Hello folks,
Tapping the Hive Mind here if you let me
?
.
I've been struggling with an issue with my builds, regardless of the nature of the resin and the settings.
Basically, some layers seem to peel off as if not adhering fully to the build. Pictures below.
I used Anycubic white resin here in 50 and 20 micron layers. First one was cleaned with IPA then detergent, the other with two baths of IPA.
This seems to show after the curing process and thus I suspect I make a mistake with either the cleaning or the curing.
I checked a the vids and guides I could find but couldn't find a solution to this.
Any suggestion folks ?

what are your exposure settings (base and normal, IE 60sec & 8sec)? Was the model on the build plate or was it placed on supports?

Hello Tim. Both were placed on supports. First one was straight, second was inclined. Both were 40s & 8s, which was matching the big holy spreadsheet of resin settings.

Hi Merv, thanks for pointing out this resource I didn't know. More reading and testing for me!

that first image looks like it should be a flat bottom rather than wavy. Without seeing your support configuration (perhaps not enough, causing the part to flex), there could be under exposure as well which will make the part more soft and flimsy. I'd check the supports to see that they are dense enough and maybe try increasing the exposure time by a second or two if that doesn't help.

Thanks Tim. Will check that out on the next builds. It's very possible I didn't use enough support.

Some useful reading..For what its worth I reckon to angle both ways off the build plate so tip back and slightly sideways if that makes sense..30 degrees off flat and maybe 10 degrees tilt..supports I do auto 50% in chitubox then go around,delete stuff
in the wrong place but do all around the edges,corners especially and all extremities...partly to force the resin to print there and partly for support..I think temperature plays a great part 25c minimum, 20% inclusion of a flex type resin will help reduce brittleness , resin brand / type / colour I don't think there is a great deal of difference to be honest..A base colour that will help with painting is as good a guide as any...for me...and yes,some guys always print flat off the buildplate some never have buildplate issues, some never have to change a FEP and some never have failed prints...These people I salute..I'm not that good..or that lucky..or I'm a bit more truthful....Just tickle along quietly and learn from the ones that didn't work..because when it does...Oh Boy
:)

"the big holy spreadsheet of resin settings" also indicates that it is a reference setting and (environment) temperature can be of influence...
Possibly a combination of not enough support and under-exposure.... (under exposure keeps it soft, suction will do the rest with the unsupported parts)
