Hello, i have this issue which i never was able to readuce 100%, its like near the end of an inflill line, it pushes a bit of excess material to a side from the previous line, reducing extrusion multiplier does not seem to be the right fix, since it also causes small gaps between infill lines. Im using a 0.5mm nozzle, near 70mm/s top speed, slicing with simplify3d [attachment 108006 IMG_20181111_170437.jpg] [attachment 108007 IMG_20181111_170429.jpg] https://reprap.org/forum/read.php?262,838528,838528#msg-838528 Tue, 17 Mar 2026 07:56:28 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,838528,839224#msg-839224 https://reprap.org/forum/read.php?262,838528,839224#msg-839224 I'll give it a try]]> luismanson Printing Wed, 21 Nov 2018 14:06:50 -0500 https://reprap.org/forum/read.php?262,838528,839195#msg-839195 https://reprap.org/forum/read.php?262,838528,839195#msg-839195 infill and perimeter do overlap - that is exactly at the ends of every infill line.]]> Dancer Printing Wed, 21 Nov 2018 09:37:07 -0500 https://reprap.org/forum/read.php?262,838528,839186#msg-839186 https://reprap.org/forum/read.php?262,838528,839186#msg-839186
I was able to perform just a single test, but reducing speed did improve a lot the final quality, there are still room for improvement.]]> luismanson Printing Wed, 21 Nov 2018 08:24:19 -0500 https://reprap.org/forum/read.php?262,838528,839176#msg-839176 https://reprap.org/forum/read.php?262,838528,839176#msg-839176
@dlc60: strange. I used a spool of white PLA filament a while ago - was no different to the other colors (I nearly only use PLA, only very seldom PETG/TPU/PA6.66)]]> Dancer Printing Wed, 21 Nov 2018 05:07:47 -0500 https://reprap.org/forum/read.php?262,838528,838978#msg-838978 https://reprap.org/forum/read.php?262,838528,838978#msg-838978
I notice that you're using white filament. I have used three different, good quality manufacturers' filament and whenever I use a white filament my surfaces look like crap. Swap out the white for another color and all is perfect...

Has anyone else ever noticed that white PLA prints poorly? What is the secret for printing white PLA?

Thanks,

It's basically due to nozzle pressure not being able to adjust rapidly enough to account for slowing down due to direction changes and how fast it can do 180 degrees turns, which is what solid infill is. So to fix this you can try making the nozzle spend as little time doing cornering, at as close to the speed you're doing infill.

To a lesser degree the way the bed is mechanically mounted can also play a role. When mounted on springs, any back and forth motion will dip and rise the bed slightly and bounce as you can see in the extrusion lines. Replacing the springs by shims will help to some extend. The i3 mechanics aren't really good for higher speeds than 40mm/s tops.

As mentioned, the new default setting for infill overlap is 25%. It used to be 15%. When I dropped down to 15% it improved a lot though some gaps may start appearing if there's too much compliance/backlash. Even without compliance gaps may appear.

At higher speeds filament tends to cut corners too, so the too of 'hearpin' corners may draw together, bunching them up.

The bigger the nozzle the higher the tendency to ooze and leak. Try 0.4mm nozzle and see if that improves it.]]> imqqmi Printing Thu, 15 Nov 2018 17:31:22 -0500 https://reprap.org/forum/read.php?262,838528,838639#msg-838639 https://reprap.org/forum/read.php?262,838528,838639#msg-838639 stop nozzle rising on direction change.]]> MechaBits Printing Thu, 15 Nov 2018 16:16:36 -0500 https://reprap.org/forum/read.php?262,838528,838535#msg-838535 https://reprap.org/forum/read.php?262,838528,838535#msg-838535 luismanson Printing Wed, 14 Nov 2018 10:29:23 -0500 https://reprap.org/forum/read.php?262,838528,838533#msg-838533 https://reprap.org/forum/read.php?262,838528,838533#msg-838533
