is it a bad idea to use trimmer line as filament?

I brought one spool for my trimmer from amazon, but realized it maybe can also be used as filament for my reprap. [www.amazon.com]

The description says it's made from sturdy nylon. Do you think it will emit hazardous particles when being heated at 200C?

I found the idea on [reprap.org]
reprap ROCKS!

You can certainly try it. You might want to put it into a low temperature oven for a while to drive off moisture before you try to print with it- nylon absorbs a lot of water I wouldn't count on it having a consistent diameter- Be sure to measure it at multiple places along several meters of filament and calculate the average diameter and use that when slicing or when printing if you sliced for volumetric extrusion.

Read the reviews on Amazon for the size just below 1.75mm. I bet that quarter of them are from people using the thinner stuff as printer filament.....

I used 2.9mm trimmer line, and it worked ok-ish. I needed to dry it well in the oven prior to printing, if you don't get it completely dry it starts spitting steam and throwing nylon everywhere (I live in a very low humidity climate, so even more important if you don't). I was printing at 270C, you'll need an all-metal hot end (I've got an E3D V5) or you'll start melting things. Results were OK, but not great, it tended to warp/lift much more than either ABS or PLA, and getting good bed adhesion was tough (painters tape at 60C was the best I found). Worth a try though, I got 20m of nylon for a few dollars.
