Helisys is no longer in business ... but Michael Feygin is around. In the
day their LOM units were reasonably expensive but used very inexpensive
consumables ...

Let's see

Buy an expensive machine that then requires expensive consumables, tied to
the machine by the usual "Using anything else invalidates your warranty"
and the machine creates items that look the part but are unusable.

I think I can understand a certain degree of reluctance by folk without
cash to burn...

The fact that it is a standard commercial exploitation technique I guess is
irrelevant.

I must admit to struggling with the concept of RP when you look at it like
the above, much as I fancy it as a fun toy.

RM though that is an entirely different matter..........
