an object.
For some ob jects, printing with a raft may better allow re-
moval from the build plate without damage to the bottom of
the object.
After removing an object, check whether it is time t o clean
the build plate and/or apply more hair spray (or other adhesion
aid).
8.4 Filament
If you have a Polar3D printer and have filament from a previous
3D printer, you are in luck! Polar 3 D does not use proprietary
filament. This means that as long as you have 1.75mm diameter
filament, your Polar3D printer can print it.
Note that we s tr o n gl y recommend use of PLA filament in the
classroom as it: (1) is easier for begin n er s, and (2) does not
require ventilation.
Our other suggestion is that when it comes to filament, cheaper
is not always the best choice. An extra cheap roll of filament
may not have the same print quality as the Polar 3D filament,
or other standard brands of filament. For instance, you may
find particles within the filament cause jams in the 3D printer,
making it an annoyance to keep cleaning it out; (see Section
10.3). Or filament whose diameter does not remain consistent
may result in lower quality prints.
Especially if you’re using filament from a supplier other than
