3D printers can be eco friendly and they can be energy efficient. Like most technology developments the early prototypes are energy and environmentally disastrous and then science and people get to work to create better , more efficient models. We don’t need more plastic which cannot be broken down or is toxic. We don’t need devices which burn up energy. We do not need devices which add small particles to the air we breathe. Since 2013 a lot of work has gone into 3D printers and their energy and environmental impact. If you want to look at the issues 3D printers can cause with the environment you can look at this post on LIVESCIENCE but the world has since been tackling some of these issues. 3D printers could save overall energy and environmental impact by printing locally and in smaller numbers to match need. There is a 3D printing pen which recycles plastic bottles. Quora has been discussing the environmental impact of 3D printing but it comes down to us as consumers to know what we are looking for. If you want to know the materials used in 3D printing they are explained here on 3DPrinterHelp. As with anything else we buy we need to look for the environmentally friendly, energy efficient models. We cannot do that unless we know what we are talking about.
