Design Principles

"Design for Post-Production Adaptability: Incorporate latent reactive sites within printed structures to allow for modification and enhancement after the primary manufacturing process."

This approach moves beyond static 3D printed objects by introducing 'living' characteristics. Designers can create products with inherent capabilities for self-healing, surface functionalization, or tailored drug delivery, significantly expanding the potential of additive manufacturing.

What This Means for Your Design

Imagine a 3D printed object that you can change or improve even after it's made! RAFT polymerization in 3D printing makes this possible by leaving 'hooks' on the material that can be used later to add new features or fix damage.
