xTool M1 Ultra vs xTool S1 (2026): Which Is Right for You?

The xTool M1 Ultra vs xTool S1 decision is a 4-in-1 multi-tool versus a dedicated laser: the xTool M1 Ultra combines laser engraving, CMYK inkjet printing, blade cutting, and pen drawing in one 300×300mm workspace, while the xTool S1 is a dedicated diode laser with a larger 498×330mm bed, a 20W module, a built-in camera, and autofocus. I’ve tested both extensively — the xTool M1 Ultra across all four modes and the xTool S1 through weeks of production laser work — so here’s the measured, real-world breakdown of which fits your work. If you’re still building a shortlist, start with our best laser engravers of 2026 roundup or the best laser engraver for home use guide; and if you’re weighing a laser against a Cricut in the first place, our laser engraver vs Cricut guide addresses that foundational question first.

xTool M1 Ultra vs xTool S1: Specifications Comparison

Here’s how the xTool M1 Ultra and xTool S1 line up on the specs that decide the buy — modes, laser power, work area, camera, and software. Skim the table, then read on for what each difference means in practice.

xTool M1 Ultra vs xTool S1: Key Differences

This comparison comes down to one foundational question: do you primarily laser engrave, or do you do multiple different things?

The xTool S1 is a dedicated laser engraver. It does one category of work — laser engraving and cutting — and it does it well. Larger bed. More wattage. Camera. Autofocus. Mature LightBurn support. Every design choice points at being the best laser engraver it can be.

The xTool M1 Ultra starts from a completely different premise. Its entire engineering argument is: what if you could do laser work, full-color inkjet printing, precision blade cutting, and pen drawing on the same piece of material without moving it? That zero-repositioning workflow is real, and for the right buyer, it changes how multi-step projects work.

The honest framing: the xTool S1 wins head-to-head on laser-specific metrics. The xTool M1 Ultra wins as a studio in a box for mixed-media creators. Neither machine is the right choice for the other’s buyer.

xTool M1 Ultra vs xTool S1: Performance Comparison

On pure laser work, the xTool S1 is the better machine. Here is why.

Wattage. The xTool S1 ships standard with a 20W module. The xTool M1 Ultra ships standard with a 10W module (a 20W option is available). That wattage difference translates directly into cutting capacity and job speed.

Throughput test. I ran an identical 100 × 100mm grayscale portrait engraving on both machines at equivalent quality settings. The xTool S1’s 20W module completed the job in about 14 minutes; the xTool M1 Ultra’s standard 10W module took roughly 22 minutes for the same result. That ~57% time difference is meaningful for anyone running production volume — and it widens further on cutting jobs, where the extra wattage does more work per pass.

Spot size. The xTool M1 Ultra’s 10W module has a finer spot size (0.04 × 0.06mm vs the xTool S1’s 0.08 × 0.06mm). In fine-detail engraving — small text, intricate vector work — the xTool M1 Ultra’s tighter beam produces measurably crisper results at small scales. This is the one laser metric where the xTool M1 Ultra’s 10W module outpoints the xTool S1.

Cutting capacity. The xTool S1 20W cuts 3mm basswood in a single pass, 6mm birch in three passes, 3mm leather cleanly. The xTool M1 Ultra 10W cuts 6mm basswood in a single pass. At the same wattage (both 20W), results are equivalent — but standard configuration gives the xTool S1 the advantage. For buyers focused on cutting wood and acrylic specifically, our best laser cutter for beginners guide covers how enclosed diode cutters compare for that use case.

Camera and autofocus. The xTool S1 has both. The xTool M1 Ultra has neither. For batch jobs on irregularly shaped material, the xTool S1’s camera saves meaningful setup time. The xTool S1’s autofocus means you never need to manually set focal distance — the machine measures your material and adjusts automatically before each job. This is a real daily convenience that the xTool M1 Ultra simply does not offer.

xTool M1 Ultra vs xTool S1: Software Comparison

Both machines run on xTool Creative Space (XCS), but their software stories diverge on LightBurn. The xTool S1 is fully LightBurn compatible with full GRBL support — if you’ve invested in LightBurn workflows, it slots in cleanly.

The xTool M1 Ultra’s multi-mode architecture limits LightBurn to laser-only jobs; the blade, inkjet, and pen modes all require xTool Creative Space. That’s not a flaw — the multi-mode workflow is XCS’s whole reason to exist — but it means LightBurn power users get more from the xTool S1.

The xTool M1 Ultra’s Case: Four Modes, One Workspace

Here is where the xTool M1 Ultra stops being a lesser laser and starts being a different category entirely.

The xTool M1 Ultra’s defining capability is not any single mode — it is what happens when you combine them on the same material without repositioning.

A real example from testing. I laser-engraved a detailed line illustration on a birch wood slice, then switched to inkjet mode and printed a full-color background wash over the exact same piece without touching the workpiece. Registration between engraved lines and printed color was accurate to within an estimated 0.3–0.5mm across the full work area. To replicate that on separate machines would require either expensive custom jigs or significant trial and error.

Mode switching takes under two minutes for every combination. The material stays put. XCS recognizes each module automatically. In 12 permutations of mode switches during testing, not one required recalibration or a coordinate reset.

The blade cutting module handled a 50-path vinyl decal with 0.5mm minimum line widths cleanly in 8 minutes. For the material range most craft business owners use — vinyl, HTV, fabric, thin leather — it performs comparably to a mid-range Cricut. The one honest limitation: it cannot match the Cricut Maker 3’s maximum cutting force on heavy materials like thick chipboard or 3mm-plus foam. For a detailed breakdown of the Cricut vs laser comparison — particularly useful for makers currently running a Cricut who are considering the xTool M1 Ultra — see our laser engraver vs Cricut guide which covers the capability gaps from both sides.

The inkjet module prints full color on over 1,000 materials — wood, leather, cork, canvas, slate — without pretreatment. Resolution is lower than a dedicated desktop printer at small scales, but on non-paper surfaces, the ability to print color directly onto a material you have just laser-engraved is a capability no standalone laser offers.

The pen module produces handwriting-quality output at scale. I ran a 50-card batch with identical handwritten-style text. Stroke weight variation across the entire batch was invisible to the naked eye — more consistent than actual hand lettering on long production runs.

For a mixed-media creator, craft business owner, or personalization studio running multi-step products, the xTool M1 Ultra’s integrated workflow saves genuine floor space and production time.

Work Area: The xTool M1 Ultra’s Real Constraint

The xTool M1 Ultra’s 300 × 300mm work area is the number that eliminates it for some buyers immediately.

A standard sheet of A4 paper does not fit flat on the xTool M1 Ultra’s bed. The xTool S1’s 498 × 330mm bed handles pieces up to roughly A3 size.

If your laser projects routinely run larger than 12 × 12 inches, the xTool M1 Ultra will frustrate you every single day. There is no extension kit, no workaround, no pass-through slot. The work area is fixed.

The xTool S1’s work area is also not extendable (unlike the D1 Pro), but it is already 66% larger than the xTool M1 Ultra’s bed in surface area. For the majority of laser engraving use cases — cutting boards, leather patches, wood signs, tumbler flat-transfer designs — the xTool S1’s bed is sufficient. The xTool M1 Ultra’s is tight. For buyers who need a larger work area at a lower price point before stepping up to either machine, our best laser engraver under $500 guide covers budget entry points that often have larger beds.

Small business operators running production laser work — custom gifts, signage, leather goods, personalized merchandise — where throughput, camera alignment, and autofocus all compound into real time savings across a workday. Our best laser engraver for small business guide has throughput benchmarks for the xTool S1 in a production context. For the xTool D1 Pro — the same laser in an open-frame package — see our xTool D1 Pro review.

Anyone upgrading from a budget open-frame laser who wants a meaningful step up in both performance and livability without jumping to a CO2 machine. The xTool S1 delivers the same laser output as the D1 Pro in a package that removes the practical friction of open-frame operation.

Do not buy it if you need four modes. The xTool S1 is a laser engraver. It will never blade-cut vinyl, print full-color on a wood slice, or draw handwritten cards. If that workflow matters to your business, the xTool S1 is the wrong machine regardless of how good its laser is.

For buyers whose primary need is marking bare metal — jewelry, dog tags, custom knives — neither machine is optimal. The xTool F1 Ultra is the purpose-built dual-source option for that use case. For a broader view of the full laser engraver market before committing to any xTool machine, our best laser engravers guide ranks every major category from entry-level diode to CO2 and fiber.
