Thread: Cheap Sign Foam Alternative
-
17-08-2011 #1
Looking for help in finding material for 3D carving,
Sign foam seems to be what am looking for but too expensive just to have a play.
found high density urethane materials in the US a fair prices but no luck in the UK
If any one can point me to any alternative materials to try would be of great help
Also a Hard finish coating would be a plus
thanks in advance for any input

I was going to suggest that. Two part polyurethane foam is good as you can just make a box the right size, work out the mass to mix to get the right density and fill it up. You do have to be quick, otherwise this happens:
You can get it in decent quantities here:

I keep meaning to get some myself for prototyping.

its basically the same stuff just already in a shhet with foil glue on that you can just pull off. the shhets come in up to 6" thick nd you can glue them together and cut with wood saw

I use these Panel Systems in Sheffield, I buy the precut foam in the attached link. It's not the cheapest way to buy foam but it's handy as it comes in a 2ft x 2ft x 1ft box that protects the foam. It's easy to store and will keep me going for years.
They may have denser foam in 2ft x 8ft sheets, but this grade suits me.
