Hello,

I believe I can step in here as I have enough experience with both extruded and cast material.

The extruded was made by pushing the resin out as it cools, while the cast (I hate it when they call it cell cast, make it sounds fancy and no body call them this in the acrylic industry) are made entirely in the mold.

Bottom line, if you are making products commercially and plan to ship them out via UPS, you want something that is inherently strong. Extruded just breaks too easily during shipment and such. Not worthwhile.
