I did print 2 bumpers at the same time, treated one with the xylene vapour bath, and left the other untreated - so it is my control. The treated bumper is certainly not as rubbery as it was a week ago, but it is still flexible/bendable compared to the untreated one. I can happily twist it into a figure 8, but the control made a cracking sound when I tried just now (only got half way through the figure 8 twist). Will let you know in another week whether it is getting harder.
i had deducted that from other experiments and reading the MSDS of all the common chemicals that had the same effect. now if you would do me the favor, let me know if it remains flexible over time. the things i had treated also become rubbery, but they go back to a normal hardness after a few days, a week the longest. keep the treated bumper out in air and report back to me in a week or so. my guess is that it will harden again.
I printed a cell phone bumper (http://www.thingiverse.com/thi... in PLA and sat it in an un-heated Xylene vapour bath over night. It worked a treat making the bumper very rubbery, so xylene is the way to go. Also there was no noticeable discolouring when in exposed to vapours, but I did get some whitening when submerging in the xylene. Good work.
