7.2.1.1 Hardened steel nozzle
Hardened steel nozzles are a must for highly abrasive materials. Regular brass nozzles will
degrade very quickly and lose their properties.
Most of the abrasive materials are composites, plastics with something mixed in. Some
examples are ColorFabb XT CF20, ColorFabb Bronzefill, ColorFabb Brassfill and some glow
in the dark filaments. Always ask your filament vendor if you are not sure. Slight
disadvantage is that some standard materials like ABS isn't possible to print as fast as with
regular nozzle.
7.2.1.2 0.25mm nozzle
To get finer detail on 0.1mm or 0.05mm print settings, you can use 0.25mm nozzle. But use
it for only very small objects, only couple centimeters big. The print time can be considerably
longer compared to 0.4mm. Ideal use is jewelery.

9 Printing your own models
9.1 Where you can get the 3D models?
The best way to get started with your own 3D
printing
is to find already created
models
on
internet
they should be in the
.stl
or
.obj
format . Fortunately there are lot of fans and there
are sites from which you can download a wealth of readymade 3D
models
from a simple
shaver holder to a
detailed
aircraft engine
model
.
3D
models
are generally free to download under the
