  • The problem with new PEI sheets everyone sells, is that they make the PEI so thin that it wears out so fast. It’s like when they go to cut a slice off the PEI tree, they damn near miss the whole tree. And the popularity of textured sheets doesn’t help either.

    I have a smooth PEI sheet that came with my Prusa Mk3s 6 years ago. It has 1000’s of hours of print times on it. After about 4 years of heavy use, it just wasn’t much good anymore. And I didn’t feel like buying a new sheet, so I took the chance and very lightly hit with some 1000grit wet/dry sandpaper to renew the surface. It now holds better than when it was new. And I can probably sand it again if it ever needs it. But new PEI plates aren’t coated half as thick either. So my Bambu plates will have to be replaced at some point.








  • FDM printing ABS/ASA is far easier and safer than resin printing since most CoreXY printers are enclosed these days. A simple fan and ether venting to the outside world or through activated charcoal air filters is a relatively simple procedure. Printers with all of that filtration are easily purchased these days. Even vapor smoothing can be done outdoors if it’s warm enough.
