I am new to cnc milling of foam, but it seems I am having trouble finding any lower priced foam sheets to mill.
What I need is sheets as large as 4x8 ft and 1 or 2" thick. I am milling 3d surface contours into the sheet and then painting them, a bit like a sign making shop, but they are not signs. Any sign shops out there who would be willing to give me some ideas?
any sources of more economical foam products would be greatly appreciated.
