LOWER YOUR CARBON FOOTPRINT TREMENDOUSLY??
You are delusional, I have ordered more deliveries from overseas using dirty filthy production and delivery methods since buying my printer also delivered via dirty filthy means.
I need all sorts of filaments, print bed heaters from China, alternate nozzles, LED lighting, replacement thermistors, the list goes on and on.
These printers are hobby and experimental devices only for the vast majority of us. Those that treat their printers more professionally are sending their printed items out via?, you guessed it.
3D Printing is not even close to beginning a whisper of a sniff of a rumour of a dent in international manufacturing and distribution.
Drop the self-serving eco babble, dismount your incredibly high horse and re-enter the real world.

You're not being heckled by trolls. Trolls throw out controversial statements to purposely wind people up and start arguments, mirror much?
