Brooklyn-based MakerBot hit the jackpot.

The 3D-printer maker, which just opened fancy waterfront industrial digs, was acquired by another giant in the industry, Stratasys.

MakerBot, co-founded by Bre Pettis, sold for more than $400 million. Stratasys is paying for the merger by issuing 4.76 million new shares.

The deal includes incentives for another $200 million in earn-outs.

MakerBot, which is one of the pioneers of the 3D printing revolution, has become a darling in New York’s tech scene, and there had been fear that a sale could signal the end of its presence here.

The company said it’s staying put.

“Stratasys loves that we manufacture here, and we will remain,” a company spokeswoman told The Post.

MakerBot’s success has helped a manufacturing revival of sorts in the area.

It builds 3D printers and runs an online store to download designs for 3D printed goods.
