The Printrbot Metal Plus is the bigger sibling to the Simple Metal and should feel very familiar. Even with a bigger build area, the Plus still has a surprisingly small footprint. It’s simple minimalistic design that has a bigger build area, upgraded Linear rail System, and of course a sturdy powder coated metal frame. The linear rail and carts offer smooth stable movement of the print head and bed. The machined aluminum bed is extremely flat, with a large build area that can produce prints up to 10-inch cubes.
