I'm interested in creating some basic shapes out of acrylic but don't
want to cut acrylic sheets or order custom cuts from manufacturers.
My shape is basically 0.75" thick x 2.50" long x 3.00" wide.
I need to create alot of these quickly and inexpensively.
Are there at home acrylic polymer kits I could use or could I create my
own mold and buy off the shelf acrylic to create these?
I am a newcomer to plastics and don't know where I could buy acrylic
liquid and what I should buy, etc.
I don't know of a pourable acrylic. They do have clear plastic
molding stuff at hobby stores; I think it's polyester. Not too
expensive, but it shrinks quite a bit when it cures.

http://www.eagerplastics.com/4101.htm I haven't used this stuff, but
I've used other stuff that is probably similar.
Clear urethane is better, but it's pricey. I've had good luck with
Polytek products.

Their catalog is a good primer on making cast plastic objects.
