Apoxie Sculpt vs. Polymorph review I'm using Apoxie Sculpt for making my prototypes for a long time already, and I'veheard about this new (maybe not so new but I'm pretty slowpoke) stuff called Polymorph/Polycaprolactone/PCL. So I purchased this stuff to try it. I won't be telling much about Apoxie Sculpt as it's been reviewed numerous times. It's a 2-part epoxy putty, very strong and suitable for sculpting. You mix two equal pieces of each component, sculpt for 1-3 hours and then leave it to polymerize for 24 hrs (I recommend 48 hrs). Then you sand it, drill it, carve it and do whatever you want with it. The biggest advantage and the biggest flaw of the Polymorph is the same thing))) It melts at 65 degrees by Celsium. This trait makes the sculpting process much much faster but you have to preserve the result from too much heat. I decided to compare the prices for the both mediums. Like, last time I purchased two 4 lbs packs of Apoxie for $139 including shipping from USA to Ukraine (the shipping took about a half of total cost). I had to make a mini GO because I needed only 1 pack of 2 lbs/1900 g. So the price per 1 kg is $36,58 for me. And I purchased 350 g of Polymorph on Ebay for $12.88, so the price per 1 kg is $36.80. Pretty equal. After Polymorph hardens you can cut and drill it, but it's a bit harder to do than on Apoxie Sculpt, as Polymorph is rather flexible. It reminds me of a hot glue sticks, but it's significantly sturdier. It's slightly transparent too. The stuff is great for making molds, as it fills in the pores and takes the surface copy. Or it can be molded by pouring into the molds while liquid. I even managed to press slightly cooled but still soft Polymorph to Castilene to copy the surface - and you know that Castilene turns liquid at 70 degrees by Celsium, i.e. it has almost the same melting temp! Polymorph managed to take the surface details nicely without ruining the Castilene piece. It's hard to sand and to cut off a thin pieces due to a flexible structure of Polymorph. Cutting the large pieces is not a problem. If sanded gently with a high grit sandpaper (like 800-1000) it turns matte, I like its surface. I wonder if it's good enough for making BJD prototypes, or is the stuff too flexible? Anybody tried it?
