The first and second spray devices are arranged to deliver droplets of a first liquid including at least one biocompatible polymer through the first spray device and to deliver droplets of a second liquid including a nonsolvent for the polymer through the second spray device in an overlapping spray pattern on a substrate at a pre-selected distance and a pre-selected relative translation speed.
