Latest Test Run. PLA on left. Bridge Nylon in middle. And IGUS iglide Tribo filament on the right using a .3mm adjusted STL file to print at the correct tolerances.
250-260 nozzle Temp. 110 bed Temp.
Any update here? Durability? Printing accuracy issues? The J260 has been recommended for carbon fiber rods that several seems to be implementing on their hypercubes eg. Would be interested if you have any particular feedback on that filament and your use of it :)
Printing accuracy issues?
The only thing to keep in mind with any of the IGUS filaments is that the 3mm versions are not the standard 2.85 or whatever standard undersize. Instead they are about 3.1 or 3.2mm and this means that all of yur prints will be way overextruded unless you either change your advanced settings in CURA or whatever software you use or modify your CAD files accordingly.
"Printing accuracy issues?"
Clumsy worded, my bad. What I was thinking about was if it was difficult printing a snug fit? Read so much about Igus bushings and their "micrometer-press to fit", printing them yourself sort of seems like the compete opposite. ;)
Any wear and tear to speak of then?
actually i have heard of other people having good success with these in PLA. PLA actually does not seem like it would wear too much. And even if they did its cheap and easy to print some spares
Well to be honest i had what i thought were good prints with plenty of slack and slid smoothly but when i actually went to put them in they had lots of friction and drag, so maybe the design pattern itself is a Press-to-fit geometry and what i really needed was more of a loose fit for a functional piece.
Just request your own free sample and experiment on your own. i can only tell you so much. I think in theory you could print just as good as commercial ones, i just haven't fine tuned mine yet.
My only comments on the yellow J260 Filaments are what i had said about it before. I did not like this yellow one as i had lots of trouble with it as it would not stick together very well and was like printing with playdough or baking soda. I only ever got one good print with it, and that was not in this round bearing style, only the flat 8020 extruded aluminum bearing style and only one of those. Multiple failed prints repeatedly. Not a filament i would ever reccomend or buy myself.
But hey, i think Igus still sends out filament samples for free, so request your own sample and try it out for yourself. As for me i really like the white I180. I bought a roll of the 3mm version of it on Amazon. My printer is currently down at the moment, but i really like that filament.
What bed and hot end temps did you print with the igus filament? And what speed?
The original Iglidur I180-PF free sample instructions gave a recommended settings at 250-260C and a print bed of 90-110C. I think i originally chose 260 and 110 and they worked well.
The new instructions recommend 220-250C and no bed temp suggestion.
For comparison the J260 recommended 260-290. I did not like this yellow one as i had lots of trouble with it.
Let me know if you'd like me to track down either the igus free sample link and/or the amazon roll i bought.
I think i printed at normal lulzbot cura speed and it worked good. I think i did try a few at high speed and they came out okay too. not sure.
nice. but the obvious question is do they actually work? If so, how do they compare to the regular cheap lm8uu bearings?
Thats a good question. Tom S. on youtube has a video about igus bushings and how they are really designed to be press fit and how thats generally not possible with 3d printers, but that they kinda work anyway. Although i think he has mentioned he actually likes lm8uu ball bearing bearing better. I dont know if these would work press fit or not.
But back to your question. Yes they do seem to work. I'm just barely starting to replace all my bearings on my printer with these. I dont exactly know if the pla or nylon ones work well but they seem like they would and i've heard reports that there are some people out there usong pla bushings just fine. Not sure if they are using grease or not.
I found the white I180 tribo filament to be excellent in this print and have one already on the printer and i think it has dramatically less drag and noise compared to the cheap chinese lm8uu's on there currently. I just ordered a spool of 3mm I180 tribo filament from Amazon yesterday and plan to replace the rest within a few weeks.
But i reccomend going to igus website and requesting a free sample of the tribo filament to try. That should let you know! Or if you decide to try pla the HTPLA might work better. Not sure.
