z axis bleed mid layers??

[manakawari]

so i just started trying to learn my printer again after a few month break and my first print is showing z axis bleeding but not on the base, its in two separate areas mid print..what could be causing this?? unfortunately im using a resin no one else on here is using so im shooting in the dark trying to get it to work..its makerjuice G+ white ..i have the exposure at 2800...this is my first attempt with this resin so i dont know if its a profile issue im having with the resin or if its a machine or computer problem that is causing the bleeding mid print.

I'm moving this into Resins. There is no profile included for that resin. You have to find the correct settings on your own. All I can tell you is for that resin, you better leave the UV filter in the projector.

ok but z axis bleeding in the middle layers based on your educated opinion would most likely be what? im assuming over exposure and i was going to try to correct it with more dye and less exposure time but i just wanted to make sure that this isnt a symptom of a setup error or something else because aside from the z axis bleeding, the print seems to be printing and curing properly so im guessing this would be a good next step, what do you think?

Hi,

Sounds like you need to add more pigment. White often has lots of bleed too.

Thanks, last night i added quite a bit more pigment and im still getting it, id like to attach a photo so you can see and confirm this is indeed bleeding from over exposure...notice what appears to be large flakes protruding off the print, there were a couple more of those but they broke off..

That resin is not nearly pigmented enough to work on the Solus. The white color is terrible at stopping the powerful light energy from our projectors.

Is your UV filter back in the printer? You will most likely need to go into the projector settings and bring down the brightness well down and see if that works.

But again, this is something that you will need to figure out on your own. Most people on this forum only use tested and proven resins.

i figured id have a problem but i had already bought the resin and i was hoping that at least i could have a white option for prints where i dont need a huge amount of detail..im just going to buy the proto resin and i guess ill just have to use primer...no the uv filter is still in..sucks i was hoping to use a white resin for most of my work

I just noticed that your exposure is at 2800 per layer. You might want to drop that way down and see if that helps. Try 1000ms. Or even 500ms.

Thanks Monger, I did decrease the exposure but not as much as you suggested, when it was all said and done I ended up adding quite a bit of pigment so I tried lowering the exposure a little less than you suggested just to try and it worked and imo it worked well...not as good as the prints im seeing posted in the gallery but compared to my fdm machine its amazing.

I feel that if I can just get the text a little clearer , this resin will work for at least some of what I needed a white resin for and I can buy the proto resin for when I need a crazy amount of detail....one thing to note is that while the makerjuice g+ does appear to work (still need to dial in the settings better) the resin appears to only work for a single print...what I mean is, after a single print is completed, cleaning, mixing and straining the leftover resin doesn't seem to salvage it...after a single print whats left in the vat doesn't appear capable of producing a decent print so im needing to empty and clean the vat after every print

so as you can see in these photos, I lowered the exposure to 1500 and the print is almost good enough, I just would like the text a little clearer and im wondering if you are seeing signs over overexposure still or do you think iv maxed out the resolution potential of this resin? ..tonight I was going to try 1200 or even 1000 to see if I could get it better but I have my printer set up on the same machine as my other 3d printer, my milling machine as well as all my laser cutters so unfortunately I cannot run my solus until the end of the day where I usually set up my print and leave for the day...is there a way to set up the solus so that I can use my computer while it prints or is this still not possible even with the new software?

anyway, here is the print and for size reference its about the size of a nickel , are you seeing signs its still possibly over exposed? if I could get the text slightly sharper I think this resin will work for my white needs .

Yes, I'd say it is still overexposed without seeing the STL model. The lettering is not crisp enough and blurs together. The detail on the skull, teeth for instance, is blurred.

What exposure are you using to get these results? I'd imagine it isn't too far now unless your exposure is really short. Then you'd probably need more pigment.
