Intense Ghosting and Stringing

Recommended Posts

I've been printing quite a bit recently, and I'm beggining to notice some ghosting I just can't get rid of. The most recent model I've printed is a little model I sketched up of a UFO crashing into the ground. I've printed it twice now, changing the settings a bit after the first one failed, but if anything the second print looks worse.


Some intense stringing on the second model I printed.


The model on the right is the first one I printed. It was printed at 205 degrees, at 50mm/s, and with 0.1mm layers. Retractions were 50mm/s and retracted 4.5mm. Travel speed was 250mm. I used 3000mm/s acceleration.

The model on the left is the second print. I printed at 210 degrees, at 20mm/s, and with 0.05mm layers. All retraction/travel settings were left the same. This time, though, I used 1500mm/s acceleration.

I'm really confused as to what's going on here. I had been printing fine until last week when the problems started coming up.

For the second one you increased the temp made it slower and lowered the layer height. All of these changes allow Pla to get really hot and will increase Stringing.

To remove ghosting you normally just reduce the acceleration a bit. Reducing it to much can cause over extruding on direction changes. So try 2200mm/s.

Stringing you want to go colder, so to do this you normally reduce the temp.

If you reduce the layer height then the flow of the plastic is slower so you need to reduce the temp again. This also goes if you reduce the print speed.

Yikes.  About halfway through the print now, with all the settings listed above:


Some crazy layering issues.

Any ideas on what I should change?  I used the LCD monitor to turn the heat up by 5 degrees so it's now at 200C.

UPDATE: I had to stop the print. It wasn't getting any better.
