Do you have access to a 3D Printer at home? Yes? Awesome - the future is rad! No? No worries, there are definitely other options. Many 3D Printing services exist that allow you to upload a design and receive a 3D print in the mail on a fast turnaround. Shapeways has been around for quite a long time and is reliable though many other companies have followed this model as well.
Inclined to go your own way and build a printer from scratch? The original Prusa 3D Printer is entirely open source hardware and software and there are tons of great plans and adaptations out in the world.
