Design Guidelines
Minimum Wall Thickness
1.5mm for structural parts, 1mm minimum
Thicker walls provide better flexibility and durability
Support Requirements
Minimal supports needed due to flexibility
TPU can bridge longer distances than rigid materials
Infill Patterns
Use gyroid or honeycomb for flexibility
Lower infill (10-30%) maintains flexibility while providing structure
Post-Processing
Difficult to sand, best printed to final form
Design parts to avoid the need for extensive post-processing

Frequently Asked Questions
What Shore hardness options are available?
We stock TPU in Shore A 85, 90, and 95 hardness levels. Shore A 85 is softer and more flexible, while 95 is firmer with better structural properties.
How flexible are TPU prints?
TPU parts can be bent, twisted, and stretched significantly without breaking. The exact flexibility depends on the Shore hardness and part geometry.
Can TPU be printed with complex geometries?
Yes, TPU can handle complex shapes and overhangs better than rigid materials due to its flexibility. However, very thin features may be challenging.
Is TPU suitable for food contact?
Some TPU grades are food-safe, but verification depends on the specific formulation. Please specify if food contact is required when requesting a quote.
