Module 5: Powder Based 3D Printing Processes

2025?m

Which of the following processes uses an electron beam for melting metal powder?

(i) Laser Engineering Net Shaping (LENS)
(ii) Electron Beam Melting (EBM)
(iii) Binder Jetting
(iv) Fused Deposition Modeling (FDM)

Worked SolutionAI Assisted

Answer: (ii) Electron Beam Melting (EBM)

EBM uses a focused electron beam to melt or fuse metal powder selectively in a vacuum environment. The beam scans the powder bed according to the sliced geometry, building the metal component layer by layer.
