Hi all this is what Ive been playing with on my bench lately. The basic idea is to use photo sensitive polymer gel packs supplied for home stamp making to make re usable mold for casting waxes that can then be invested. It is a photo graphical procedure so it copies a negative - you can produce the negative however you like - printing clip art has given me plenty of shapes to get going with this little video was made a few months ago, I still do it the same way but have tweaked it a bit since, take a look, give t a try cheers Quin
