The FDM 3D printers melt plastic and extrude it in a pattern to create a 3D object, building it up layer by layer. They can create physical representations of any 3D digital model. The StrataSys F170 is an industrial grade FDM 3D printer with a build volume of 10”x10”x10”. The StrataSys can print in layers as thin as .127mm in ABS and as thin as .254 in PLA. You should use the Stratasys for larger and more complicated parts with tighter tolerances than the Ultimaker can handle.
