    The dried grounds were sifted with a standard kitchen strainer to remove large clumps and then mixed with xanthan gum and carboxymethyl cellulose powders, which serve a similar purpose to binders, stabilizers, and thickeners.

    Yeah, so don’t throw out those used coffee grounds, just mix them with the carboxymethyl cellulose powder you probably have in the cupboard, and the leftover xantham gum you have laying around.

    Then make a custom syringe feeder for your 3d printer.

      Both of those ingredients are cheap, and Xantham Gum in particular is used in gluten free baking recipes a lot.

            this is not one of them. Xanthan gum is a food additive created by a sugar that’s fermented by a bacteria. It’s a soluble fiber and commonly used to thicken or stabilize foods.

              I don’t doubt it, I just have a problem with the reasoning that something is “natural” and therefore good. It’s a common misconception that charlatans use to prey on people.
