The best laser engraver for a small business is not the one with the biggest number in its name — it is the one whose light matches what you already sell. Wood, leather, dark acrylic and slate belong to an enclosed diode, and the xTool S1 in its 40W version is where most first paid workflows should start. Clear acrylic, glass and thick board need CO2, which on a desktop means the xTool P2S. Bare metal is a third category entirely: it takes a 1064 nm fiber source, and the xTool F1 Ultra is the machine that also cuts wood.
That is the order this guide follows, because the wattage on the box tells you less about fit than the wavelength does. Three things decide whether a laser can run as a business rather than a hobby: what it cuts, whether the space you have can safely host it, and what happens to your throughput the day the tube, the software or the cloud stops cooperating.
What each light source can and cannot do
Diode, 445–455 nm. The light is absorbed by wood, leather, dark acrylic, slate and card, and reflected by bright bare metal — which is why a plain diode cannot mark stainless without an infrared module. It passes through clear and light-coloured acrylic instead of cutting it. Where diode machines lose to CO2 is not the headline thickness but the hours: thick stock means many slow passes, and time per job is what a small business sells.
CO2, 10,600 nm. Cuts clear and coloured acrylic, plywood, MDF, leather and thick hardwood, engraves glass, and does not mark bare metal or uncoated steel without a spray or coating. On a desktop it means a water-cooled glass tube, which brings coolant, a bigger footprint and a tube you will eventually replace.
Fiber, 1064 nm. The only one of the three that marks stainless, brass, aluminium and titanium directly. It is a marking tool: 20W deep-engraves and embosses, and cutting is limited to thin sheet — xTool publishes 0.4 mm brass, 0.3 mm stainless and 0.2 mm aluminium on the F1 Ultra with repeated passes. A 2W infrared module of the kind bundled with some diode machines marks under 0.1 mm per pass and does no colour marking.
The wattage itself is not a standardised unit. Creality publishes an optical column on the Falcon2 Pro spec table (22W, or 40W + 1.6W on the larger head) and Sculpfun states that its S30 Ultra 22W and 33W names are built from a single 6W diode in a combined design, not one 33W emitter. xTool lists the S1 as 40W without publishing an optical figure for the module. None of that makes one machine better; it makes the number a poor way to compare brands. xTool's published single-pass cuts for the S1 40W — 18 mm cherry, 15 mm dark opaque acrylic, 0.1 mm stainless — are the more useful reference, and they are still the manufacturer's figures rather than a measurement.
Class 1 on the brochure, Class 4 in the room
Laser class decides where a machine can live, and it is the specification buyers check last. A Class 1 product is safe in normal use with the enclosure intact; a Class 4 source is not eye-safe in the open. What matters is how conditional Class 1 gets within one model line:
- The xTool S1 is Class 1 only with the baseplate installed, or with the riser base and its doors closed. With the riser plus the conveyor feeder it is no longer a Class 1 setup, and goggles are not in the box.
- The xTool P2S is stated Class 4 on its product page; its FAQ explains that units ship with a Class 1 or a Class 4 sticker depending on configuration, Class 1 requiring the work area fully enclosed. A riser base can let diffused beam out.
- The xTool P3 ships Class 1 with a Class 4 laser inside, and becomes Class 4 once the conveyor feeder is fitted. The F1 Ultra, F2 Ultra and F2 Ultra UV are stated Class 4 on their pages.
- Creality lists the Falcon2 Pro enclosure as FDA Class 1. The Glowforge Pro is Class 4; the Plus is the Class 1 unit in that range.
- Open-frame diode machines — Sculpfun's S9 and S30 family, and most budget kits — have no enclosure and no interlock at all, whatever the hinged eye shield suggests.
Class 1 does not mean you can leave a job running either: wood and acrylic can ignite, and flame detection is a backstop, not a substitute for watching. Never leave a running machine unattended and keep a CO2 extinguisher within reach. It does not mean you can skip ventilation either. An enclosure keeps the beam in, not the smoke: every machine here needs its exhaust routed outdoors or through a purifier. Eyewear has to match the wavelength, 445–455 nm for a diode and 1064 nm for fiber, and both on a dual-head machine — xTool lists OD6+ for the F1 Ultra and quotes a nominal ocular hazard distance of about 4 metres. Gweike sells its goggles as a separate item.
No laser on this list should touch PVC, vinyl or any chlorinated material. The vapour is corrosive and damages optics and mechanics, and it is a health problem in a room you work in. Polycarbonate and ABS also release fumes you do not want indoors.
The costs that land after the machine
Venting. A hose is not a system. The P3 has no built-in exhaust fan at all — an inline fan ships in the box and the purifier is an extra. The P2S exhausts through an internal fan to open air or to an xTool purifier. Budget the window plate, the hose run and, in a shared building, the purifier.
Cooling. Every CO2 tube needs a coolant loop; the P2S and P3 use distilled water with antifreeze in a cold room. OMTech's standard 60W package includes a pump and tank but no chiller — that is a separate line. Glowforge hides the cooling inside the case, which is a large part of its appeal.
Power. The P3 draws up to 1,400 W and wants a 110 V circuit to itself; the Glowforge Pro peaks around 800 W. Check the circuit, not just the socket count.
The tube is a consumable. OMTech quotes tube life as 1,000 hours in one document, 2,000 in its spec table and 6,000 on a replacement-tube page — treat any figure as an estimate with an unknown date. xTool quotes about 10,000 hours for the P3 tube. Diode modules degrade too, but per module and more slowly.
Software. This is where a production machine can fail you without breaking. The Glowforge Pro runs browser-only software and needs a live connection. The xTool P3 runs xTool Studio, and xTool's support pages say not LightBurn or XCS. The P2S runs LightBurn but loses the camera, autofocus and framing. The S1 runs LightBurn for basic operations only, without module position or curved mode. The Falcon2 Pro runs full LightBurn.
Floor space and weight. The P2S is 1000 × 639 × 268 mm and 45 kg; the OMTech AF2028-60 is 249 lb. Both need a bench built for them and two people on delivery day.
The machines, by what you sell
The enclosed diode most shops should start with: xTool S1 40W
The 40W S1 gives you 498 × 319 mm of bed, 600 mm/s of travel, a 455 nm module and a 20 kg body, with a lid-open stop, an e-stop, a key lock and flame detection around the work area. xTool's published single-pass cuts are 18 mm cherry, 15 mm dark opaque acrylic and 0.1 mm stainless — the last one is marking, not cutting. The 20W version cuts roughly half those depths per xTool.
Two things to plan for. The class condition above: baseplate in, or riser doors closed, and goggles bought separately. And the lens — at 40W, xTool puts protective-lens cleaning at roughly every 30 minutes of use, which becomes the real rhythm of a production day. The RA2 Pro rotary covers tumblers, and the 2W 1064 nm IR module adds shallow marking on bare metal, but it is a marking module, not a metal cutter. This is the machine for wood signs, leather patches, slate coasters, dark acrylic and tumblers. It is not the machine for clear acrylic or bare stainless: no amount of wattage fixes a wavelength.

The same job with a published optical figure: Creality Falcon2 Pro 22W
400 × 415 mm of bed, 664 × 570 × 328 mm of footprint, 18–19.5 kg, fully enclosed with dual sensors, camera positioning, full LightBurn support and the Rotary Kit Pro as an accessory. Creality states 22W optical on the spec table, and the Amazon bundle pairs that diode with a 2W infrared module for shallow marks on coated and bare metal — which makes cut charts easier to compare against other brands than a bare product name does.
Owners report the exhaust-port assembly arriving loose and the module fan shrouds needing gasket tape to seal. Check both before the first paid job, because an exhaust leak in an enclosed machine puts the smoke back in the room. For the same material list as the S1, with a slightly larger bed and a thinner accessory ecosystem, it is the cheaper route into an enclosed diode.

When clear acrylic and thick board pay the bills: xTool P2S 55W
CO2 at 10,600 nm, 600 × 305 mm of bed, one-pass cuts of 18 mm basswood and 20 mm acrylic per xTool, clear acrylic up to 20 mm, plywood advised no thicker than 12 mm, about 75 dB in operation. At 45 kg and 1000 × 639 × 268 mm, measure the bench and the doorway before ordering.
It is a water-cooled tube machine: coolant to mix, an exhaust route outdoors or to a purifier, and xTool's own guidance is not to cut continuously for more than four hours even though the machine is rated for far longer stretches. LightBurn runs it without camera, autofocus or framing. The rotary handles cylinders from 3 to 42 mm with the baseplate in place. On class, read the sticker on the unit you receive — xTool's page says Class 4, its FAQ says Class 1 or Class 4 by configuration — and plan the room for the worse of the two.
If you mark metal for a living: xTool F1 Ultra
20W fiber plus 20W diode in a galvo head, 10,000 mm/s, a 0.03 × 0.03 mm fiber spot against 0.08 × 0.10 mm on the diode side, 220 × 220 mm of area (220 × 500 mm with the conveyor) and 145 mm of processable height. The fiber marks and deep-engraves stainless, brass, aluminium and titanium; the diode side cuts 12 mm basswood and 12 mm black acrylic. Fiber cutting is thin sheet only — 0.4 mm brass, 0.3 mm stainless, 0.2 mm aluminium with repeated passes.
Two operational facts decide whether it suits your bench. It is stated Class 4, with OD6+ eyewear and a hazard distance around 4 metres, so it does not go in an open shop corner. And the autofocus tolerates about 0.5 mm of thickness deviation, so warped tags need to sit flat or the mark drifts. Embossing brass and copper needs a depth map rather than more power. That bed size means jewellery, tags, hand tools and phone-sized plates — not sheet work.

Fiber without paying for a diode you won't use: Gweike G2 Pro 30W
A 1064 nm ytterbium fiber source, 150 × 150 mm of bed, 30W in the name, an enclosed shell and full LightBurn support, with CE and FDA listed on the page. It is the cheaper way into a fiber source when metal is the entire business and the F1 Ultra's diode side would sit idle. Gweike does not state a laser class on the page, so treat the machine as a Class 4 source: goggles are a separate purchase, extraction is on you, and an enclosure is not a certification. For rings, tags, tool marking and small batches the bed is enough; for anything larger it is not.

The open-head fiber alternative: ComMarker B4 20W
Two lenses, 110 mm and 200 mm, 1064 nm, EZCAD2 bundled and LightBurn on a separate licence, Windows only, manual focus calibrated per lens. The galvo head is open — no enclosure at all — so goggles and extraction are not optional, and the class is not settled between the manual and the vendor's own material; treat it as Class 4. Focus calibration per lens is the step new owners underestimate, and it is the difference between a crisp mark and a faint one. A one-person metal-marking shop can run this profitably; a shop that also sells wood cannot, because there is no diode here.

The production tier, with a software condition: xTool P3
80W CO2 over 915 × 458 mm, Class 1 overall with a Class 4 laser inside, Class 4 once the conveyor feeder is fitted, 400 mm/s vector, one-pass 20 mm wood and 25 mm clear acrylic, about 10,000 hours of tube life per xTool, and up to 1,400 W of draw that wants its own circuit. Accessories from the P2 and P2S do not fit it.
The condition is software: xTool's support pages say the P3 runs xTool Studio only, with no LightBurn or XCS (the product page lists LightBurn, so confirm before you rely on it). If your templates, your trained operator or your whole workflow live in LightBurn, this machine means changing tools rather than just buying one. It also has no internal exhaust fan — the inline fan is in the box and the purifier is a separate purchase. xTool sells it direct.
Big bed, real floor space, and a warranty trap: OMTech 60W
The AF2028-60 gives 20 × 28 in of bed, a 60W water-cooled tube, 249 lb of cabinet, pass-through slots front-to-back and side, RDWorks in the box and LightBurn only in packages that name it. The standard package includes a pump and tank but no chiller. Mirror alignment, coolant management and tube swaps are ownership tasks, not service calls.
Two things to know before paying. Tube life is quoted as 1,000 hours in one document, 2,000 in the spec table and 6,000 on a replacement-tube page, so treat the tube as a consumable with an unknown date. And OMTech's warranty — two years on parts, six months on 40–60W tubes — does not apply to machines bought from third-party marketplaces such as Amazon or eBay. Buying direct is what buys you the support. The cabinet should be treated as a Class 4 source regardless of what the listing says.
The plug-in CO2 with a cloud in the middle: Glowforge Pro
45W CO2, 279 × 495 mm, Class 4 (the Plus is the Class 1 unit), 800 W peak, autofocus, a pass-through slot for 1/4 in material, and cooling handled inside the case — no chiller to fill, no coolant to mix, which is the entire argument for it. It still needs the Compact Filter or an openable window within about 8 feet.
The trade is the cloud: browser-based software, 2.4 GHz Wi-Fi, no local mode, and a machine that stops when the connection does. Owners report that letting a subscription lapse costs access to cloud-stored projects. For a shop where the laser is the bottleneck six days a week, that is a business risk rather than an inconvenience. Confirm whether the unit you are offered is new or rebuilt before committing.
How to choose, in one pass
| What you sell | Light source | Machines that fit |
|---|---|---|
| Wood signs, leather patches, slate, dark acrylic, tumblers | 445–455 nm diode | xTool S1 40W · Creality Falcon2 Pro 22W |
| Clear or coloured acrylic, glass, thick hardwood, sheet work | 10,600 nm CO2 | xTool P2S · xTool P3 |
| Stainless, brass, aluminium tags, jewellery, hand tools | 1064 nm fiber | xTool F1 Ultra · Gweike G2 Pro 30W |
| Metal plus wood on one small bench | fiber + diode | xTool F1 Ultra |
Five checks before you pay. Add the accessories to the budget — rotary, air assist, chiller, purifier, goggles — because none of them is optional in daily use. Confirm the laser class on the certificate or sticker for the exact version you are buying, since versions differ inside one model line. Measure the exhaust path, including hose length and where the purifier sits. Check the circuit against the machine's draw. And read the warranty terms for the specific seller, since at least one brand here voids coverage on marketplace purchases.
For a first paid workflow, an enclosed diode remains the lowest-risk entry: a 40W S1 or a 22W Falcon2 Pro cuts wood, leather, dark acrylic and slate, runs on a normal circuit and vents through a window. Move to CO2 the week clear acrylic, glass or volume cutting becomes the request, and to fiber the week customers ask you to mark metal. Buying the wrong wavelength first is the expensive mistake; everything else on this list is an accessory.
