ADDITIVE MANUFACTURING FOR METALS: ISSUES AND CURRENT RESEARCH ACTIVITIES
Dr. Nguyen Hung, Texas A&M University, Texas, USA
Abstract
Additive manufacturing has transformed the early rapid prototyping technique to 3D printing of engineering components. This technique has revolutionized traditional subtractive methods when fabricating components by adding layers of polymers, organic materials, ceramics, or metals. 3D printing of metallic components has been commercialized and received lots of interest from industry due to its potential cost saving and ability to generate complex shaped engineering components while reducing machining skills.
This seminar reviews suitable 3D printing techniques for metals and reliability issues that prevent additive manufactured parts from directly replacing of current subtractive manufactured parts in demanding applications. Surface and volumetric defects of selective laser melted Inconel are shown, and current remedial research efforts are presented and discussed.
