Support structures can be important in 3D printing as the method of printing one layer on top of another means
that if there is an overhang within the model (where the layer being printed has nothing underneath to rest on) then
this can cause a print to fail.
To print with supports on the Polaroid PlaySmart is easy; you simply tick the box that says 'Enable Supports' when
you click Print. This will turn on the default supports, which places them anywhere on your model that has an
overhang that is more than 30° from the vertical.
If you wish to adjust some of the support settings yourself then you can do so under the Advanced Settings. These
include being able to adjust the type of support (default is a line support, or if more support is needed you can
change to a grid structure), and also adjusting what angle the supports will initially be applied from, as well as
other more advanced settings.
Under the Advanced Settings you can also adjust the way that your model is printed.
With this form of 3D printing, models are printed with a solid outer wall, surface and base and then a grid infill
(i.e. it isn't solid throughout). Under the Properties section of the Advanced Settings you can adjust some of these
features.
Shell thickness allows you to adjust how thick the outer walls of your model are in millimetres.
The fill density adjusts the grid inside the model. The default is set to 15% but if you wanted a completely hollow
object you can slide this down to 0%, or for a more solid object simply slide the scale up towards 100%.
The other 'Properties' setting is to adjust the number of layers at the beginning and end of each print. This is default
at 6 layers but can be adjusted up or down accordingly.
