Has anyone tried to build a custom powder bed for layer manufacturing or
found a ready to implement solution on the market? Any information on the
matter or point to the right direction would be appreciated.

Thank you in advance,

Hi Nikolaos:
Sophisticated users in dentistry and aerospace seem to have made many
modifications to both 3DP and laser sintering and related technologies for
specific applications. There's plenty of IP, but not so easy to dig out from
the pile, and not so easy to know if they're actually doing it. For
example, Boeing had a patent issued this quarter describing a build platform that
can be mechanically deformed to compensate for geometric distortions. This
is said to be especially useful for larger parts and to overcome warping.
See US8,206,637.

They've also done inserts that make the original chamber smaller or provide
 it with different capabilities.

You might get a better response if you describe more thoroughly what
you're looking for.
