Not trying to start a war here. Don't forget, I'm long and heavy SGLB.
I view EBM and DMLS as equal technologies. They each have their strengths and weaknesses and are deployed for different reasons. For instance, another strength of EBM is that it can print TiAl where DMLS cannot.
My emphasis was on Arcam. Who IS contracting with the big guys. In fact, many of the same big guys as SGLB. GE is already using Arcam machines to print LPT blades.
I'm heavily invested in both technologies. It's my hope that PrintRite3D will be ported to the EBM process soon after the release of DEFORM.
