MOSFET problems!

I ordered a MOSFET module on eBay for my 3D printer and I did not get the one in the picture but I got this: If there is any way I could use this on my Anet A8 could someone tell me how, as it only has one input connector, DC in, and 12 V out.

Can I print in wax?

I'd like to start 3d printing in wax. Is there a reasonably priced 3d printer that is capable of it? Am I right in assuming that all I need is to make my own filament and set extruder temperature correctly, or do I miss something?
