Don’t throw out those used coffee grounds–use them for 3D printing instead

How recyclable are "xanthan gum and carboxymethyl cellulose powders"?

Carboxymethl cellulose can be made from wood pulp and acetic acid (vinegar). Xantham gum is usually made from fermented sugar.

Both seem pretty biodegradable to me actually, which is surprising.

They're biodegradable food additives.

Anyone know what printer they’re using?

It looks like a modified ender 3 or ender 3 clone

Based on what can be seen behind him at 0:46 (DWIN screen) it is a significantly modified Ender 3V2 or Ender 3 S1/S1 Pro. Based the design of the gantry, I think it is the Ender 3V2.

I use our used coffee grounds to "3D print" plants via the compost pile in our garden.

I figured an over abundance of coffee grounds would be pretty acidic in compost but your post made me curious. Apparently (anecdotally through you and “scientifically” via Google) this is a myth and coffee grounds are fine in compost.

What surprise me is that they don't have to reheat the liquid/preparation to be used in the extruder and still they say that the resulting object is very strong.

Given that composting isn't really a thing in our city...this is compelling.

Perhaps it is the best excuse to get into 3d printing? ;)

We need a keurig filament stat!
