Hi guys,
I need help from you guys, I’m making keychains sign of the horns, the idea I got from here: http://www.thingiverse.com/thing:9541. On photo red striped bottom to top are twisting in the index finger, printed with a layer of 0.2 mm height, solid infill every 1 layer, without the buffer material, using Slic3r, and the best results than others.
I’m guessing the material (PLA?) is not getting a chance to cool, since it’s past the pinkie height, so the nozzle is dragging it around.
I’ve had best luck solving this by printing multiple of the object. That way, each gets a chance to cool as the other is printed.
+1for cooling issue
You can also try to lower temperature at this height (Cura has a plugin to change such things on a pecific layer), or add cooling fan to the nozzle.
Slicer has a setting that slows down for small cross sections, but @Carlton_Dodd has the right idea, build other objects poor a cooling pillar, this will prevent dripping. You should definitely use a fan if you don’t already have one, as also mentioned. Prints come out much better in PLA. Good luck
I personally fight this issue by printing multiple copies. This kind of prints are troublesome with all kind of filaments.
Slow down the print, when it hits the top of the finger it lays the next layer before it drys. There is an option in Slic3r where you can set the min layer time/speed. But all you need to do is slow it down, practice on the 5mm calibration cube.
@Ralph_Apgar I’ve tried slowing the print down, but it made it worse for me. The problem is that the nozzle stays in contact and conducts heat to the small layer, keeping it soft. The nozzle on my PrintrBot Simple has a fairly large flat area, making the effect even worse.
cura has a cooling setting where if it doesnt meet the time requirement the head will move to the side and wait before moving back in for the next layer. @Daid_Braam could probably fill you in better (pun intended) fill in… ah never mind… tough crowd

@D_Rob , if I have the print had move away too cool using PLA, my nozzle drips like a runny nose. I’m looking forward to trying my new e3d to see the improvement, but the priming pillar worked for my cruddy knockoff j head hot end.
Thank you guys, I do use the PLA to make it, from which you have to say, if the solution to this is to perform multiply. What if the skirt height is to make it as high as the model, you ever tried this?
Currently I still change the model so that there is no material support, while looking for a solution with all of you.
@Heri_Suprapto Making the skirt height the same as the model should work, but would likely take as much aplastic as printing a second one of these models.
I think slicer has a setting for priming pillar… our maybe that’s kiss, haven’t used my printer in a while since it broke, only been using the Makerbot at work
Try printing a small pillar at the same time. It would act as a way to cool and a place to wipe the ooze away
I agree that a lot of plastic that has been used for it, the result is: https://www.facebook.com/photo.php?fbid=614665115282263&set=a.389166764498767.88676.100002163400628&type=3&theater , from the above conversation and I do perimiters small reduction in speed to 20 mm / s and add a skirt as high as alternative models for the temporary replacement of multiply. I think the results are pretty good.
@D_Rob This what you mean: https://www.facebook.com/photo.php?fbid=614665811948860&set=a.389166764498767.88676.100002163400628&type=3&theater , with another setting, maybe I will try the same setup with the photo using the skirt above.
