Like most exclusive users of PLA, I've been on the hunt for something to help smooth PLA like acetone does to ABS. Based on some suggestions I've read (here and elsewhere) I decided to give Acrylic Cement a try. I used a junk PLA part I had laying around that was horribly layered due to my print bed being out of alignment. In this experiment I simply used a "dunk" method, lowering one end of the part in to the Acrylic Cement for about 20 seconds and then letting it air dry. Overall, I'm quite pleased with the results. I also used the cement to weld together a couple of pieces of PLA and it's indeed like super glue. It seems I finally have something I can use to splice together several rolls of PLA I have laying around with only 30' or so of filament left on each. I have not tried vapor smoothing with the cement as I don't know if it will work any better. Anyone have experience with that?


Right half of the part is where it was dipped in the chemical
