Here is a bit of an update for Atlanta acrylic sourcing:
Piedmont Plastics is very friendly, they have one long front desk to talk to sales reps at. Although they are a very large supplier of acrylics (think of the businesses that make signs for Home Depot, etc.), they also have lots of large scrap. I spoke with Ryan, who hooked me up with a colored mirror sample pack, a clear/patterned/black sample pack, and then off-cuts from the warehouse. He said that their scraps go to the recyclers, and I was welcome to come in anytime to select material out of their recycle bins. The warehouse requires close-toed shoes, like any warehouse. Like seriously, this guy hooked me up with about 100 lbs of offcuts of silver mirror acrylic, the equivalents of 18 or so glowforge-sized acrylic sheets in clear, red, green, blue, and home depot orange ;p ;p ;p
Ryan suggested checking out N.Glantz and Calsak Plastics, but we couldn’t get to them before they closed that day.
.
Johnson Plastics Plus though, meh. Their front office is basically order pickup, they have some products to look at, but nothing that you can buy there unless you are picking up an order that you put in online. They will happily give you a catalog though.
Atlanta Plastics, either no longer at the Google Maps address, or not a storefront.
Don’t forget the Restore, we picked up 2-3 sheets of grey marble coaster-sized hex tiles for about $3.
