Mirror vs clear: the material difference

Mirror acrylic is acrylic sheet with a reflective coating on one face. The listings here are gold mirror, which reads as a warm metallic gold. Engraving removes the mirror coating to reveal frosted acrylic beneath, giving a high-contrast mark. The back is typically gray coated, per the Adrattnay listing. Cut mirror acrylic with the mirror face up and leave the protective film on during cutting, per the listings.

Clear acrylic is transparent with glass-like clarity. Engraving turns it frosted white, which reads well against the clear background. It suits LED-lit signs, display cases and layered projects. The KAITELA listing states the sheet is cast acrylic with no yellowing over time; the Senbota listing describes optical-grade PMMA for LED light bases.

For cutting, both types work on CO2 lasers. The Adrattnay listing states CO2 compatibility explicitly with no violent odor during cutting. Cast acrylic (KAITELA, Senbota) cuts with cleaner edges than extruded. Thickness here runs 3mm to 4mm, a comfortable range for desktop CO2 machines.

Acrylic gear: four picks

The four listings below are ranked by the listing details. Every figure comes from the listing.

1. Adrattnay 3-pack, 8×8 inch gold mirror

Three gold mirror acrylic sheets at 8 x 8 x 1/8 inch (20.2cm x 20.2cm x 3mm), with edge lengths varying by 2mm per the listing. Single-sided mirror with a plastic protective film on the front and gray coating on the back. The listing states CO2 laser compatibility with smooth cut surfaces and edges, and lists uses from cake toppers to desktop signs. Leave the film on during laser cutting; remove after the work is done.

2. KINLINK 2-pack, 8×12 inch gold mirror

Two gold mirror cast acrylic sheets at 8 x 12 x 0.13 inches (3mm). The listing states 0% light transmittance for the mirror face, meaning full reflectivity, and a protective paper on the surface against scratches and fingerprints. It lists wedding table numbers, invitations and wall art among the uses. Peel the protective paper before use.

3. KAITELA 10-pack, 4×6 inch clear cast

Ten clear cast acrylic sheets at 4 x 6 inches and 1/8 inch thick (0.118 inch / 3mm nominal). The listing states glass-like clarity, UV resistance and no yellowing with long-term use, with laser-cut clean edges and no chips. It lists signs, display cases, picture frames and epoxy molds among the uses. Remove the protective film on both sides before use.

4. Senbota 12-pack, 5.9×5.1 inch clear for LED bases

Twelve clear cast acrylic sheets at 5.9 x 5.1 inches and 4mm (0.16 inch) thick, sized for LED light base slots about 2.6 inches wide and 0.5 inch deep per the listing. The listing describes optical-grade PMMA with high clarity and laser-cut burr-free edges. Each sheet weighs 65 g per the spec table.

Choosing between mirror and clear

Pick mirror acrylic for signs, cake toppers and decor where a reflective face adds impact. Pick clear for LED-lit projects, display cases and layered designs where transparency matters. For a first acrylic project, clear cast is the forgiving choice: the engraved mark is easy to read and the material is widely available.

Size-wise, the listings here offer 8×12, 8×8, 4×6 and 5.9×5.1 inch sheets. Match the sheet to your machine bed and the project size; smaller sheets waste less on trial cuts.

Safety

Laser cutting acrylic makes fumes; ventilate well and never leave the machine unattended. Keep a fire extinguisher nearby. Cast acrylic is the safer choice for clean cuts. See the FDA guidance on laser products.

FAQ: lasers and CNC

Can a diode laser cut 3mm acrylic?

The listings here specify CO2 laser compatibility. Diode lasers struggle with clear acrylic; check your machine’s rated materials before buying.

Which side of mirror acrylic do I engrave?

Per the listings, engrave the mirror face with the protective film left on during cutting, then remove the film after the work is done.

What is the difference between cast and extruded acrylic?

The listings here are cast acrylic, which the KAITELA listing states cuts with clean edges and no chips. Cast engraves to a frosted finish; extruded can melt unevenly.

What thickness suits a desktop CO2 laser?

The listings here run 3mm to 4mm, which desktop CO2 machines handle comfortably. Thicker stock needs more power or multiple passes.
