Create Perfect 3D Resin Prints by Finding the Optimal Layer Exposure Time

[@sirayatech2]

We are from Siraya Tech, and we always enjoyed your videos. This particular video is very helpful for many new users. . We also like to share that XP2 is great for brittle/hard model resin but can have issues with more flexible resins, including Fast abs-like and tough resins like Blu. This is likely due to the xp2 model is too easy to print, and that flexible resin often has a wide printable range that would make it very hard to judge. So a 1.5s may look just like a 3s one, but 1.5s may have a problem printing a real world print model. Several attempts have been made to address this aspect of the XP2 model, and we have shared this finding with the amazing Photonser who created the XP2 model.

[@beefknuckles]

Love your resins

[@heramann6916]

Wish I could love your resins but we can't get none in Brazil. Still respect your brand tho, only read good things about it around the internet

[@JBGecko13yt]

I have nothing but failures with the mono 5s with the anycubic resin. I just started a new print with Sirayatech after installing your settings file for the resin. Well see what happens.

Yay! My pleasure mate, glad to of helped 😊

[@JD-sb7mq]

same. I posted in a facebook group about recommended settings people could share and the majority of them were morons basically telling me to figure it out myself/“no shortcuts in this hobby”(🖕🙄 to them). There was maybe one or two people that commented on the post that actually provided guides like this one here. Some people are meant to be teachers by how natural it comes to them to explain things in a way people can understand and their sheer amount of attention to detail as well as patience. Other’s need a whole separate course on people skills and how to teach effectively, because they know nothing of humility with the amount of arrogance I got from comments like that. We join these groups/forums and conversations to learn from one another not just gloat about how amazing a job we did getting something to print correctly. Anyway, after seeing this well put-together video I’m subscribing. Thank you!

[@peterdocter4659]

The Cones of Calibration work way better for dialing in the exposure time, they give a real easy to "read" result and tuning becomes really easy! (just a tip for those watching this later on)

[@killiandw]

I struggle with the cones could never get them perfect

[@peterdocter4659]

@killiandw Also depends on the resin of course, state of you FEP and mostly constant temperature.

[@richarddespres8011]

Thank you for this video. I ran the basic test piece that came with my Photon Mono SE and used the vase layer setting on the box of my resin. I've now seen that a) the setting I settled on is way over exposed, and b) that this over exposure is part of the reason it feels like I need a jackhammer to get my prints off of the bed.

[@Core-Electronics]

My pleasure and cheers for sharing you experience 😊

[@mjustice34]

Thank you for this video. Great tips. Explaining things others never take the time to explain. For newer users like myself all these numbers a settings are greek to me, all these crazy offsets x,y,z, , bottom / top, speeds, off times, etc is just insane, however after you finally taking the time to explain this I'm actually getting results, I kept over exposering, constantly having to replace damaged fep which is a constant set back, so thanks.

[@ET-gr9yw]

The most detailed printing advice I've heard so far. Thanks. What can cause the problem that the printed model is rich in detail but does not harden but remains soft, even if I shine it with UV light. Thank you for your answer

[@Core-Electronics]

There are different types of resin. Some newest types are flexible and even after curing they will remain flexible. If this is happening to your rigid resins I'd recommend hitting them with even more UV light or getting a new batch of resin. After a couple of months of the bottle being opened the Resin gets old and then can produce weird results.

[@AlenHR]

I'm using Anycubic mono X with their basic resins in a light color. My perfect print settings (on a new printer) were: UV light strength @70%, 1.5 sec exp time, 6 bottom layers, 35 sec exp time. After 50 hours of print I started getting underexposed prints so I upped UV light strength to 75%, everything else stayed the same. Still getting perfect prints. I change FEP sheets every 25 hours of print time or so. I printed about 5 liters of resin (printing mostly full build plates).

[@Core-Electronics]

Cheers for sharing mate 😊 love hearing success stories and your experience with your machine over time.

[@atomant8800]

im late to the party but this is an amazing video! I kept getting failed prints with my anycubic photon mono x2 using anycubic clear resin and manufacturer settings (2.5 sec exposure time). I suspected that it was to low exposure and wow did this test validate that! I still need to dial it in, but i should be between 3.0 and 3.5!

This is a great video thanks, the only thing I would add is ,3d printing pro made a video explaining why more than 4 burn in layers doesn't really make a difference

I'll have to check it out, my experience has been more burn in layers has resulted in better model stiction to the buildplate.

[@RACKSO99]

Wow, I wish i knew this before starting to print, would be good if this was mentioned/included in printer manuals. Defs gonna do this now. Ive been trying to compensate my slightly enlarged prints manually in the CAD files and I've had lots issues of under/overexposure particularly with clear resin.

[@michaelhollanshed5729]

EXCELLENT INFORMATION! THANK YOU SIR!

[@julianf1970]

This is the first video of yours that I have seen and shall look forward to others that you do. I've owned a resin printer for less than 2 days and NOW I realise why the exposure time is so important and what the difference is between a Normal and Bottom layer. Your suggestion of a c.10x increase in exposure time to establish the bottom layer is invaluable. I'm also grateful to you for explaining why manufacturers deliberately 'over-cook' (so to speak) the exposure time to begin with. Not a conspiracy, but a guarantee that models produced will definitely work and so lend confidence to the newbie owner (i.e. me). So very many thanks for this wonderful insight. Forgive a naive question, but I notice that my Photon Mono 4K has a very similar appearance to your Crealtity (other than the obvious difference in colour to the UV casing). Are they the same or sister companies, I wonder?

[@Core-Electronics]

Very glad to of helped 😊 more videos on Resin Printing in the pipeline too. In regards to similar appearance this has to do with them utilising very similar technology and implementing it in a similar manner. This implementation is by far the most common way to print resin currently, you'll see many machines with similar appearances made by many manufacturers, and is now referred to as 'traditional resin 3D printing' (this technology is so young using the word traditional does seem a little silly). If your curious there are many different ways/methods to 3D print resin, take this machine here which has a very novel resin printing method - www.fabbaloo.com/news/rocket-1-fast-and-accurate-resin-3d-printer

[@Guardian_Arias]

After 5 years of FDM printing I finally bought a resin printer, on my first print I used your calibration matrix, well I got extremely lucky I used 50um layer height and guessed a cure time of 2.5 with Conjure Rigid Clear Blue and I can count 13 Holes and 13 Pins. Being around aircraft fluids and eating food with literal black hands I didn't think I would mind the cleaning. Unfortunately, it's not as satisfying to rush to the printer and pull off the print. The print does look amazing, and it was even more impressive when I pulled the STL files into CAD and measured the 13th at 0.100mm and the 13th hole was actually a SQUARE measuring at 0.070mm x 0.070mm. Wish me luck, I have some soul searching to do and hopefully I can reconcile this..........

Big thanks mate 🙂! More on the way.

[@WTF_BBQ]

I bought my resin 3D printer with the expectation that it is more accurate than FDM printers for making functional parts. I was very disappointed that things wouldn't fit properly. In fact, they don't fit at all. I will try these calibration methods and see if it'll improve ....

[@Core-Electronics]

You'll be able to produce functional parts, just be aware each time you use a different resin it will affect Dimensional Accuracy. Run off a couple of Dimensional calibration prints to nail it. Produce a XYZ Cube which is perfectly 20x20x20mm and you'll be good to go. If too small/big scale up/down in your slicing software. STL Link to Cube - www.thingiverse.com/thing:1278865 Then when you are producing perfect XYZ Cubes start printing your functional parts, making sure to scale the component to the same amount.

I was hoping you could help me out with this, like the proper exposure settings. I have been messing around with the exposure times for the WW resin for about 2 weeks now and i cannot for the life me find the correct exposure settings.

[@Core-Electronics]

Thank you for your very kind words 😊 and Elegoo water washable resin isn't one I have used yet. Is the process outlined in the video not working for your set up?

[@davidc3150]

Thanks for the recommendation to this video. What would you consider to be the optimal times to wash and cure on the post processing? Since you state IPA kills the most tiny details and curing could also cause overexposure? Would you share some recommendations on the optimal time spent washing and curing please? Thanks again for all your wisdom

[@Core-Electronics]

I'll hit each module for 10 minutes in the IPA Wash station at low. Then I'll hit the models with 5 minute cure at slow speed, rotate the model so the bottom faces up, then do another 5 minute cure. After that it should be all good to go 😊 If it still feels tacky I hit it with 5 more minutes of curing.

[@WilliamMorrison1]

You could dial-in your exposure setting time using a binary search instead of printing multiple times with .1 second variation. save yourself time and material. i still appreciated your video and detailed break down greatly, just a small suggestion.

[@Core-Electronics]

That's a great idea! Practical uses for computer science 👌

[@TheRealViniciusSilva]

Sorry for my ignorance, what is a Binary search?

[@WilliamMorrison1]

@@TheRealViniciusSilva A way to find whether an item is in an ordered set very efficiently. Let's say the set is in ascending order. You'd start with a center item and see whether the value you're looking at is bigger or smaller than the item you want. If it's less you find the middle item in the latter half of the set. If it's greater you find the middle item in the first half the set. Repeat till you find your item, or nothing if the item doesn't exist. In this case, you can think of the calibration models as a set. If you know, before printing, about what underexposed prints look like, and about what overexposed prints look like, you can use this same process to fine-tune your settings using less time and material.

[@TAiiNE]

So... these test prints to calibrate a printer is good and all, but I did run into a very... odd issue. I used this to home in the settings on some elegoo standard translucent resin and yeah, this and a few other calibration prints came out better than I hoped, both default settings to strart with and homing it down. But in really printing something... no matter what it was, or the orientation of the object... the side facing down printed flawlessly. But the side facing up, facing the build plate and around supports looked to 'gum up' or colect a mass of resin and cure it as well. These all being prints I've had no isues with in other resins. So the side facing the build plate would come out gunked up, thick globs everywhere, bad warping and so on. I'd share photos but youtube has been auto deleting all comments with links in them, even if I try and get fancy with it. Could this be just a bad batch of resin? Or some other factor I'm unaware of when it comes to clear/transparent resin? Could it be due to printing in winter though the temp inside and around the printer are with in the working range? It just seems no matter how I adjusted the settings even using settings ment for like the standard gray the same thing. If facing to the side or away from build plate, prints sharp and clear... face build plate and it's a mess. I am going to be switching back to the gray just to be sure something isn't badly fudging up. But this is starting to bother me as I was really looking forward to doing a few things with the translucent.

[@Core-Electronics]

Thanks for sharing mate, this gunk that you have on the bottom layers when you use transparent resin could be any number of reasons. You've highlighted the main culprits that I reckon it is, old resin and temperature. Resin does last a long while sealed up and out of the sun. Make sure that you have filtered it so that there isn't any cured/semi cured resin hidden in there. Its particularly hard to see this with Transparent Resin. With the right setting temperature can be overcome, I've seen a fellow produce resin prints in the snow (kzbin.info/www/bejne/d5SVXqekeLiqh8U). With the images I can help better, come post them on our Forum 😊

[@Core-Electronics]

Just had a look for you and your absolutely right, the options available with that machine are less than they should.

[@PhilXavierSierraJones]

I'm a little bit confused about the holes on the left side; Is it supposed to go all the way through, or is it supposed to be plugged up half-way through as if there's a backing behind the holes?

[@Core-Electronics]

What you are observing is the resulting model created from Bottom Exposure Times VS Normal Exposure Times. The Bottom Exposure times wont keep the model design perfectly dimensionally accurate but will enable model adhering to the build platform. So don't focus your keen eye on the first 4 layers that are Bottom Exposure Time, we're more interested in the result from Normal Exposure Times (which present themselves at higher layers)

[@Martial-Mat]

Oh jeez, the caveats at the end were depressing. To hear you describe it, I should run a test print series before EVERY print. My climate is constantly changing, the age of my filament and printer are constantly changing, and of course, my resin batch mumber is changing.

[@bayuocta7042]

Im using anycubic photon mono with anycubic resin. I ve just found 3s exp time recently. Is it okay? I used resin xp2 validation matrix and printed perfectly.

[@dKeprintlab]

Thanks for this video, I'll definitely run more tests! Do you think the 10x for bottom layer works for water washable resin too? And how many bottom layers do you suggest?

[@Core-Electronics]

My experience with water washable resin is limited but I would treat it the same and follow my general rules for normal resin. So I'd have 8-12 bottom layers and a bottom exposure time that was 10x normal layers.

[@HotCarTrack]

What about the instructions on the bottle of resin, for example I'm trying out the Elegoo ABS and they recommend 8sec normal exposure & 60sec bottom exposure. How accurate are these settings when printing.

[@Core-Electronics]

Resin Manufacturers, much in the same way as Printer Manufacturers, want your first couple of 3D prints with their material to be successful. This means normally providing settings that are over-exposed, so that you won't have models falling off the build platform. I haven't done experiments with that particular resin but to me those numbers seem large for a Mono-screen Resin 3D printer. I would definitely run test on it with my particular printer before committing to large or intricate prints.

[@HotCarTrack]

@@Core-Electronics Thanks for getting back, I also thought those settings were a little over the top however after a few test prints they seem about right for my 28mm prints.

[@xevenau]

When you say you have to do another exposure test with a new resin, do you mean retesting the resin of the same kind, a resin of a different kind, or both?

[@Core-Electronics]

Nice question, resins of the same brand but different colours/transparency are definitely worth re-running these tests as the exposure light will travel through the resins differently (in regards to both penetration and dispersal through the liquid). An argument can also be made for re-testing the exact same brand and type of resin if your are using a new bottle (as variance can occur between batches from the manufacturer) but normally you will be good to go with the same settings.

Where is the dxf file for the Pokémon that was made? I'd love to print that one myself

Kind of a side question. Why would you orient the model (Gengar) so that all the “woodgrain” layer lines are right in the middle of his face? I would’ve oriented him so those layer lines would be at the top and bottom of him, largely hidden.

I printed this little guy with his feet basically to the build platform. Seeing those edge layer lines (particularly around the front teeth) was a surprise to me that I only noticed when we put the HD zoom in really close camera to work. No matter how you orientate the model, because it is effectively a sphere, you will always end up with these layer lines somewhere. The best way to avoid seeing these layers (which are super hard to see with the human eye) is to take advantage of the Anti-Aliasing settings and use a value ~8x. That or use smaller layer lines. Hope that helps!

After the first Matrix was done printed and removed from the Platform, Do I have to Level it again or is it possible to print the next exposure test right after that?

[@Core-Electronics]

Once you have leveled the platform once your good to go. It is good practice to do so once every 6 months, but so long as those screws (that you tightened to level the build platform) are still tight the build platform will still be level. Hope that helps 😊
