You must ventilate the fumes if cutting Depron or FFF with a laser. The fumes are toxic and unpleasant. Most commercial lasers have an outlet in the cabinet for venting.

My thread has links to a lot of various sites for information regarding toxicity of various foams. Second post has links to websites such as CDC, which have various studies and pdfs that include information on how to protect yourself.

While no conclusive studies have been made between foam fumes and cancer, the chemicals have been positively linked to kidney, liver, lung and brain damage.
