I decided to use the failed test print for the main frame to try some new finishing techniques. I wet sanded the PLA up to 1500 grit and then went quickly throught he small sanding/buffing pads from MicroMesh. The result is a near glass finish without any primer or paint.
I then decided to try my polishing graphite powder straight to the white PLA. Normally, you put it over a gloss black finish, but the result is more of a black chrome/glossy gun metal finish. I wanted to see if white would result in a lighter, more traditional chrome/pewter finish. The result is pretty good considering I didn't really bother to work out all the buffing marks and scratches.
Reminder, this is straight PLA from my Creality CR-10s printed at .2 layer height and then hand sanded, and polished with graphite powder. There is no filler, primer, paint, or finish of any kind (I did a dust coat of black to see when the low spots were gone with initial sanding at 120 Grit). In total, the time from raw print to this finish was about 10 minutes.
