Surface finishes
The capacity to produce minute details depends on the manufacturing technology.
Thin walls
It is important to maintain a good height/width ratio to ensure wall stability.
Warping
Some materials suffer internal stress when cooled and produce warping. This must be considered in the design process.
Overhang
Walls with an inclination bigger than 45º can collapse and supports are necessary in these cases.
On the other hand, there are also some limitations or possible problems to consider in the designing process.
