Don’t throw out those used coffee grounds—use them for 3D printing instead
Any object you create can be thrown back into a coffee grinder and reused on a new object.
You're viewing a single thread.
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.
And your things still look like they were printed with solidified shit.
Both of those ingredients are cheap, and Xantham Gum in particular is used in gluten free baking recipes a lot.
its a thickener in sauces too, very handy and all natural despite the scary name
It being natural doesn't mean anything, though. Plenty of naturally dangerous things out there...
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.
