# One-Pot Dual-Wavelength 3D Printing Breaks Free from Support Constraints

## TL;DR

This paper introduces a new 3D printing method that uses two light sources to create structures without needing support material.

## Contribution

A novel dual-wavelength 3D printing technique that eliminates traditional support material through orthogonal light sources.

## Key findings

- Freestanding 3D structures can be fabricated using dual-wavelength printing.
- The method avoids the need for traditional support structures in 3D printing.
- Orthogonal light sources enable precise and complex shape fabrication.

## Abstract

The Page and Huang groups employ orthogonal light sources to fabricate freestanding
3D structures that eliminate the need for traditional support material.
