You can laser engrave wood, acrylic, glass, leather, coated metals, and certain stainless steel products — and within each of those categories, the results vary based on the material grade, thickness, and surface finish. I'm Veronica Ramirez, and I run a Thunder Nova 51 CO₂ laser out of Estero, Florida. Here is a complete, honest answer to the question I get asked most.
The Short Answer: More Than Most People Expect
The longer I've been doing this, the more I've learned that the better question isn't "can you engrave this?" — it's "what will it look like, and will it hold up?" Some materials engrave beautifully and last decades. Others are technically engravable but produce results that don't match what the customer imagined.
Here's a breakdown of what I work with regularly at Palm Coast Customs, what the results look like, and what the limitations are.
Wood
Wood is where laser engraving looks most natural and is easiest to love.
Best results: 3mm Baltic birch plywood, hardwood blanks (maple, walnut, cherry), MDF, bamboo. The Thunder Nova 51 burns a high-contrast dark mark into the wood grain. On Baltic birch, the engraving is crisp with almost no grain interference. On walnut, you get a warm, rich contrast that looks expensive immediately. On maple, the engraving is golden-brown against a pale background — clean and classic.
What it's used for: Family name signs, cutting boards, business signs, awards, plaques, home décor, keepsakes, baby announcement boards, real estate closing gifts.
What to know: Softwoods engrave quickly but with less contrast and more visible grain interference. Hardwoods engrave slower but the result is richer. Painted or stained wood engraves differently than raw wood — the laser burns through the finish first, which can create interesting two-tone effects or messy results depending on the finish.

Acrylic
Acrylic is the material that makes a laser engraved sign look professional.
Best results: Rowmark LaserMax acrylic, cast acrylic in standard thicknesses. The laser engraves the back of a two-color Rowmark piece to reveal the core color — producing sharp, consistent lettering that looks like a real sign. For clear acrylic, the laser frosts the surface — the engraved area becomes matte white against clear, which catches light beautifully.
What it's used for: Business signs, lobby displays, awards, backlit signage, event name tags, plaques. The Art of Graze, a catering business in Estero, ordered custom acrylic signage for their brand — that's a real use case I've filled.
What to know: Extruded acrylic (cheaper) doesn't engrave as cleanly as cast acrylic. For sign applications, Rowmark LaserMax is the industry standard because it's engineered specifically for laser engraving. Clear acrylic looks different depending on whether the piece is lit from behind — plan for your display environment before you choose a thickness.
Glass
Glass engraving is one of the most requested services I do, and one of the most misunderstood.
Best results: Stemless wine glasses, pint glasses, whiskey glasses, decanters. I use a defocus technique on the Thunder Nova 51 — the beam is intentionally unfocused to produce a frosted matte finish rather than sharp lines. This is counterintuitive: the trick isn't more precision, it's less. The result is a consistent frosted appearance that's legible from across a table and permanent through the dishwasher.
What it's used for: Wedding gifts, anniversary sets, bridesmaid gifts, Father's Day presents, corporate hospitality pieces.
What to know: Thin glass (cheap wine glasses from big box stores) can crack under the heat differential of laser engraving. I recommend better-quality glassware — Libbey, Bormioli, or similarly-rated glass — for consistent results without breakage. Very thin glass, crystal, or antique pieces are generally not good candidates.
Leather
Leather engraving is one of my favorite materials to work with because the results look intentional and handmade in the best sense.
Best results: Genuine leather patches, leather keychains, leather coasters, vegetable-tanned leather goods. The laser darkens the surface of genuine leather — darker coloring against the natural tan or brown — and the result has texture and depth you can feel.
What it's used for: Keychains, leather patches on hats or bags, coasters, bookmarks, small corporate gifts. I do bulk leather patch orders for businesses that want a branded item that feels premium without a premium price.
What to know: Faux leather (PU/vinyl) can technically be engraved but the process produces fumes that are harder to exhaust safely and the results are inconsistent. I work with genuine leather exclusively. The thickness and tanning method of the leather affects how much the surface darkens — I test a sample of any new leather stock before running a production order.
Metal and Coated Metals
This is where things get technical.
What works: Anodized aluminum (tumblers, water bottles, certain signage) and powder-coated metals. The laser ablates (removes) the coating or anodization layer to reveal the bare metal beneath — producing a bright silver/metallic contrast against the colored surface. This is how YETI tumbler engraving works: the powder coat is removed by the laser to expose the stainless beneath.
Polar Camel tumblers are my preferred drinkware for engraving because the powder coat layer is consistent and the results are predictably clean. YETI, Stanley, and similar products also engrave well. All engraving on drinkware is done using a rotary attachment that spins the tumbler at a constant rate while the laser passes across it — this is what allows engraving on a curved surface.
What doesn't work (for a CO₂ laser): Bare stainless steel, bare aluminum, and most uncoated metals cannot be marked by a CO₂ laser directly. The beam reflects off bare metal rather than being absorbed. A fiber laser handles bare metal. I use a CO₂ laser, which means bare stainless and aluminum are outside my capability without a specialized marking compound.
What to know when sending customer-supplied items: Drinkware must have a powder coat or anodized finish for the engraving to work. Some cheap tumblers have an inconsistent or thin coating that produces uneven results. I test on a small area first when working with customer-supplied items I haven't seen before.

What I Can't Engrave (And Why)
Bare stainless and uncoated metal: CO₂ lasers don't mark bare metal without a marking compound. It's a laser physics issue, not a skill issue.
Tempered or safety glass: The stress introduced by laser engraving can shatter tempered glass. Drinking glasses for engraving should always be annealed (regular) glass, not tempered.
Polycarbonate (Lexan): Polycarbonate technically engraves but produces an ugly, chipped edge rather than a smooth mark. Not recommended for any visible application.
Food-contact surfaces you'll cut raw meat on: Laser engraving creates a textured surface where bacteria can harbor. I engrave cutting boards primarily for display, gifting, and light kitchen use (bread, vegetables). I always recommend customers use a separate board for raw proteins.
Plastics with chlorine (PVC): These produce toxic chlorine gas when laser engraved. I won't engrave PVC materials under any circumstances.
How to Find Out If Your Item Can Be Engraved
The fastest answer is to text me a photo of the item with a note about what you want engraved. I'll tell you within a few hours whether it's a good candidate, what the result will look like, and what it'll cost.

What can you engrave? Wood (Baltic birch, maple, walnut, bamboo), acrylic (Rowmark LaserMax and cast acrylic), glass (using a defocus technique), genuine leather, and anodized or powder-coated metals including YETI and Polar Camel tumblers. Bare stainless steel, tempered glass, PVC, and polycarbonate are not compatible with CO₂ laser engraving. Veronica Ramirez at Palm Coast Customs in Estero, Florida handles all types — text or DM with a photo to find out if your item works.
