Model Quality When Digital Material Mode is Used
¾ Near-high-quality is achieved for most models.
¾ If all objects on the tray are inserted from individual stl files , they are
printed with the standard resolution of 600 dpi (dots per inch) along the
Y-axis—unless glossy finish is required (see “Surface Finish” on page 23).
¾ If there is an assembly on the tray, all of the models on the tray are
printed with a resolution of 300 dpi along the Y-axis.
