If you're new to laser engraving or thinking about buying your first machine, you're probably asking the same question everyone asks: what can a laser engraver cut? It's one of the most common questions I get from beginners, and honestly, it's also one of the most important. The right material makes or breaks your project, and using the wrong one can even be dangerous.
After years of running a small laser engraving business, I've cut and engraved just about everything you can think of. In this guide, I'll break down exactly what materials a laser engraving machine can cut, what it can't, and share my go-to power settings for each. Let's dive in.
How Laser Engraving and Cutting Works
Before we get to the material list, let's quickly cover the basics. A diode or CO2 laser works by focusing a high-powered beam of light that heats and vaporizes the material where it hits. Engraving removes a thin layer from the surface to create your design, while cutting goes all the way through.
Different laser types handle different materials: - Diode lasers (most common for beginners): Great for wood, plastics, fabric, leather - CO2 lasers: Work on just about everything non-metallic, can cut thicker materials - Fiber/galvo lasers (like the Tyvok P2): Perfect for metals, coated materials, and high-speed engraving
Now let's break down each material category by category.
Woods: The Most Popular Laser Material
Wood is hands-down the most common material for laser engraving projects, and for good reason—it looks amazing, it's easy to work with, and almost any laser can handle it.
Can You Cut Wood with a Laser?
Absolutely. Both softwoods and hardwoods work great for both cutting and engraving.
- Softwoods (pine, cedar, balsa): Easy to cut, even with lower-powered lasers. Engraves beautifully with nice contrast. The only downside is they can burn more easily, so go slower if you want clean edges.
- Hardwoods (oak, maple, walnut): Can be cut, but you'll need higher power (50W+ for cutting). Engraving gives fantastic contrast—dark against the natural wood looks incredible.
- Plywood: One of my favorites for projects like signs and coasters. Just make sure it's pure plywood without toxic adhesives. Some cheaper plywoods use formaldehyde-based glues that release fumes when cut.
- MDF: Cuts very cleanly and is great for practice. It does produce more dust than solid wood, so make sure your ventilation is good.
Recommended power settings (for 50W diode laser): - Engraving: 30-50% power, 200-300 mm/s speed - Cutting (1/4" wood): 70-100% power, 10-20 mm/s speed
Pro tip: Always do a small test burn first. Different woods have different densities and moisture contents, which changes how they react to the laser.
Plastics: Versatile but Pick Your Type
Plastic is another popular material, but you need to be careful—not all plastics are laser-safe.
Can You Cut Plastic with a Laser Engraver?
Some plastics work great, others are dangerous. Here's what to look for:
Safe Plastics for Laser Cutting/Engraving
- Acrylic (Plexiglass): This is the plastic I cut the most. It cuts incredibly clean with a polished edge right out of the machine. It engraves to a beautiful matte white finish that really pops. Perfect for signs, keychains, and displays.
- Delrin (Acetal): Cuts very cleanly with no mess and produces very little odor. Great for mechanical parts and jigs.
- ABS: Can be cut, but it does produce a strong odor. Good ventilation is a must.
- Polycarbonate (thin): Thin polycarbonate can be cut with higher-powered lasers, but thicker sheets tend to melt rather than cut cleanly.
Recommended power settings (50W laser): - Acrylic (1/8"): Engraving 30-40% power, 300 mm/s speed; Cutting 80-100% power, 15-25 mm/s speed
Plastics to Avoid
The big one you need to avoid is PVC (polyvinyl chloride). When you cut PVC, it releases chlorine gas which is toxic and will also corrode your laser machine. Never cut PVC with a laser.
Also avoid any vinyl that has chlorine in it—most cheap adhesive vinyl falls into this category.
Metals: What You Need to Know
Here's where things get interesting. A lot of beginners think lasers can't cut metal, but that's not the whole story.
Can a Laser Engraver Cut Metal?
For the most part, regular diode and CO2 lasers under 100W can't cut through thick metal. But they can engrave many coated metals, and fiber galvo lasers can cut thin metals easily.
- Anodized aluminum: This is one of my favorite materials for laser engraving. The laser removes the colored anodized coating to reveal the bare aluminum underneath, creating a beautiful high-contrast mark that won't wear off. Galvo lasers like the Tyvok P2 absolutely shine here—they can engrave anodized aluminum at incredible speeds with perfect precision.
- Stainless steel: Similar to anodized aluminum, you can engrave stainless steel with a fiber laser. You can even get good results with a high-powered diode using a laser marking spray. Again, galvo lasers like the Tyvok P2 do amazing work here for things like metal tags, jewelry, and custom gifts.
- Powder-coated metals: Just like anodized aluminum, the laser removes the coating to create your design. Works great for tumblers, water bottles, and tool handles.
- Thin metal sheets (aluminum, steel): High-powered fiber lasers can cut thin sheets (under 1mm) easily. Most desktop diode lasers can't handle thick metal cutting, but new higher-powered models are starting to change that.
Recommended settings for galvo laser on anodized aluminum: - 30-50% power, 500-1000 mm/s speed for engraving
Pro tip: Always use air assist when engraving metal to keep the surface clean and prevent discoloration.
Glass: Engraving Yes, Cutting No
Glass is a popular material for custom gifts like wine glasses, bottles, and awards—but what can you actually do with it?
Can You Cut Glass with a Laser?
For desktop laser machines, cutting glass is not really practical. The laser tends to cause micro-cracks that can make the glass shatter. That said, laser engraving glass works great with the right technique.
When you laser engrave glass, the rapid heating causes a controlled crack on the surface, which gives you a frosted effect that looks amazing. The key is to: - Use low power (10-30% on a 50W laser) - Go slow - Do multiple passes rather than one high-power pass - Keep the glass cool—some people even put it in a bucket of water while engraving
I've done hundreds of wine glasses and whiskey bottles this way, and they always come out looking great. Just don't expect to cut a full sheet of glass with your desktop laser—it's not worth the risk.
Stone and Concrete: Engraving Works Great
Stone is another material that surprises people. You can't really cut thick stone with a desktop laser, but you can absolutely engrave it.
Can a Laser Engrave Stone?
Yes, it works really well for things like: - Granite memorial plaques - Stone coasters - Concrete garden decorations - Marble gifts
The laser vaporizes a tiny layer from the surface, creating a permanent dark mark that won't fade. The denser the stone, the better the contrast.
Settings for 50W laser: 40-60% power, 100-200 mm/s speed, multiple passes for deeper marks.
The main downside is that stone creates a lot of fine dust, so make sure you have good ventilation and wear a dust mask when cleaning your machine afterward.
Fabrics and Textiles: Perfect for Custom Projects
Fabric is actually one of the most underrated materials for laser cutting. If you're into sewing, quilting, or making custom apparel, a laser can be a game-changer.
Can a Laser Cut Fabric?
Absolutely, and it does an amazing job. The best part is that the laser actually seals the edges as it cuts, so most fabrics won't fray.
Great fabrics for laser cutting: - Cotton: Cuts cleanly, no fraying. Perfect for patches, appliqué, and quilt pieces. - Polyester: Works great, just watch the heat—polyester melts easily, so use lower power. - Leather and faux leather: One of my favorites for leather keychains, bracelets, and patches. Cuts beautifully and engraves with nice contrast. - Felt: Cuts extremely cleanly, no fraying at all. Perfect for banners and decorations. - Denim: Great for custom patches and jackets. Cuts well and the edges hold up.
Recommended settings (50W laser): - Cutting thin fabric: 30-50% power, 50-100 mm/s speed - Engraving leather: 20-40% power, 200-300 mm/s speed
Pro tip: Always test first. Some synthetic fabrics melt and can leave a sticky mess on your honeycomb bed. Natural fabrics are almost always safer.
Paper and Cardstock: Great for Stencils and Invitations
If you need to do intricate paper cutting for invitations, stencils, or paper crafts, a laser engraver is perfect.
Can You Cut Paper with a Laser?
Yes, and it can cut incredibly intricate designs that would be almost impossible by hand. The laser cuts cleanly through even thick cardstock.
- Cardstock: Perfect for wedding invitations, greeting cards, and paper crafts.
- Cardboard: Great for making prototypes, boxes, and stencils.
- Veneer paper: Thin wood veneer paper works amazing for inlays.
Settings (50W laser): 20-40% power, 100-200 mm/s speed. Use multiple passes if it's not cutting all the way through—lower power gives cleaner edges than high power which can burn.
Other Materials That Work
There are plenty of other materials that work great with laser cutters: - Rubber: Perfect for making custom stamps. Engraves really well. - Cork: Cuts and engraves beautifully. Great for coasters and wall art. - Wax: Can be engraved for custom molds. - Bamboo: Just like hardwood—cuts and engraves great. - Corrugated cardboard: Easy to cut, great for packing projects.
Materials That Are Unsafe to Laser Cut
This section is critical—using the wrong material can release toxic fumes that are dangerous for you and can damage your machine. Never laser cut these materials:
- PVC (polyvinyl chloride): Releases toxic chlorine gas and corrodes your laser. Avoid at all costs.
- Vinyl (most types): Most vinyl contains PVC—check before you cut.
- Polypropylene with chlorine additives: Some plastics have chlorine additives, check the material safety data sheet if you're unsure.
- Treated wood with toxic chemicals: Pressure-treated wood can release toxic fumes when burned.
- Any material that contains fluorine: Teflon and similar materials release toxic fumes.
When in doubt, don't cut it. Do a small test in a well-ventilated area if you're unsure, and always have good ventilation running when you're cutting anything new.
