10.3 Modeling with 3D printing in mind
Modeling for 3D printing presents several interesting challenges.
10.3.1 Overhangs and support material
The most important thing to keep in mind while modeling for 3D printing is support material.
3D printers can’t print in mid-air, each layer has to be laid on top of the previous layer. When
designing, keep this limitation in mind and try to avoid creating steep overhangs. That said,
short horizontal bridges can be printed without supports.
