SPOTTING A BAD FEP! LISTEN TO THE SOUND! MARS PRO

- Just thought I would show you how a leaky FEP sounded like once its leaked a bit of resin out. The USB that came with the printer is so bad that it corrupted any data I put on it! Be warned don't use it! It put so much strain on the FEP it started tiny leaks at the sides which spread quickly! I saw a tiny bit of resin after each print but never understood how it got there and was in denial. I should have changed it waaaay earlier! easy to clean up at least!
Hear a slight stick can also just mean your print is adhering to the build plate and pulling on the the fep and its snapping back down. Thats why the call it a FEP.. cause of the sound it makes. ;) When you clean your VAT put some water in it before you start your prints and press down or up on the fep and see if there is any leaking happening, its a good way to check.
It was a leak. A tiny one. Glad i caught it in time. My rule now is if ANY resin is sticking the fep to the screen then there a leak.... unless you havent cleaned it properly.
@@Cloakfiend I just meant specificlly the popping sound haha. Thats sucks about the leak though for sure!
@@turkeygerky2781 Yeah a lot of testing is what I've been doing with this as I'm fairly new to resin printing but have learnt so much from people and my own experimentation coming from fdm printing. So I've pretty much been studying all the problems and weird sounds of the mechanics and fep and all that and what causes it and why. Not to mention all the thickness needs of supports required to prevent faliures. But shapes with large inner chambers can suffer problem lines from the models peel forces. Fdm is more reliable here. Sometimes you cant even out peel forces and it makes some designs difficult to print. But the quality is very good but its also more difficult to post process due to its brittleness. Curious how the prints last in the sun or in general even if painted or plated?
It's not called FEP because of the sound, it's the acronym of Fluorinated Ethylene Propylen. If you were serious ;-)
@@DerJuergen3111 it wasnt serious lol Hard to convey sarcasm haha its just funny that it does sort of make a FEP sound :P
Great call on inspecting the screen! I had my FEP leak and didn't think at all to check to see if the screen was stull flush. Sure enough when I checked it wasn't level and opening it up revealed there was resin in the crevice.
Super grateful for this post! I started hearing the exact same sound and paused the print to investigate. I basically had a little buildup on the bottom of the tray that was sticking. I pulled the tray out and made sure there was no leakage, it was fine. Then I took a dull plastic putty knife and scraped along the bottom of the tray and it felt like it was a little thick. After a little swishing and scraping, that thick feeling was gone. There were no chunks as far as i could tell. Slid the tray back in, started the print back up and no more sticking sound.
My print is 96 hours, generally my prints are 15, so well see how this looks when its done. Hopefully wont have any issues, im at 65% now!
Glaf to help good luck to that long print my longest is 9hrs!
did you try to create a vat mix program? if the resin has sedimentation in the vat, if you leave the resin many days in the vat, you can run the vat mix program before you print. just put the smallest object possible in the slicer, slide it outside the print area, adjust the layer high to the smallest possible like 0.001 and create a printable file, check for how much resin will be used it should be ZERO and you are ready to "print". it works like a charm for Anycubic printers.
Thank you! I just got a photon and I noticed it was making that noise but didn't know what it meant. My second print ever failed and i think the fep screwed up and caused this in the following attempt
thats why you put kapton tape between the screen and unit
.so if that happens it dont leak into your machine .your not having much luck Cloakfiend
No, lol, not at all!! gotta laugh though!
While I had it apart, I'd also be tempted to lay down some sacrificial strips of tape on the edges of the LCD in case it leaks again.
@@JohnJones-oy3md i tried but prints were not sticking afterwards. If I ever relevel then i may try again. Blue painters tape was too thick.
@H D yes but it was a bad fep this time around. This is a tell tale noise for me now.
@H D i usally use a ptfe spay .ive used glycerine thats in the cake making part in a supermarket that works aswell 50p a bottle ..i did hear ranx works well the stuff you spray on car window screens to repal the rain ..
Nice video! even my new one is very noisy! what did you use to glue the display back?
Double sided tape. I have loads. But its annoying it should come pre applied and you just peel it off.
I had this exact same sound on my printer just started to happen and I couldn't figure out why till I watched this video. I noticed my screen was raised slightly in one corner. So I pushed it down and changed my FEP/VAT and the noise went away. I did NOT have any leaks prior though, so I don't know what caused the FEP to stick to the LCD in the first place.
Maybe a bit of resin underneath? Always worth a check anyways!
@@Cloakfiend I always do check after each print and clean the LCD, so I know there was no resin on it :/
@@c3rber3s00Im a bit lazier. I didnt check. But you are right it pays to check. If you hear two sticks on a lift its always worth checking!. I was lucky in this occasion as i put some resin and saw the leak. but there are so many variables i guess its just one! A loose tanks can be another. Id prefer that over a hole in a fep anyday!
My dude, look up applying ptfe dry lube to your FEP and you won't have those sticking issues again :)
No it was resin on the underside of the fep. Ive come a long way since this video and learnt tons thanks to all the feedback and the 3d printing community. However pfte lube is a waste of time in my opinion. I tried it for a while and then tried it without and personally found it to make zero difference.
@@Cloakfiend good deal. I already had the stuff laying around for a different project so I thought it would be wise to apply it
@@RJWaynerium its good to experiment! But dont always believe the hype. People tend to jump onto bandwagons in the 3d printing scene. Same goes for the pointless test print calibration pieces. Total waste of time.
@@Cloakfiend I'd probably only do one of those prints as a sanity check but nothing too crazy. It's almost like people wasting filament going crazy with benchys on FDM printers
@@RJWaynerium lol, totally agree!! I think i did like 1 benchy in my whole 7 years of 3d printing. Print what you need and want! not other peoples random stupid tests.
Had a leak...replaced the FEP, perfectly I might add, still hearing that stuck-noise so there must still be a leak.... Way too much maintenance with this machine.
Yeah its annoying at the beginning. Ive learnt a bit more now. But have no idea when my new fep will break. So far so good but only time will tell
I have the Kingroon also and I am on my 3rd print in a week and I am hearing that sound. Do I have to stop the print mid print or can I continue printing and deal with it when printing is done
Deal with it later. Ensure no resin is underneath the fep after the print. Just clean everything underneath. If you know its dry before the print and theres a tiny bit of resin after, then you got a tiny leak.
Might just be static or not tightened also. But you should only be hearing one pop. Nowadays though if im honest I dont hear anything at the start. Only later, not even sure why.
@@Cloakfiend whew. Thanks! I paused it and no leakage so far so good. Thanks!
@@raginggamer2109 cool! just check properly after. I had a tiny leak for a while. But it might just be a random speck of resin or something! If its always dry under the vat and on the screen you'll be fine!
@@Cloakfiend yup, was just a tiny speck of resin from the last print
Just cover the entire screen with a piece of a tablet screen protector. Cut it to fit, tape it down, problem solved.
Yep lots of folk do that! Better safe than sorry!

wear gloves!
I must have gone through like 200 pairs in a week already!!
it really doesn't matter that much
@@Cloakfiend just get a single pair of reusable nitride gloves for $15. Your skin will thank you!
