The difference is minimal between only companies having 3D printers and extending them to households. Printer owners would, for example, still have to purchase and transport printing materials. Many printers still involve large levels of waste19, and these are probably the lower quality printers that individual consumers are more likely to afford. Furthermore, household printing can actually harm the environment by provoking people to consume more than they would if price and convenience were deterrents. Industrial printing on its own can make a significant difference in terms of eco-friendly production: this should not be compromised by dropping all limits on production.
