One of the leading 3D printer manufacturers, Printrbot is known for low-cost, open-source, wood-framed machines. The new machine marks an evolution for the company, founded after a successful run on Kickstarter two years ago.
Foremost is the aluminum and steel frame, just slightly larger than the current laser-cut plywood Simple, and powder-coated in an eye-catching red color. The print bed has grown, too, now supporting prints up to 6″x 6″x 6″. (The wood Simple is capable of 4″x 4″x 4″ prints.) The increased print size is due in part to new Z-axis rods, grown from 8mm to 12mm — in a visit to MAKE, Printrbot founder Brook Drumm explained this makes them rock solid.
