Perfect Resin 3D Prints | Exposure Calibration Testing

hey everyone uncle jesse here were you a good boy or girl this year and a santa leaving you a brand new resident 3d printer under the christmas tree or do you already own one or maybe you just picked up a brand new resin 3d printer like the elgoo mars 3 here that i'm going to be using in today's video regardless one of the most important things that you can do when it comes to resin 3d printing is finding the proper exposure settings for the resin that you're working with so in today's video we're going to be running through three different exposure setting tests that you can run on any resin 3d printer and in fact you can print all three at the same time which should save you time but before we do that a word from today's video sponsor which is none other than elk that's right elegant i partnered up and we are doing a giveaway which you've hopefully heard of by now but if not there are links down below where you can find out more about it where we are giving away five fifty dollar coupons for you to spend over on elgoo's amazon shop we're also giving away an elku mars ii pro which is just a fantastic revlon 3d printer for you to get started with and we're giving away an elgoo saturn which is their midsize resin 3d printer that is a blast to print with if you haven't already entered that giveaway is ending in less than a week and you can find links to that down below and in today's video i'm going to be working with elgoo's abs-like resin as well as their mercury x bundle which is an amazing wash and curing station if you're interested in more information about any of elgoo's products that i'm showing off in today's video you'll find links to those down below a huge thank you to elgoo for again sponsoring today's video and this amazing giveaway one great thing about elgu is that they have a set of standardized profiles for all of their resins and all of their machines that are available through the website i'll links down below to that as well that's a fantastic starting point for you if you're working with one of their machines or maybe you have one that you think is comparable that might be a good place for you to look and see as a starting point but in general when it comes to exposure settings regardless if you're using ch2 box or lychee or prusa slicer 2.5 is typically where i start with my exposure testing and then increase or decrease from there and in a lot of cases if it's a mono screen resin 3d printer i'll typically start dropping it down below that 2.5 exposure setting one of the best parts about these exposure tests are that they don't use a lot of resin and they print relatively fast and more than likely you're going to want to rerun those same prints multiple times to determine what's best for your printer the resin and the print space that you're working in and a starter test i'm going to be using the default settings provided by elgoo for their mint green abs like resin so let's get those prints started all right let's take a look at it 48 minutes later and everything printed and it's looking good i was expecting this to print properly with those default print settings here and the reason why this took a little bit longer than your normal exposure settings test is because one of them is extra tall because it allows you to further test a print an actual print with some supports on it i let this clean for about one minute and now we'll take a closer look at it now taking a look at the exposure test that i've run here the one that you're probably most familiar with here is the validation matrix this is the one that you see a lot of people posting over on a lot of facebook groups or online or i posted it in other videos this is a again one that can print really quickly and provide you with some great insight as to your exposure settings for the resin that you're printing with and here one of the key ones that everybody focuses on this little infinity symbol here and making sure that the points perfectly align and aren't really sucking up into each other or that the bars down below are fully printing as well as that they can actually fit in between each of the openings or here on the other side are these small circles where you can see we have a whole bunch of individual circles but this side here not all of the circles have actually remained open for their particular holes this next one is a newer model created by the folks over at psoriatech similar to the validation matrix we have things like these crosses and openings that should have corresponding openings for every single cross here that we're seeing as well as you should be comparing and looking at how wide or how thick the actual crosses are similar to the ellipse up there we have a triangle piece a little carrot that we're seeing how that actually fits together we also have some circles and corresponding openings with those to see how those align and again the ideal situation here is that everything should have corresponding openings with each of the pieces then we also with this one you have a supported lattice cube that's a pretty cool test print to run off and print with so this is something that's a little bit beyond what some of the other calibration tests are and this is why this took so long to print even ceratec recommends pausing or canceling the print after you've printed the first handful of layers and not fully printing everything if you're going to be printing these over and over again just because you don't necessarily need to print this top piece unless you feel like you've gotten most of the bottom tests the way that you want them to look now this last one here is one that you might not have seen and i just recently found out about this by another youtuber named denny's wang who has created a number of different resin test files that you can freely download and use and i really like how simple this is compared to the other ones that are fairly complex and might be a little intimidating to read this is very straightforward where it's going to print the piece there's actually supports that are supporting the bar all around this and then there are catch plates that if this happens to fail while you're printing the catch plates in theory should catch that and if your exposure settings are working well you should see that all of the supports properly printed and are connecting to the top piece and there's no sagging or any loose supported pieces there now what you're going to want to do is rerun this test multiple times in different increments now for me because everything printed properly and to be honest this might be fine for a lot of you out there that are working with different resin printers the default settings and what you're printing it all is going to come down to exactly what you're trying to print and the level of detail that you're trying to get out of it if you really want to dial in those settings you can further refine these as much as you need what i like to do is since i've started here at 2.5 i'm going to immediately drop this down by 0.5 so i either like to go up or down by a good chunk of a number and then based on those print results i'll either go back up slightly or i'll start moving further down so just as a reminder i started off at 2.5 which is the recommended settings provided by elgoo and again it's just a great overall good place for you to start i then went off and printed some at 2.0 then down to 1.5 then to 1 0 and as you can see here a lot of these really did not print very well at all so started backing my way up here we could see i again was able to get some pretty successful prints at 1.5 and the results looked really promising so then i decided to go up by two or three here to 1.8 and then as well as go down to 1.3 as soon as i go down to 1.3 again things started to fail drastically so knew that i had to stick around this 1.5 range so here's a quick look at the comparison between the 1.5 the 1.8 and the 2.0 exposures for me when i look at this it's easier for me to see the details on the 1.8 and the 2.0 compared to the 1.5 the 1.5 printed and it looks decent but the details look much more crisp and clean things like the ellipses here are properly meeting at a point the lines here down below are more evenly able to slide in between each other compared to the 1.5 to the 1.8 or even the 2.0 so if i wanted to be a little bit more conservative with my settings i might go with a 2.0 over a 1.8 but definitely the bottom of the barrel here that i could shoot for is 1.5 if i was really looking to try and print something quickly but maybe not as accurately as possible and then just so you can see the results between the 1.5 the 1.3 and the 1.0 you can even see where the file itself is splitting into two when it goes down too low in your exposure setting i'm actually using the validation matrix provided by denny wang which is slightly taller which allows you to really test out if these are actually going to split during the printing process comparing this psoriatech exposure setting test here we can see again this is the 1.5 the 1.8 and the 2.0 to me when i look at this everything again still looks a lot cleaner on the 1.8 in the 2.0 compared to the 1.5 i also printed the full 1.8 test just so that we could see this cube up top and to make sure that these supports actually held intact during the printing process and all of them did i should also mention that psoriatech has a full set of instructions on how to properly measure and utilize their calibration test here i'm just simply doing the bare basics with this of just a visual comparison not breaking out my calipers and actually measuring things on the test and again at 1.0 and 1.3 you can clearly see print failures in this process here and then at 1.5 everything's looking really good and i'm not really seeing any failures or anything like that even with the micro supports in there and then with the 1.8 and the 2.0 everything looks really solid so after running all those exposure tests and landing on one that i believed to be the perfect exposure for this mint green resin on the mars 3 for my workspace here i went off and printed this bust from fotusment this is one of his latest boba fett busts that are available through his patreon and i have to say it printed phenomenally i'm not seeing any issues with supports or the parts adhering to those supports throughout this entire print and it was a quick three hour print with the settings that i ran with here on the mars three and while i'm cleaning up this print i did wanna say a big thank you to all my patreon supporters for your continued support here on the channel if you're interested in my resin 3d printer settings as well as my support settings you can find links to that in my patreon down below and our prints are all cleaned up and everything as expected looks amazing all of the details are nice and crisp on this photocement does an amazing job with all of the models that he makes and no exception here with this boba fett file that i'm very excited to get printed and a fingers crossed will actually end up painting this and i was previously running into some failures with the machine because i was printing at a 0.15 exposure setting so i'm really happy i went through this process with you all and detailed this out because now i'm going to be rocking the 1.8 setting which i believe is near perfect for my print space this machine and this particular resin keep in mind that all those things might vary depending on even things like temperature in your print room i'll also have links directly to all of those exposure setting test prints there that i went off and printed i should also mention that denny's wang has a an amazing youtube channel have just recently found his channel and loving the content that he's producing there and also has some other calibration tests that you can run off in print like an anti-aliasing calibration print a vertical access print as well as a bed adhesion print files that are all free to download and run off in 3d print and let me know down in the comments below if you have a different way that you like to run your exposure setting tests on your resin 3d printers i'm always interested in hearing how others are going about this hey thanks so much for watching and i'll see you next time bye now you
