Question

The main purpose of electron beam melting is to build up the metal parts by layer forming.

(a) True

(b) False

I had been asked this question by my college director while I was bunking the class.

This intriguing question originated from Laser and Electron Beam Melting With Rapid Prototyping topic in division Casting Process of Casting-Forming-Welding II

Answer 1

Correct choice is (a) True

To explain I would say: In this technology, first the part is designed by the 3D CAD software, and then the file is transferred to the processing software where the geometry is sliced into thin layers. The material is melted by electron beam to fit the geometry defined by the computer model. Then the metal parts are made by layers forming via electron beam melting process in a vacuum chamber.
