I was browsing instructables and came across a reference to "funtodo casting resin" I looked it up on their web site here:
http://www.funtodo.net/our-3d-resin-properties.html
... Apparently it cures at up to 415nm, so it should cure with the peachy's laser (405 nm), and can be used to cast "bronze, copper, tin and iron". I'm not a beta tester, so I can't test it of course, but I was wondering if anyone has heard anything - good or bad about this resin?
