Model Design for Re-Use
This chapter's purpose is designed to get you thinking in terms of model re-use.
Positive and Negative Space
Keep 'em Separated
- Design your object body parts separate from your object holes
Model Design for 3D Printing
Orient for Your Strengths
- Many 3D printing processes are strong in two of three dimensions. In fused deposition modeling (FDM) techniques like those used in MakerBot and RepRap printers, the Z-axis is weakest to shearing forces.
- Design long, thin parts in the XY plane.
- Consider orienting irregular shapes at a diagonal X-Z or Y-Z angle for compromise.
Over Hangover
Teardrop Tunnels
- Design in 45-degree maximum overhangs in horizontal holes using tear-drop and truncated tear-drop shapes.
