Poor adhesion only for first couple of inches

I have a QIDI Tech 1. It has a heated bed, and a cooling fan attachment. Whenever I print without a raft, the first inch or two of material laid down does not adhere to the bed, but the rest of the first layer is flawless. I have tried speeding up…

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.…
