I will never regret getting rid of my Ender 3. It’s basically a self-imposed challenge mode. People are proud that they can print things on it despite the printer, not because of it.
After twenty years of self-built printers, I got an Ender 3 to stop having to fiddle with the printer every time I went to print. It was glorious. Not sure why the Ender hate, they work well, especially for the price.
My ender 3 wasn’t my first printer, it’s not my only printer, and some days it’s my best printer. It’s actually underrated as a platform.

I would check that the print bed is heating evenly. Everyone has mentioned cleaning, that’s definitely a good start, too. But it looks like bands where it’s not sticking. From the image’s perspective, about 1/3 up is a band of poor adhesion, and then at the far end of the plate. IDK how the heating elements are designed, but that could be a. Issue. Otherwise the build plate is warped in almost an “S” shape. Some leveling will help, but not fix a warped bed.
Also, the material deposition looks very thin in general. Make sure the z-step is set correctly, slow down the first layer print, and make sure the temperatures of the bed and hotend are right.
I have an older printer with a warped bed and basically brute force the adhesion with a slightly thicker base layer and then normal layers after that.
Creality. (Sorry, I had to)
Could be a few things. Bed adhesion could be an issue. Be meticulous in cleaning the bed. Also this bed looks open so it could be cooling off too quickly.
The tears look very specific and repeated so maybe tweak fill settings to be denser.
The top is really bad and may have a bed levelling issue.
Looks like head collision. Make sure the bed isn’t baked on the other side causing bumps. It’s odd that it’s multiple spots so definitely look under the bed and make sure everything is clean. If so then check out the bed for breakdown in the top layer. There’s not a great reason other than z collision for that tearing.
Adhesion and bedmesh calibration should solve the explosions/under extrusion in far back. The stringiness/ bad line-line adhesion is from bad z level calibration.
I have 2 ender 3s, and they were awesome. I learned so much about engineering, gcode, and flashing firmware. I spent so much time fine tuning print parameters and installing mods, and I was able to get decent prints. I moved and picked up a bambu P1S, during a black Friday sale a few years ago. My enders are still packed and my P1S has just worked, giving me prints quality and consistency I only could have dreamed of using my enders. Now, I just need a project to recycle my enders parts into.
Long story short, use teaching tech ender 3 calibration guide, dry your filament, and install auto bed leveling probe that will account for warped build plates. https://teachingtechyt.github.io/calibration.html
