3D printers can't extrude filament properly
Users are experiencing issues with their 3D printers, including inconsistent extrusion, stringing, and texture problems. These issues often arise when switching filaments or after printer upgrades, leading to failed prints and frustration.

“Hi all, I've been trying to print lithophanes, but i am running into this issue at specific regions. It looks somewhat like underextrusions or something even though I recently calibrated my extrusion multiplier and it looks good everywhere else. I even tried to print only…”
“I'd "love" it if someone had an idea of what I’m doing wrong here... ;) The thin-walled heart shell that I’m printing goes bad at the outer (slightly thicker) edges of the print, about where the “internal infill” starts getting replaced with “Solid Infill” near the edges of the shell as the shell goes upward (referencing the PrusaSlicer’s internal view) (See also the slicer movie here ( https://youtu.be/C2ZHjdbNaKc)). The shell is actually thicker on the sides, which is why the ext”
“Hi everyone, I’m hoping someone can help me solve a recurring print-quality problem. Whenever I print parts with many small holes like the one in the photo, the top surface comes out very rough and messy. There seems to be excess/uneven material around the holes, and some of the holes look partially obstructed or poorly formed. submitted by /u/Xafniko [link] [comments]”
“recently I tried to print a paint rack. halfway through, the printer decided it wanted to make a tennis ball sized blob instead. every time I try to print something now, it seems to leak filament from the base of the nozzle (as seen in video). just wanted to know if this is a common issue or if there is an easy fix for it. any help would be greatly appreciated. printer is an elegoo neptune 4, just using standard black PLA, temps between 180° and 220°. problem only occurs when printing anything,”
“Hello! I am trying to get the printer to stop doing this, it’s a raised texture compared to the other parts. Sometimes globs of filament that are brown or darker than white get stuck in.

“I have an Ender V2. Regardless of how many times I re-level, dry filament, etc etc. I've even changed extruders twice now. My prints end up with some lines filling in and being smooth, while others look like a 3d rendition of polka dots.

“Every print that I make, any filament I use, it always has the same result. The bottom few layers are completely fine, then 5mm are complete trash and the rest of the print is again completely fine. The bed is leveled, the filament is dry, the printer is clean and stock, the nozzle is in top shape... Could this be like a spec of dust trapped somewhere on the Z axis? Should I take apart the printer and clean it properly? I own it for 3 years and this issue was there since I remember. It's an”
“I got multiple print and object’s on the same printer that all got this line at a certain Y value. It looks like the exterior wall that is under-extruded. Anyone else got this issue? If so, what is the fix? Edit: the first layer is atrocious but I adjusted the Z-offset after the first layer to get a good layer fill submitted by /u/ElouFou123 [link] [comments]”
“My A1 is severely under-extruding during prints. Manual extrusion works fine, but during printing the extruder sometimes makes a repeated “click click click” sound and the filament stops feeding properly. I did a cold pull, but it looked fairly clean. The problem seems to happen mainly under higher extrusion demand. What am i suoposed to do submitted by /u/Affectionate-Buy-711 [link] [comments]”

“Hello everyone, I have 2 Flashforge AD5M Pro printers with .6 nozzles. I am using Flashforge High Speed PLA and I have noticed that both my nozzles end up like this after every print.

“Hi folks, I'm new to flexibles and foaming filaments and would appreciate your expertise to help figure out what's going on with my print.

“I keep getting blobs forming on my print nozzle. I’m using PLA at 195 deg C. Printer is an Anycubic Kobra 2 Neo. Any ideas on why this is happening? I just replaced the nozzle, because the old one was clogged. It looks like filament is leaking around the top of the nozzle. Did I not screw the nozzle in tight enough? I’m pretty new to printing, I don’t know much beyond the basics. Troubleshooting is still a challenge. Thanks for the help. submitted by /u/SterlingArcher32 [link]”
“The print serves it's function perfectly well, so there is no reason to throw it away, but I would like to know what to do different next time. The filament is tpu 90a and the printer is a bambu p1s. The filament was fed directly into the printer as opposed to being fed through the ams. The filament was left out for a year (around 50% humidity.) before it was given to me (free roll). I dried it in my space pi drier at the appropriate setting for 12 hours before I used it. I'm sorry for d”

“On some prints, even on ones from the app that normally work, the extruder will click similarly to when it’s clogged and unable to push filament through (the wheel will click and move back and forth). But these times it will lay down a very sporadic first layer and then the second layer will be completely smooth. Anybody know what’s up? submitted by /u/Fickle-Lunch6377 [link] [comments]”

Before I started printing, I ran the drying cycle on the ACE for 2 hours. In the picture , you can see the smooth surface is interrupted by jagged peaks. The front right portion of the print is very smooth. The rest of the print is very rough. What could cause this? I thought it was a case of we”

“Hello reddit 3d people, I need help. Just got my first 3d printer, a used BIQU B2 to be exact and in the middle of my third print, it started doing the thing that happens in the video. I tried changing the filament and it does the same, does someone know what it could be? I think it wasn't the model I was printing because it was a two part print and the first one came out fine. For clarification, I'm using PLA and 200° on the extructor and 60° for the bed and my slicer is ORCA Slicer. Ma”
“Hi all! Looking for some guidance :). At certain angles the print shows these ugly lines, or maybe that's normal? At other light angles the ugly lines reduce a lot. I'm referring to what looks like an uneven texture of lines. I did temp, flow rate, pressure advance, and max flowrate calibrations. Should I give up and accept this as a normal print, or is there more I can do in the slicer? submitted by /u/Ok-Broccoli5316 [link] [comments]”
“Has anyone seen anything like this before? I ordered this .4 stainless nozzle from Amazon. It failed on the first print. Printer said it was complete, but it stopped halfway through the model. Couldn’t extrude anything out of it. Tried to clear the clog and normal methods weren’t working. I cranked it up to 280° C and this is what came out. No idea what this yellow substance is.

Also, very brittle, was like that fresh from airtight bag. I can toss it in the bin.

Seems to get jammed in the extruder but the weird part is if I feed the filament by hand it passes through fine, so does the clog puller, but if it tries to load through the ifs it can’t pass through. I’ve adjusted the tension screw multiple times, and nothing seems to fix it. Confirmed there was no issues in the tube itself. I replaced the black box thing (idk name) and this one does it too s”

Issue continues - after some time filament extrusion stops but the print (i.e. toolhead movement) continues.

They are supposed to be perfect circles yet they’re ending up looking like this with horrible line quality.
