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.

For those who come in with an idea for a 3D object, they'll come in and work with Jones and an engineer he's hired, Tei Newman-Lehman, and, "between the three of us, we get your idea on the paper." (Newman-Lehman, Jones says, used to design airplane parts for the military, but, "with sequestration and stuff, he's now doing this. But he's got a degree in nuclear engineering. I mean, that's a little overkill, but he's happy.") And then from paper to software to printer, the object transitions from idea to a physical fact.

"I've been in the printing business for a good solid 15 years, and it's a similar process initially, it's just that when we hit the print button, it does a different thing."

"That's the part that I get to enjoy -- to watch people go through the process of the birth of their idea," Jones says, "You should see their faces! When they see their part, it's like, it's amazing. It's not like they're an engineer. We've had many engineers come in and many doctors come in. And they come in with files that are perfect and they print perfectly and they get exactly what they expect. But other people, come in and they're like, in a couple of days or a week, they're holding their part, and it's a magical moment."

It's this process, from idea to object, that excites Jones. "It is astounding to me, as a 51-year-old, that I can literally take my idea, if I was willing to put in the hours today, I could take an idea out of my head, or out of somebody's head, and by the end of the day I could have a hard plastic prototype in their hand."

For Jones, the technical capacity of 3D printing is inspiring him to think differently. "It could literally change our daily perceptions, change our lives. Because, who knows? We don't know what we haven't thought of yet. Just the thought process -- that I can do that --stimulates a part of my brain that is more creative than it was six weeks ago."

One of Jones's favorite customers is a team of two students, old friends who grew up together, who got a grant to work together to build a robotic hand. "They're so funny; it's kinda like the Big Bang Theory -- you know, they make jokes that nobody else gets."

"They're really good guys," he continues, "and they're just really smart. And I like them. And it kind of gives me hope, because, you know, I don't interact with those people that much. They're just uber smart guys. They have this big plan to ultimately get it so reacts to your skin.

"You know," he adds, "their dreams are different from my dreams." But Jones, with his machine, is helping to get them there.
