Laser cutting a spring - choice of material?
Acrylic it too brittle for my needs, but I know that some plastics can, when cut with a laser, give off fumes and gases that will damage the laser cutter (eg PVC gives off gases that will cloud the mirrors).
What materials would you recommend?
(I've attached a quick sketch of the general shape of the planned spring.)
EDIT: I've added a rough sketch of the project - a torch, cut from acrylic. The four projections are to bind it together with an elastic band. The switch operates like a syringe.
