I’ve had a MK4S for over a week now, and 100% of the prints I’ve tried to make on the textured sheets have partially or totally failed. PLA prints beautifully on the smooth sheet, but PLA, PETG and ABS, I think I could print on the surface of a 10 inch tank of oil with more success than the textured sheet. Plastic doesn’t stick to it. I’ve wiped it with isopopyl, I’ve washed it with dawn…it’s a bad print surface and I want my money back.

I clean mine with isopropyl alcohol every other print or so.
So, to clarify, you’ve EVER gotten yours to work? EVERY SINGLE part I’ve printed on that sheet has partially or totally failed, and I’ve cleaned it repeatedly.
I’ve been printing on glass and glue stick since the Obama administration, and that actually works. You know what? Fuck magnetic sheets, I’m going back to glass and binder clips, because they actually goddamn motherfucking work. I’m sick of people unsolving problems.
Yeah its been better than the smooth one, but I long ago got into the habit of using hairspray on every print.
I find the smooth one works adequately for PLA. I don’t have a satin one, and I think I’d have better luck printing on an inch deep tank of cod liver oil than the textured sheet.
I’ll go back to printing on glass and glue stick before I start fucking around with hair spray.
I’ve tried all 3 and found hairspray the absolute winner of bed adhesion and it’s not even close.
I’ve printed PETG on glue stick on glass since Obama was president and until this week I would have told you PETG doesn’t peel the corners up like ABS does.
Grease is bad for those PEI sheets. I wipe it off with alcohol before every print. They need to be hot, too. Around the glass transition temperature of your material. I exclusively print PETG. 70°C will fail, while 85°C will stick great.
Glue stick on glass. Got it. I’ll go to Lowe’s first thing in the morning to get some cut to size.
I had issues with mine, nothing was sticking to it causing 100% failures. I forgot where I read it but I ended up scrubbing it good with one of those slightly abrasive green pads in warm dawn dish soap, drying it with a clean microfiber cloth and putting it on the bed with the heat set to 60c for a few minutes. It now works extremely well with pla or petg, I just wipe it down with a bit of 90% alcohol between prints. Never had any issues with the smooth and satin sheets.
You mentioned using Dawn. Did you use the hottest water you can get from your tap, and maybe wash several times? I remember having lots of trouble with my textured sheet initially, but after a few good scrubs with really hot water and dawn, it finally started working just fine. Like there was some residue from manufacturing left on it that took some work to get off.
Per Prusa’s Knowledge Base I washed it with “warm water (not hot!) and a few drops of liquid dish soap (not hand soap).”
I’ll go get out my canning pot, boil up 5 gallons of water, and scrub it with a brillo pad and some brakleen. Can’t fuck it up any worse than Josef himself did.
Yeah the texture sheet works, but I would never use it with PLA. I only use mine for TPU and sometimes polycarbonate. Anything else is either smooth or satin sheet.
Yes. Mine has worked amazingly well.
Back when I had a Prusa I never had any success with the textured sheet and PLA, however it worked perfectly with PETG.
PETG, PLA, ABS, I haven’t gotten anything to stick to it. It’s “powder coated” but it doesn’t say what powder. Is it teflon?
Stupid question, you sure you are using the right bed temperature? The feature of a PEI textured sheet is that it self released the part when the bed cools down,.
That is not a stupid question. That is a valid question. I’m using Prusa’s provided templates in PrusaSlicer. This includes Prusament PETG with the Prusament PETG template. This is a stupid question: As many parts as Prusa makes printing Prusament PETG on Prusa printers with Prusa build sheets, wouldn’t that material template be well tested?
Its PEI, powder coated. Everything should stick to it with out any adhesives. Soap?
I’ve seen instructions saying to, and not to, wash it with soap and water. I have washed it with Dawn dish soap and warm water, I’ve wiped it off with isopropyl alcohol, doesn’t fucking matter. Nothing sticks to it. When we’re done with Greenland, we need to do Czechia.
