Investor, Do you know SLM/EOS Machine Cost?

But do you happen to know the average price of an SLM and EOS machine ? I am assuming they are MUCH less than an Arcam machine which is around $800k USD...I am hoping this explains why they are able to sell so many more machines than Arcam... I don't have time right now to go dig it up... but thought you might have it at your fingertips...

Cheers

It's not just the size but also the shape of the powder particles. Spherical particles lead to fewer voids but most voids are caused by [the low percentage of] hollow particles in the Arcam powder. Spherical voids do distribute stress better than voids with sharp corners but it's still best to remove any voids with HIP or complex die-forge methods.

There's a paper out there somewhere showing fewer defects with the small spherical particles that Arcam produces. Couldn't find it just now.
