Design Considerations
-
Consider hollowing or adding internal lattice structure to large solid pieces to improve accuracy and minimize cost.
-
See full design guidelines for additional considerations, including clearance, functional assemblies, interlocking parts, hollowing and lattice structures, ducts, threads, how to minimize the risk of warpage, bonding parts, and more.
-
Hinges, sockets, and linked parts can be integrated into the design.
