Maker's Muse did a flameout test with various materials. Nothing scientific but fun to watch. He was focused on self-extinguishing.<br>
I'll see if I can find the investment casting video again.<br>

Oh, and I've seen chocolate printers! <img src="images/smilies/smile.png" border="0" alt="" title="Smile" smilieid="1" class="inlineimg">
Thanks for the information! I read about PLA last night and it said to be quite strong smelling when burnt and have toxins "dangerous for kids". That video was amazing and it seems like a great way to manufacture a larger scale of products. I'm working directly with ceramics though so I'm looking for a solution where it can be free handed but held up by an inner structure. Think more artsy objects rather than dinnerware etc.

It's very common that we use splints, wood, paper as support structures that later will just burn out. I found this great website yesterday listing different materials. Have you heard of HIPS filament? And my mind was blown away when i find this wood filament too.

I haven't invested in a 3D printer but I was thinking about getting something cheap and simple like the Creality3D. Would the spools work on that machine you think?
