What can a CO2 laser cut and engrave? A CO2 laser is the most versatile mainstream choice for non-metal fabrication. Its infrared wavelength works especially well with acrylic and many organic materials, including wood, paper, leather, fabric, cork and rubber. It can also create surface marks on glass, stone and coated metal.
That broad compatibility does not mean every material is safe or that every CO2 machine produces the same result. Tube power, optics, focus, air assist, exhaust, speed, material chemistry and thickness all affect the process.
See how laser air assist works before treating airflow as just another optional accessory.
Quick verdict: Choose a CO2 laser when clear acrylic, wood cutting, signs, packaging, leather or mixed non-metal production drives the purchase. It can engrave glass and mark some prepared or coated metals, but it is not the normal tool for direct engraving into bare metal. Never process PVC, vinyl or an unidentified plastic.
CO2 Laser Material Compatibility: Quick Comparison
| Material | Engrave? | Cut? | Important Limitation |
|---|---|---|---|
| Cast and extruded acrylic | Yes | Yes | Cast often engraves frosty; extruded often gives a clearer edge |
| Wood and plywood | Excellent | Yes | Resin, density and internal glue layers affect results |
| Paper and cardboard | Yes | Yes | High ignition risk requires constant supervision |
| Leather and fabric | Yes | Usually | Exact composition must be known and laser safe |
| Glass and stone | Surface mark | No | Thermal shock and chipping must be controlled |
| Rubber | Yes | Usually | Use laser-grade rubber with appropriate exhaust |
| Bare metal | Indirect or limited | No | A fiber laser is normally the correct direct-marking tool |

The P2S represents a modern desktop CO2 workflow. Its manufacturer lists a 55W source, a 23.6 × 12-inch work area, dual-camera positioning and passthrough support. Those features can reduce setup time, but material testing, extraction and supervision still determine safe production.
If you prefer a desktop CO2 machine with a guided workflow, compare two established approaches in our OMTech Polar 2 vs Glowforge Pro guide.
Acrylic: The Defining CO2-Laser Material
Acrylic is where CO2 separates itself most clearly from a standard blue diode. The 10.6 µm infrared output of a common CO2 tube is strongly absorbed by acrylic, including clear sheet. That makes it possible to cut transparent signs, displays, templates, awards and enclosures with polished-looking edges when focus and airflow are tuned correctly.
If you are considering a diode workaround instead, our guide to cutting clear acrylic with a diode laser explains why coatings help surface engraving but not dependable through-cuts.
Cast acrylic tends to produce a white, frosted engraving and is often preferred for engraved signage. Extruded acrylic often cuts with a smoother, clearer edge but may engrave less evenly. Both are sold simply as “acrylic,” so confirm the manufacturing type when the finish matters.
Our laser engraver settings for acrylic guide explains how to test these sheet types without relying on universal power numbers.
Thickness claims are not universal. Machine power, actual tube condition, focus, lens choice, airflow, speed, sheet formulation and required edge quality all affect whether a job should use one pass or several. For complete machine comparisons, see our best laser engraver for acrylic guide.
Before changing passes or speed, verify the focal plane with our laser focus guide.
Wood, Plywood and MDF
A CO2 laser engraves wood with high contrast and cuts sheet goods efficiently. It is well suited to signs, boxes, ornaments, furniture inlays, architectural models and production jigs. More output power can increase throughput, but the wood itself is often the limiting variable.
Dense hardwood may need lower speed than basswood. Resin produces darker edges and more deposits. Plywood can hide knots, glue pockets and voids that interrupt a cut. MDF is consistent but smoky and can contaminate optics rapidly. Use a small test piece from the actual batch before committing expensive stock.
For uneven or incomplete cuts, work through the material, focus, airflow, optics and alignment checks in diagnostic order.
If wood is the main revenue material, compare CO2 against high-power diode options in our wood laser guide. A CO2 platform normally earns its premium through faster cutting, clear-acrylic compatibility and a broader product catalog.
Paper, Cardboard and Packaging Materials
CO2 lasers can cut fine paper details, cardboard prototypes, cardstock invitations and packaging components. Low mass makes these materials fast to process—and fast to ignite. Keep the bed free of scraps, use only the energy needed for a clean cut and supervise every job.
Adhesive-backed stock requires extra care. The face material may be safe while the adhesive, liner or coating is not. Obtain composition information for every layer.
Leather, Fabric, Cork and Rubber
Natural leather can be engraved and cut into patches, tags and accessories. Fabric can be cut without mechanical fraying, while cork creates attractive dark engravings for coasters and mats. These materials all generate process emissions, so good extraction is part of the machine—not an optional accessory.
Only process rubber sold for laser engraving. Laser-grade stamp rubber is formulated for predictable ablation and is commonly used for stamps and seals. Unknown rubber can contain chlorine, sulfur compounds or fillers that create hazardous emissions and difficult residue.
Likewise, do not infer safety from the words “synthetic leather” or “vegan leather.” Some products contain PVC. Use supplier documentation to identify the polymer and all surface coatings before it enters the machine.
Glass, Ceramic, Slate and Stone
CO2 energy can create a visible surface mark on glass, ceramic tile, slate, marble and certain stone products. It does not cut these materials like acrylic. Glass engraving works by controlled micro-fracturing at the surface, which means excess heat can cause roughness, chips or cracks.
For bottles, glasses and other cylindrical blanks, use our laser rotary attachment guide to compare roller and chuck setups, calculate circumference and avoid seam or taper errors.
Use a lower-energy test matrix, keep artwork away from stressed edges and inspect every blank for damage. Rotary attachments make cylindrical glasses and bottles possible, but diameter, taper, clearance and fixture alignment must all be verified before processing.
Can a CO2 Laser Engrave Metal?
A conventional desktop CO2 laser does not directly engrave most bare metals efficiently. It can remove paint or anodizing, expose a contrasting coating, or create a bonded mark using a compatible metal-marking compound. These are useful workflows, but they are different from removing bare metal with a fiber laser.
If your product is stainless steel, aluminum, brass, jewelry or industrial identification, compare the technologies in our fiber vs CO2 guide. Buy CO2 for non-metal production and fiber for direct metal marking rather than expecting one source to excel at both.
CO2 Laser Power and Machine Size
| CO2 Range | Typical Fit | What to Check |
|---|---|---|
| Desktop 40W–60W | Crafts, signs, personalization and small-batch products | Usable bed, exhaust, cooling, object height and passthrough |
| Mid-power 60W–100W | Higher throughput and thicker compatible sheet | Electrical needs, chiller, footprint, optics and service access |
| Production 100W+ | Larger-format cutting and sustained business use | True rated output, duty cycle, fire control and commercial extraction |
Power does not substitute for work area. A small 55W machine may cut a material well but still reject the sign blank you need to sell. Measure the complete workpiece, including fixtures and rotary clearance. Check whether a passthrough accepts the width, thickness and feed method you expect.

Materials to Avoid in a CO2 Laser
Never process an unknown material. PVC and vinyl can generate corrosive and hazardous chlorine-containing compounds that threaten both people and equipment. The word “plastic” is not a usable identification, and a protective film or adhesive may be more problematic than the base sheet.
- PVC, vinyl and chlorine-containing materials: exclude them from the laser workflow.
- Unknown plastics and foams: obtain exact chemistry and safety documentation first.
- Fiberglass and many composites: resin fumes and reinforcing debris are difficult to control.
- Highly reflective or thick bare metal: a conventional CO2 craft laser is not the intended tool.
- Any flammable assembly with hidden layers: adhesives, cores and coatings must all be identified.
An enclosure helps capture smoke but does not make it disappear. Plan a short, sealed outdoor exhaust route or a properly specified filtration system. Our laser ventilation guide explains airflow, makeup air and filter limitations.
A Practical CO2 Material-Testing Process
- Confirm the exact material and every coating, adhesive or protective film.
- Check the machine manual and manufacturer material database for a starting range.
- Inspect the lens, mirrors, bed, cooling and exhaust before the test.
- Run a small speed-and-power matrix at conservative settings.
- Evaluate cut-through, kerf, edge finish, smoke staining and underside flare.
- Record the material batch, thickness, lens, focus and airflow with the winning setting.
- Repeat the test after changing supplier, color or thickness.
CO2 machines contain a powerful invisible beam, moving gantry and combustible material in an airflow path. Verify classification, interlocks and required controls for the exact product. Our Class 1 vs Class 4 guide explains why enclosure configuration matters.
Final Verdict
A CO2 laser is the most flexible choice for clear acrylic and mixed non-metal production. It can cut and engrave acrylic, wood, paper, leather, fabric, cork and laser-safe rubber, while also creating surface marks on glass, stone and coated items.
Its main boundary is bare metal. Prepared marks are possible, but direct metal engraving belongs to fiber. The safe workflow is equally non-negotiable: identify every material, exclude PVC and unknown plastics, provide effective exhaust and supervise every job.
Frequently Asked Questions
What materials can a CO2 laser cut?
A CO2 laser can cut acrylic, wood, plywood, paper, cardboard, leather, fabric, cork and suitable laser-grade rubber. Thickness and quality depend on power, focus, airflow, material chemistry, speed and pass count.
Can a CO2 laser cut clear acrylic?
Yes. Clear acrylic absorbs the infrared wavelength of a conventional CO2 laser, making CO2 the standard desktop choice for transparent acrylic cutting and engraving.
Can a CO2 laser engrave glass?
Yes, it can create a frosted surface mark through controlled micro-fracturing. It does not cut glass, and excessive energy can chip or crack the workpiece.
Can a CO2 laser engrave bare metal?
Not efficiently in the way a fiber laser can. A CO2 laser may remove a coating or bond a marking compound to metal, but direct bare-metal engraving is normally a fiber-laser job.
Is cast or extruded acrylic better for a CO2 laser?
Cast acrylic generally produces a stronger frosted engraving, while extruded acrylic often cuts with a smoother clear edge. Choose according to the desired finish and test the exact sheet.
What should never go in a CO2 laser?
Do not process PVC, vinyl, unidentified plastics or any material whose coatings and adhesives are unknown. Manufacturer approval and exact composition matter more than appearance.
