Does anyone know why my prints are coming out like this? With all these visible lines and holes in the print. Is it just the resolution and infill I printed it in or is it something more?
A variety of reasons. If it’s repeating, maybe wobble in the threaded rod.
Maybe inconsistency in the filament diameter?
I’m interested in the outcome, I have exactly the same issue… Printing in 200ym with 15% infill. I did not try other settings yet. What resolution and infill are you using?
@Francis_Lee I’m pretty sure it happens with all filaments I’ve used. In this print I was only printing it at a 5% infill to reduce print time. So that have been the issue…
Looks like a mechanical issue to me. You’ve got a really low infill %, so the holes are probably going to happen without a higher number of top layers. I’d check belts, pulley set screws, and also that your hot end does not wobble on its mounting hardware. Do you have a picture of your machine?
@ThantiK I’m using a printerbot simple metal that I built about a year ago. Everything always seemed to print out well until a few weeks ago. The issues might have started when I upgraded my printer bed… The belts seem to be really tight. Is it possible that my belts could be too tight?
@Dante_Paniccia , it’s possible to have too tight belts - but it’s not all that common. They should definitely be snug. If you had to replace the belt though, I’d also check the pulley set screw - it could be just loose enough that it’s not freely turning, but the flat on the stepper shaft keeping it mostly in line.
A filled in circle from top-down picture would certainly help address the issue too. Circles are great for detecting backlash, and infill overlap artifacts as well.
Looks fine stop complaining
I have had problems like this, (on a printrbot) try printing at 200 microns.
Ok everyone I tightened the set screws on my extruder and it seems to have improved the quality dramatically. Thanks for the help
I recently fixed a lot of my quality issues on two of my printers that ended up being due to loose nozzles. Amazing the difference it made but drove me nuts because it’s so similar to over/under extrusion and wobblw. Another issue I have found is the heated bed cycle causing the bed to rise and fall. Proper PID tuning fixed that for me.
Acetone bath will help smooth it out, but you definitely have some wobble. Maybe try some anti-vibrational pads under the feet (in case of environmental vibration).
I’ve always found this guide handy in understanding print issues: https://www.simplify3d.com/support/print-quality-troubleshooting/
If your machine is suddenly producing worse results, then yeah, definitely look into why. That part’s results are worth rechecking your machine. Stuff like smoothing won’t hide those problems very well.
