Overview about Pre-heating Concepts for LPBF
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.
- 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.
