Re: [CAD_CAM_EDM_DRO] plastics

I work with Corian for a living (as many of you know it's Acrylic). We were
told by the wizards at DuPont that you should indeed use cast, not extruded
acrylics because of internal stress. I don't think you can completely purge
the stress, but heating it to the relaxing point will help relieve it. I
would suggest a test piece at about 180 - 200 degrees F. Be sure to heat
slowly and watch for signs of overheating like blistering and whitening.

Hope this helps,
Jeff
