Acrylic vs aluminum for laser engraving: what the listings state
The OMTech listing sells a 10-pack of clear acrylic sheets, 12 by 8 in and 3 mm thick, for laser engraving and DIY projects like displays and signs. The PATIKIL listing sells a 10-pack of black anodized aluminum sheets, 7 by 5 by 1/32 in, as engraving blanks for signs, badges, plaques and trophies. The weparmeety listing sells anodized aluminum business card blanks, 86 by 54 mm, for laser engraving cards and tags. For clear versus mirrored stock, see mirror vs clear acrylic for laser engraving.
Engraving and cutting
All three listings name laser engraving as the intended process. OMTech says each sheet can be cut and shaped with hand or power tools including laser engravers, which matters if you cut display shapes rather than only engraving the surface. PATIKIL describes engraving the anodized sheets into signs, badges, plaques and plates, and notes an anti-scratch layer on the front to remove before use. The weparmeety cards are described as suitable for laser engraving, with rounded corners and a smooth surface. Compare thin stock options in best thin aluminum sheet.
Sizes, thickness and pack counts
The OMTech acrylic sheets are 12 by 8 in and 3 mm thick, ten to a pack. The PATIKIL aluminum sheets are 7 by 5 in and 0.8 mm thick, stated as 1/32 in in the title and bullets, ten to a pack; the spec table lists the thickness as 0.04 in, so trust the title figure. The weparmeety title states 180 cards at 86 by 54 mm and 0.21 mm thick in 9 colors, but its spec table says 100 pcs, 0.45 mm and 10 colors; trust the title and bullets here as well.
Weight and handling
The PATIKIL pack lists an item weight of 1.15 lb for its ten sheets. The weparmeety listing gives 15.8 ounces for the card pack. The OMTech listing states no weight, so there is no stated basis for comparing the acrylic pack against the aluminum ones. The PATIKIL bullets claim scratch resistance and the OMTech bullets claim resistance to warping and cracking; treat both as the maker’s claims.

Cutting acrylic makes smoke and fine dust: ventilate the work area and stay with the machine while it runs. The PATIKIL listing advises personal protective measures during engraving. Never laser PVC or vinyl.
