Delrin vs acrylic for laser cutting in one paragraph

Acrylic is the laser-friendly plastic in these listings: the Adrattnay mirror sheets state CO2 laser compatibility with no violent odor, the YMYKLB cast sheets state clean cuts with no burning or yellowing on CO2 lasers, and the Suzile cast sheets state laser cutting with no burrs or marks. Delrin has no listing here, so nothing below is scored against it; the delrin side is described only in general terms.

Why the listings are all acrylic

Every listing here is an acrylic sheet product: clear plexiglass, mirror acrylic, colored cast acrylic in 12 colors, and colored cast acrylic in 30 colors. Thicknesses run from 1/8 inch to 1/4 inch, and pack sizes from 8 to 30 sheets. The listings emphasize protective film, consistent thickness and clean laser edges. No listing names delrin, an acetal plastic, so the listings offer no delrin grades, thicknesses or cutting claims to compare.

The four acrylic sheets in this guide

Ranked by what each listing states for laser work. The YMYKLB 12-pack leads: 12 by 12 inch colored cast acrylic at 1/8 inch, stated for CO2 lasers with clean cuts, no burning or yellowing, UV resistance and 0 percent light transmittance on the colors. Next is the Adrattnay 8-pack: 8 by 8 inch mirror acrylic in 8 colors at 1/8 inch, stated CO2 laser-compatible with no violent odor during cutting, protective film left on during the cut. Third is the Suzile 30-pack: 3.9 by 3.9 inch colored cast acrylic in 30 colors at 1/8 inch, stated for laser cutting with no burrs and no marks. The KERTLOU 10-pack closes the list: 8 by 10 inch clear plexiglass at 1/4 inch, which states no laser cut and directs you to saw or CNC instead.

Which sheet fits which project

Match the sheet to the work using only what the listings state:

• Reflective crafts and signage: the Adrattnay mirror sheets list crafts, mirrors, windows, signs, display stands, cake toppers, model building, home decor, holiday decor, photo frames, stand-up signs and desktop protectors. The listing describes 1/8 inch single-sided mirror acrylic, one sheet of each of the 8 colors, for indoor and outdoor use. Keep the film on during the cut and peel it after.
• Larger flat work and outdoor signs: the YMYKLB 12 by 12 inch cast sheets are the largest single sheet here. Listed uses include pet ID tags, cake mats, display stands, signage, home decor, holiday ornaments, wedding invitations and personalized gifts. The listing states 0 percent light transmittance on the colors, weatherproof and UV resistant, so the bright colors hold up in outdoor use.
• Small colorful parts: the Suzile 30-pack at 3.9 by 3.9 inch in 30 colors suits earrings, necklaces, bracelets, keychains, Christmas ornaments and other small decor, all listed uses. The listing states smooth edges with no burrs and no marks on the laser cutter.
• Clear panels for saw and CNC: the KERTLOU 1/4 inch clear sheets state no laser cut; the listing names engraver, power saw, jigsaw, drill, bandsaw, CNC engraver and hand tools. Listed uses include photo and poster frames, artwork display, wedding welcome boards, table tops, protective barriers, shelves and holders.

Listing details that need a second look

Two listings contradict themselves between the title and the spec table. Our method trusts the title and bullets over the spec table:

• The YMYKLB title and bullets say a 12-pack of 12 by 12 inch sheets at 1/8 inch (3 mm); the spec table says 15 packs and 0.12 inch. Use the 12-pack figure from the title.
• The Adrattnay title and bullets say 8 mirror sheets at 8 by 8 by 1/8 inch; the spec table says 10 items and 0.13 inch. Use the 8-sheet figure from the title and bullets, and note the listing says edge lengths may vary by 2 mm.
• The KERTLOU title itself carries the warning No Laser Cut and repeats it in the bullets: do not use laser engraving. That is the listing speaking, not an omission: treat this sheet as saw and CNC stock only.

The one that says no laser

The KERTLOU listing is explicit: cut with engraver, power saw or hand tools, no laser cut, and do not use laser engraving. It is the thickest sheet here at 1/4 inch and the only clear plexiglass. If the job is laser cutting, buy one of the other three; the KERTLOU is for saw and CNC work.

Laser safety basics for these sheets

Cutting acrylic on a laser needs two things handled before the job starts:

• Ventilation: move the fumes out of the room. Exhaust outdoors or use a filter made for laser fumes; see our fume extractor guide.
• Fire: keep a suitable extinguisher within reach and stay with the machine while it runs.
• Materials to skip: never laser PVC, vinyl, PVC-based faux leather, polycarbonate or ABS.
• Eyewear: the Adrattnay and YMYKLB listings name CO2 lasers; use eyewear only if its listing states an optical density and a wavelength range that matches your machine.

FAQ: lasers and CNC

Can I laser cut delrin?

No listing here covers delrin, so there is no listing-backed answer. The three laser-compatible listings here are all acrylic.

Which acrylic is best for CO2 lasers?

The YMYKLB and Adrattnay both state CO2 laser compatibility directly; the Suzile states laser cutting generally. The KERTLOU states no laser cut.

Cast or extruded acrylic?

The YMYKLB and Suzile state cast acrylic. The KERTLOU and Adrattnay do not state the manufacturing type.

Which packs have the most colors?

The Suzile at 30 colors, followed by the YMYKLB at 12 and the Adrattnay at 8. The KERTLOU is clear only.

Do the sheets come protected?

All four state protective film or paper on the faces; the Adrattnay states the film stays on during laser cutting and comes off after.

Can I cut the KERTLOU clear sheets on a table saw?

Yes: the listing states cutting with an engraver, power saw, jigsaw, drill, bandsaw, CNC engraver and hand tools, and separately states no laser cut and no laser engraving.
