You don’t have to spend a fortune to get started with 3D printing. Take OLO for instance. It is a smartphone powered 3D printer that works with iOS and Android devices and uses light from your phone’s display to print 3D objects. You can 3D print your own design or other people’s work.
OLO is pretty easy to use. Just select your design, pour in resin, and you are ready to go. The printer has a X/Y resolution of up to 0.042mm. It is easy to use and clean. You can find out more about it here.
