3-D printing on the cheap

Three dimensional printing doesn't require thousands of dollars or a trip to a MakerBot store. Hobbyists and even businesses are using printers that cost a few hundred dollars to print 3-D objects.

Staten Island, New York-based small business Deltaprintr sells 3-D printer kits that, in conjunction with free software, allow users to build toys and other objects with layers upon layers of heated plastic.

Deltaprintr owners tend to be students, schools and hobbyists, CEO and founder Shai Schechter said in an interview with CNBC.

The printers are sold as an unassembled kit for $499 and an assembled 3-D printer for $685. By comparison, the price of the MakerBot Mini 3-D printer is $1,375.

To keep costs low, some parts of the Deltaprintr kit, like bearings, screws and other small components, are bought off the shelf, and other parts that need to be laser-cut, like wood and acrylic, are custom-made in-house, Schechter said.

"I used to take electronics apart in my house in order to understand how things worked, Schechter said. "And that's what we're focused on ... to make a product that people won't just use but they will understand how it works."

Deltaprintrs only print plastic objects, according to Schechter, using strands of plastic filament priced at $35 for a 2.2-pound spool.
