Understanding Infill Patterns in 3D Printing

What is Infill?

Infill refers to the internal structure of a 3D printed object. Instead of printing solid objects (which would be heavy and expensive), 3D printers fill the interior with patterns that provide structural support.

Infill Percentage Guidelines

• 10-20%: Decorative items, display models
• 20-40%: General purpose parts with moderate stress
• 40-60%: Functional parts that need to handle some load
• 60-80%: Strong mechanical parts
• 80-100%: Maximum strength for critical components
