Arduino Materia 101
this print requires more time to cool (and
should be printing at a slower rate) or
the model could be achieved at a higher
speed. Another important parameter is
the flow rate that increases or decreases
the amount of material extruded. This is to
compensate for any changes in the diameter
of the filament wire. The flow rate can also
thicken or thin out the walls of the model.
The “Fan Speed” parameter makes
it possible to adjust the airflow
on the object being printed.
detaching the 3d
Printed ObJect
When your print is finished, Arduino Materia
101 lowers the print bed and parks the
extruder. Now you have easy access to the
print surface to detach the finished object.
This is a delicate and inevitable operation.
Because of the way the object is printed, it
is necessary that the first layer adheres well
and remains clinging to the plane for the
duration of the print itself. If the bond was
not good, mechanical stress and vibrations or
even a small nudge from the extruder would
detach the print and consequently ruin it.
Detaching the model thus requires a
certain expertise and some tools such as
a thin spatula or a box cutter (Fig. 2).
Be careful when removing the object
with these tools. It is recommend to
wear protective gloves to avoid cuts
from the blade or the glass plate.
Try and insert the blade a few millimetres
under one side of the printed piece, then
with a horizontal movement, without trying
to lift the piece, move the blade towards
the opposite side of the print. Usually the
piece comes loose without much force and
without you reaching the other side. If the
model has thin leg parts touching the surface,
you should detach these first without lifting
them and then detach the part with the
broadest base. In this way you avoid breaking
the thin parts. In the case of vessels or parts
with a single wide base, start on one side,
trying to insert the blade deeper and deeper.
Do not push the blade directly in but use an
oscillating movement to advance the blade.
Avoid pulling on the printed object or
using it as a lever, because it could break.
If the printed object has a big base surface,
you can remove the glass print plate and
place it under lukewarm water to allow
the hairspray to dissolve and allowing
the easy removement of the object.
Remember that the extruder is warm just
after the print is done.The extruder’s solid
brass nozzle remains hot for several minutes
at temperatures sufficient to cause a burn.
Look at the temperature on the display and
avoid any contact with the nozzle as long as
a it indicates a value higher than 50 degrees.
If in doubt, do not detach the piece until the
temperature has dropped to safe levels.
