Single UV, Dual UV, or UV-DT: Which version of the xTool O1 Omni is right for you?

The xTool O1 Omni now has a specifications page, a price, and three versions. And here is the part that almost nobody emphasizes enough: the ink configuration is fixed and cannot be changed after purchase. There is no upgrade, no kit, and no “we’ll see about it next year.” You choose once.

This article is intended to help you make the right choice. We’ll go through the official specifications, actual European prices, and the trade-offs of each version without dressing them up.

The three, in one sentence each

This is how xTool itself defines them:

Single UV. The entry-level option for personalizing rigid materials: wood, acrylic, glass, metal, ceramics, plastic, phone cases, signs, and tumblers.

Dual UV. For those seeking advanced UV applications and effects: in addition to rigid materials, soft UV materials such as leather and canvas, flexible white ink, fluorescent colors, and the fastest texture printing of the three.

UV-DT. The most versatile for materials: rigid and fabric. Cotton, polyester, tote bags, T-shirts, sweatshirts, and DTF film.

The specifications, field by field

This is what the official specifications page says, not what the video says:

The channel abbreviations, where everyone gets confused: W is white, V is varnish, RW is rigid white, FW is flexible white, FR is fluorescent red, and FY is fluorescent yellow.

Notice a detail in the table that is easy to overlook: the work area and maximum relief are identical on all three. What changes between versions is not how large you can print, but what you print with.

Regarding speed, a prelaunch specification sheet is circulating that attributes 9.7 sq ft/h to the Single and UV-DT, and 17.2 to the Dual. That figure does not appear on the official specifications page today, so we provide it with its source and not as a catalog figure. It does, however, align with what a beta tester who owns the UV-DT reports: their machine prints at the same speed as the single-head model. The faster one is the Dual.

Prices excluding VAT from the European store

Eight combinations, not nine: the Single UV does not have a Versatile Bundle.

The Rotary Bundle adds the rotary attachment, which costs €402.33 [xTool EU] on its own. The Versatile also adds the laminator and roll feeder, which cost €905.48 as a set [xTool EU] separately. Do the math before deciding: in some cases, the bundle upgrade costs more than buying the parts separately, and there are threads in the community asking exactly that without having received a clear answer.

The compromise xTool has shifted

Here’s the analysis that really matters, and it isn’t ours: someone in the community put it very well, and we agree.

Desktop UV printers have always involved an uncomfortable compromise: rigid white ink or flexible white ink. Rigid white is best for wood, acrylic, or metal. Flexible white is the one that can withstand bending without cracking, and it’s what you need for leather, canvas, or a tote bag. On single-head machines, you choose one and live with it.

Many people expected the Omni to solve that dilemma. But xTool has done something else: it has shifted the ink compromise to the choice of machine. Now you don’t choose which white ink to load; you choose which version to buy, and with it which white inks you’ll be able to use throughout the equipment’s lifetime.

That’s why so many people are stuck. The question is no longer “which printer should I buy?” but “what am I going to be doing three years from now?”

Three questions to get unstuck

1. Are you going to print on something that bends?

Leather, faux leather, canvas, tote bags, patches. If the answer is yes and it’s a genuine part of your business, you need flexible white, and that’s currently available only on the Dual UV. If it’s just an occasional indulgence, don’t buy an entire machine for it: UV DTF transfer covers quite a few of those cases from any of the three.

2. Are you going to print on actual garments?

“Seriously” means T-shirts and sweatshirts with some regularity, not one for your brother-in-law. If so, the UV-DT is the only one that does it directly. Before deciding, read what the full DTG workflow involves, because it’s not just a matter of inserting the T-shirt and pressing print.

3. How many printheads do you want to maintain?

This is the question people ask least and the one that has the biggest impact on the budget. The dual-printhead versions come with two expensive consumable components instead of one. And the second printhead has to be maintained with ink and humectant even if you barely use it, because it is part of the circuit. If you are going to make little use of what the second printhead offers, you are paying for it twice: when you buy it and when you maintain it. The full calculations are in the cost article.

Our choice

We bought the Dual UV in the Versatile Bundle [xTool EU], paid for in full. The short version: we work with quite a bit of material that bends—faux leather, canvas, bags—and the flexible white opens up products we currently turn down; and the rotary and laminator were not optional for us, because the thermal tumbler and finished sticker make up half our catalog.

We're not saying it's the right choice for you. In fact, if you only work with wood, acrylic, and metal, the Single UV gives you more machine for your money: the same working area, the same relief, the same vision system, and a single printhead to replace.

And one final disclaimer that we apply to ourselves: the machine is not in our workshop yet. Everything above comes from the official specifications, published prices, and what beta testers report. Once we have it in front of us, if any of this doesn't hold up, we'll say so here.

Update: July 28, 2026

A new factor that could affect this decision, especially if you're choosing between Single and Dual: xTool is working on bringing flexible white to the single printhead, the one used in all three versions. The CEO mentioned it during the launch livestream, and brand staff have confirmed in the official group that it is in development. No date or commitment.

If it arrives, the change would be made by purging the white ink line—around 30 ml of ink, so you would have to choose one white and stick with it rather than switching daily—and on the UV-DT, the flexible white cartridge would most likely take the place of the textile white cartridge, since both are double-width. Full details here.

What to do with this information: nothing, if you need the machine now. Buying based on an announced feature without a date is the mistake that already cost us half a year. But if your only reason for paying an extra thousand euros for the Dual was the flexible white ink, and you are not in a hurry, this is a good time to wait and see how it turns out.

And remember the actual schedule: shipments begin in stages in August; they do not arrive in August. The August 15 date you will see circulating is the end of the preorder price, not a delivery date.

Update of August 12, 2026: confirmed materials and workflows

xTool has published an official matrix clarifying what each version can do. The main conclusion remains unchanged, but it does correct two common misconceptions:

• All three versions support UV DTF, as well as direct UV printing, relief, lenticular printing, and foil. The “DT” in UV+DT refers to the textile printhead, not the UV DTF transfer.
• Direct leather printing is reserved for the Dual UV in the matrix because of its flexible white ink. Printing on fabric via DTG/DTF belongs to the UV+DT.

The table also confirms acrylic, metal, glass, ceramics, compatible plastics, wood, paper, and lenticular film across all three; it recommends primer for smooth, hard surfaces such as glass, ceramics, metal, and acrylic; and it distinguishes UV DTF A/B films from textile DTF film. We have prepared a complete guide to materials, films, and primers so this comparison does not turn into a list of consumables.

The decision rule is now sharper: rigid materials and a single printhead, Single; rigid materials plus leather, flexible white, or fluorescent materials, Dual; rigid materials plus garments, UV+DT. The materials do not replace the maintenance calculation: paying for and maintaining a second printhead is worthwhile only if you are going to use the workflow it unlocks.
