats five days of correction. We learned that the hard way in 2023, when a walnut order burned patchy two days before an event.
Materials you shouldn't put in a laser
People assume a dual-laser machine handles anything. The F1 Ultra is versatile, but laser processing is materials chemistry, not magic.
- PVC / vinyl: releases chlorine gas — toxic to you, corrosive to the machine
- Polycarbonate: absorbs laser energy poorly and degrades instead of cutting
- ABS and HDPE: warp, melt, and smell terrible
- Galvanized or coated metal: dangerous fumes, and the coating can ignite
- Unlabeled plastics: if you don't know what it is, don't run it
From the outside, it looks like the laser just burns designs into whatever you place. The reality is that wavelength, material, and settings all have to align. The F1 Ultra's dual-laser design solves the "metal and organics in one machine" problem, but it doesn't change chemistry.
Every deadline we've blown traces back to a skipped material check. A 30-second bend or flame test on a scrap piece would have flagged the issue before we committed a whole batch. Prevention is cheaper than rework — that's the philosophy this shop runs on.
Is a laser cutter service worth it?
People ask whether they should buy an F1 Ultra and start taking jobs. My honest take after running a service studio:
A laser cutter service is worth it when you have repeat demand for what the machine does well: small-batch signage, engraved products, event materials, personalization prototypes. The F1 Ultra is a strong fit because the dual laser lets you say yes to wooden signs and stainless steel tumblers with one machine.
It's not worth it if the plan is "buy the machine, then find customers." The machine doesn't make the business — repeat demand and material knowledge do. Our first customers came from local event vendors and a corporate gift broker; both needed fast, small-batch turnaround, which is exactly the F1 Ultra's sweet spot.
One caution: per the FTC's advertising guidelines (ftc.gov, as of January 2025 at least), claims need to be truthful and substantiated. Don't advertise "same-day metal cutting" if you can't cut metal, and don't promise "any material" before you've tested it. That's not legal hedging — it's survival math for a small shop. One publicized failure costs way more than an honest scope conversation.
The 7-point rush checklist I use before every order
The most common question is "how do you turn things around so fast?" The real answer: we're slow where it counts, before the laser turns on. Every rush job runs through this checklist:
- Verify material type (cast vs. extruded, wood species, coated or not)
- Test engrave or cut on scrap
- Air assist connected and clear
- Focus checked for actual material thickness
- Settings matched against the material library
- Watch the first 30 seconds of the run
- Spare material ready in case a piece needs re-running
In March 2024, a client needed 30 engraved walnut plaques in 36 hours. Normal turnaround is five business days. The alternative was that client walking into an event with printed signs. Because we'd verified the walnut lot when it arrived and dialed in the profile, the whole batch ran clean and shipped on time.
The 7-point checklist we built after that 2023 walnut incident has saved us an estimated $8,000 in potential rework since. One honest caveat: my experience is based on mid-range, small-batch jobs — event work, product prototypes, corporate gifts. If you're doing high-volume production acrylic for retail chains, your workflow will need to be more industrialized than ours. But the principle holds: check first, cut second, and respect the material's limits. That's how you turn a deadline story into a "we shipped it" story.
