xTool S1 alternatives offer three buying philosophies rather than one upgrade path. One ready box, a bare laser you kit out, or a step up in power class. Open frame diodes from Ortur, Atomstack, and Creality circle the same buyers as CO2 machines from OMTech and Glowforge, so pick a philosophy.

How much extra does the S1 class really cost?
The S1 class is not priced like other diode lasers, because it is not sold like one. The brand ships a ready box: laser, enclosure, lid interlock and air assist arriving as one unit. Open frame diodes sell the opposite way, bare rails with the module exposed, and every safety extra lands on your cart as its own line item.
So the money question that matters is total cost, not machine cost. The ready box sits at a premium price point. The kit route, a mid range open frame diode plus an enclosure and a small air assist, settles a solid step below. That leftover is the whole argument of this page.
Count the stack, not the sticker
Read the chart as a shape, not a quote. The bare diode runs about half of the all in number, the safety pieces add close to a third, and the finished kit route lands near three quarters. Per manufacturer guidance those splits shift with sales and bundles, but the shape holds: packaging is a real line item, and pretending otherwise is how budgets die.
Think of it this way
Buying the S1 class is like renting a fully furnished apartment. Buying an open frame diode is like taking an empty room and picking your own couch, lamp and smoke alarm. The furniture is the enclosure, the assist and the fume path. You can furnish it for less, only if you enjoy the shopping.
Which rival class actually threatens the S1?
The S1 class has exactly one job, bringing the diode laser indoors with the safety story already handled. The alternatives attack from three directions: some match its cutting, one crowd undercuts its price, and one class simply outruns it. Know which direction is pulling you before you compare stickers.
The open frame diode family
xTool D1 Pro, Ortur Laser Master 3, Atomstack X40 Pro, Creality Falcon 2 Pro and Sculpfun run the same diode physics with no box around them. You get the machine at a budget price point and you own the enclosure, the assist and the fume plan. On thin sheet stock the cut ceiling is the same conversation as the S1 class.
The enclosed convenience lane
The closest rival to a box is another box. The Glowforge Aura class and its enclosed cousins sell the same promise, an easy first machine with the beam behind a lid. That fight comes down to software, rotary fit and ecosystem, not raw capability. You are basically picking your favorite walled garden.
The CO2 step up
The last group is not a rival so much as a different league. Omtech, the Glowforge Pro class and the xTool P2 family run another physics entirely: premium money, real venting, a bigger footprint, and a depth and speed the diode family cannot touch. CO2 is what you graduate to, not what you switch to.
The chart draws the battle line. Diode physics, S1 class or open frame, engraves blanks and thin sheets all day, and the CO2 step up only earns its premium once depth joins the conversation. That fork is where most alternative shoppers actually stand.
The way I see it
Comparing the S1 class with an open frame diode is like comparing a meal kit with a grocery list. One arrives in a box with the steps numbered; the other hands you ingredients and trusts your Tuesday. Both feed you, only one respects your time. Pick the box that matches your actual Tuesday.
What does the enclosure premium really buy you?
The enclosure premium buys two concrete jobs, and it pays to name them. It keeps the beam behind an interlocked lid, so the laser stops the moment the lid opens, and it keeps smoke and debris in one spot instead of across the room. Neither job makes the fumes disappear.
What the enclosure does
The S1 class ships with its own box and the lid interlock built in. Open frame buyers add a laser enclosure from the accessory aisle and fit the interlock themselves, or run without one. Skipping that step is how the kit route earns its bad reputation.
What air assist does
Assist air keeps the smoke plume off the lens and blows char away from the cut line. Cleaner air over the cut means cleaner edges and a lens that stays clear longer. The S1 class puts assist in the box; open frame buyers bolt on a small pump, and the job is identical either way. The machine works, but only when the air moves.
The fume path that never goes away
Every route, ready box included, still has to move smoke somewhere: a hose to a window, an inline blower, or a filter box. The physics does not care that the laser arrived in a pretty box. Budget the fume path before you celebrate the unboxing.
So the premium buys assembly, not physics. If you enjoy the build, the S1 class premium pays for a job you would rather do yourself. If you do not enjoy the build, the premium buys the difference between using the laser and maintaining a project.
Think of it this way
An open frame laser is a great knife, honest about what it is. An enclosed diode is the same knife with a guard, because it removes one whole class of mistakes from the table. The guard is not magic; it just means you do not have to be perfect every single time. Buy the guard when you know you will not be.
How much laser do you actually need?
Right sizing starts with an honest read of your week. Engraving heavy weeks, tumblers, coasters, cutting boards and leather patches, are diode home turf, and the S1 class and every open frame rival handle the same blanks. Cutting heavy weeks, real signs and sheet goods at volume, are where diode patience runs out and CO2 starts earning its money. Be honest about which week you actually live.
Read the fit scores as priorities, not power specs. The ready box route wins the first night and the handled safety. The kit route wins the leftover budget, which is exactly how you pay for a rotary and a first stack of blanks. Both top out at the same thin sheet ceiling, so the tiebreaker is always your habits.
The smart upgrade path treats the first machine as a step, not a marriage. Start with a diode route, keep it running as the engraver, and add CO2 the season your cutting work justifies it. Machines are stairs, not spouses; the mistake is buying the top stair first.
The way I see it
The diode class is a reliable sedan and CO2 is a pickup truck. The sedan does the commute, the errands and most of the moving; the truck only earns its keep on days you haul something genuinely heavy. Most buyers buy the truck a year before they need it. Let the work call for the truck.
Is the S1 class worth it, or is the kit route the real deal?
Straight answer: the S1 class is worth its premium exactly when you value the package. The beam inside cuts the same thin sheet stock as cheaper open frame machines, so the value lives in the enclosure, the interlock and the zero assembly nights, not in the wattage story. Pay for the package only if the package is what you wanted.
The kit route wins when you treat the build as part of the hobby. One weekend of enclosure assembly and assist wiring returns the same jobs with leftover money for a rotary and blanks. The catch is that the build has to actually happen. Half of the kit route regret is people who skipped the enclosure.
Buy It If
- Buy the S1 class if you want one order, one setup, and a laser that feels finished on night one, and the premium does not make you wince.
- Buy the kit route if you enjoy the build, you will finish the enclosure, and the leftover budget wants a rotary and blanks.
- Buy the CO2 step up if your cutting list already outgrows diode speed and you have space for a bigger footprint with real venting.
Skip It If
- Skip the S1 class if the premium stings, because the beam inside is still a diode cutting thin sheets.
- Skip the kit route if you know the enclosure will sit in its box, because an unbuilt safety kit is a laser you will not run.
- Skip the CO2 step up if engraving blanks is your whole world, because you would fund cutting depth you will never use.
Think of it this way
The whole decision is a test of honesty about your own habits. The machine is never the bottleneck. The bottleneck is whether you finish the build, run the fume path and keep the lens clean. Buy the machine that matches the person you actually are on a Sunday night.
S1 class versus the field: which alternative wins your money?
Strip the marketing and the board looks like this. Four ways to spend laser money, facts in the columns, attitude in the last one. No option wins every column, so read the rows against your own habits. That is the entire homework.
| Option | Safety story | Job ceiling | Best For | Verdict |
|---|---|---|---|---|
| The S1 class, xTool S1 as the example | Ready box: enclosure, lid interlock and air assist included | Thin sheet cutting and engraving at diode speed, rotary ready | Buyers who want the easiest, safest first setup | Convenience is real, and the price tag knows it |
| The open frame diode family, xTool D1 Pro, Ortur, Atomstack, Creality | Safety gear sold separately: enclosure, assist and fume path are your build | Same diode ceiling with more machine per unit of money | Kit builders and budget first buyers | Best value on the board, if you finish the build |
| Enclosed diode rivals, the Glowforge Aura class | Ready box with guided cloud software | Similar diode ceiling in a friendlier package | Absolute beginners who want the simplest start | The easiest start, with the most lock in |
| The CO2 step up, Omtech, the Glowforge Pro class, xTool P2 | Enclosed cabinet with real venting and a bigger footprint | Deeper cuts, faster passes, cleaner acrylic edges | Cutting heavy shops and growing businesses | The genuine upgrade, once depth is the bottleneck |
Notice the shape: each rival beats the ready box on exactly one axis, value, ease or depth, and none beats it on everything. The S1 class stays unbeaten only on the whole package at once; the rivals win the moment you name your one priority.
So, which S1 alternative wins in 2026?
The Bottom Line
Bottom line: for the reader who wanted the S1 class for its all in story, the ready box still wins when convenience is the whole point, and that is a real reason, not a weak one. For the reader with one weekend of patience, the open frame diode with an enclosure kit is the value winner, same thin sheet cuts at meaningfully less money. And CO2 is not an S1 alternative at all; it is the promotion you earn the day depth becomes the bottleneck.
