Preface: I’m on my third cheap printer in the past ten years. I bought an Anycubic kobra neo a few years ago. I told myself I wouldn’t mess with doing anything to it, but I was running into issues because of low quality control. I put it away due to frustration for the past year and now needed to print something and just figuring out all the issues. Right now I’m looking into upgrading the part cooling fan as I cannot get rid of stringing even on low temps with PLA. I should just buy a good printer but I just don’t feel like I can justify it.
I am afraid to tell you there is no way not to modify a printer then.
Parts will wear out at some point on any mechanical machine, certain plates make you save money and give you better results (ex: cool PIE supertack), if your printer drops off residue you might need something to catch it, if you wantnfime details at the cost of print speed you will need to replace the nozzle by something etc…
Maybe look at resin printers ? They hold on for way longer but are wayyy more messy to operate, also resin emits more dangerous fumes than most usual plastic used in FDM 3D printing
