2mm vs 3mm acrylic for laser cutting: the short answer

Choose the thinner sheet for light work: small signs, ornaments, tags, and layered pieces where weight and easy cutting matter. Choose the thicker sheet for pieces that need to stand up on their own: display stands, plaques, and decor that gets handled often. Material type matters as much as thickness. The SimbaLux and Maitrova listings are cast acrylic, while the Remerry listing states plainly that its product is not cast acrylic. Color is the other split: SimbaLux is clear, Remerry offers 12 colors, MAPRIAL offers glitter colors, and Maitrova offers a 7 pack of colored cast sheets.

How thickness changes the cut

On the thinner side, SimbaLux describes its cell cast sheet as cutting cleanly with a laser, tablesaw, jigsaw, drill, router, or bandsaw, with clean cut edges without burrs and sharper laser engraving. Remerry says its colored sheets can be easily cut by lasers, table saws, and drills, and notes high rigidity with a smooth, translucent surface. On the thicker side, Maitrova says its cast sheets deliver clean, crisp cuts without burning, yellowing, burrs, or warping, and lists CO2, Glowforge, and xTool lasers among the tools that work smoothly with them. MAPRIAL notes that a CO2 laser engraver gives a better cutting result with its sheets, and that there is no violent odor during cutting. None of these listings state a machine power figure, so match the sheet to a machine you already know rather than guessing from thickness alone.

The gear: sheets to compare

The four sheet sets below are ranked from the strongest overall listing to the weakest, based on stated material, cutting notes, and consistency of the listing.

Maitrova colored cast sheets, 7 pack

Maitrova lists a 7 pack of 8×8 inch, 1/8 inch (3mm) thick colored cast acrylic sheets with double-sided protective film. The maker says the sheets work smoothly with CO2, Glowforge, and xTool lasers, engraving machines, table saws, and hand tools, delivering clean, crisp cuts without burning, yellowing, burrs, or warping. The sheets are described as lightweight, impact-resistant, recyclable, waterproof, and weather-resistant, with color stability without cracking, fading, yellowing, or fogging. This is the most complete thicker-sheet listing here: cast material, named laser types, and a clear cutting result.

SimbaLux clear cast sheets, 5 pack

SimbaLux lists a 5 pack of clear cast plexiglass sheets sized 8 inches by 10 inches, 0.08 inches thick, described as 2mm nominal with a stated range of 1.7mm to 2.3mm. The maker describes a high-clarity Grade A clear finish with improved weather and UV resistance for the sheet itself, and a cell cast design that offers clean cut edges without burrs, sharper laser engraving, and higher resistance to scratch and chemical solvents. The listing also states an item weight of 0.68 kg. For clear work such as frame glass replacement, art protectors, and laser engraved signage, this is the clearest thinner-sheet option here.

MAPRIAL glitter sheets, 10 pack

MAPRIAL lists a 10 pack of glitter acrylic sheets with tweezers for removing the protective coating, in 10 colors. The listing states two sizes that do not agree: the title says 8 x 8 x 1/8 inch, while the bullets say 12x12x1/8 in, 30.2cm x 30.2cm x 2.7-3mm thick, with a tolerance of 0.1-0.3mm. The spec table lists an item thickness of 0.13 inches, which also differs from the title’s 1/8 inch. The sheets have a paper-backed protective coating on both sides, and the listing says not to tear off the paper when laser engraving or cutting, but to tear it off after finishing the work. The surface is described as smooth and UV-resistant, and a CO2 laser engraver is noted as giving a better cutting result. Check the listing size before ordering, since the title and bullets differ.

Remerry colored sheets, 24 pack

Remerry lists 24 pieces of colored acrylic sheets in 12 opaque colors, with paper covering. The listing states two sizes that do not agree: the title says 16 x 12 inch, while the bullets say approximately 30 x 30 cm, 12 x 12 inches, and 0.2 cm, 0.08 inch in thickness. The spec table lists an item thickness of 2 millimeters. The maker states the sheets have high rigidity and proper thickness, can be easily cut by lasers, table saws, and drills, and have a smooth, translucent surface. The listing states plainly that this product is not cast acrylic, and says to tear off the protective film on the surface before use to get the colorful appearance. This is the largest pack here and the widest color choice, but the size disagreement and the non-cast material put it last.

Cutting and safety notes

Cutting acrylic needs the same basic care as any laser job:

• Ventilation: exhaust outdoors or use a filter designed for laser fumes. See our fume extractor guide.
• Fire safety: keep a suitable extinguisher within reach and never leave a running job unattended.
• Eye protection: use eyewear only if its listing states an optical density and a wavelength range that matches your laser. None of these sheet listings state eyewear ratings.
• Materials: never laser PVC, vinyl, PVC-based faux leather, polycarbonate or ABS. They can release harmful fumes and damage the machine.

Film handling differs by listing, so follow the sheet you buy: Remerry says to tear off the protective film before use, while MAPRIAL says to keep the paper on during cutting and remove it after finishing. For machine choice, our best laser engraver for small business guide and best laser engraver for wood guide cover the machine side of the same projects.

FAQ: lasers and CNC

Which thickness should I pick for small signs?

For small, light signs, the thinner 2mm sheets suit the job: SimbaLux lists clean cut edges without burrs and sharper engraving on its 2mm nominal cast sheet. For signs that must stand up or be handled often, the thicker 3mm cast sheets from Maitrova give a sturdier piece.

Is cast acrylic better for laser cutting?

The cast listings claim clean results: SimbaLux says its cell cast sheet offers clean cut edges without burrs and sharper engraving, and Maitrova says its cast sheets deliver clean, crisp cuts without burning, yellowing, burrs, or warping. Remerry states plainly that its product is not cast acrylic.

Do I remove the protective film before cutting?

It depends on the listing. Remerry says to tear off the protective film before use to get the colorful appearance. MAPRIAL says not to tear off the paper when laser engraving or cutting, and to tear it off after finishing the work. Maitrova sheets arrive with double-sided protective film to prevent scratches during shipping.

Can I cut acrylic with any laser?

No single listing names every laser type. The listings name several options: SimbaLux lists laser, tablesaw, jigsaw, drill, router, and bandsaw cutting; Maitrova lists CO2, Glowforge, and xTool lasers; MAPRIAL notes that a CO2 laser engraver gives a better cutting result. Match the sheet to the machine types its listing names.

What sizes do these acrylic sheets come in?

SimbaLux lists 8 inches by 10 inches, Maitrova lists 8×8 inch, and MAPRIAL and Remerry list sizes that disagree inside their own listings: MAPRIAL states 8 x 8 x 1/8 inch in the title and 12x12x1/8 in in the bullets, while Remerry states 16 x 12 inch in the title and approximately 12 x 12 inches in the bullets. Confirm the size in the listing before ordering.
