3D printing is not unlike the normal old-fashioned 2D printing process, according to Jones. Say someone wants to print business cards. She'll come in with a rough idea of what she's looking for. One of the staff members will begin asking questions: What color did you have in mind? What kind of paper do you like? How do you feel about this font? Then you'll print out a first-go, and it'll be close but not perfect, and you'll improve it from there.
