The tech scene is booming in Brooklyn. 
Over the summer, 3D printing company Stratasys acquired MakerBot, the hot 3D printing startup, in a $400 million deal. 
"We're so proud to be doing this in Brooklyn," MakerBot CEO Bre Pettis said in June. "I don't think we could've done this any other place."
In Brooklyn's DUMBO area, there is a growing community of tech startups. The area, which stands for Down Under the Manhattan Bridge Overpass, is home to more than 500 tech companies.
