I don't know in other countries, but here in Indonesia the use of 3d printers is still rare and only for specific purpose (not something that you can easily find around you in your daily life). IMO, the user-friendliness and its price are what most people here consider as disadvantages for 3d printers. Maybe due to the name is still "printer" then some people think it shouldn't be much different than conventional printers that print on paper
