Additive manufacturing provides opportunities for improving properties of existing alloys and developing new material compositions. Materials produced with powder bed fusion (PBF) often exhibit unique microstructures, due to the small melt pool and rapid solidification associated with localized beam melting.
However, most commercial PBF systems are intended for production only. They are not designed for small scale experiments and have limitations in terms of beam control.
This paper describes a new e-beam PBF system for R&D currently developed by Freemelt AB. This system has benefits such as
- open source software providing unsurpassed freedom to explore innovative melting strategies
- small build volume and low powder consumption
- short turnaround time
- high tolerance to powder quality
- outstanding vacuum for highly reactive materials
- high powder bed temperatures for poor weldability materials
- easy attachment of R&D equipment, e.g. RGAs or X-ray spectrometers, for in-situ process monitoring.
