Is packing multiple prints into the build volume a feasible workflow for powderbed printers?

With fdm printers, the 3D object that should be printed can be positioned anywhere in the build volume. But it's only practical to place it on the bottom, because otherwise support material would be necessary. stereolithography has the same problem.…

Frightened of Cheap Chinese Power Supply as I hook up the heated bed

My 12V DC 30A Power Supply 360W Power Supply is really cheap, and it's worked well for setting up the motors; but now that I'm on to the heated bed, which uses considerably more Ampage than that of just the motors, I'll confess, I'm getting…
