Taulman 618 Input
August 13, 2015 11:24AM
I tried printing with Taulman 618 nylon for the first time last night. I was hoping to get some input to improve my print quality. I printed on heated glass with elmer's purple glue stick at 55C. My extrusion temperature was 245C and I was printing at a pretty slow speed. The large cone print is at 100% per customer request and I feel that is probably one of the main reasons I am seeing uniform warping on the bottom of the entire part. I dried the filament in an oven for 2 hours at 170 F just before printing. I measured the filament to get correct diameter before slicing and I am using a makeshift enclosure to prevent any drafts.The green part is ABS for comparison.

I'm not sure about nylon temps but 55c seems way to cool.

55c is what Taulman recommends.

The settings you are using are spot on what the manufacture suggested.

But they also suggest 100% pva instead of gluestick. What I'm using is a watered down solution of elmers glue. Spread on the bed with a foam brush and allow it to dry completely before turning on the bed.

However, painters tape tends to peel and I suspect that is causing my warping. I'm going to try the PVA on top of hair spray applied glass.

Also, the speed on the print is a factor. I'm printing at a slow pace of 25mm/s (also suggested by Taulman) (yes, its painful to watch my printer go so slowly)

If you can find this stuff, they say it works wonders for nylon

1/4" sheet of Garolite LE (as seen here: [www.thingiverse.com]).

I almost purchased a sheet from mcmaster. Work used to have bakelite and I was hoping to snag a peice to try out at home since its the same thing. I also heard that canvas works really well when it is epoxied down to a glass sheet. I thought the bumps on the outer edge where moisture in the filament. I tried printing the same piece in ABS and got the bumbs again. A buddy told me it was over extrusion and as usual he was right.

I am still getting lots of warping but at least these parts are coming out tough as nails. The layer adhesion is really impressive. I wish I could find more information on others printing attempts with nylon.
