On the heels of the Arduino announcement, MakerBot Industries announced their new plastic extruder, the Stepstruder MK 7, the “highest number extruder ever.” It’s significant because it’s the first extruder designed from the ground up for 1.75 mm filament, and it’s much smaller than previous extruder designs.
The small size of the MK 7 means that you can even fit two heads in your ‘Bot. In that vein, MakerBot was also showing off an experimental version of their printers sporting dual Mark 7s and software for rendering 3D objects in two colors. The software is in “experimental public beta,” but with the software, two Mark 7s, and a few tweaks, and you can be a beta tester.
Announcement on the Stepstruder MK 7 here and more about the public beta of the dual-head version soon.
