What can a CO₂ laser cut and engrave? The useful answer is not simply “wood, acrylic and leather.” A professional CO₂ laser can move between very different materials in the same production day, but each material has its own limits, finish, safety questions and process window. Some materials cut and engrave well. Others are suitable only for surface engraving or coating removal. Some should never enter the machine unless their composition has been positively identified.

For a business, that distinction matters. A material may be technically processable yet still be a poor production choice because the edge needs too much finishing, the engraving contrast is inconsistent, the stock varies from batch to batch, or the fumes demand a different extraction strategy.

Short answer: CO₂ lasers are particularly strong on acrylic, solid wood, suitable plywood and wood boards, natural leather, paper, cardboard, cork, many textiles and selected laser-compatible rubber and polymer products. They can also create surface engravings on glass, ceramics, slate and stone, and remove or alter suitable coatings on anodized or painted metals. A conventional AEON CO₂ laser should not be treated as a general-purpose bare-metal cutting or deep-metal-engraving system.

CO₂ laser materials: cut, engrave, mark or avoid?

The first rule is to separate four different outcomes:

• Cut: the beam passes through the material and creates a finished profile.
• Engrave: the beam removes or changes material at the surface to create visible depth, texture or contrast.
• Surface mark: the beam changes a coating, glaze, anodized layer or marking compound without cutting through the underlying material.
• Unsuitable: the material chemistry, fire behavior, reflection, fumes or process result make it inappropriate for the machine or application.

Those terms should not be used interchangeably. Removing powder coat from a tumbler is not the same process as deep engraving bare stainless steel. Frosting the surface of glass is not cutting glass. A CO₂ laser can produce useful commercial results on all three examples, but the mechanism and limitation are different.

This table is a compatibility map, not a settings chart. The same material family can contain grades that behave very differently. The exact result depends on composition, thickness, laser-source power, lens, focus, optical condition, air assist, extraction, geometry and the finish your customer will accept.

Why CO₂ laser material compatibility is not just about wattage

CO₂ lasers used for this type of production operate in the infrared around 10.6 μm. Many organic materials and polymers absorb that wavelength effectively, which is why one machine can cut acrylic, engrave wood, perforate card and mark glass without a physical cutting tool.

But absorption is only one part of the process. The material must also respond predictably to heat. A good production material should give an acceptable combination of edge quality, engraving contrast, dimensional accuracy, fumes, residue, cycle time and repeatability.

That is why a useful material test asks more than “did it cut through?” A part that separates from the sheet but leaves a badly melted lower edge, heavy soot, excessive taper or unstable dimensions is not necessarily a good production result.

Acrylic: one of the strongest CO₂ laser materials

Acrylic, or PMMA, is one of the clearest examples of why CO₂ technology is so useful in professional cutting and engraving. Clear acrylic absorbs CO₂ wavelength effectively, allowing transparent, colored and many specialty PMMA sheets to be processed without relying on visible pigment to absorb the beam.

That makes acrylic central to signage, displays, awards, lettering, retail fixtures, lightboxes, architectural models, templates, enclosures and fabricated products.

What result should you expect?

With suitable material and settings, CO₂ cutting can produce a smooth, polished-looking acrylic edge. Engraving can create a white or frosted contrast, particularly on cast acrylic. The quality target matters: a part that merely separates is not the same as a finished display edge.

Cast and extruded acrylic do not behave identically

Both are PMMA, but the manufacturing method changes the way the sheet responds. Cast acrylic is widely preferred when engraving contrast is important, while extruded acrylic often behaves differently under engraving and can produce a different cut edge. Pigment, mirror backing, impact modifiers, flame-retardant formulations and protective films add more variables.

Record the supplier and grade with the setting. “3 mm acrylic” is not enough information for a repeatable production recipe.

AEON factory acrylic data: useful information gain, not a universal preset

Our current acrylic settings guide publishes factory test data for CO₂ source powers from 25 W to 200 W and acrylic from 3 mm to 40 mm. The source data records both a factory-labelled best speed and a maximum speed at 95% power.

The table is valuable because it shows how quickly the useful speed window changes with thickness. It does not remove the need to test the actual sheet, lens, focus and machine condition.

Important: these are factory “best speed” references at 95% power, not guaranteed production presets. Use the complete acrylic chart for the full 25–200 W / 3–40 mm data and the explanation of best speed versus maximum speed.

Solid wood: excellent engraving, but every species has its own behavior

Wood is easy to describe as a laser material and surprisingly difficult to standardize. Oak, walnut, maple, beech, birch, pine, cedar, basswood and balsa do not share one density, resin content, moisture level or grain structure.

CO₂ engraving darkens and removes the surface, often producing excellent natural contrast without inks or physical tooling. Cutting creates detailed profiles with a narrow kerf, but the edge will normally show some degree of heat darkening.

What changes the result?

• Density: harder, denser species usually need more energy per millimeter than very light woods.
• Resin: resinous areas can darken differently and produce more smoke or deposits.
• Moisture: variable moisture affects cutting behavior and repeatability.
• Grain: engraving tone can change across earlywood and latewood in the same board.
• Surface finish: varnish, paint, oil or an unknown coating changes both safety and appearance.

For products such as signs, boxes, maps, furniture inlays, ornaments, puzzles, awards and personalized gifts, the wood itself becomes part of the visual result. That can be a strength, but it means production samples should use the real species and finish—not a generic “wood” test piece.

Plywood, MDF and HDF: treat the inside of the board as part of the material

Engineered wood is a major CO₂ laser application because it is flat, repeatable in size and easy to source. It is also a common source of misleading settings advice.

Plywood is not simply several layers of wood. Veneer species, glue, internal gaps, patches and fillers all affect how much energy is needed to complete a cut. A sheet can look identical on both faces and still contain a dense glue pocket that stops one section from cutting through.

MDF and HDF add binders and compressed fibers. They can engrave very evenly and cut into detailed shapes, but they often produce more smoke and fine residue than solid wood.

Production check for sheet goods

Before buying a large batch, test the exact board from the intended supplier. Cut a long contour, a tight inside corner and several small holes. Check the bottom edge—not only the top surface. If the same nominal board changes supplier or construction, treat it as a new material until the process is verified again.

For commercial work, this matters as much as headline cutting speed. A slightly slower setting that clears every internal glue line can cost less than a faster setting that creates intermittent rejects or manual recutting.

Leather: excellent results when the material really is leather

Natural leather cuts and engraves with strong detail and is widely used for wallets, belts, patches, notebook covers, bags, labels, keychains, guitar straps and personalized accessories.

Engraving normally creates a darker, recessed mark. Cut edges darken and can carry a noticeable odor, so extraction and post-cleaning are part of the workflow.

The important safety question is composition

Commercial names such as “faux leather,” “vegan leather” or “synthetic leather” do not tell you what polymer is present. Some synthetic leather products contain PVC or other chlorinated components and must not be processed in a CO₂ laser.

If the material is not natural leather, obtain the composition or safety data from the supplier before testing it. Appearance is not enough to identify chemistry.

Paper and cardboard: extremely precise, extremely easy to overheat

Paper-based materials are a natural fit for digital cutting because they require very little energy and can be processed without a blade dragging or compressing the sheet. Common products include invitations, packaging prototypes, folding structures, architectural models, stencils, hang tags, greeting cards and intricate paper art.

CO₂ lasers can cut, score, perforate and engrave many paper and board products, but thin stock also has very little thermal mass. Small offcuts and narrow bridges can ignite if heat accumulates or debris remains in the bed.

Judge more than the top edge

On packaging and presentation work, look at discoloration on both faces, smoke deposition, corner sharpness and fold behavior. Corrugated board adds flute structure and adhesives, so a recipe for solid card should not be copied automatically.

Keep the work area clean and never treat unattended operation as acceptable simply because the material is thin.

Textiles and fabrics: contact-free cutting changes the workflow

A CO₂ laser can cut many textiles without mechanical pressure, which is valuable for intricate patterns, appliqué, patches, apparel details, technical fabric parts and short-run customization.

The cut edge depends strongly on fiber chemistry. Natural fibers such as cotton and linen can show slight browning. Thermoplastic synthetic fibers may melt and seal at the edge, which can reduce fraying but can also create a harder bead if too much heat is used.

Felt, silk, denim, polyester, nylon and blended fabrics should not be treated as one settings family. Coatings, fire-retardant treatments, adhesives and laminations can matter as much as the visible fiber.

What to test

• edge sealing versus melting or hardening
• visible browning on light natural fabrics
• distortion on thin or stretchy material
• odor and extraction load
• engraving contrast after washing or handling
• repeatability across dyed or coated batches

Cork, bamboo and other plant-based materials

Cork and bamboo expand the same basic organic-material advantage into lightweight, commercially useful products. Cork engraves with strong contrast and can be cut for coasters, packaging inserts, seals, décor and promotional goods. Bamboo products and sheets can be used for signs, kitchen accessories, gift items and packaging.

Density and moisture still matter. Very dry or highly porous plant-based sheet can char or develop brittle edges more easily than a dense, consistent board. Laminated bamboo should be treated as a composite because the adhesive becomes part of the laser process.

Rubber, elastomers and foam: verify the chemistry first

Laser-compatible rubber sheets are useful for stamps, seals, gaskets, washers and custom flexible parts. CO₂ cutting is especially attractive when the geometry contains small holes, slots and curves that would be inconvenient to die-cut in short runs.

But “rubber” is a broad category. Natural rubber, silicone, EVA products, neoprene, NBR and specialist industrial elastomers do not share one chemistry or fume profile.

Some elastomers should not be laser processed at all. PVC-containing rubber products can release chlorine-containing gases. Fluoroelastomers such as FKM/Viton can release highly hazardous fluorine-containing decomposition products. Unknown gasket stock should therefore be treated as unknown chemistry until identified.

Even laser-compatible rubber can generate substantial smoke and odor. Extraction is not optional simply because the part cuts cleanly.

Plastics: never use the word “plastic” as a material specification

Acrylic demonstrates that CO₂ lasers can be excellent polymer-processing tools. It does not mean every plastic belongs in the machine.

Different polymers absorb, melt, char and decompose in very different ways. Some suitable technical plastics can be cut or marked cleanly; others produce poor edges, heavy soot, flame or hazardous gases. Additives, flame retardants, fillers and coatings make identification even more important.

Materials that require an immediate stop before testing

PVC, vinyl and other chlorinated polymers are unsuitable for CO₂ laser processing. They can release corrosive and hazardous chlorine-containing gases. PTFE and other fluorinated materials, including some fluorinated elastomers, also require strict avoidance because of hazardous decomposition products.

For an unknown plastic, the correct test is not “try low power.” The correct first step is to identify the resin and any coating or additive through supplier documentation or the safety data sheet.

Why supplier identification matters commercially

If a plastic part will become a repeat product, record the exact grade. A successful sample made from one transparent sheet does not prove that another clear polymer from a different supplier is PMMA or will behave the same way.

Glass: engrave the surface, do not treat it as a cutting material

CO₂ lasers are widely used to create a frosted surface effect on compatible glass. Drinkware, bottles, awards, mirrors, architectural glass and decorative products can all be candidates for engraving, often with a rotary attachment for cylindrical work.

The mark comes from a localized surface interaction rather than a conventional through-cut. The exact appearance depends on glass composition, thickness, curvature and thermal stress.

What to inspect in a glass test

• micro-chipping around fine detail
• uneven frosting
• thermal cracking
• contrast against the final background
• distortion on cylindrical products

Do not assume every glass product will tolerate the same process. Heat-treated, coated, mirrored and specialty glass should be evaluated separately.

Ceramics and tile: surface interaction, not through-cutting

CO₂ lasers can create useful surface marks on many ceramic products, including tiles, mugs, stoneware and decorative pieces. Depending on the glaze and substrate, the laser may alter or remove the surface finish and reveal a contrasting layer beneath.

The process should be described as engraving or surface marking, not cutting. Metallic or reflective glazes, specialty technical ceramics and unknown coatings require separate evaluation.

For commercial products, test the actual glaze batch. Two white ceramic mugs can use different coatings and produce visibly different contrast from the same file.

Stone, slate, brick and other mineral materials

Natural inorganic materials are normally surface-engraving applications. Slate, marble, granite, sandstone, basalt, pebbles, brick and some shell or mineral products can develop a permanent contrasting mark without mechanical contact.

The attraction is customization without tool wear. The limitation is natural variation. A photograph engraved on one slate batch may not match another because mineral composition, color and surface texture change.

Dust is part of the process

Mineral engraving can create fine particulate matter. Extraction, filtration and cleanup should be chosen for the material, especially where silica-bearing stone is involved. “No toxic plastic fumes” does not mean “no airborne hazard.”

Metal: distinguish coating removal, bonded marking and direct engraving

Metal is one of the areas where CO₂ laser language becomes misleading very quickly. A conventional AEON CO₂ platform is not a sheet-metal cutter and should not be described as a general-purpose deep engraver for bare stainless steel, aluminum, copper or brass.

Coated and anodized metal

Anodized aluminum, painted metal and powder-coated products can be excellent CO₂ applications because the beam changes or removes the surface layer. Common products include tumblers, nameplates, control panels, tags, promotional items and branded hardware.

Bare metal with a marking compound

Selected bare metals can be marked using a compatible laser-marking compound. The compound is applied before processing and bonds to the surface under laser energy, creating a durable visible mark.

This is commercially useful for identification and decoration, but it is still a surface-marking process. It should not be described as direct deep engraving into the metal.

When fiber is the correct answer

If the business depends on direct engraving of bare metals, serial marking without a coating or compound, or cutting metal sheet, compare the appropriate fiber-laser technology instead. A fiber marker and a flatbed fiber cutting machine are themselves different categories, so match the process to the finished part.

Composites and laminates: the most important question is “what is inside?”

Composite materials should not be flattened into one compatibility category. A composite can contain wood fiber, paper, resin, textile reinforcement, glass fiber, carbon, metal pigment, adhesive, foam or several coatings in the same sheet.

Some combinations are excellent CO₂ materials. Plywood, MDF and many paper-based laminates are everyday examples. Others are suitable only for surface marking, and some are inappropriate because the binder or reinforcement creates hazardous fumes, fiber release, unpredictable absorption or poor edge quality.

Examples that require different treatment

• Wood-based boards: cutting and engraving can work very well, but glue and filler affect consistency.
• Paper / polymer laminates: verify every polymer and coating before cutting.
• Fabric- or leather-laminated products: both the visible layer and adhesive must be identified.
• EVA and gasket composites: some formulations can be useful; others contain unsuitable additives.
• Glass-fiber-reinforced polymer: treat as a specialist material; current materials guidance limits this category to surface engraving rather than through-cutting and calls for appropriate ventilation and particulate control.
• Carbon-filled or metal-pigmented boards: absorption can become irregular and the process should not be assumed from the base polymer alone.
• PVC- or chlorinated laminates: unsuitable.

If the supplier cannot state the binder, reinforcement and coating, do not invent a process from appearance.

Materials that should not go into a CO₂ laser without positive identification

A “do not laser” list is useful, but it is not a substitute for composition data. Trade names change, formulations change, and many sheet products are laminated.

At minimum, stop before processing:

• PVC and vinyl
• chlorinated plastics and coatings
• unknown synthetic leather
• unknown foams
• PTFE / fluoropolymer products
• FKM / Viton and unidentified industrial elastomers
• unknown composites and laminates
• materials with unidentified flame-retardant, metallic or chemical coatings

For an unfamiliar industrial material, obtain a safety data sheet or written composition from the manufacturer. The correct question is not only whether the laser can put a mark on it, but whether the process is safe for the operator, extraction system, optics and machine.

How thick can a CO₂ laser cut?

There is no meaningful universal thickness answer because “CO₂ laser” and “material” are both too broad.

Ten millimeters of acrylic, ten millimeters of hardwood and ten millimeters of plywood do not require the same energy, lens, airflow or quality standard. The same nominal thickness can also vary in actual measurement and formulation.

Cutting capacity is influenced by:

• rated source power and actual delivered optical power
• material type, density, color and formulation
• actual thickness
• lens focal length and focus strategy
• optical cleanliness and beam delivery
• air assist
• extraction
• part geometry
• single-pass versus multi-pass strategy
• the edge finish and dimensional tolerance required

For acrylic, our published factory data provides a controlled reference because both rated source power and sheet thickness are defined. For other materials, build a test around the actual stock rather than borrowing an acrylic thickness claim.

How to test a new CO₂ laser material properly

A disciplined material test is one of the simplest ways to improve both safety and profitability. It turns a one-off success into a repeatable production recipe.

1. Identify the material completely. Record supplier, grade, composition, nominal thickness, measured thickness, coating, adhesive and protective film.
2. Confirm that the chemistry is suitable. Check supplier documentation or safety data before the material enters the machine.
3. Define the required result. Decide whether the goal is a finished cut edge, engraving contrast, surface mark, dimensional fit or simply separation.
4. Start from a controlled reference. Use verified settings data where available, then test a narrow range around it.
5. Change one variable at a time. If power, speed, focus and air assist all change together, the test cannot tell you what solved the problem.
6. Use real geometry. Include a long line, curve, corner, small opening and representative engraving rather than testing only a short straight cut.
7. Inspect both sides. Check upper and lower edge, kerf, soot, melt, taper, discoloration, dimensional accuracy and residue.
8. Repeat the test. One successful part is not yet a production setting.
9. Save the complete recipe. Store material, supplier, batch, lens, focus, power, speed, airflow, date and acceptance notes.

A useful production acceptance checklist

Choose a CO₂ laser around the materials and products you actually sell

Material compatibility tells you whether CO₂ is the right technology. It does not tell you which machine size, source type or production platform will make the business efficient.

Start with five real products. For each one, record:

• material and thickness
• finished dimensions
• incoming sheet or blank size
• quantity per order
• percentage of machine time spent cutting versus engraving
• whether a rotary is required
• acceptable edge or engraving finish

MIRA S: compact professional mixed-material production

MIRA S is the natural fit when professional cutting and engraving must stay within a compact workshop footprint. The family is suited to personalized products, signs, awards, packaging prototypes, smaller fabricated parts and repeat mixed-material work.

Current global configurations cover three working areas: MIRA5 S at 500 × 300 mm, MIRA7 S at 700 × 500 mm and MIRA9 S at 900 × 600 mm. Glass-source and RF-source configurations answer different priorities, so choose around the balance between cutting and detailed engraving rather than around bed size alone.

NOVA Elite: larger sheet work and cutting-led production

NOVA Elite becomes more relevant when incoming sheet size, nesting efficiency and larger finished products are the main constraints. Current global family sizes extend through 1000 × 700 mm, 1400 × 900 mm and 1600 × 1000 mm working areas.

For a business cutting larger acrylic, plywood, rubber or other compatible sheet materials, fitting more accepted parts into each cycle can matter more than a higher engraving-speed headline.

Super NOVA: cutting and fast RF engraving in one large-format workflow

Super NOVA combines a glass CO₂ source and an RF CO₂ source in one machine. The glass source supports cutting-led work, while RF supports fast, detailed engraving. Both are CO₂ sources; Super NOVA is not a fiber-laser machine.

This architecture matters when the same shop sells both substantial cut products and high-detail engraving. It can reduce the compromise of asking one source type to dominate both workflows.

Material choice changes production economics

The cheapest sheet is not automatically the cheapest finished part. Material choice affects:

• cutting or engraving time
• parts per sheet
• edge finishing
• cleaning time
• reject rate
• extraction load
• fixture requirements
• packaging and handling
• repeatability from batch to batch

A premium laser-grade plywood that cuts consistently can be cheaper in production than a lower-cost board that contains random glue pockets. An acrylic setting that leaves a customer-ready edge can be more profitable than a faster cut that needs hand polishing. A textile that seals cleanly at the edge can eliminate a secondary operation.

For business decisions, measure accepted products per hour—not only millimeters per second.

What can you make with a CO₂ laser?

Frequently asked questions about CO₂ laser materials

What materials can a CO₂ laser cut?

Common compatible cutting materials include acrylic, suitable wood and plywood, MDF, natural leather, paper, cardboard, cork, many textiles and selected laser-compatible rubber and polymer products. The exact capability depends on composition, thickness, source power, lens, focus, airflow and the required finish.

What materials can a CO₂ laser engrave?

CO₂ lasers can engrave many of the materials they cut and can also create surface marks on glass, ceramics, stone, slate and suitable coated or anodized metals.

Can a CO₂ laser cut clear acrylic?

Yes. Clear PMMA absorbs CO₂ wavelength effectively, which is why clear signs, displays, awards and fabricated acrylic products are major CO₂ laser applications.

Can a CO₂ laser cut metal?

Conventional AEON CO₂ systems covered by this guide are not sheet-metal cutting machines. They can remove suitable coatings from metal surfaces and can create bonded marks on selected bare metals with an appropriate marking compound. Direct bare-metal cutting belongs to a different machine category.

Can a CO₂ laser engrave stainless steel?

It can remove a suitable coating or use a compatible marking compound to create a bonded surface mark on selected stainless steel. That should not be confused with direct deep engraving into bare metal. Use the appropriate fiber-laser process when direct metal removal is required.

Can a CO₂ laser cut glass?

No, not with the standard AEON platforms covered here. Glass is normally a surface-engraving application that creates a frosted or matte effect.

Can a CO₂ laser cut any plastic?

No. Polymer chemistry must be identified first. Acrylic is an excellent CO₂ material, but PVC, vinyl, chlorinated products and fluorinated materials can create hazardous and corrosive decomposition products. Unknown plastics should not be tested until their composition is confirmed.

Can a CO₂ laser cut plywood?

Yes, suitable plywood is a common CO₂ material. However, veneer species, adhesive, internal voids and fillers affect both cut quality and repeatability. Test the exact board you intend to buy in production quantities.

Why does the same setting behave differently on two sheets?

Nominal material name and thickness are only part of the process. Density, moisture, pigment, additives, adhesive, coating, actual thickness, sheet flatness, lens, focus, optic condition and airflow can all change the result.

How do I know whether an unknown material is safe to laser?

Identify the exact composition through the manufacturer or supplier documentation before processing. If the composition is unknown, do not use the laser as the identification test.

How thick can a CO₂ laser cut?

There is no single universal number. Thickness capability depends on the material, source power, lens, focus, airflow, optical condition and required edge quality. Use material-specific reference data and verify the exact stock.

Which AEON laser is best for mixed materials?

Choose by the products and bottleneck rather than by the number of materials. MIRA S fits compact professional mixed-material production. NOVA Elite fits larger sheet and cutting-led workflows. Super NOVA is designed for shops that need larger-format glass-source cutting and fast RF engraving in the same platform.

Start with the material, then choose the machine

A compatibility list is only the beginning. The useful buying question is: what materials, thicknesses, sheet sizes and finished products will you process repeatedly?

Bring those real materials into the machine-selection process. Test the actual acrylic grade, plywood, leather, textile or coated product that will become part of your catalog. Compare the edge, engraving contrast, cycle time, nesting, cleaning and repeatability—not only whether the beam can make a mark.

That is how a materials list becomes a production decision.
