Enhancement of 3D Printing Techniques through Spectral Shaping ID: 2020-053

This invention revolutionizes 3D printing by introducing spectral shaping to align resin properties with optical sources for multi-resolution printing.

Technology Overview

The technology focuses on improving Digital Light Processing stereolithography (DLP-SLA) through two main innovations: Spectral Filtering in 3D Printing and Multi-Resolution Printing. Spectral filtering ensures the resin absorbs the full light spectrum, enhancing z-resolution for detailed features. Multi-resolution printing is achieved by using two spectrally filtered light sources, allowing for different resolutions and fine control over the printing dimensions, thereby overcoming previous limitations in 3D printing resolution and speed.

Key Advantages

• Enables high z-resolution crucial for producing small, detailed features
• Facilitates multi-resolution printing by switching between optical sources
• Broadens the usable range of absorbers, including biocompatible options
• Increases printing efficiency and resolution flexibility

Problems Addressed

• Overcomes reduced resolution in the z direction, a common limitation in traditional 3D printing practices
• Resolves the challenge of aligning resin absorption spectra with the optical light source for improved detail and efficiency
• Addresses the need for biocompatible absorbers without sacrificing resolution

Market Applications

• Microfluidics and lab-on-a-chip devices
• High-resolution biomedical implants and prosthetics
• Customized components in aerospace and automotive industries
• Educational models and prototypes requiring high detail
