Via Medium, an exploration of the maker movement and what its future might be.
"There seems to be a misconception about what 3D printing does and does not enable. Does it allow us to delight a four-year-old by pulling a mini Darth Vader toy seemingly out of thin air? It does. But the object doesn’t materialize from nothing. A 3D printer consumes about 50 to 100 times more electrical energy than injection molding to make an item of the same weight. On top of that, the emissions from desktop 3D printers are similar to burning a cigarette or cooking on a gas or electric stove. And the material of choice for all this new stuff we’re clamoring to make is overwhelmingly plastic. In a sense, it’s a reverse environmental offset, counteracting recent legislation to reduce plastic use through grocery bag bans and packaging redesigns. While more people tote reuasable cloth bags to the supermarket, plastic is piling up in other domains, from TechShop to Target."
