The orientation
Let's begin with a consideration about the orientation of 3D files in relation to the printing surface: the object is built layer by layer and so each new layer is supported by
the one previously built. When a wa ll or a surface is tilted over 45°, or some parts ar e built without la yers supporting them (floating in the void) you are in front of a
model that requires some specific expedients. The first question concerns the possibility to rotate the model in relation to the printing direction to improve or resolve
the issue of the overhangs.
May be necessary rotations of 90 or 180 degrees, thereby changing the part resting on the printing bed. In general, if you can find an orientation that allow a flat surface to
be in contact with the printing plate, it would be better for the attachment of the object to the plate during the printing process.
Let’s take the model of a door for example: printed in its natural position (vertical) would have a thin support, on the contrary, lying would potentially have a contact
surface much wider and stable. May however be details (such as the handle, for example) that do not allow the laid orientation: in this case we suggest that you remove
the handle to print it separately, connecting it after with a glue to its original position.
Cutting the object
There are cases in which you need to print in a single piece, but there are many cases where it is possible to cut into pieces the object to print it in an easier and better
way.
An example often seen on the internet is the Eiffel Tower: for its height you would force it to print as a whole and with small details too tiny to be created by most FFF
printers. Cutting the the model into two or three parts you can instead place it in the print volume of almost all printers and metal structures would be large enough to be
printed accurately. The parts can be easily combined with glue after, thus having the tower perfectly printed and defined.
The support material
When you can not avoid suspended parts, overhangs or beginning in void you have to give the printer a support on which to begin creating these parts. The material
support are the solution that technology has developed to overcome the force of gravity and allow the creation of complex models, with white parts suspended and
inside of other parts (the bearing balls) , or with elements that necessarily begin (moving from bottom to top) from nothing, as the arms do not rest against the
flanks in a bust.
In some cases, the problem can only be linked to a detail and then you can create already in the model solution. Take the case of this famous model, thanks to an
