CHAPTER 8. OPERATIONAL TIPS 220
Polar 3D, measure precisely the diameter of your filam ent with
a cal i per. And know what temperature is best for your fila-
ment, and be sure to set the printer ex t r u der temperature ac-
cordingly. See Polar Cloud PRINT SETTINGS to adjust for a
di↵erent fi l am ent diameter (under “ADVANCED”) or temperature
(under “BASIC”).
8.4.1 Types of filament
Note that while th er e any many di↵erent and interesting types of
filament, di↵erent types of filament have di↵erent requirements
for printing: know your filament’s characteristics.
Just a sample...
For instance, glow-in-the-dark PLA filament is fun for stu-
dents. But be aware that it is typically: (a) fairly abrasive
on t h e extruder nozzle – be prepared to replace your extruder
nozzle if you perform much glow-in-the-dark printing, (b) more
expensive than regular PLA,and(c)greenandblueglowe↵ects
are generally more satisfactory than other colors. Some users
recommend that best glow e↵ects resu l t from objects that are
fairly hollow but with thicker walls, so consider slicing objects
using no (or very little) infill while ad d i n g a few more shells than
usual.
Similarly, color-changing PLA filament – changing color in
response to temp erature or, for some brands, in response to
UV light – can be fun for students. It also tends to be mor e
expensive than regular PLA, but unlike the glow-in-the-dark
PLA, does not tend to be especiall y abrasive.
