What are suitable pre-heating concepts for L-PBF and what are their potentials?

Challenge and Motivation

• Pre-heating of LPBF parts reduces distortion and enables manufacturing of materials susceptible to cracks (γ-TiAl, MAR-M 247, …).
• State-of-the-art concepts lead to decreased build area temperature with increased built-height.

Objective

• Using pre-heating in LPBF has potential to decrease part deformation and extend processible material range.
• Temperature in the build area has to be constant during process.
