tion in the more familiar Cartesian x , y , and z coordinates;
the Polar3D printer’s firmware automatically converts from
the Cartesian coordinates describing an object to the polar
coordinates (technically, cylindrical coordinates) that the
printer’s hardware uses.
However, if you have students who are learning about polar
coordinates in their math class – see Common Core stan-
dard
http://www.corestandards.org/Math/Content/HSN/CN/B/4/
– you may wish to draw such students’ attention to the un-
derlying polar operation of the Polar3D printer, both to
help motivate them as to why one might want to learn
about polar coordinates, and to help them visualize the
relationship between polar coordinates and Cartesian coor-
dinates.
Also, a couple of operational tips regarding optimal po-
sitioning of objects on the build plate (see Section
14.1 :
Positioning objects of the Polar Cloud Guide ) will be more
intuitive if you are conscious that the printer is operating,
at the hardware level, in polar coordinates.

print head
The print head is the assembly including the heating ele-
ment and the filament extruder. It moves up and down the
Z rod. See Figure
