Good news, I was inspired by daniel and Cain, so i went out on a limb and bought some nylon trimmer string. think it was 15 dollars for 200 feet. But anyways here is the results, print time for 3 steering blocks was 45 min. Settings are shown in the screenshots. The only thing that is not the same is the steering blocks were printed with a prime and suck of 1.25mm. I increased it to 2.5mm to see if that will help with the stringing. Thanks for the inspiration. FYI the screenshots are some props I am playing around with for my tricopter while my HK order comes in. Though i would print them in nylon and see how they hold up.
how easy is it to do you make it seem easy anyways?
I have been looking at taulmans 618 for a while now and didn’t want to drop that much money on something that I couldn’t use. But after I saw Cain was printing with it. Figured it couldn’t be that hard. I was more worried about the bed prep and what to print on. From what I have read nylon sticks food to fiberous bed material. I went to the local hardware store looking for masonite but didn’t find any and didn’t want to ask anyone because didn’t think it was that important. The only filament I could find that was close to 3mm was ugly line which is triangle. But I figured if it didn’t work I could use it on my trimmer. When I got home I thought about printing on blue painters tape but unwanted to use the heated bed so that was a no go since the adhesive on the tape lets loose when heated. So I thought lets try the settings I use for abs which is heated bed at 120C and glass sprayed with a nice layer of harispray and allowed to dry. Works fast on a heated bed. Then smear elmers purple glue stick on it and allowed to dry. I was kind of worried about the ptfe tube on my head leaking nylon because the filament was small and was a triangle but that hasn’t yet. Calibrated by printing a hollow box on kisslicer single wall with the measured diameter of the filament. Then I took the number which I had set for the ext thickness to be and divided it by what it actually printed. The setting in kisslicer was .7 and what it had actually extruded was 1.0mm. So I took .7/1 which was .7 . I took this number and put it in as my flow and resliced. Box printed out with wall thickness of .71 . Close enough for me. I have found that unlike abs, the nylon take all of the glue up and has to be reapplied, if not it warps really bad where there is no glue. Hope this helps. Btw just ordered some 4lbs of trimmer line for 25usd shipped . Let you know how it works. Hopefully its solid and doesn’t have a core. But its manufactured by desert extrusions which from what I understand it is just nylon. I’ll keep in touch
Wow cool what computer program you running sir and what are the software requirements?
It’s kisslicer, Located at http://kisslicer.com/, not sure about the requirements but I am running it on a 7 year old celeron laptop. Runs fine. Hope this helps
i have found the gears i printed with the trimmer line have held up better than the ones i printed with 618, and they seemed to print nicer too…
Yeah well see I printed the rear and front diff plate earlier today and some new herring bone gears for my extruder. Good thing I did because my extruder fell apart today. Printed it before I knew about calibration and was learning skiemforge. But the nylon herring bone gears on the extruder are nice and smooth. Hope to get a long life out of them.
how did they go? i have found that the only diff i haven’t had gears get destroyed very quickly is the gears i printed with the whipper snipper line, (the 618 Nylon didnt last any longer than the ABS, im now printing all the gears with the snipper line), infact they show almost zero signs of wear and i have rebuilt the other diffs about 4 times each, i also dont have the rings on the axle shafts on the diff and they havent broken.
AND it prints much easier, zero stringing compared to the 618. it prints as good as ABS.
I get a little stringing at 3.5mm retract but nothing to complain about. bought two rolls supertrim line off amazon for 8 dollars for 2lbs. Put them on spools today , but haven’t gotten a chance to print with them yet. Cain what nozzle are you using? I have a jhead with a .5mm nozzle and have not had any problems, but was thinking about getting an all metal nozzle so I can eventually print PC. I actually have a second set of rods, ramps board,nozzle, plastic kit and was thinking about putting together another i3. Not sure of the wife would like that though, 
i have a 0.35mm J-Head… and i will also be making a few all metal hot ends, a 0.25 a 0.35 a 0.4 and a 0.5
