When choosing the right machine for production, nothing matters more than knowing which materials it can cut. I’ve seen clients invest in the wrong system simply because they didn’t understand this basic, critical fact.
Laser cutting machines can handle a wide range of materials—metals, plastics, wood, leather—but only if you choose the right type of laser for the right job.
If you're in procurement or production, especially in signage, fabrication, or industrial parts, choosing the right laser matters. The wrong match can waste time, money, and cause damage. Let's go through exactly what you can—and can't—cut.
What materials Cannot be cut on a laser cutter?
Some materials are not just unsuitable—they’re dangerous. I’ve seen cases where using the wrong material releases toxic fumes, damages the optics, or even causes fire. This is more than a performance issue. It’s a safety one.
PVC, polycarbonate, and some foam types should never be laser-cut because they release harmful gases or catch fire easily.
Why some materials are unsafe for lasers
Laser cutters work by burning or vaporizing the target material. When the material contains chemicals that react with heat, problems occur. For example:
| Material | Why it’s Unsafe | What Happens |
|---|---|---|
| PVC1 | Releases chlorine gas | Corrodes optics, damages lungs |
| Polycarbonate2 | Absorbs laser beam, not cuttable | Catches fire or melts unevenly |
| ABS plastic3 | Emits cyanide gas | Highly toxic fumes |
| Fiberglass | Contains resin and glass | Causes flare-ups and smoke |
| Styrofoam | Melts and burns quickly | Creates fire hazard |
At Kirin Laser, we always advise clients to avoid cutting these materials unless they’re using specialized equipment with fume extraction or alternatives like mechanical cutting.
Personal experience
One client came to us with recurring laser tube issues. They were unknowingly cutting thin polycarbonate for a lighting fixture project. The chlorine gas degraded their machine optics within weeks. We swapped their design with PETG—safe, clean, and effective. Their cutting jobs doubled in speed with no extra maintenance.
Can you laser-cut anything?
I get this question a lot, especially from new buyers. The answer is no. Laser machines are powerful tools, but they're not magic. The material—and the type of laser—matters more than people think.
You can’t cut everything with a laser, but you can cut a wide variety of materials if you match them to the right laser type.
Matching the laser to the material
There are three main types of laser cutting systems4: CO₂, fiber, and UV. Each one excels in different material categories:
| Laser Type | Best For | Examples of Materials |
|---|---|---|
| CO₂ | Non-metals | Wood, acrylic, glass, leather |
| Fiber | Metals | Stainless steel, aluminum, brass |
| UV | Soft, heat-sensitive materials | Plastics, ceramics, PCB boards |
I often explain it like this: a CO₂ laser5 is like a precise scalpel for organic and soft materials. A fiber laser is a powerhouse for metals. UV lasers are like delicate brushes for micro-scale work.
One time, a packaging manufacturer tried using a fiber laser6 to engrave cardboard. They wasted hours on poor results. Once we provided them with a CO₂ engraver, the cuts became clean and fast. Output quality improved, and their throughput increased by 3x.
Which of the following materials can not be laser-cut?
This is one of those trick questions that show how important technical knowledge is in procurement. Many people assume all plastics and foams are cuttable. That’s a costly mistake.
You cannot cut PVC, polycarbonate, or fiberglass with a standard laser cutter due to toxic emissions and fire risks.
Misconceptions and clarity
The confusion often comes from looking at the material's appearance, not its chemistry. Clear doesn’t mean safe. Soft doesn’t mean compatible.
Let’s break it down:
| Material | Safe to Cut? | Notes |
|---|---|---|
| Acrylic | Yes | Cuts cleanly with CO₂ laser7 |
| Polycarbonate | No | Doesn’t cut well; creates smoke and flames |
| PVC | No | Emits chlorine gas; extremely dangerous |
| Cardboard | Yes | Use CO₂ laser; proper ventilation needed |
| ABS | No | Melts and emits toxic fumes8 |
| Plywood | Yes | CO₂ laser works well; low resin content preferred |
| Leather | Yes | Use natural leather; avoid chrome-tanned types |
| Carbon fiber | No | Resin content causes burning and smoke |
These differences matter a lot when choosing machines or managing factory safety9. At Kirin Laser, our sales engineers often review client material lists before finalizing a machine recommendation. It’s part of our pre-sale support system.
What fabrics are safe for laser cutting?
This is especially relevant for clients in the fashion, interior, or textile signage industries. Not all fabrics are created equal—some burn, some melt, and some cut beautifully.
Natural fabrics like cotton, wool, silk, and polyester blends are safe for laser cutting with CO₂ machines.
Fabric types and laser compatibility
Fabrics respond to laser cutting based on their fiber type and weave tightness. Natural fibers tend to cut cleanly. Synthetics often melt or curl, but controlled power settings can reduce those effects.
Here’s a breakdown:
| Fabric | Laser Cuttable? | Notes |
|---|---|---|
| Cotton | Yes | Clean edges, slight browning |
| Wool | Yes | Cuts well but may smell during cutting |
| Silk | Yes | Delicate; use lower power settings |
| Polyester | Yes | Cuts clean; slight edge melting possible |
| Nylon | Limited | Tends to melt; test samples recommended |
| Spandex | No | High elasticity causes distortion |
| Felt | Yes | Excellent with CO₂ laser |
| Denim | Yes | Slight fraying; pre-wash for better results |
In our lab, we often test fabric swatches for clients before full production. One of our textile clients wanted to make custom curtains with laser-cut floral patterns. With just a 60W CO₂ laser10 and some airflow tuning, they produced high-end results at low cost.
Conclusion
Laser cutting11 is powerful and precise—but it’s not universal. Knowing what you can’t cut is just as important as knowing what you can. From metals with fiber lasers to fabrics with CO₂, the right match ensures clean results, long machine life, and workplace safety. At Kirin Laser, we help clients find that match through real-world testing, smart machine pairing, and tailored guidance. The result? Less trial and error. More results.
