Printing with Nylon

[jimc]

davo, sandpaper on the plate is a new one. thats interesting. what kind of grit are we talking? 320-400grit? coarser.....finer?


to the op, nylon can be tricky for larger prints. it does shrink alot so it loves to warp. currently i use garolite as recommended by taulman. so far its been hit or mis. onle time it will bond so hard that the garolite come off with the nylon and i can print the same part again right after with the same settings and it will be peeling off the bed like i waxed it. as for the settings i run pretty much what davo said. the only thing that is odd with nylon is you usually need retraction and ooze control settings that are a bit on the extreme side. i think i am at about 3.5mm for retraction and 2-3mm of coasting along with a slight negative restart distance. i can get my prints to come out super clean if i can get them to stay stuck consistently.

jimc..... I think I will try Davo's sandpaper trick first as I have heard it is pretty much hit or miss with garolite plate. I think I can get 220 grit sandpaper with peel & stick adhesive on the back and lay on my glass plate. It's sounds like a great idea to try.

I noticed Taulman recommended a higher 245° C extruder temperature for nylon 618. I thought nylon has a higher melting point than ABS. Since posting, I found this on Taulman site

And this on Thingiverse site

Are we talking about a different type of nylon? ..maybe nylon 645? Have you tried that setting with success or is that not a good idea?

Also, thank you for your advice on the retraction settings.
