"I knew that was going to happen. I also knew that I couldn't say anything," MakerBot CEO and cofounder Bre Pettis told Valleywag this morning at the grand opening of the company's new 50,000 sq. ft. production facility in Sunset Park in Brooklyn. Pettis was referring to a question about yesterday's report that MakerBot was in acquisition talks and might sell rather than raise more venture funding.
