Short answer
No. Acrylic is one of the more commonly approved materials, but acrylic is not one uniform material, and approval is by exact product on your machine. Another school’s approved list is not approval for yours. This applies to enclosed machines at Class 1 or Class 2 in the configuration you run.
Three schools, three answers, so the word acrylic is not the approval. These are other schools’ lists, not approval for yours; enclosed Class 1 or Class 2 machines only.
Programs differ. One university maker hub approves cast acrylic only, another allows acrylic under a quarter inch, and the University of Florida accepts most acrylics but warns that certain ones, particularly rubbery ones, release hydrogen cyanide and tells users to read the SDS. Polycarbonate is not acrylic: Emory prohibits it, and MIT notes it cuts poorly and generates soot.
Treat acrylic as a material that can flame, and stay with the machine the whole job. Any flame means stop with the emergency stop or the switch you were trained to use; do not open the lid to look, move students away, then follow your school’s written fire procedure. Emissions matter too: in one study of CO2 laser cutting of acrylic sheet, the fume extractor captured gases well but not particulates such as microplastics, which were released when the lid was opened after cutting. After the job, keep the lid closed and the exhaust running for the interval in your manual or your program’s written figure.
Use only documented acrylic your machine maker and program allow. If you cannot confirm that a clear sheet is acrylic, do not cut it. Open-frame, open-bed, pass-through, converted, or Class 3B or Class 4 machines are outside this answer and need a laser safety officer and written program first.
