How do I print Taulman Nylon 618 ?
They did get back to me from Taulman and they said: so in all fairness I post it in this thread note long drying time at a lower temperature than I expected I was using 160 for just a few hours.
Tom here.... 618 prints at 255C for a std .4 nozzle. Max speed is 40mm/s Use a glue stick on the bed and heat to 80C.
Our Nylon 230 is very close to Nylon 618.
Dry 618 at 120F for 24hrs
Thanks Tom
This is the only info on 618 that I could find
from their website: Taulman Nylon 618
618 was the first nylon specifically formulated and processed for 3D Printing.
Technically, nylon 618 is an extremely high quality variety of nylon 6,6. Only one chemical company manufactures this specific variation of nylon. Both the chemical composition and post processing developed by taulman3D work together to lower the print temperature of high quality nylon as well as reduce the non-uniformity that nylons exhibit in the melted state.
618 is a pure white polymer and fully capable of absorbing acid based dyes. 618 printed with 100% fill rivals it's injection molded equivalents in strength. All of the feature of nylon that we come to depend on are at the maximum in 618. Slippery surfaces, pliability, strength, non-scrape, chemical resistance and high thermal durability.
END blurb from the Taulman site:
I was chatting to a friend and he gave me a couple of one pound spools of Taulman 618.
One had been opened and perhaps 100 feet used the other was still sealed in its bag but the bag has lost its vacuum those spools are now in my forced air filament dryer at 160f.
He told me he could never get it to work on his rep-rap Mendel about 4 years ago and had given up on it.(and on 3d printing in general ).
Well I know it has to be dry, does anyone have any Slic3r-PR settings for it? the label on the spool does not even have any temperature recommendations
I assume that the reason info on it is so slim, is that Taulman no longer make it; but I would love a starting point for my settings… I do print some brands of PETG at 235 but I think I was told early Nylon filament had to print at 285 for the first layers… Is it ok to use on the Prusa powder coated steel sheet or must I source a glass bed to use it?
thank you for any pointers you can provide I had NO response asking Taulman this question via email. so any help gladly received
Re: How do I print Taulman Nylon 618 ?
I printed lots of Taulman nylon on my Printrbot (although mostly the 645 variety). I've discarded all the old G-code files since moving to the Prusa, but if I recall correctly I used 235C for the extruder and 70C for the bed.
I was printing on glass coated with Scotch Craft Stick, and I'm 99% sure that it will print on just about any heated surface if you coat it with glue stick. If Scotch Craft Stick doesn't give you enough adhesion, try Elmer's Washable School Glue (which goes on purple but dries clear) - it actually caused too much adhesion for me when used on a glass bed.
Nylon is extraordinarily tough, a great material for mechanical parts that won't be exposed to extremes of humidity (or liquid water). See this post: http://www.printrbottalk.com/forum/viewtopic.php?f=74&t=5286&p=34509
The downside: when printed nylon absorbs water, it tends to warp and can even delaminate.

Just a suggestion - have you tried the Taulman bridge preset in slic3r

Re: How do I print Taulman Nylon 618 ?
Not yet it is still in the dryer and I have to find a way to keep it dry while I print a 5 hour mechanical part... But it is worth a try...I will try all the Taulman Nylon settings I can find as my todo list.... I don't know if I should risk My Prusa powder coated steel sheet or to cover the sticker smooth spring steel sheet with purple glue stick...i would hate to wreck them when they are so hard to replace. To do it over this gifted Nylon 618 would be foolish.
The stuff I am finding about Nylon says you have to print on glue covered glass and as I do have a glass bed printer in my big Delta Rostock Max I could try it over there but right now that printer is disassembled pending a major rebuilding later this winter after the holidays it is a SeeMeCNC V2.5 kit and I will take it to a V3.3+ Duet level when it is done
Would be nice if I could get the facts on one of the early Nylon printable filaments

Thanks. I will give that a try.

I did at last get a response from Taulman on the 618:

Re: How do I print Taulman Nylon 618 ?
If you live in the northern hemisphere, your ambient humidity indoors is likely to be fairly dry. In my experience printing dozens of spools of nylon, it doesn't absorb humidity from the air anywhere near as fast as TPU does. I could safely put a dry spool in my ambient winter air for 24 - 48 hours before needing to dry it again.
The nylon will mainly interface with the glue, not the bed, so I don't think it matters whether the substrate is glass or PEI or whatever...
Re: How do I print Taulman Nylon 618 ?
Weirdly, I also just came into possession of come old Taulman 618 in a punctured original packaging - so I'm really interested to hear how this goes for you. Please post pictures!
Re: How do I print Taulman Nylon 618 ?
I would love to know why they stopped making 618 and replaced it with Nylon 230
Please see my next post about Polyalchemy Elixir PLA which I how I wish all filament makers would document their products
RE: How do I print Taulman Nylon 618 ?
This is six years after the last post, but a funny thing happened. I found two spools of Taulman Nylon 618 in my filament box. These go back to my first 3D printer, a Thing-o-Matic. They must have absorbed a lot of water because the sides of the spools were bowed out. After 12 hours in the dryer, the sides are more nearly parallel. After another day or two, I will try printing with them in my Prusa-XL.
Thanks for the suggested temperatures and feeds. I'll see if I can bend PrusaSlicer to my will.
