Create Raft – A raft is essentially what it says, a "raft" of material that your part will print on
top of. Rafts are most often used when printing a part that is having bed adhesion problems due to its
geometry. For example, if you're printing a part that sits on small feet, a raft would come in handy if
the initial layers of the feet don't stick very well.
In the image below, you'll see an example of both support material and a raft.
Fig. 22-5: Support material and raft.
I took the little test cube and through a little manipulation, printed it tilted at 30 degrees. I took
this opportunity to also demonstrate what a raft looks like. This one is exaggerated in its size, but gives
a great example of what a typical raft will look like.
The image to the right should give
you a pretty good idea of what the part
looks like from the side. You can easily
see the support material as well as the
