Stop Resin 3D Print Fails! Bed Adhesion Tips & Tricks

[@ViralKiller]

rather have a tightly stuck print that didnt fail, than a failed one that did not stick

[@mikeoxlong1395]

I have a print that is just a sheet of plastic on the entire plate.

[@hz_rd]

A really under-utilized tool in lychee really helps with the removal process. I add a raft to my prints with a height of about 1mm and it allows me to lift the print off the bed easily with a plastic scraper. I've never ever had to use a metal scraper on my bed

[@cmcgill1990]

Yeh i was sitting here thinking why not just use the shapewall raft, my prints always just peel off once you get under the corner. must be a reason.

[@johnstephenson4428]

To both of you, I use rafts and I use the rubber mallet and scraper. I guess I will experiment with the bottom exposure. The other issue is the support structures never print.

[@thethubbedone]

If you're sanding a build plate, it's smart to place the sandpaper on a piece of plate glass (ideally a surface plate) to preserve the flatness of the build surface.

[@3dfilm.attechnicalvisualiz524]

That's correct. I think it's even better to use the back of a mirror. If the mirror shows no deviations, it is definitely flat. Danger! The back is sensitive and the mirror coating can be damaged.

[@thethubbedone]

@3dfilm.attechnicalvisualiz524 the coating on mirrors is normally on the back

[@solardile7143]

I found that pouring boiling or very hot water over the bottom of the prints help a lot to remove them! It softens up the resin quite a bit. It’s the same logic that goes into soaking before support removal

[@MrShinizor]

If your prints are that stuck to the buildplate, pop it in the freezer for a bit (be sure to put in a sealed container/bag first to prevent getting resin on all your frozen stuff). The cold shrinks the print ever so slightly ad it'll just pop right off

[@MechaMurphzilla]

one thing I started doing on prints that have been difficult is spraying IPA on the part that is adhered to the plate and it has worked really well so far

[@didjargo]

I never heard of flexible build plates for resin printers before. As soon as you mentioned the benefits, I went and ordered one online. Looking forward to never again having to chisel the prints off the bed, pour boiling water on them, or needing to re-calibrate the bed each time because I'd nudge the arm out of alignment with all of the force I needed to apply.

[@HenryCreations]

You might wanna just stick the tip of the scraper (it's just the tip) and use it to get air into the bottom of the prints, that will release all the little square rafts that are connected together. That is my advice. When placing supports, make sure they are connected and also get the tip in there using the holes of the build plate. So much easier. Más vale maña que fuerza!

[@Mowgi]

Just got my Mars 2 Pro after watching you for months. Haven't got it up and running yet, but I've been watching your videos to prepare myself. It'll be joining my two Ender 3's and CR-10 soon. Can't wait :D

[@chronosscollections46]

'I am going to get an angry test msg here in a few mins' I have the same problem lol I had to buy a weather proof plastic tub (to prevent the smell from getting everywhere in the house) to transport the 3D print to the garage so I can hammer away lol One trick I use on my printers to prevent print failures is after I clean the vat with a shop towel, I then clean the vat again, but this time with alcohol pads (the ones for glasses) idk why but those pads really remove any cloudiness left in the sheet and the best thing is... those pads don't leave any fibers behind and remove any fibers your paper towel left behind! It works every time for me! I hope this tip helps

[@Nosferatuklown]

Rifle Barrel Brush (commonly found at walmart/bass pro/sporting goods store) is a brass giant pipe cleaner with a metal tip - I'd say a 9mm size then just poke the back sides and they would come right out and be polished by the brass bristles

[@YoursTrulyThe1Pony]

I'm going to be buying the ELEGOO Mars 2 Mono MSLA 3D Printer very soon to see if it'll just give me more pain that creality cr10 v2 did. But by the looks of things the only thing that are problems with resin 3d printers are not supporting your 3d prints and bed adhesion. With the cr 10 I had a whole list of thing that went wrong with it. Bed adhesion, leveling the bed at four corners, bed levelers not enough to screw to level the bed right, warped print bed, too many wires, heat nozzle pulling off the print if you don't level the bed right, nozzle clogging, too many parts to assemble, even with the bltouch sensor it still didn't level properly and last uses twice as much pla to support some prints than a resin printer would. I was only able to print about few things, the preset models that come with the USB, and 3 masks; a scaled model of it, a large one and a successful print. The rest never turn out right

[@cjsn19]

I just started and I tried twice now but it's not even trying to stick to the build plate... it's just printing on the bottom of the tray... I'll try the sanding thing unless I should try to up the bottom exposure time first? I'm using Standard Photopolymer Resin - black

[@shrug_shrugsly]

Holy smokes. Thank you!!! MAN my stuff was sticking with a FURY yesterday and I want to print your dry brush palette. (You said something about drilling holes via Chitubox, which I don't quite get and assume that will be my big reason for fail. Bc at least now I think the "stuck to the plate" fail is much less likely).

[@pat3dxx]

I received my Sonic Mega 8K on Thursday. I have no issues adhering to the build plate with Phrozen's Rapid Black water washable resin, however I've missed 100% of my prints as it sticks to the FEP. I have never had any problems with my Photon Mono X 4K.

[@bayuocta7042]

Im using photon mono 4K and i found same problem when using standard resin such as Sunlu and Anycubic. I found my prints wont stick on the build plate. If i print for example 4 objects then the 2 objects wont stick on the build plate but it sticked on in the vat. But the 2 remaining objects prints fine. Any solutions ? Thanks

[@JohnWeland]

Hmm I have an Elegoo Mars Pro 3, first half-dozen prints went off without a hitch, next dozen jsut keep failing (even ones that printed right before). The don't fail to adhere to the bed as much as they -- at some point stop adhering to the supports or adhere to the tank maybe? Or they twist? Trying to print a set of D6 (six-sided dice) they start out in one orientation and then its like the print begints to rotate? IDK. its a learning process.

Do you have a video on how to best print thick minis that won't leak resin later? I have some solid 28MM tanks I have printed and everything is good so far but I want to make ssure I am doing everything I should be.

[@DRCsyntax]

You say high grit in this video. Do you mean lower grit? (More abrasive) Also, if you could; I've seen a lot of people basically beat their build plate to remove prints and it's rock solid. I tried that on my Mars 3 plate and threw my level off instantly. Is it just the plate for the Mars 3 or do I really need to crank down the bolts?

Cool vid! Just starting out on 3D printing myself, but power supply issues I know! I have an apc back up power supply unit hooked up to any device I have that will cause lost work in a power outtage or surge (drafting computer, Anycubic Photon Mono X wooo wooo!, etc.). Just make sure it is sized appropriately to your printer's power supply needs

[@mikeoxlong1395]

I had this weird problem on my Anycubic photon mono 2, the base few layers, the float, burn in just fine, but then the supports don't burn in. And, not all of them, only in a certain area which seems to be random for every print. I'm guessing it's the leveling problem but i leveled my plate just last night and i still had the same problem.

[@marioperez2443]

Hello, im printing translucent keycaps but have some issues with a waste layer of resin on the faces on plate direction. I think is because the light passing trough the model and cure this layer. Trying all the positions but can't fixit always have to sand it. Any sugestions?

[@thediscoman2001]

i have a warping issue with the prints it keeps warping on the bed any help

[@TomTrustworthy]

When trying to get things off the build plate, it has to be so much harder since the scraper is having to slice through resin that's cured into the holes. So you're not only scraping resin off the plate but you're cutting cured resin in each hole.

[@txwombat7826]

What Grit sandpaper were you using? - I didn't hear it mentioned.

[@justfubar857]

Thanks for the vid. I've done my homework and had several great prints with my new Mars 3 Pro. However, my first print after installing a Wham Bam flex plate, it failed to adhere to it. I sanded the new flex plate and just paused to check my test print and it hanging nicely.

[@garretthall9428]

So, I have leveled and leveled and leveled, and my printer is level, as well as the toolbox it's on, I use ptfe spray, and I have the bottom layers, all of 8 of them, curing at the longest time my printer says it can. And they still don't stick. What should I do now? Buy some sandpaper?

[@ethansdad3d]

Would lowering the first layer cure time also make it easier to remove prints from a more traditional bed like the Saturn? Nice detail mentioning the setting name in each of the major slicers.

[@UncleJessy]

Yeah that is certainly worth trying

[@mandalorianknight7002]

Affirmative, however I recommend setting up a couple of tests as if you go too low you won’t be adhering anything to your bed. I HIGHLY recommend enabling rafts as they give you a nice point of leverage to slide your spatula/scraper under to pop off your print. Should you be using a pre supported file from lychee (has a bunch of lines that the supports are built on) or anything that sits flush to the build plate: wrap it in a plastic baggie and let it sit for 30-45mins in a freezer, should come off with little to no problem

[@loveiswaytruthlife995]

[@stabbyronnie]

I love the "I don't know muh fahvuh Adam" print! Or the "I collect a check every first of the month Adam", whichever you prefer! There's also the "Disproportionately criminal Adam" moniker but I digress!

[@TAiiNE]

SO umm.. what if you have the weird issue that you get inconsistant sticking? Like some prints with the same settings, same resin will stick fine, others a little TOO fine, and others not at all? Even doing the same print files it feels almost hit or miss?

[@stevef6523]

You need to stop using individual support base rafts and use the lychee linked support raft which draws a single line between all support bases, but doesn't create a full solid raft. You just lift a tiny corner with a sharp spatula or razor and the whole thing peels off smooth and holds together. Burn in layers won't matter then, trust me, works a charm and uses a touch less resin

[@ingog.8424]

How about using a raft with a shape wall? Initially getting under the print is much easier with it, even with just a plastic scraper.

[@UncleJessy]

That can certainly help as well. I tried that once before with this same machine and still ended up with lots of cured resin in the holes

Just a suggestion. Use a light weight dead blow hammer with your scraper to help remove parts from the plate. I printed a stand that holds the plate surface verticle and frees up a hand.

Hi y'all, I just discovered this video. I'm having a lot of trouble and have changed my FEP film too many times (much more than I should). I use the WhamBam flex plate in my FlashForge Foto 13.3 4K & the bed adhesion is very inconsistent. My initial exposure time is set to 40. Sometimes the adhesion is perfect & sometimes quite the opposite and I'm using the Resione standard grey or white resin. Upon printing it seems the adhesion to the FEP is way to strong than it should & I have calibrated my bed far too many times as well trying to get to the bottom of this. Any idea to resolving this issue would be greatly appreciated. Quite honestly I think I'm loosing it. I need more consistent results. Thanks guys

[@Benneification]

Hey Jessy, why don't you simply use a raft? I personally prefer having trouble removing a successfull print from the building plate than the risk of my print sticking to the FEP resulting in a failed print. Removing the raft from the plate is quite easy with a plastic scraper.

[@Yarkspiri]

I'd recommend using a UPS system for your outlets but only for the SLA printers. Just make sure to use a 1500V version. I personally got this one. The type that you get will depend on how long your power outages tend to last. I personally use the CyberPower CP1500PFCLCD PFC Sinewave UPS System, 1500VA/1000W and while this one doesn't last too long it works great short power losses.

While I don't doubt the information given is correct, it seems incredibly odd to me to compare settings using two completely different prints.

Literally just tried my first print ever, and it ended up just printing the first layer basically directly on the screen.. But it didn't stick to the build plate.. And then trying to save the resin ended up spilling some of it. It was a huge mess and honestly quite frustrating.. But from what I'm getting from both this video and quick research is I might need to tweak my first layer exposure time.. And something else to do with The Saturn 2. Not being calibrated correctly..

[@aqhan]

Can you do a video what to do when prints regularly fall off their supports (e.g. Supports print perfectly, but the actual print sticks to the FEP and falls off its supports)?

[@cyrusvonkerogain9489]

There are 2 common reasons for this. The first is it is not properly supported. The second is the exposure time isnt enough, so the supports are two weak to take the strain. add stronger/heavy supports to the areas which have the largest amount of additional material above them, and increase exposure times slowly (to dial it into your resin. The temperature you keep the room, and the humidity also factor into your proper exposure times...so its largely printing calibration files until you get it dialed in. I like the Siryatech resin calibration file.)
