incorporating coffee grounds into the substrate for mushroom growth has been a common practice in the mushroom cultivation community for small-scale production

I can finally call it "research!"

new materials often demand new hardware systems. [...] we developed a custom extrusion printhead [...] extrusion printhead is easy to assemble, inexpensive yet functional, compatible with existing slicing software, and can be integrated into mainstream 3D printer control boards

🤯 This is what most papers on these miss. These materials have the potential to have a huge impact on small scale, local community solutions, but only if it's done like this! Incredible work.

Ok, now they're just flirting with me
