Hey there, first post – hope it’s okay to put out a request for some advice. I just started 3D printing a few weeks ago (got an Ender 3 S1) and contrary to seemingly everyone else online, I’ve had no issues whatsoever with bed adhesion, rather the opposite.
Mostly to this point, I’ve been using ‘EconoFil’ PLA from filaments.ca (which was tricky to remove until I bought a better bed spatula-thing). Yesterday I got a roll of Overture ‘Eco-PLA’, which I’ve printed with a couple of times using organic supports, and both times has left a really stuck-on, almost chalky layer of filament on the bed. This isn’t so bad if I’m printing with the same filament afterward, but the Eco-PLA is ‘Midnight Black’ and I want to switch back to the Econofil for another model, which is ‘Bone White’ and I don’t want the bottom to get stained with the leftover Eco-PLA.
Has anyone had any similar issues? Any foolproof technique for removing stubborn, very thin layers?
I would recommend a PEI print surface like this: https://www.amazon.ca/gp/product/B08L39BFVJ
Most of my bed adhesion issues (too much or too little) went away once I got this.> Ender 3 S1
EDiT: I should say I only ever printed with PLA since I got the PEI sheet. I know PETG can bond to a PEI surface, so be careful with that.
