3D printing opens the doors to a post-scarcity society  Industrial 3D printing allows for a cheaper, faster and more sustainable form of production, but somebody still has to sell and purchase the products. Household 3D printers give people the possibility of producing otherwise inaccessible things for a minimal cost, up to hundreds of times cheaper than their current store price20. Numerous websites, such as Thingiverse21, already act as databases for free printable designs. This trend would allow people to save thousands on necessities: food, appliances, medicine, and human organs are some examples. Even systems for power production or more efficient ways of collecting sustainable energy could be created. This would make scarcity disappear as we know it, and thus tackle one of society’s greatest problems. This is a very long way off even with 3D printers but if it is to occur it is essential that the means of production not be monopolised by companies.
