According to some recent vendor literature, the strength of parts is
improving. They claim to have a feedstock material now that's some
sort of metal, coated with plastic. After you stick the plastic
together with the laser, you fire it in an oven; the metal sinters.
This leaves a porous structure. You then put some copper stock on it
and put it back in the oven at a lower temperature, and the copper
melts and wicks into the pores. This claims to make injection molds
that last for 100K cycles. I don't remember if they said there was a
polishing step, but I would think there would have to be.
