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.

Diamonds at Any Angle
