ComMarker Omni 1 Review: The UV Laser That Can Engrave Almost Anything
There's a laser technology that genuinely does something none of the others can: engrave glass cleanly, mark clear acrylic without coating, cut felt without charring edges, and produce deep black marks on stainless steel — all without preparation sprays, heat damage, or fumes. That technology is UV (ultraviolet) laser at 355nm, and the ComMarker Omni 1 is one of the most accessible ways to put it on your workbench.
This review is grounded in hands-on testing data from multiple independent sources, including Hobby Laser Cutters, ComMarker's own reviewer community, and Tom's Hardware's coverage of the broader Omni series. It covers what UV laser technology actually does differently, how the Omni 1 performs across its full material range, and where it has real limitations.
Who the Omni 1 Is Built For
The Omni 1 is built for makers who need to work across the widest possible material range from a single machine — and who specifically need to engrave materials that standard diode and fiber lasers handle poorly or not at all.
Glass engraving is the signature use case. If your business includes custom glassware, wine glasses, glass tumblers, crystal gifts, or glass ornaments, the Omni 1 is the most capable and accessible machine available for this work at a desktop scale. No CO2 laser is needed, no Cermark spray, no frosting compound — the UV beam creates a clean frosted mark directly on the glass surface.
It's also a strong fit for electronics and plastics work. PCB marking, coated component labeling, ABS and polycarbonate engraving, and marking heat-sensitive plastics that standard lasers melt or discolor all fall within the Omni 1's capability set. For small businesses that make custom 3D-printed products, the UV laser marks PLA and PETG cleanly in a way no other desktop laser can.
More broadly, if you've hit the ceiling of what a diode or fiber laser can do for your material range, and you want one machine that genuinely covers everything from metal to glass to leather to paper to ceramics — the Omni 1 is that machine.
Unboxing and Setup: First Impressions
The Omni 1 ships in three main sections: the base, the tower column, and the laser head assembly. Assembly is just eight screws total — four for the column to the base, four for the laser head mount. Most users are set up and running their first test within 30–45 minutes of opening the box.
The included accessories are comprehensive: safety goggles, a foot pedal, a ruler for manual focusing, an electric lifting table, and two field lenses (150mm and 70mm). The USB drive includes EZCAD2 software and a pre-loaded parameter library for common materials. At 23.5kg, the machine is a dedicated desktop unit — not portable in the way a 6.5kg compact fiber laser is, but manageable on a standard workbench.
One important first-use note: UV lasers don't have a traditional power percentage setting. Engraving power is controlled by frequency and Q-pulse parameters. A smaller Q-pulse value delivers stronger individual pulses; higher frequency emits more pulses per second. A few test passes on scrap material to calibrate are essential before running your first real job.

5W vs 10W: Which Should You Choose?
For most glass engraving, standard plastics, coated metals, and wood — the 5W version is fully capable and easier to dial in. The 10W engraves significantly deeper and cuts thicker materials (12mm basswood vs 8mm, 10mm acrylic vs 6mm, 1.2mm stainless vs 0.6mm). One counterintuitive finding: the 5W sometimes produces smoother surface marks on stainless steel because its lower minimum power is easier to calibrate on delicate surfaces. For most buyers, the 5W is the recommended starting point. Our dedicated 5W vs 10W UV laser guide covers this comparison in full.
Real-World Material Testing
Glass: The Signature Application
Glass is where the UV laser does something no other affordable desktop laser can match. The 355nm wavelength is absorbed by glass (unlike CO2 and fiber lasers, which pass through it), allowing direct engraving without thermal cracking. The result is crisp, frosted marks on wine glasses, tumblers, glass ornaments, and crystal items. With the 70mm lens, the Omni 1 can create embedded engravings inside the glass itself — a 3D effect that looks like it was made by industrial equipment costing tens of thousands of dollars. Our guide to UV laser engraving on glass covers settings and techniques in depth.
Plastics and Electronics
UV's photochemical cold processing breaks molecular bonds without generating significant heat, producing clean marks on ABS, polycarbonate, PET, nylon, silicone, rubber, and PCB substrates without surface damage. For 3D printed parts, the Omni 1 marks PLA and PETG cleanly in a way no diode or fiber laser can.
Metals, Wood, and Leather
On coated, plated, and anodized metals, the UV laser excels — removing coatings precisely without damaging the substrate. On bare stainless steel, it produces high-contrast black marks that reviewers describe as superior to standard fiber laser results. Wood engraves with exceptional cleanliness — no smoke stains, no char halo. Leather is similarly clean, with no burn-through on thin pieces and no melting at cut edges. Felt cuts with scalpel-like precision.
What the Omni 1 Does Better Than Any Other Laser at Its Price
Direct glass engraving without thermal cracking. CO2 lasers crack standard glass. Diode and fiber lasers pass straight through it. The UV laser at 355nm is the only desktop option that engraves glass cleanly.
Clear acrylic and plastic marking without coating. Standard lasers require Cermark or marking spray. The UV beam marks them directly.
Heat-sensitive material marking. PCBs, flexible circuits, thin polymers, and coated components that fiber or CO2 lasers damage are safely marked by the UV cold process.
Embedded glass engravings. Using the 70mm lens focused below the glass surface, the Omni 1 can create 3D internal engravings inside glass blocks — normally associated with industrial systems costing $15,000+.
Clean wood engraving with zero smoke staining. For high-end gift products where visual presentation matters, the UV laser's smoke-free wood output is a product quality advantage customers notice.
Limitations to Know Before You Buy
No built-in enclosure. UV light at 355nm is particularly harmful to eyes and skin. Safety glasses are included and essential. For shared workspaces or customer-facing environments, a separate enclosure is strongly recommended.
Weight. At 23.5kg, the Omni 1 is a dedicated desktop machine. Not portable.
Not ideal for deep bare metal engraving. For aggressive material removal on uncoated stainless or aluminum, a dedicated fiber laser is the better tool.
Power control learning curve. Frequency/Q-pulse control instead of a standard power slider takes adjustment — expect a few hours of parameter testing before running production jobs confidently.
ComMarker Omni 1 vs Omni X: The Key Upgrade Decision
The Omni X adds a fully integrated enclosure (Class 1), LiDAR autofocus, a slide extension expanding the work area to 150 × 400mm, and true 3D crystal engraving via motorized Z-axis. It starts at around $4,600 — roughly 4.5x the Omni 1's starting price. For buyers who need the enclosed design, LiDAR autofocus, or 3D crystal engraving, the Omni X upgrade makes sense. For buyers who want the most cost-effective entry to UV laser technology for glass and multi-material work, the Omni 1 delivers the core capabilities at a fraction of the cost. For a full breakdown, see our ComMarker Omni 1 vs Omni X guide.

Final Verdict
The ComMarker Omni 1 earns its reputation. For the specific materials it's built for — glass, clear plastics, coated metals, heat-sensitive electronics, and ceramic — it delivers professional-grade results that no other desktop laser type can match. The combination of 0.0019mm spot size, 16K HD resolution, and UV cold processing produces engraving quality that regularly surprises users accustomed to diode and fiber systems. The limitations are real, but for a business built on glassware personalization, multi-material custom gifting, or electronics marking, those limitations are either irrelevant or easily managed.
Frequently Asked Questions
What is the ComMarker Omni 1 and what makes it different from other laser engravers?
The ComMarker Omni 1 is a UV galvo laser engraver at 355nm, available in 5W and 10W versions. Unlike diode, fiber, or CO2 lasers, UV interacts with materials through photochemical cold processing — breaking molecular bonds rather than burning. This enables glass engraving without cracking, clear acrylic marking without spray, heat-sensitive material marking without damage, and very fine detail thanks to the 0.0019mm spot size.
Can the ComMarker Omni 1 engrave glass?
Yes — glass engraving is the Omni 1's signature capability. The 355nm wavelength is absorbed by glass, enabling direct frosted surface engraving without thermal cracking. With the 70mm lens focused below the surface, it can also create embedded internal engravings inside thick glass blocks.
What is the difference between the 5W and 10W ComMarker Omni 1?
The 10W engraves deeper and cuts thicker materials (12mm basswood vs 8mm, 10mm acrylic vs 6mm, 1.2mm stainless vs 0.6mm) and is liquid-cooled. The 5W sometimes produces smoother surface marks on stainless steel due to its lower minimum pulse energy. For most glass, plastics, and wood work, the 5W is fully capable and the recommended starting point.
Does the ComMarker Omni 1 require an enclosure?
The Omni 1 is an open-frame Class 4 machine. UV light at 355nm is invisible and more hazardous than visible-light lasers. Safety glasses are included and essential. For shared workspaces or customer-facing environments, an enclosure is strongly recommended. For a private, controlled workspace with consistent PPE, the open frame is workable.
What software does the ComMarker Omni 1 use?
The Omni 1 supports EZCAD2 (included with material parameter library) and LightBurn via the LightBurn Galvo plugin (sold separately). Most users prefer LightBurn for its intuitive workflow and strong community support.
Can the ComMarker Omni 1 engrave metal?
Yes, with caveats. On coated, plated, and anodized metals it excels — removing coatings precisely without damaging the substrate. On bare stainless steel, it produces clean high-contrast black marks. For deep engraving on bare metal at production volume, a dedicated fiber laser is more appropriate.
How does the ComMarker Omni 1 compare to the Omni X?
The Omni X adds a fully integrated Class 1 enclosure, LiDAR autofocus, motorized Z-axis for true 3D crystal engraving, and an optional slide extending the work area to 150 × 400mm. It starts at approximately $4,600 versus the Omni 1's $999 starting price. Our Omni 1 vs Omni X comparison guide covers every difference in detail.
