 +Some not Explicitly approved materials, but have been tested to be ok, check with the laser officer before doing more than small samples of these.

 +  * Speedball Speedy-Cut-Easy (the easy is important, non easy has pvc in it), other hackerspaces/laser users have reported using it fine 
 +      * Ingredients COMPOSITION / INFORMATION ON INGREDIENTS \\ Blend of paraphinic plasticizer, calcium carbonate, titanium dioxide, styrene butadiene styrene synthetic \\ rubber, white factis synthetic rubber, polysiloxane, magnesium stearate, calcium stearate. 
 +      * It is a bit stinky. 
 +  * 3M™ Scotchlite™ Reflective tape, still unknown on composition of backing, but the tape itself is acrylic and the reflective stuff does not hurt the cutter, but does need to be masked with tape for good /clean cutting
