I actually made one myself and that's normally what I use. It's just that with tissue that bonds as it cools, it seems the high pressure in the press would be ideally suited to the cooling period.

It all seems a bit counterintuitive to me. It means all you're using the press for is melting the tissue, and the bonding occurs after the print is removed from the press, when really the bonding phase is when the print should be under maximum pressure.
