SHELF-STABLE BUILD MATERIALS FOR 3D PRINTING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240317909 titled 'SHELF-STABLE BUILD MATERIALS FOR 3D PRINTING

Simplified Explanation: The patent application describes build materials for 3D printing that can produce articles with high tensile strength and heat deflection temperature while remaining stable on the shelf.

  • The polymerizable liquid in the materials contains at least 20% isocyanurate polyacrylate, a photoinitiator, and a crystallization inhibitor to prevent crystallization over time.
  • The materials are designed to maintain their properties over a period of 28 days at a storage temperature of 5-10°C.

Key Features and Innovation:

  • High tensile strength and heat deflection temperature in 3D printed articles.
  • Shelf stability over time due to the inclusion of a crystallization inhibitor.
  • Polymerizable liquid containing isocyanurate polyacrylate and a photoinitiator for effective 3D printing.

Potential Applications:

  • Aerospace industry for lightweight, high-strength components.
  • Medical field for custom implants and prosthetics.
  • Automotive sector for durable parts with high heat resistance.

Problems Solved:

  • Maintaining high tensile strength and heat deflection temperature in 3D printed objects.
  • Preventing crystallization in build materials over time.
  • Ensuring shelf stability of polymerizable liquids for 3D printing applications.

Benefits:

  • Enhanced performance of 3D printed articles.
  • Increased durability and heat resistance.
  • Improved quality and reliability of printed components.

Commercial Applications: Potential commercial applications include:

  • Manufacturing of aerospace components.
  • Production of medical devices and implants.
  • Fabrication of automotive parts with high heat resistance.

Questions about 3D Printing Build Materials: 1. What are the specific advantages of using isocyanurate polyacrylate in 3D printing build materials? 2. How does the inclusion of a crystallization inhibitor improve the shelf stability of polymerizable liquids for 3D printing?


Original Abstract Submitted
