Stratasys, the Minneapolis and Israel-based 3-D printing giant acquiring Brooklyn-based competitor MakerBot, relies on Weber Shandwick for outside PR counsel.

makerbotStratasys said June 19 it will acquire MB for $403M in stock in a deal to drive faster adoption of 3D printing technology, which allows users to "print" objects and parts from a computer to construct three-dimensional objects.

MB, founded in Brooklyn's Boreum Hill section, this month opened a new 55K-square-foot manufacturing facility in the borough's Sunset Park district.

WS, which is supporting media relations for the merger deal, handles Stratasys out of its Minneapolis and Chicago offices.

Stratasys last year merged with Israel's Objet to create an 1,100-staffer 3-D printer and materials maker.

MakerBot, which runs the popular site for downloading digital designs for printing, Thingiverse.com, said it has sold around 11,000 of its 3D desktop printers in the past nine months for professional and personal use. First quarter revenue was $11.5M, compared with $15.7M for all of 2012.

Stratasys shares were up $1.12 to $85.72 in afternoon trading June 20.

MakerBot's printers retail from $2K-$3K.
