Okay I am planning on getting a paste extruder. I was wonder if marshmallow or dough are in the realm of possibility.
what about Marshmallows? Marshmallows require to sit for 4 hours so 3D printing seems like a good idea.
Cement paste or mortar with very fine aggregates
We have tried color changing drywall compound, printed pretty nicely. I believe there is a video on our yt channel.
Problem was the final product was very brittle, as expected. Likely due to weak binder to hold the particles together.
