Printing Nylon Trimmer Line

I'm getting setup to print this nylon trimmer line:. I 'm waiting for the rest of the parts I need to convert my hotend to 1.75mm. A user on seemecnc got in touch with the manufacturer and was told that the line is made from virgin nylon 6.

In the meantime I've been doing research regarding hotend and bed temperatures, the best way to get adhesion and any other printing tips and am finding lots of conflcting information.

From what I've seen hotend temp is recommended anywhere in the range between 240c and 260c, but bed temp varies anywhere from a cold bed to 40c, 60c, and even 105c. Has a consensus ever been reached on what the best temperature is? I plan on printing on glass or cardboard with UHU glue sticks to promote adhesion. I've seen people printing at lower bed temperatures with this method. Are there any other benefits from printing at the higher temperatures?

The biggest difference of opinion and experiences I've seen is with warping however. Some people claim that nylon doesn't warp while others have experienced major warping, even enough to crack a glass print bed. Will the trimmer line not warp if I manage to get good adhesion to the bed?

I will try fresh trimmer nylon and also dried out amounts. I just need to devise a cheap way to keep it dry. I plan on posting the results I get as soon as I am up and running.

$22 for about 4lbs? I would be highly interested in finding out how you get this to work well, if you do.

Taulman tested dozens of different nylon variations, you get a huge variation in between types.
I wouldn't bet on the trimmerline to be printable at all in the end.
You can expect problems with shrinkage, warp, layer adhesion, adhesion to printbed, odor/fumes ....
Keep in mind that for the main purpose of the trimmerline it makes no big difference what exact composition the Nylon has. They can use lower grade stuff without any problems and they don't care much what fumes come of it if you melt it.
I wish you good luck, but personally i would never use that stuff for health reasons alone.

I have used the Red version of this stuff. Same seller, same product, just a different color.

It works amazingly well but you have to bake it at 175F for about 3-4 hours to get all of the moisture out. It has a really nice surface finish to it that is very shiny and smooth.

When your not using it I would highly suggest putting it in a sealed container with desiccant packets to make sure that it doesn't absorb moisture again.

If you run it you will get a little bit of steam coming out of your nozzle and on my Ultimaker Original I had to run it at 235 and 60ish mm/s with a 135 flow rate. I made a few of the antivibration feet and they work great. If you make a stretchlet it will stretch beyond belief. Its some great stuff you just have to remember to bake it first and keep it sealed so it doesn't absorb water again. If you start to see alot of steam coming out of your nozzle then it needs to be baked again to get rid of moisture. The water effects print quality alot.

So I emailed the company who produces the maxpower trimmer line:

I was told that there are small amounts of "processing aid" additives in this specific nylon trimmer line. Also I inquired if they take any precautions in extruding the trimmer line. Apparently the only precaution they take is to ventilate the area.
