I broke my M90 x-carriage cooling fan bracket. One of the little lugs snapped off.
I printed a new one in PLA. (It functions much better than ABS as it's stiffer and holds the fan assy. pretty much parallel to the bed so there's a little more naked nozzle showing and less chance of catching.)
I printed the bracket again with some Taulman 618 nylon just for fun.
At a nozzle temperature of 238C the result was acceptable (after a bit of clean up to remove trails) and incredibly tough. There was a bit of snap,crackle and pop as it printed.
At 228C the surface finish was much better (much reduced s,n&p) but it was relatively easy to separate the vertical part of the bracket.
I tried 210C; the surface finish was really excellent but of course it delaminated instantly I took it off the bed.
I realise I ought to try drying out the filament (I used a new spool sealed in a bag with desiccant, but it might help I guess).
Has anyone printed parts (rather than RichRap's incredible vases etc.) with 618 and achieved toughness and a good surface finish?
