Re: Prusa i3 MK3 – PEI bug later 39 days printing

I as well take the impression that the PEI sheet changes over time and doesn’t stick as well as in the beginning.

But I e’er get information technology to stick without glue stick for PLA and PETG, just demand to be more than precise with the Z-level and slow down the commencement layer more, to arrive lay down well.
In my experience, the dishwashing soap + hot water + minimally abrasive kitchen sponge works very well. Perhaps check if your kitchen soap has any hand care features, that might mean it contains some oils.
I haven’t used acetone for a while since the soap works so well.

And I certainly have no interest in using gum stick all the time, information technology’due south a bit messy.

If you use isopropanol, it should be 99%.
Isopropanol seventy% may incorporate xxx% of something that worsens the bond to the bed.
And equally you mention, detergent and h2o is outstandingly good to clean the bed with.

Re: Prusa i3 MK3 – PEI issues after 39 days printing

I accept loved my new MK3, but am having adhesion issues with the PEI canvas. I am using 91% isopropyl alcohol before nearly every print, accept washed the PEI sheet with soap and water several times, and but finished washing the canvas with acetone twice. I notice that i just tin can’t become all parts to stick to the bed unless I use glue stick.

I haven’t used a kitchen scrubber, 2000 grit sandpaper, or steel wool yet, but I take read that these are likewise possible solutions to rough up the PEI canvas.

Any other ideas? Should I just keep using the PEI sheet with glue stick?

At offset in that location were no issues, and I was using seventy% isopropyl from the drug shop. Would denatured alcohol (mixture of ethanol and methanol) be better?

My issues has been solved cheers

Are yous able to elaborate what fixed it.

Re: Prusa i3 MK3 – PEI issues after 39 days printing

I accept been printing pretty consistently for about the same amount of time. I found with PLA keeping the bed to 70c and using brims were advisable stopped all of my problems with adhesion. I have used 2 different PLAs and then far, the Prusa y’all go with the printer and some Hatchbox stuff I got off Amazon. Zero issues since irresolute the Bed temp.

Re: Prusa i3 MK3 – PEI issues after 39 days printing

I got a new flat canvass, the theory being I’d go along one for glue (TPU or PETg) and one clean.

The new one, maybe at that place are other reasons, simply it’s giving me fits. I’m constantly struggling. I’ve done with soap, acetone, iso, and level level level level.

Sometimes it works, and sometimes I have to start xxx+ prints to become it working.

Perhaps they practise “break in”. Perhaps I should use the old one for “clean” and the new one for glue.

I’ve noticed dark spots similar oil spots sometimes by parts that don’t stick – and it was make clean going in. I DID discover going a lilliputian hotter nozzle temp made some stuff stick which wasn’t earlier.

Re: Prusa i3 MK3 – PEI problems after 39 days press

my experience.

Acetone and PEI are a bad combo, it makes the PEI brittle combined with the heating and cooling cycles requiring a new sheet every few weeks if y’all print ABS.

PLA:
91% or college booze higher the better. combine this with using a scotch brilliant sponge. (yellow sponge+light-green pad)
spray the alcohol on the bed. Scuff the bed with the dark-green pad gently . Mop upwards with a lint free micromesh material.

PEI:
spray bed with windex glass cleaner, mop up with micromesh material, do not use green pad.

nylons and TPU mucilage stick with water and sponge/green pad clean upwards.

the trick is the scour pad information technology scratches up the surface of the PEI and then that the first layer has more to seize with teeth into.

Re: Prusa i3 MK3 – PEI issues after 39 days press

I had the exact problem.

Later on I really cleaned the bed, printing has been wonderful. Equally a affair of fact, PLA is hard enough to knock loose information technology bothers me. PET is like superglue was used (and that’southward using Windex and intentionally fouling the bed surface with a palm impress).

The risk with using detergents, especially ones with antibacterial agents that are common these days, is they leave backside ingredients that keep stuff from sticking. You have to rinse thoroughly, and if you accept soft water, rinsing needs to be done a few times, drying with a fresh paper towel in betwixt rinses. It was such a problem I no longer wash with Dawn dish soap. I’ll wipe the bed with a glue stick, and rinse the glue off and dry out a couple of times. Then a serious scrub with fresh 91% alcohol. I’ve also used acetone with skillful issue, usually but a low-cal wipe is plenty.

Regular old Dawn has worked wonderfully for me. My sheet is coming up on a year of service and is nevertheless in fantabulous condition and has only always been printed on 1 side. At one point the wife switched from dawn to Palmolive and zero stuck to the canvass after using it, I used Dr Bronners Pure Castile while we had the Palmolive and PLA stuck to the sail like glue after a fresh wash with it. I guess unlike strokes for different folks.

Someone posted this a while ago, might help with choosing cleaning agents…

my experience.
Acetone and PEI are a bad combo, it makes the PEI brittle combined with the heating and cooling cycles requiring a new sheet every few weeks if yous print ABS.

IMHO as long equally you don’t “go crazy” with the acetone the PEI isn’t adversely afflicted. I generally wipe down once per month with fairly constant employ and non noticed any ill furnishings. Perhaps once per week or greater will cause problems.

Re: Prusa i3 MK3 – PEI issues after 39 days printing

I’ve used acetone almost weekly – and fifty-fifty more frequently (a couple times a mean solar day) when press “difficult” parts. Bed is fine except where PET adhered a scrap too well and I now have pry marks. Not sure what the nominal life of the bed is supposed to be, only mine is nonetheless working well many months later.

Re: Prusa i3 MK3 – PEI issues after 39 days press

I used Acetone in one case in the 11 months I’ve had my printer and experience information technology cleans no amend than Dawn. I’ve simply ever printed on ane side of my PEI canvass and the surface on the print side is almost as overnice as the side that’southward never been printed on. The large exception is the purge line.

Re: Prusa i3 MK3 – PEI issues later 39 days printing

I used Acetone once in the 11 months I’ve had my printer and feel it cleans no meliorate than Dawn.

Every fourth dimension I have asked her she says information technology isn’t her job. 😯

Approximate I’ll get reported now for non-PC. 😈

Re: Prusa i3 MK3 – PEI issues after 39 days printing

I put a strip of Kapton tape beyond where the purge line goes to reduce the effect of successive purge lines.
