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

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

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&#x27;t really a thing in our city...this is compelling.<p>Perhaps it is the best excuse to get into 3d printing? ;)

How recyclable are &quot;xanthan gum and carboxymethyl cellulose powders&quot;?

Anyone know what printer they’re using?

We need a keurig filament stat!
