e^–MELT^® Benefit#3 ProHeat^® preheating for fine and smoke-sensitive powders

e^–MELT^® benefit #3, Fine and smoke-sensitive powders can be used, thanks to patented ProHeat^® preheating technology.

Freemelt introduces a new era in Electron Beam Powder Bed Fusion (E-PBF) with its patented preheating technology, ProHeat^® . This innovation allows for charge-free heating of the powder bed, effectively preventing smoke during the build process, and enabling the use of powders smaller than 45 micrometers, thus bridging the gap between E-PBF and Laser Powder Bed Fusion (L-PBF).

By utilizing the ProHeat^® technology, we also eliminate the need for expensive high‐purity gases such as helium or argon.

Watch this video to see ProHeat^® preheating in action, captured in the complete E-PBF layer sequence, including recoating, preheating, and melting.
