Vaporization-Defined Geometry in Additive Manufacturing ID: 2021-053

An innovative method enhancing additive manufacturing by using vaporization to define geometry boundaries.

Technology Overview

This technology introduces a method for enhancing additive manufacturing processes by defining geometry boundaries within powder beds through the vaporization of a volatile liquid, such as water. By penetrating the powder with a volatile material and rapidly vaporizing it using a localized energy source, the method creates a trench between the part and excess powder without melting the powder. This process results in improved dimensional accuracy and surface finish, and it allows for faster processing speeds compared to traditional methods.

Key Advantages

• Improved part definitions and dimensional accuracy
• Faster processing speeds with laser scanning
• Reduced wear on equipment
• Potential to eliminate the need for expensive inkjet printing equipment

Problems Addressed

• Reduces the need for physical cutting tools in additive manufacturing, lowering equipment wear
• Enhances surface finish and dimensional accuracy beyond traditional methods
• Speeds up the manufacturing process, enabling faster production times
• Eliminates the requirement for expensive binder jetting or multi-jet fusion equipment

Market Applications

• Enhancement of powder bed fusion systems
• Improved manufacturing techniques for polymers, metals, and ceramics
• Standalone fabrication methods for advanced manufacturing
• High-speed production environments without reliance on inkjet printing
