When Supports Are Unavoidable

Construction scaffolding
Support structures work like construction scaffolding

Sometimes complex shapes require supports. Here's how to handle them.

Support-Requiring Features

  • Arms on figurines
  • Bridges over 50mm
  • Floating elements
  • Complex organic shapes
⚠️ Warning
Supports leave marks on your print where they attach. Design with this in mind - hide support contact points on less visible surfaces.

Design Alternatives

Before adding supports, ask:

  • Can I rotate the model?

  • Can I split into parts?

  • Can I add a chamfer?

💡 Tip
Splitting a model into parts that print flat, then gluing them together, often produces better results than using lots of supports.
