from the amazon description. My emphasis…
"MoldLay is your 3D Printing solution to making molds. MoldLay
is a wax-like filament that is structurally strong and has almost
no warping at all. It is perfect for the mold making process! It
will keep its shape when surrounded by concrete, but will run out
of the now concrete negative when placed in an oven, leaving
almost no residue behind. *If there is a little residue, it is
easily cleaned out using a simple citric acid solution.*"
I suspect you may need a little more detail on the intended method.
because I suspect the target here is melting it in a conventional
cooking oven as opposed to burning it out in a furnace…
mind you, most plastics, unfilled, should burn out cleanly.
I’m off to look at the composition/MSDS if I can find it…
