For your intended purpose of casting, no. But why not broaden its market by getting certified at some point and then branching out into the culinary market. AFAIK, the only thing available in that market is the ChefJet which has yet to ship. Since you are working with low temperature source material, chocolate, butter, even stuff like fondant could be in your grasp.

And I was wondering if anyone had considered stuff like caramelized sugar and isomalt. Isomalt melts at 150c ish. Right in the range of many extruders. Can you say 3D printed candy?

I was also wondering if anyone had considered a cooling bed instead of a heating bed, perhaps using peltier chips? Might enhance deposition of cool melting products like wax, chocolate etc by more rapidly solidifying it before it can sag/ooze. Not thinking actually frosting a beer mug cold but more along the lines of sinking heat away from the deposited material and taking it down to room temp or slightly below before it can distort after being deposited. Just a thought. Dunno if it would help or hurt.
