Build  optimization  is  dependent  on  a  part’s  function  (conceptual  model,  functional prototype, manufacturing tool or end-use part). Based on the part’s function, the user must select the appropriate orientation to balance or optimize surface finish, strength or build time of the part. 


1.1. Surface Finish 

Part orientation impacts surface finish due to the process of slicing and printing
the part in increments in the Z direction. Orienting the part so that curved or
angled surfaces are built parallel to the Z axis will result in smoother surfaces.  

1.2. Strength

Proper orientation of a part can dramatically increase feature strength. Small
features can become stronger by simply rotating the part. Generally, orienting a feature parallel with the build layer maximizes feature strength.

1.3. Speed

Part orientation can affect support material usage and build speed of the part.
Rotating a part to a different orientation can decrease support usage and the
build time of a part.
