Vroom - Faster Resin 3D Printing - How To

hey everyone uncle jesse here as you might know i'm a pretty big fan of resin 3d printers not only do they print absolutely amazing and give you really finely detailed prints but for the most part they print pretty quickly regardless of the build volume of your machine well in today's video we're gonna be talking about a new print methodology called vroom that's right we're going fast and furious in today's video basically taking everything that you know about your resin 3d printer settings and throwing them out the window but before we do that a quick word from today's video sponsor today's video is sponsored by the folks over at elgoo the makers of some seriously amazing resin 3d printers and accessories i have been a big fan of elgu ever since getting a hold of my very first elgu mars back in the summer of 2019. ever since then it's changed my perspective on 3d printing and more importantly how great an amazing resin 3d printers can be in this video we're going to be utilizing the elgu mars the elgumars 2 pro and the elgoo saturn all printed in elgu's abs like gray resin and cleaned in their mercury two-in-one washing cure station if you're interested in any of the elgoo products that i'm featuring in today's video you'll find links down below thanks again to elgoo for sponsoring today's video so i'm on a lot of different facebook 3d printing groups and over the past month plus i started seeing folks posting about vroom and printing really fast and i really had no idea what it was really referring to and some of you out there might be in the same boat or maybe you're just hearing about this for the very first time well i'm happy to say it's really not that confusing or all that complicated yes there are some people that have to go out there and modify g-codes on their machines or their firmware on their machines in order to further enable this but the good news is pretty much anybody out there that has a resin 3d printer you can test this out today on your machine with really little to no effort other than just changing a few settings in your slicer profile also a huge thank you to the atlas discord group they were a huge help in me better understanding all this and compiling some of the information here for you guys today of links down below to the discord channel there for the atlas group they also do a lot of support generation tips and tricks and solutions there for anybody that's interested in better resin support settings so as i mentioned you really just need to look at changing three of your lift speed settings within your resin setting profiles so what i did today with a number of the prints that i'm going to be walking you guys through here in just a few minutes is i left all of my resin settings the exact same and only modified my lift speeds in ch2 box that's going to be your bottom lift speed your lift speed and your retract speed if you're using lychee slicer under the burn-in layer settings it's your lift speed under the speed settings it's your lift speed and your lowering speed i should also mention that i can't guarantee that this isn't going to somehow negatively affect your resin 3d printer whether it's the fep sheet or the screen that's actually using for the curing lifting all that other process for your actual resin prints i really haven't seen enough conclusive evidence to say that there is negative effects and i honestly haven't done enough tests to see otherwise either but i just want to call this out that there is the potential that that could happen but again i'm really not seeing anything that negative with any of the print results that i've seen on any of the machines that i'm using today so if you want to try this out for yourself take your existing settings and bump them up to 180 and run a test print that's exactly what i'm going to be doing here today with you guys and checking out the results and then you can up that even further to 240 and see how that actually performs depending on the machine and if you're going to need g-code changes or firmware changes for those machines you'll know because typically you won't see that significant of a print speed improvement when modifying those times increasing them even further i have also seen some folks over on the facebook groups that have modified their g-codes further for the elgumar's machines that will enable them to print up to 300 or even beyond that which is pretty wild i haven't even bothered testing any of that as well also a huge shout out to ian stayner over on the elgoo mars facebook group who created this beautifully translated easy to understand g-code file that if you're interested in seeing what settings were changed to get this to work on the mars 2 pro you'll be able to easily digest and understand that there that was basically what i used as my baseline for a lot of the settings that i modified for my machine i can also say that i was able to safely update the firmware on all of my machines and downgrade them back to the original firmware which you can get directly off of elgoo's site and again depending on the resin machine that you're working with you might not need to do any of this and it's always good way for you to test out using the settings that i mentioned before to see if those impact it or not if you need to make any of these g-code changes for the g-code changes you can see here in the text file editor that i've opened up the g-code file in you're going to be looking for two entries in there m8028 which typically has a setting of s2 or s3 or some variable of that and you want to update that to s4 the next setting you're going to be looking for is m8 m8016 this typically has a setting of p315 or p25 and you're going to be changing this to p4 and again the firmware code changes that i'm going to be linking to are directly for the mars mars 2 pro and the saturn if you're interested in making any of these changes those codes should also be universal for other resin 3d printers not just the elgoo mars printers but again i haven't really tested those out on any of the other machines so a little caution goes a long way or make sure to check out some of the other facebook groups or that atlas discord channel that i was mentioning before for more details or impacts that you might run into so let's talk about some of the tests that i ran and the results that i saw on the different machines first up i ran some tests on the standard elgu mars this is the my mini factory edition which is why you're seeing it in the green casing here and the green trim it's really nice beginner resin 3d printer the standard mars doesn't have a mono screen or anything fancy like that so i was not expecting to see amazing results but maybe some uh simple results here with making those changes i also used for a lot of the test prints the amera labs testing print file here that i'll have links down below if you're interested in running one of these in general this is about an hour print give or take what settings you're running with and what machine so it's just a quick little test print that you're able to work with another thing that i went off and did is printed these pre g code changes and post g code changes to see what kind of test results i might see with these machines so for the regular elgu mars with my standard profile for the elgoo abs-like gray resin i was seeing print times of 1 hour and 17 minutes for my first test print and again this is all the pre-g code changing i then updated my lift settings to 180 and saw a print time of 1 hour and 9 minutes i then further changed the lift settings to 240 and saw a print time of 1 hour and 4 minutes and again all of the prints i think look pretty decent for the results with those setting changes and funny enough it was actually one minute longer at one hour and five minutes so changing the g-code on the standard mars i didn't really see that significant of a an increase in the print time by modifying the g-code so maybe it wasn't really even necessary to do that for the test file that i went off and run since i saw decent results with those print setting changes at 240 i decided to run off and print this darth maul bust which was a five hour and seven minute print at that 240 lift speed the results were okay uh not the greatest i definitely see some layer shifts in there and in fact this was actually the second print with this because the first one failed completely and i don't know if that was an issue with just me slicing it and maybe not having it properly supported but it looked like a pancake when it first printed so i went off and basically re-supported it re-sliced it and it printed but again it wasn't exactly great the next set of test prints that i did were with the mars 2 pro this is a mono screen resin 3d printer very similar to the original mars just with some really nice upgrades applied to it i'd get some ridiculously nice prints off of this machine and would highly recommend it to just about anyone out there that's interested in getting started with a resin 3d printer so i did the same set of amer lab test prints with the mars 2 pro and here are the results that i saw with the pre-g code changes in my standard profile i had a 53 minute print at 180 lift speed i had a 47 minute print and at 240 lift speed i had a 44 minute print that is a pretty nice savings there for these mono screen printers that's uh i'm pretty pretty happy with that and again the results looked pretty good as well it's a lot of pretty i've got to stop saying that and then oddly enough i went off and changed the g code changed those settings and ran those test prints again and got the exact same results so i really did not see any benefit from modifying the g-code on the mars 2 pro i am sure folks out there will argue with me about this but that's what i was seeing and maybe i did something wrong other than there are some nice additional changes that ian steiner made with his g-code modifications with disabling the fan when it's not printing which is always nice and there might have been some other changes in there as well but i really wasn't seeing any significant time savings with the settings that i plugged in again those same setting changes pre-g code versus after g code change all right now here is where things get really fun so that was just test prints and on the original mars i wasn't getting that good of results with the uh the darth maul bust so i went off and printed these geisha robot prints from ghost in the shell that were created by the creature armory which is pretty much all the files that i'm showing off in today's video it's from the creature armory and his patreon i'll have links down below to this patreon and it is a fantastic patreon with some absolutely stunning files that you should be able to run off in print and these were pre-supported as well which is incredible yeah i ran three of these you guessed it at the three different settings my standard reticent settings the 180 and the 240 and i saw like fantastic results across the board for all of them i mean honestly i'm having a hard time seeing if one really printed better than the other and i really can't tell maybe i'm just missing it but it's they all look really good oh my gosh i'm so excited about this especially that 240 setting option because it is a pretty nice time savings so with my original resin settings for the mars 2 pro it printed at almost exactly five hours so not bad for a print of this size but as soon as i bumped up the lift speed to 180 i saw that print time drop down to 4 hours and 15 minutes and then when i bumped it up even further to the 240 settings i saw the print time decrease even further at 3 hours and 55 minutes so i would honestly if you have a mars 2 pro you definitely need to at least try out don't forget the g-code changes just try out with a few test files running it at a little bit of a higher lift speed start off at that 180 and see how it goes it's once you get going with this i can't imagine now going back to the slower print speeds especially on this machine where i'm getting such great results on these prints one other thing i wanted to call out with the geisha prints here on the mars ii pro on all of the print settings that i ran with this on the three i did not have any issues with failed supports anything disconnecting or just in general print fails whatsoever they all printed perfectly the first time each time so very very happy with the results so far on this one so then i had to run off and do a bunch of prints with the elgoo saturn this is a significantly larger resin 3d printer it's a really good mid-size resin 3d printer that has a mono screen so you can anticipate to being able to print faster than your standard mars it's kind of on par with the mars 2 pro i also ran the same set of resin test prints with the ameralabs file pre g-code change with my standard resin settings the first print was a 55-hour print updating the lift speed to 180 i saw that time dropped slightly to 51 minutes and then changing it to 240 we saw it decrease even further to 48 minutes i then modified the g-code on the saturn and then re-ran that last test print at 240 lift speed and did see a further time savings of two minutes so it came out to 46 minutes in total for that test print after making the g code change and setting it to 240. so with that in place i ran off and utilized that full big build plate to do a nice big quick test print and it came out okay it was a 5 hour and 32 minute print and i had a decent number of print fails with that initial print so i wasn't exactly thrilled with the results that i saw there and i thought i could probably get better results by either slowing down the lift speed or further looking at my supports that were applied to the prints again all these files were pre-supported and i think they were just kind of breaking away with that increased lift speed so i went in and applied some more heavy supports to those one other thing that i saw with this is i'm thinking my build plate might have been just slightly loose and not as tight as it should be and i saw some wobbling and you know i don't know how to say it other than wobbling in the actual prints and in the support settings i'll try to get some close-ups so you can see that there in better detail on these prints so i then decided to do the same set of files after modifying them slightly with some additional heavy supports at the 180 lift speed and that turned out pretty much perfect i think all those prints printed successfully and everything looks super clean and crisp on all those prints and i should mention it was a 5 hour and 46 minute print with the 180 print in place i decided you know what i need to rerun this again like the geisha one at the original settings so forget the lift speed increase i want to see what this would be like if i didn't modify the lift speed and just printed these as is with my typical resin settings and that came out to 6 hours and 25 minutes and as expected all the prints looked good but it was at the cost of about 40 minutes of additional print time compared to the 180 lift speed prints and with all that in place i decided you know what i really need to try the 240 lift speed again so i re-ran the prince and they almost all printed successfully oh it was so close so close i had one print failure out of everything on the build plate again i need to maybe re-look at the support settings i think that maybe is what it came down to is that just that particular file needed some a few extra supports to really be able to maintain that 240 print speed and that print time was 5 hours and 34 minutes and one other last print that i decided to do last minute over the past few days was a file from ian roberts who has made this darth grogu file i printed this on the mars 2 pro at the 240 lift speed settings in sierra tech fast creamy resin i just wanted to try a different resin just to see how it might hold up as well with this and everything printed great with this and it was only a i think a three and a half hour long print so really fantastic to be able to see this printing so quickly so if you're interested in more details about the vroom settings for your resin 3d printers i'll have links down below to the g-code files that i used for my printers that are over on the elbow facebook group i'll also be linking to a file that i've created that has a just a quick cheat sheet of the file settings that i've changed in my resin 3d printers for this as well as i'll have links to the atlas discord group which again was a huge help for me to be able to better understand this whole thing and compile this video for you all today again sort of go out this at your own risk i can't guarantee that this won't have any sort of negative effects on the lifespan of your your display screens that you're using for your printers or the feb sheets but it is pretty cool to see a new alternative out there for being able to print faster and even being able to in theory print faster than this i've definitely seen folks over on some of those ogre groups saying that they're printing at 300 which is just kind of crazy i'll have to test that out and see if it's even possible on some of these and again for the most part i did see better results on the mono screen printers it doesn't mean it won't work on the standard resin 3d printers i was just seeing better results here on the saturn and the mars 2 pro hey hopefully you guys enjoyed this sorry it was such a long one but there's a lot of information here to throw out to you guys hopefully you enjoyed make sure to check out the links here for creature armory the amazing pre-supported files there as well huge thank you to elgoo for sponsoring today's video and a huge thank you to my patreon supporters for your continued support if you're interested in finding out more about my patreon you'll find links down below also if you're interested in any of those elegu products i'll have links down below where you can find links to the machines and the saturn is becoming more and more available over on amazon which is really exciting some of those links might be affiliate links thanks again for watching guys and i'll see you next time bye now [Music]
