Today, ColorFabb has informed us of a 3D printer which they have partnered with. It's called the STACKER and it is a modular 3D printer which can expand in size and can have up to 4 extruders added. This allows the printer to print objects of all different sizes, and print up to 4 of the same parts at once in the same time other printers would take to print just one.

The standard model has a build size of 250 x 450 x 220mm, but the Z-axis can be expanded up to 600mm in height. It also has the option for casters (wheels) and different nozzles for different print jobs and materials.
