The little plastic thingy on the bottom of the blender broke. The loss of Barbie’s hairbrush has Suzie in hysterics. And a miniature replica of your client’s dream house would really help seal the deal.

Want to make it happen in the privacy of your own home office?

Enter the 3D printer. Once the product of futuristic sci-fi movies, these machines of modern technology are now available to the everyday consumer and open up the possibility of creating some amazing things.

Justin Leone, of Northhampton, brought his MakerBot Replicator 2 3D Printer to the Mattapoisett Library on Saturday and demonstrated some of its capabilities. (And yes, it does beep like R2D2.)

Leone, who has a background in 3D modeling and animation, purchased the printer for $2,200 several months ago.

“I’ve been following this technology, and I waited for it to get cheap enough and a high enough quality that you could make a viable product out of it,” he said.

Using spools of biodegradable plastic, the machine creates a design by melting the plastic in layers as thin as one millimeter, from the bottom up.

There are still a few bugs though, said Leone.

In the four months since he purchased the printer, Leone has taken it apart several times. But as the kinks get worked out, he believes the machines will become as common as inkjet printers in a home office. Already, the MakerBot’s size is comparable to a desktop printer.

“In about 10 years, they’ll be pretty much ubiquitous. The norm will be, if a plastic part breaks, instead of sending out to the company to get a new one, you just download a file and print it yourself,” he said.

Leone been doing just that, even printing a replacement piece for his blender.

But creating new products from scratch requires knowledge of CAD or animation software. For the rest of us, the website Thingiverse offers hundreds of free downloadable projects that include microscopes, iPhone cases, and even a prosthetic limb.

“Everyday they’re adding hundreds of thousands of new things on there,” Leone said.

And with his mid-market machine, Leone has the capability of making pieces with moveable parts. So far, he’s made boxes, night lights, and medallions with the MakerBot.

Librarian Liz Sherry was one of many awed onlookers at the demonstration. “The field for personalization is so big,” said Sherry.

Leone agreed.

“Theoretically, there isn’t much it couldn’t make,” he said.
