Although the Polaroid ModelSmart
250S 3D printer has only one extruder,
you can easily print models in multiple
colours.
By selecting Multi Colour in Polaroid
Prep or opening the door mid-print, the
print will pause. At which point there is an option
on the LCD screen to change your cartridge, this
allowing you to change colour.
Alternatively, if you want to be specic about where
your new colour starts on your print, you can pre-set
the printer to pause. You can do this by pressing the
Multi Colour button in Polaroid Prep; this inserts a
‘pause’ onto your bed (seen as a pink layer). You can
then move this to where you want it on your model,
either by using the slider, or by typing in a position
in millimetres (working from the bottom of your
model upwards) or even a percentage point. You can
set as many pauses in your print as you like. You can
also easily space these equally by clicking the Auto-
Arrange button.
