Research Progress on 3D Printed Metallic Glasses Materials, Processing and Property

Abstract

Materials, processing and property of metallic glasses by 3D printing were reviewed. Two common 3D printing methods-selective laser melting and laser solid forming were introduced. The effect of process optimization, substrate preheating and re-scanning strategy on crystallization and micro-cracks was discussed. It was pointed out the balling and pore defects and elimination methods such as re-scan, anneal, preheating of powder and substrate and scan strategy can be applied to improve the properties of metallic glasses. The metallic glasses with high relative density, crack-free and fully amorphous alloy are expected to be prepared.
