jittery inner wall

Recommended Posts

Hi folks.

I have noticed that my printer often does this strange thing where it "vibrates" around the inner wall. this is more time consuming that simply tracing around the edge as i would expect it to do. ive taken a look at the slices and think that the images reveal why its doing it.

the first one has a nice clean inner trace and the second one is all mudded up. does anyone know why this is happening?

Any help would be much appreciated.

Dan

Hi,

Please give us the profile you use by saving it in ".ini." file.

Then, we would be able to open it and check it out !

 

hi this is the copied text from the .ini file. is this what you require?

thanks.

ps. i noticed that the inner line clears up when i revert back to a single instance of the model(the screen shot was taken when there were two copies )

whether this will translate onto the print ive yet to find out but whatever the result its strange....

I believe this is caused by the top/bottom thickness. If you set it to 0, you will notice this goes away. (but obviously that's not really an option unless you want an open top, but try to slice it with that setting to 0 to see if it's what's affecting it).

There is a reason for this though, it places material under the next layer's inner perimeter. While annoying, it serves quite an important function IMO. On larger details it will be lines which makes sense, but if you have a gradually sloping side, it will appear to 'vibrate' because the lines are small.

Anywho, that's what I think it is, and if your object looks good it's working as intended. :D

*edit, I just had another thought after I posted... It could also be that your object has way too many polygons.

I am using ABS yes.

valcrow - I tried on your suggestion to turn off the top/ bottom thickness but this did not help. I have also tried reducing the polygon count to see if that helps. It didn't. Ive included a screenshot of my object in wireframe mode. The troublesome areas seem to be the fingers which seem to have a cleaner mesh but they are square polygons. could this be the problem?

Also included more cura screenshots.

Thanks.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
