xTool M1 vs Glowforge Spark: Enclosed Laser Engraver Showdown
Two enclosed laser engravers for crafters who want plug-and-play simplicity — but they're built on totally different philosophies. Here's what I found after testing both.
xTool M1 vs Glowforge Spark: Enclosed Laser Engraver Showdown
If you’ve been following the laser engraver market for even a few months, you’ve watched something interesting happen: Glowforge, the company that essentially invented the “appliance-style laser cutter” category, now has serious competition from xTool in the enclosed machine space. The Glowforge Spark is Glowforge’s more accessible entry point, while the xTool M1 approaches the same audience from the diode laser side, with a bonus blade cutter attached.
These two machines appeal to the same person: a crafter or small business owner who wants an enclosed laser engraver with a good camera system, minimal setup, and software that doesn’t require learning GRBL commands. They’re different enough in underlying technology, however, that picking the wrong one could leave you frustrated with a machine that can’t do what you specifically need.
I’ve been using the xTool M1 in my shop for about 18 months now. I got extended hands-on time with the Glowforge Spark through a friend who runs an Etsy shop selling engraved gifts. Here’s everything I’ve learned.

Quick Verdict
Buy the xTool M1 if: You want a hybrid machine that does both laser engraving/cutting AND blade cutting (vinyl, HTV), you want local software control without cloud dependency, and you need to work with a wider variety of diode-laser-compatible materials.
Buy the Glowforge Spark if: You want the simplest possible path to cutting and engraving — especially clear acrylic and light-colored materials — and you’re willing to accept cloud-based software and a proprietary ecosystem in exchange for that ease of use.

The most important spec difference isn’t size or speed — it’s the laser type. The xTool M1 uses a 10W diode laser. The Glowforge Spark uses a 6W CO2 laser. CO2 and diode lasers behave completely differently on many materials. That difference shapes every other comparison in this article.
xTool M1 In-Depth
Setup and First Impressions
The M1 arrives mostly assembled in a well-packaged box. Setup is genuinely about 15-20 minutes: remove packing materials, plug in the power and USB, connect to Wi-Fi or run via USB, and you’re ready to run your first job. The enclosure is a solid, well-built unit with a transparent lid — you can watch the laser work without eye protection risk because the lid filters the 445nm wavelength.
The machine has two tool heads: a 10W laser module and a blade cutter. You swap between them manually — it takes about 30 seconds to swap a head. The blade cutter uses a pressure-sensitive mechanism similar to Cricut machines, and once you dial in the blade depth for your specific vinyl or HTV brand, it cuts cleanly.
The built-in camera (16MP) is one of the best camera positioning systems I’ve tested on a diode machine. You place your material, the software shows you an accurate overhead view, and you drag your design onto it with about ±2mm accuracy in my experience. That’s good enough for most projects without needing to measure and manually enter coordinates.
Cut Performance on Real Materials
3mm birch plywood: Two passes at 4mm/s. This is the key limitation of a 10W diode versus a more powerful module. The cuts are clean with minimal charring, but you’re waiting for that second pass. For production work on plywood, I use this machine for engraving and switch to my D1 Pro 20W for cutting. If you’re only buying one machine and you cut a lot of 3mm plywood, the M1’s power level will be a limiting factor.
Dark acrylic (3mm): Two passes at 4.5mm/s. Cut quality is good — clean edges without excessive melt marks on the kerf. Clear acrylic does not work with diode lasers; you need CO2 for that.
Vegetable-tanned leather (2mm): Clean single-pass cut at 5mm/s. Engraving on leather looks excellent — the diode’s 445nm wavelength gives beautifully dark, crisp marks on natural veg-tan.
Anodized aluminum: Excellent engravings. This is where diode lasers genuinely outperform CO2 at this power level — the 445nm wavelength is well-absorbed by anodized aluminum, giving high-contrast marks. Dog tags, keychains, and luggage tags come out sharp.
Blade cutting (vinyl, HTV): This is the feature that separates the M1 from every other laser on this list. Vinyl decals for tumblers, HTV transfers for apparel, rhinestone transfer templates — the blade cutter handles all of it cleanly. I sell vinyl tumbler wraps on Etsy alongside engraved wood products, and having one machine handle both workflows is genuinely convenient.
Software: xTool Creative Space
xTool Creative Space handles both laser and blade workflows within the same interface, which is a more impressive software feat than it sounds. You can set up a job that does a laser engrave followed by a blade cut of a different layer — useful for things like laser-engraving a design into leather and then blade-cutting the shape.
The software runs locally on your machine (with optional cloud sync for files). This means you can use the M1 without an internet connection, which matters when your Wi-Fi goes down in the middle of a production run.
Material presets for the laser side work reliably. The blade side requires a bit of calibration for each new material/blade combination, but once dialed in, blade jobs are consistent. The full xTool accessory ecosystem — rotary attachments, conveyor feeder, fume extractor — integrates directly into the software.
Enclosure and Safety
The M1’s enclosure is one of its strongest points relative to open-frame diode machines. The lid is laser-safe for the diode wavelength — you can look at the lid while it’s running without eye protection. The enclosure significantly contains smoke and fumes, though you still need to vent it outside or use an air purifier for extended sessions. The M1’s exhaust port is compatible with 4-inch dryer hose, and I vent mine out a window during all cutting sessions.
Glowforge Spark In-Depth
Setup and First Impressions
The Glowforge Spark setup is the benchmark for laser engraver onboarding. Unbox it, plug it into power, connect to Wi-Fi, and the lid camera guides you through the process in the browser. You’re cutting within 15-20 minutes of opening the box. There’s no assembly, no firmware to flash, no COM port to identify.
The machine itself is a handsome piece of hardware — clean lines, a large transparent lid, and a slot for their Proofgrade materials on one side. The interior is spacious: 495 x 280mm usable cutting area (wider than the M1, though similar in square millimeters). The exhaust fan is built in and loud — comparable to a bathroom vent fan — so you’ll run the exhaust hose out a window during all sessions.
Cut Performance on Real Materials
Here’s where the CO2 laser makes its presence known. The Glowforge Spark’s 6W CO2 output is not a high-power machine, but CO2 lasers interact with organic materials fundamentally differently than diode lasers. The 10,600nm CO2 wavelength is absorbed by wood and acrylic regardless of color or composition. The 445nm diode wavelength has significant limitations with clear and light-colored materials.
3mm birch plywood: Single-pass cut at comparable speeds to the xTool M1. The cut quality is good — clean edges with minimal charring. For equivalent plywood work, the CO2 advantage isn’t dramatic here.
Clear 3mm acrylic: This is the moment a CO2 laser justifies its existence. The Spark cuts clear acrylic cleanly in a single pass. This is something the xTool M1 cannot do at all — clear acrylic passes diode laser energy almost entirely without absorbing it. If earrings, keychains, and clear display pieces are part of your product line, this difference is enormous.
Light-colored wood and engraving on natural wood: CO2 wavelengths produce consistent engravings on pale, light-grained wood where diode lasers struggle to produce enough contrast. Maple, alder, and light pine take clean, dark engravings from the Spark. The same wood on a diode laser produces faint or inconsistent marks.
Glass (direct engraving): The Spark can engrave glass directly — creating frosted patterns on drinking glasses, picture frames, and mirrors. Diode lasers cannot engrave bare glass at all (the glass is transparent to the 445nm wavelength). This is another capability gap with significant product implications.
Leather and wood burning: Comparable results to the xTool M1. Both machines produce clean, dark engravings on brown leather and medium-density wood.
Materials it cannot do (that you might expect): Metal engraving is beyond the Spark’s power level. Anodized aluminum requires the concentrated energy of a higher-power machine; the 6W Spark produces inconsistent results. Thick material cutting is limited — at 6W optical power, it’s not the machine for cutting 5mm+ material regularly.
Software: Glowforge App
The Glowforge app is a browser-based, cloud-only experience. You open a Chrome browser, go to app.glowforge.com, upload or create your design, and send it to the machine. The lid camera shows you your material, you position your design visually, and press the glowing button on the machine.
The experience is genuinely the smoothest in the laser industry. Glowforge’s Proofgrade materials have QR codes on the sheet; scan it with the lid camera and the app automatically configures all settings. No guessing at power and speed.
The significant limitation: no internet connection means no cutting. The machine will not operate offline. If your Wi-Fi router goes down or Glowforge’s servers have an outage, your machine is a paperweight until connectivity is restored. This has happened — Glowforge has had service outages that affected users mid-production. For hobbyists, this is an inconvenience. For someone running production work, it’s a real business risk.
The software also doesn’t support LightBurn. You’re in the Glowforge ecosystem entirely. This means no switching to a different software tool when you want more control.
Enclosure and Safety
The Glowforge Spark is fully enclosed with a built-in exhaust fan. The lid uses a CO2-safe filter. One important note: CO2 laser safety glasses are different from diode laser goggles — the 10,600nm wavelength is blocked by standard clear glass and polycarbonate, so the lid provides genuine eye protection without requiring additional eyewear. You still need to keep the lid closed while the machine operates.
The exhaust requires routing outside through a 4-inch vent hose; the Glowforge compact filter (sold separately, ~$250) recirculates air through an activated carbon filter for indoor use without a window vent.
Head-to-Head
Cut Quality
Depends entirely on your materials. On clear acrylic, light wood, glass, and fabric: the Glowforge Spark wins decisively. On anodized metals, dark acrylics, and leather: the xTool M1 is comparable or better. Choose based on your primary material.
Speed
Draw for most practical purposes. Both are enclosed machines running conservative speeds due to their moderate power levels. Neither is a production workhorse — both are hobbyist/small-batch machines.
Software
Glowforge Spark for simplest experience; xTool M1 for control and offline capability. The Glowforge app is the most frictionless software in the laser industry, but the cloud dependency and proprietary lock-in are real costs. xTool Creative Space is excellent and runs locally.
Versatility
xTool M1 wins with the blade cutter. If vinyl and HTV are part of your product mix, the M1 does something the Spark cannot. The Spark wins on material versatility within the laser domain (clear acrylic, glass, fabric).
Value
xTool M1 wins on price-to-capability for most diode-compatible workflows. At $999, it includes a blade cutter, a capable 10W laser, and excellent software. The Spark at $599 is a very capable CO2 machine but the proprietary software ecosystem adds hidden long-term costs (Proofgrade materials are premium-priced, and the compact filter is $250 extra if you can’t vent outside).
Safety
Draw. Both are fully enclosed machines with built-in exhaust. Both require proper ventilation. The Glowforge’s lid provides CO2-safe eye protection passively; the xTool M1’s lid provides 445nm diode protection passively. Neither requires additional goggles during enclosed operation.
Who Should Buy Which
Buy the xTool M1 if:
- You work with vinyl, HTV, or adhesive materials and want one machine for everything
- You need to run jobs offline (no cloud dependency)
- Your materials are primarily dark acrylics, wood, leather, and anodized metal
- You want to stay in the xTool ecosystem (RA2 Pro rotary, accessories)
- You value local software control and LightBurn compatibility as a future option
Buy the Glowforge Spark if:
- Clear acrylic is a significant part of your product line (earrings, keychains, display pieces)
- You want to engrave glass directly (drinking glasses, picture frames, mirrors)
- You work with light-colored natural wood and want consistent engravings
- You want the simplest possible beginner experience with zero technical setup
- You’re comfortable with cloud-only software and the risks that entails
Neither machine if: You’re looking for maximum production speed and cutting power. Both are hobbyist-to-light-production machines. For serious volume work, step up to a 20W+ diode (xTool D1 Pro 20W) or a higher-watt CO2 machine (Glowforge Pro, OMTech).
Bottom Line
This comparison hinges almost entirely on one question: do you need to cut and engrave clear acrylic or glass?
If yes, the Glowforge Spark is worth the trade-off of cloud dependency and proprietary software. CO2 laser technology handles those materials in ways a diode laser simply cannot replicate regardless of power level.
If no — if your work is primarily wood, leather, dark acrylics, and anodized metal — the xTool M1 gives you more capability per dollar, the bonus blade cutter, offline operation, and a more open software ecosystem.
Both machines need ventilation — exhaust hose out a window, always. Both produce fumes from cutting that require adequate airflow. The enclosed design contains smoke better than open-frame machines, but it doesn’t eliminate the need to vent outside.
