Optical microscopy images of the cross sections cut in the X-Y plane from the NiTi samples 3-D printed using laser scan distances of (a) 35 μm and the (b) 120 μm. The color contrast indicates differences in grain orientation. The small black spots in (b) are not porosity, but artifacts from the etching process.
