dpi (42 microns)
that is significantly higher than fused deposition modeling
(FDM) 3D printers (e.g. Stratasys Dimension, Maker-
Bot, or RepRap) that are typically around 100 dpi (254 microns).
High resolution printing allows the creation of visibly
smooth models without internal gaps. Model surfaces can be
further enhanced with a manual finishing process to achieve
optical clarity. This process consists of removing support
material, sanding the surfaces with incrementally finer sandpaper,
and then buffing.
