MakerBot Industries, the fast-growing maker of 3-D printers, is in talks with suitors that could lead to the sale of the New York-based company, people familiar with the matter said.

The 4-year-old startup was recently gauging its options for raising a new round of venture capital when the discussions led to interest from possible acquirers.

The talks are continuing, but it is far from certain that they will lead to an acquisition, sources said. Ultimately, MakerBot, whose investors include Amazon CEO Jeff Bezos, may end up raising more venture capital to continue building its business instead of cashing out.
