Fdm Vs Sla 3d Printed Bolts And Nuts (pla Vs Resin)


[MUSIC] [Applause]. Hello, welcome to my tech fun. Few months ago, I created a video that I was testing optimal positions for 3d printing bolts and screw nuts. And then I’d get a lot of comments to ER. I should test different materials like ptg’s much better. Only ABS or nylon can be used for these purposes that will be tested too. But now in this video, I am testing fdn3d printed bolts and screw nuts versus SLA silic bolts and nuts. The this is the most common material, which is the PLA. And, of course, versus resin. I got a lot of question. Why to 3d print bolts first? My my first imagination was to do this test to see. What is the optimal printing position for trees themselves, which may be part of your object? But then I got very interesting comments that somebody are actually using these non-metallic boards. They are used in electricity and also a very interesting comment. I got that somebody really use these plastic bolts with the toilet because it will not scratch the ceramic. Since I don’t have SLS in the printer, I use a printing service. These are m6 by 20 millimeter bolts and also m6 nuts for six six pieces. I paid nineteen dollars. I get two extra pieces from each, and so you must understand why I don’t have so many test probes only two per test since I don’t have any experience with SLA 3d printed parts. I would like to analyze these resin bolts and screw nuts, And, of course, first thing is to check if I can screw on the knot to the board, and I notice it’s, uh, it’s on, but at the end, it stops, and then I analyze it a little bit better, and I find out that the reason is so-called elephant foot where the object is attached to the bed. It’s a little bit bigger just to be sure, if really, that’s the problem. The metallic nut should go on raising bolt and, yes, it’s on it and raising nuts shouldn’t go completely on a metallic board, And, of course, I also tried the PLA nuts and it’s also very tight, but they goes on to on boards so inside on inner thread. I can solve this problem with the m6 step tool, and I can clear the tree holding it in my hand, so I don’t even need the rise. But outside it is still a problem because it doesn’t go into the branch and the same problem I have with the boards. I check the dimensions of this flat surface and it’s approximately 10.1 millimeters, but on edge it’s approximately 10.45 so it’s too big to go inside the branch on metallic balls. This dimension is approximately 9.8 5.9 millimeters and on pla board. Its 10.1 millimeter, but they go into range without a problem, so this problem can be solved with the same paper or fire tool on those edges. Sandpaper is a little bit better better because you don’t have to clear the the file at the end of the work and resin bolts are now almost ready to use and just in case I’m cleaning them with the die tool, and then I notice that outer diameter of the boat is reduced from 5.9 to 5.8 millimeters, so I they reduced by 0.1 millimeter. In theory, They should be six millimeters, but this dimension is always in minus of tolerance and, for example on metallic balls. This dimension is 5.75 millimeters. Okay, next is to analyze the pla bolts and screw nuts. Both are printed in horizontal position because they are much stronger, but there is a problem with the surface quality, so those support marks are still there and they are very visible and not even metallic ball. Nuts can go on these walls now. But key to this problem is the m6 die tool, so cleaning is very easy. I can do it again holding in my hand without using a vise and after cleaning the thread, all three types of the nuts can be screwed to the board, and they go on it very easily. PDA, screw nuts are printed in horizontal position. This means the thread is in vertical position and they’re almost ready to use straight from the 3d printer, But just in case I cleaned the trade with the n6 step tool to have the same dimensions on all used screwnuts and now it’s time for testing. So let’s break some plastic. This is my testing setup. Want on chain hose but weaker point. Is this crane scale which is 500 kilograms? And I can attach here the other side. I can measure up to 500 kilograms. That’s the limit of this setup. [MUSIC] [Music] [Music] broke here, but not sure. I have to take this out. Somehow it’s not tight. I can turn it from the other side. [MUSIC] SLA boat [Music] broke where the head was. [MUSIC] broke here where the head is [Music] [Music] [Music] as planet broken three pieces [Music] resin, both share stress number one [Music] a similar break. Four pieces it explodes. Actually, this is my new setup for torque test wise. This will be only a washer and a 40 kilogram hanging scale and open-end wrench pillar ball, torque test one. So PLA bolt is in combination with metallic nut. I’m rotating it until I reach the ultimate strength, The maximum torque and then something breaks and then it starts reducing so this maximal value. I’m recording for comparison so [Music] resin [Music] too brittle broke too suddenly. [MUSIC] Same story both broke huge difference on this test so here the treat was shared, but it was still on it and here we the resin boards. They broke very suddenly so theoretically, the PLA is very brittle material, but even it, uh, performed much better than the resin. Bots here, so next test with the Pele screw nut. And this hole is same size as a washer for m6 So I don’t need a washer here. [MUSIC] pull out the treats [Music] and again three pull downs and now it’s time to test the [Music] resin interesting. It broke in a cross section. [MUSIC] This time the trade is shared out. Now I’m a little confused because I already did tests with the PLA m6 screw nuts and they broke under maybe 70 kilograms or something like that, then analyze. What is the difference and the biggest difference? Is this hole here, new setup? It is 6.5 millimeters and on my previous setup. It is 7.2 millimeters approximately. It looks like this has so big effect because everything else should be the same, but anyway. This is only cooperation test. So setup is same for these two materials and here. The plastic nut is used in combination with metallic bolt and again I’m rotating until it reached the ultimate strength, so the maximum torque value something breaks and when it starts reducing, I’m recording that maximum values for compression. I think the trade is shared now. Doesn’t look bad. It’s damaged a little bit the trade, but it looks good. [music] okay. I think now the trade is damaged. Not bad, actually. [MUSIC] And now resin not test number one [Music] wow [Music] in the same way, so they broke on the same way and very interesting. The p-line nuts are almost usable even now after some tree damaging in this page, I summarize our results since I have two tests per each type with the red. I’m calculating the average values and for cooperation. Uh, in this table, you can see Pele and resin in percentage and here on this graph you can see visually. What is the difference for each test between PLA and resid? These are average values the conclusions. Well, you saw the number. But beside those values, there are other things I’m not sure. Can it be seen on camera? And that’s the feeling this resin was very brittle. It breaks too suddenly compared to the PLA. Actually, I feel that the vermin it will break. I thought PLA is more brittle compared to the petg, but but I’m sure there are other types of the resin. Maybe you can give me some suggestions in comments, but this tested object was very brittle. It breaks very subtle without any warnings. This resin object was printed in vertical position. Uh, everybody on you. Internet is telling that here the orientation doesn’t matter, but the company I ordered, uh, these bolts. They told me maybe they have a feeling that there is some differences, so that will be tested in my next video, but now let’s pronounce the today’s winner so winner of this competition today. Is Billy. Sorry about that. Actually, I wasn’t sure about the result before I started this. Uh, experiment and also I’m very curious. What will be the result between injection molded and PLA boat that will be tested too in near future? Thank you for watching and happy printing bye.
