This is main SLS process machine. It builds solid
3-dimensional parts out of 3D
Systems’
DuraForm laser sintering powder. This guide
covers two SLS system models: the
s
Pro 140 and
the taller
s
Pro 230 . These two models are the
same with one exception: frame risers installed
on model 230 enable it to build taller parts in a
taller RCM .
See RCM Description on page 108 for more about
RCM models.
