One of the weak spots just got a whole lot stronger printed in Nylon!
Hello Daniel! Can i ask you some question about nylon filament you use?
@Ivan_Dampir Of course you can!
What is the melting point, and weight of spool? I have “Up! Plus” (Afinia) 3d printer, and want to know, how suitable is it for printing with such material, concidered the conditions of temperature 180 for PLA plastic and 270 for ABS…
@Ivan_Dampir According to Taulman3D´s website the melting point is 218°C (i print at 238°C)
1 spool of 618 Nylon which i use weighs about 0,5 kg (1pound).
Where did you get those temperature specs? Don´t try to print ABS at 270°C it´s way to hot! I print ABS at 220-230°C
I can’t manually change the print temperature in “Up! Plus” printer because of software. It lets to use just two modes of temperature: 180 for PLA plastic and 270 for ABS. May be it somehow change temperature in the process of printing, but i don’t sure. However, thank you for information!
I usually print at 242C for Nylon. Anything lower for me results in delamination. @Daniel_Noree , if you end up having parts split along the build axis, bump up the temp. Nylon is nearly indestructible.
What is the best surface to print the nylon on?
@ThantiK ok, thanks for the tip.
@Sonex128 I have not succeeded printing on anything else then Garolite.
Same for me Brian : 245° and Garolite G11 
i just had some good results with brush cutter line, and Masonite as the bed. although i think i have some size issues as the diff shafts are about 0.3mm to big to fit the bearings, but man is it tough!!
Cain what was the diameter and brand of the line. I was at the depot center the other day and was looking at them but i would have to change my hotend setup because i am only using 3mm filament atm. Just that it would be a quick and easy test since i wouldn’t have to wait for it. Also what is your setup for temps and bed type?
Daniel sounds like you found something to take abuse of your reckless driving. 
@Lawrence_LaRocque mine was 1.6mm and it was the cheapest stuff i could find, i cant remember the brand, just make sure it doesn’t have an obvious core (they are normally a different colour) you can get 3mm thick line also. i printed at 245°C onto a Masonite (hard board) bed heated to 90°C
I will definitely look into that. I do not have to worry about fumes and such because the printer is in the shop. I might pick some up on the way home today. Sounds like good times. Working on trying to get the parts for the openrc right now. Slowly because my son and I working on tricopters right now. Had to rebuild it several times because getting stuck in trees and crashing into playhouses :P. But on a good note the body and motor mounts that i printed have not broken yet
you wont regret the nylon its damn strong (but quite flexible)
@Cain_Blank I am assuming since it is MDF that you did not have a heated bed and printed directly to a scratched surface of it. How thick is the board?
not MDF Masonite and i used the smooth surface, and a heated bed to 90°C (it will tear out a small layer when you pull the part though)
I read one thing and posted another. I have been reading everywhere about bed surfaces for thing and I didn’t go back and re read your post and just assumed. What was the thickness, I have only used it for pouring concrete curbs, but I am going to look at it today.
Picked up some trimmer string. Well see how it goes. 
Just started printing. Didnt really change any settings from my ABS settings other then i made the hot end temp higher. Printing great so far, no warping as of yet, in about 50 min so far. Only thing I see now is that i need to increase the retraction distance because it is string a little bit. Will post when done printing. Went with 3 perimiter, .55 ext width, and 25% infill. well see
