If I'm understanding this correctly, there won't be a way to print hollow parts, right?

  No. The sintering happens layer by layer. So you can print hollow parts.

    I think the parent comment was concerned about having a closed chamber full of powder when the print is done

    You can print them, but the "hollow" chamber you print will be full of powder with no way to remove said powder. That's a well-established limitation of both SLS and SLA printing. The classic way of getting around that is to leave a small hole in the chamber that's open to the outside - then you drain the powder out of that hole and, if needed, plug it up after you're done.

  Not directly like FDM, but my understanding is you can design the part with "escape holes", so it's possible in certain circumstances.

  Why not? Or do you mean infill?
