"It builds one layer, extrudes it out, pops up again, extrudes another layer, pops up again, makes another one until in the end the final object is made," Daniel Riley of Blu Bin Inc. is talking about his 3D printer.
One thin layer of plastic at a time, 3D printers can create just about anything you can imagine.
The endless possibilities are drawing spectators to a new, yet-to-open retail shop on Burlington's Church Street.
"It's weird!," says Taylor Pears who checked it out through the store window.
"I'm very interested in these 3D printers it's amazing technology," says tourist Guillaume Ozoux.
"I imagined that it would use kind of like one as a model and make the second, but I guess with a computer you can do just about anything," says Leena Maloney who is visiting Burlington.
Blu-Bin Inc. first opened in Poultney last year, when owners say they became the first-ever retail 3D printing shop in the country.
Now Riley and his business partner are bringing the experiment to Burlington.
"In our previous shop we made everything from iPhone cases to replacement parts to proto-types all that kind of stuff. I think that being in a college town, custom iPhone cases are going to be a big one," says Riley.
For now, they're making demo prints.
But when doors open September sixth, a custom iPhone cover will cost you 20 dollars, with most prices for other items based on time and materials.
There are a few limits to what can be made.
Size can be a factor, and the business will be avoiding gray areas involving copyright and weapons.
"Being from Connecticut and having been affected by recent events there, I really don't think we should be making guns," says Riley.
Many we spoke with say they don't even know what they want made, but will be back.
Others say they want their own copy of the printer for their garage.
