  1. Hi, now I have finally tried the bridge also. For me the filament is 2.85mm, if you also have that diameter you should change the diameter setting in the printer or it will not extrude enough material. Make sure the nozzle is very close to the surface.. I usually adjust the height on the fly while it is printing the brim. The lines on the brim should flow into each other..

    Bridge is the best nylon I have tried yet. I have only tried small prints, but I can use glue stick on glass! It appears to be sticking a little better and also warps less, like it says on the Taulman webpage. I use a 5 line brim and 40 degree buildplate. 247 degree nozzle.

     

  2. Thanks for the replies, good to know that there are no hidden differences, just that the nozzle size is not a flow rate adjuster, should have figured that one out.

    I´m experimenting with getting better layer bonding with nylon, increasing the flow rate with 10% helps a little..

    Interesting how Cura handles different wall thicknesses. If I decrease the nozzle with 10% ( to 0,36mm) and increase the flowrate with 10% and keep the wall thickness a multiplier of 0,36, I should be able to get the layers to extrude into each other and bond a little more.. worth a try :)

     

  3. Hi,

    Are there any differences between these settings?

    In the Ultimaker 2:

    Flow - in customize material

    (Filament) Diameter - in customize material

    Material flow - when printing

    In Cura:

    Nozzle size - in advanced settings

    It seems all these settings control how much material the extruder will feed at any given speed, so if I want to increase the flowrate, they would give me the same result?

     

  4. I've tried taulman 645 now, and it is definitely more difficult to print with than 618 for me. When printing the bracelet for example, it works fine, but with parts that have lots of retraction it is under-extruding. Maybe it sticks more to the bowden tube or something. It is more translucent compared to 618, and at higher temps it seems to "crystallise".. currently using 245 degrees, 2,5mm retraction, 3,05mm nozzle setting, 0,2mm layers.

    Edit: The layer bonding seems to be better, and it's less brittle I think.

  5. Seems like a really low temperature for nylon? I've only tried taulman at 245 minimum and I have basically no stringing.. I printed at 260 today and I ran out of filament, so I just fed some more in while the machine was running. Now I got some stringing since the retraction was not working well, but decreasing the temp to 245 almost removed all stringing, despite retraction not being able to function well..

  6. Today I tried 100mm/s, 0,2mm layers, 260°, no fan and that worked ok. The quality is a little worse. Bonding is better with no fan. Possibly due to higher temp also, have to do some tests on what settings will decrease delamination. I tried putting the diameter to 2.95, because I read that over extruding material would help with bonding, but that covered the nozzle tip in nylon :)

  7. I've also printed Taulman 618 on UM2, works really well I think. Maybe I was lucky with the bowden ID, but I get no sticking. I used the standard PLA-profile and changed temp to 245, dimension to 3mm and buildplate 40 degrees. First I tried glue with the glass plate. I got some slight warping on the UM-robot.

    Now I have switched to an art canvas (some sort of textile on a masonite) which works great, I get no warping. (Build plate of course changed to 0 degrees)
