One technique which bears mentioning is printing in 100% infill using a filament which will allow re-heating/cooling and then putting it in a tray of powder salt (very finely ground table salt) and then backing and cooling it.

You get a solid plastic part without layer lines. This makes it about as strong as injection molded plastic.
