!!! CAUTION !!!
To all having problems with Mars Pro build-plate adhesion!
Short story: Try using Elegoo's water washable resin;
background:
I have found that the Elegoo Water Washable resin (WWR), has a rather high tensile strength when cured--and that it will adhere to a mirror finish build-plate just fine.
This is one of those "learned the hard way" things. As those who have been following this thread-->(Start Here...) know I bought a new "Pro' build-plate assembly a few days back. My initial impression was that its surface finish was too smooth (damned near mirror-like, see my posts above) and that was what was causing the numerous adhesion issues that have been reported. I had intended to break its shine with 220 grit paper tp test that theory, however through a series of unfortunate events I ended up scuffing it with a 60 grit disc.
On my first print--first print ever with the washable resin--the bottom layers struck like "it to a baby blanket' and had to be smashed off with a 2" chisel and hammer. i resurfaced the platen with 320 grit and tried again; a bit better but i still had to bang the print off the platen, and sand off some remaining resin (this gray washable stuff is HARD as a rock when cured).
I did a print with IPA washable resin and all was well. However going back to the WWR I once more found myself banging the model off the platen.
Considering it time for drastic action I fired up my 10" buffer and re-polished the build-plate to a near mirror shine--one more WW resin print and success--no platen adhesion issues and the model popped off the plate with a tap on thescraper, as it should.
Bottom line, if you do plan on using the WW resin DO NOT do any more than very lightly scuff up the build-plate.
FWIW I plan on bringing all this the attention of Elegoo's support team. They need tell "Pro" owners having platen adhesion problems to use the water washable resin....
