If you buy Taulman's Nylon 230, then you can print Nylon at 230°C on a stock printer. It's only $25 per Kg on Amazon. It's also great for making gears, bushing, orings, and gaskets because its self lubricating. I got it and it prints beautifully. It has a hard time sticking to the bed, so I use liquid white elemers glue. I like to mix about 15% water and 85% glue together to make it easier to spread. Heat the bed up, apply glue in a zig zag pattern, then spread evenly on the bed with your finger in circular motions. When it starts to dry and get tacky, which it does pretty quick, I press my finger print up and down everywhere in order to make lots of little ridges to increase the surface area for the nylon to stick to.

One last major thing. Nylon is EXTREMELY hygroscopic. Meaning it will suck water right out of the air. I left the roll out on a semi humid day for about 18 hours. I didn't put it away because I was going to use it in 18 hours. The next time I printed it was snap crackling and popping because the moisture it absorbed was turning into steam when it hit the 230°C nozzle. I put it in a gallon sized zip lock freezer bag (you must use a freezer bag because the normal kind is not air tight) with a bunch of silica gel packs for a few days and that resolved the problem. You can buy a 50 pack of 5g bags on Amazon for $11. I use 5 of them in the freezer bag.

This is the one I got. There are ones out there that are $45 per kg, and one that's $24, but it's only 1 pound. This one printed great for me and the diameter was spot on.
