Spring steel magnetic plates
I see on the website that 3 types of spring steel plates are available for the MK3: Smooth PEI, Glossy Powder Coated Smooth PEI and Textured Powder Coated PEI.
What's the difference between the Smooth PEI and Glossy Power Coated Smooth PEI?
Can additional alternate plates be ordered at the same time as the MK3? Couldn't find an option on the website.
Thanks.
Re: Spring steel magnetic plates
At the moment there are no spare PEI covered plates, they are all being sent out with back orders...
the glossy and textured plates are powder coated PEI Directly on the Steel plate,
which promises to be more robust, once Prusa get a constant supply of satisfactory product.
the other plate uses 3m adhesive sheet to fasten the PEI Sheet, o the steel plate, and this setup is likely to be less robust than powder coating.
however since we should not need to use scrapers and chisels to remove the 3d Models, the PEI should last longer than it does on the Mk42 print bed on the Prusa Mk2 and Mk2S printers

Re: Spring steel magnetic plates
Im not sure why everyone keeps stating that you wont have to use the scraper at all. With the new sheet the printed parts will come loose for sure, but the brims are not affected and still have to be scraped off as usual. Same applies to some flexible materials (for which you have to use the gluestick, but still).
Re: Spring steel magnetic plates
You are correct, of course. However, my experience had been that the bed damaging comes from having to use a sharp scraper to loosen a big/wide part, or even a chisel to pry up one corner so the scraper can get in. That should not be needed here.
Brims and flexible work can be done with a gentler approach, less likely to harm the bed.
Re: Spring steel magnetic plates
These are great for getting brims and such off the bed without damaging the PEI

No good for loosening big stuck parts though.

Hey it seems like a great tool for the task, thanks! I'll definitely purchase one of those

Honestly who still uses that. I have never had the need in 6 years

And your printer also does not draw the nozzle-clening line at the beginning of every print?

Glue stick? When I’m printing on bare glass, sometimes PEI, I use glue stick to lessen the grip of PETG. I’ve had PETG grip so hard I’ve torn chunks of glass out of a bed, and multiple times I’ve had petg removal pull up me PEI sheet enough to create a visible bubble. Glue stick can soften that grip.
Re: Spring steel magnetic plates
We all do what we feel we need to do, if it doesn't work out the way we want we try something else. sometimes we ask for advise, and often there are more than one alternative.
I use Talcum powder for TPU, TPE and PETG, that doesn't mean its better than forehead grease or glue stick as a grip reducer, it's certainly not as accessible as forehead grease. but for some inexplicable reason, I prefer to find the talc...
I have never had good results with glue stick, that doesn't mean it's an invalid choice.
Some people don't use archaic methods, that doesn't mean that those who do, are in any way deficient.
lets play nicely. 🙂
Merry Festive season everyone.

I was actually talking about brims
Re: Spring steel magnetic plates
Buildtac is going to release something similar for the mk3
Re: Spring steel magnetic plates
Thanks for all of the info. Just ordered the MK3 and can't wait to get it (going to be a long wait, but I could have made the decision earlier so that's on me).
On the Order History page, there's info on getting other types of plates. Good info.
