FDM vs SLA 3D printed bolts and nuts (PLA vs Resin)
HTML-код
- Опубликовано: 15 июл 2024
- What do you think, which is stronger? FDM printed (PLA) or SLA printed (Resin) bolt and screw nut? That's what I am testing in this video. Strengh test of PLA bolt as most common material for FDM 3D printer and Water Washable Photopolymer resin. Since I don't have SLA 3D printer, I used 3D printing service, I ordered resin M6x20 bolts and M6 nuts.

This is actually an incredibly professional and scientific approach, I'm very impressed. I did not expect such a high quality experiment.
Yep. It's really very professional to compare the hardness along the layers for sla and across the layers for fdm😂
Thank you for doing these tests. I remember about a year ago your other video on PDM strength bolts/nuts really helped me too.
thanks, and there will be more, I am going deeper into different material testings..
I believe the most common SLA resins are just for show, not strength, though I do believe you can get resins that are stronger. Some commercial resins are hard like a really dense and smooth concrete. :) If you end up experimenting with stronger resins it would be cool to see PLA+ or other strong versions. I love your tests, keep up the great work!
@Dev Guy I use high strength resins on my personal Formlabs form 3 3d printer to get high-quality prototypes. I think you can use good resins without a commercial 3d printer to get very strong parts. I also use all kinds of commercial elastic resins for unique parts.
@Dev Guy I use an automated wash and cure system to make the process easier and faster. The price of Formlabs official resins is also quite absurd so I modified one of their empty cartridges with a small part from Protoart and now I can use that cartridge with any third-party material and refill it whenever I run out. I usually like to buy from ApplyLabWork whose materials are half the price of Formlabs resin.
You should try the dental resins the are made to stand up to chewing for years. They are also cured for 20 min at 66C.
Oh is this true cus I was thinking of getting a resin printer but I’ve been seeing how weak they are and I need them to a be abit strong should I still gets resin , input would be much appreciated!
The water washable resins are very brittle, especially compared to the stronger types. The only other type I've used is Siraya's ABS-like resin and it's much tougher, i'm considering trying it for functional parts.
There are tons of resin formulas, for conductivity, strength, flexibility and other material properties. I've also read many posts where people have mixed resins to a achieve a blend of material properties.
You have done a very nice job of comparing the two materials with quantitative analysis. I'm impressed. I love your hoist setup to test tensile strength. Then you did a very nice job of gathering all the information into the spreadsheet for quick comparison of the data. You put a lot of time and effort into making the setup for the tests. I make and post videos under another account (which is why you won't find any videos associated with this account) and nothing I do is nearly as good as what you've done here. Thank you for the time and effort to make and post this video. I am considering purchasing a 3D printer and this information was very helpful to me in trying to choose between FDM and resin printing.
Thanks for your tests! The info is really helpful to eyeball the plastic details strength.
how wonderful.. a great backyard test with real equations and instrumentation values... this makes choosing the plastic much more logical... thanks a lot...:)
Great video! It was exactly what I was looking for.
This is amazing! Thanks for posting this!
this is the first video of yours that I have watched, and I want to say that I loved it. Thank you so much for the information - it was very useful. I will be subscribing to your channel
I've been enjoying your content and forgot to subscribe, I've rectified this now.
Keep up the great work, you have provided a lot of valuable information.
Man i liked too much your way to deliver real engineering and practical usage of learning.
I've also laught a lot at the end with the
octagon winner! hahahaha
Definitely a good channel to follow up!
Best regards from brazil!
Thank you for the detailed tests!
Very interesting test.I simply could not imagine PLA screws having this strength.
Me acabo de terminar de ver varios de tus videos, me encantan las pruebas que hacer. Sigue asi!(I just finished watching several of your videos, I love the tests to do. Keep it up!)
excellent video, thanks for sharing those tests.
Thank you, Sir! I was surprised by the results. Good job!
Thank you, and don't forget to check second and third round too ruclips.net/video/7r16-UDo2t4/видео.html
Very interesting test. Thanks for sharing!
Great testing!
Amazing video! I love the comparison and the method. A lot of great tips here too.
Love your videos, very in depth
Great video, good job comparing them.
Thank you for the tests !
One of the best videos on youtube
nice job. Perfect comparation. This was what i was loking for.
Thx. There are two more similar tests with stronger resin vs petg and vs abs
love it. Ive seen many tests of all those special tough resins but its hard to find tests of just plain normal resin
amazing testing! Thanks
Interesting comparison. well done
Perfect test, thank you
Exactly what I was looking for!! Thank you very much!
Soon I will compare a stronger resin too (Siraya Blu).
I love your videos, i learn a lot
Thank you - this was very informative!
Absolutely fantastic and informative video. Just subscribed!
There is a 2nd match too: Siraya vs PETG. ruclips.net/video/7r16-UDo2t4/видео.html
Thanks for sharing this fun competition video my friend! Really enjoy watching & really helps us to choose better material. Great work on every test result. Liked & subbed! Hope to see more of your work😁👍🏼👍🏼👍🏼
Thank you. Here is another similar video: ruclips.net/video/7r16-UDo2t4/видео.html
@@MyTechFun Welcome & keep come your great work my friend. We try to leard how to make our own rc part. Please do come by to our channel too. We do video about rc cars😁👍🏼
Great video, thank you for sharing!
Great test
Thanks for sharing :-)
great work!!!
Thank you for this... It gives me a clear idea when to use what material
Check my other two videos filament vs resin. Very interesting and different results there
I have been a bit jealous of the nice details of the resin printers, but as most of my projects are functional and not only esthetic I’m happy I choose a FDM one. Thanks for sharing 👍🏻
Check details of 0.2mm nozzle in this video, very similar to SLA (the 50% benchy part in video starting from 19:39)
very nice testing, good engineering, this is how a real reviewing and testing should be done. respect!
Thank you this was very helpful
thanks for this very informative video sir.
WOW - thanks. I like tests like this and it's great that you have a summary page.
I look forward to seeing the future tests you do. I subscribed to your channel.
I am surprised they have elephant foot. A service that prints things should know that you print these things off the build plate and use supports. They should have been printed at an angle too. You really need to retest with a better resin print. I hope you have time to do that. (Assuming you already haven't.)
Great content, thank you
Very interesting results. I would have never thought that resin was so brittle.
Not every resin. But this budget resin, yes. (there are other similar tests, with different results, mostly with Siraya resins)
excellent presentation simple logical and very intuitive.
Very interesting video.
Thank you
Nice and profi test. I like metodics :)
Great video!!
Thank you very much for this tests.
You are welcome! And there are several videos on this topic: www.mytechfun.com/videos/fdm_vs_sla
Thank you. These videos are usefull for me.
Great job, thanks.
Very GOOD video!
Thanks for sharing!!
Nice video. Was really wondering this myself. I like your new test setup, though i miss seeing you dangle from the PLA bolts.
Thanks, belive it or not, I am missing that dangle too, it was more fun to me :-)
You could try "tough resins" and it would be interesting to see the performance of enhanced PLAs like PLA 870.
someting like formlabs tough syriya blu/clear v2
And then compare the cost , $$...
@@mikhaelchernogorsky556 The tough resin won't work better for this - it'll likely be worse. It's tougher against impact at the expense of tensile strength and dimensional stability under load. Ironically, the standard resin has among the highest tensile strength.
@@christopherkemsley4758 so if I want to print some mount or joint that will carry a weight on it it is better to use strong PLA materials like nylon rather than tough resin?
@@christopherkemsley4758 Interesting. Theres a video of these withstanding 90 ft lbs on a torque wrench.
Nice tests and not surprising. What I got from this video is that if I need a bolt with good tensile and shear strength, I should use a metal one. 😂😝
Great great video very usefull info.
That certainly defied my expectations; not having much experience with either, I assumed the resin would have been much stronger.
These were budget materials. There is a 2nd match (Siraya vs PETG) ruclips.net/video/7r16-UDo2t4/видео.html
Great job of stress testing and backing up evidences with spreadsheets. Also the used of video evidence is helpful. Sounds like fdm augmented with other materials can exceed the current capabilities of resin. Now if resin or sla can be augmented that would provide additional capability that is not currently available. Thanks again.
There is a 2nd match too: ruclips.net/video/7r16-UDo2t4/видео.html
Great job, thank you from Siberia!
I solved the elephants food on my resin printer (Anycubic) by lowering the exposure of the first layer. All resins are different so you'll need to figure this out by trial and error. And for the tight nut threads, I adjusted the tolerances on Chitubox by trial and error. My nuts and bolts fit perfectly straight out of the print and also fit their matching metal fasteners no problem. I just print them standing up with no supports too. Hope that helps anyone.
I'm wondering if it is possible to print sealed structures from flexible resin?
I don't have experience with flexible resin so far.
Would be nice if you tested “tough resin”. There is also a optimal printing tempts for sla. I believe it to be 30c at least.
great vid. thanks and keep it up.
There are several versions of this video (better materials)
@@MyTechFun That's amezing, thanks
Very informative. thank you
Very welcome. There is a 2nd match too (Siraya Blu vs PETG): ruclips.net/video/7r16-UDo2t4/видео.html
Wow!!!! And I was thinking to go Resin printer, but not for what I make as they need to be tough. thankyou very much
Take a look of the second part, Siraya Blu vs PETG. Also Tenacious resin test is in progress..
Thank you
Resins are great for modeling but not for practical use like FDM printers. That was what I found in my research before purchasing my 3D printer. Thank you for this, as this helps many of us know the limitations of PLA prints without spending the time on the research. Keep up the great work/videos!
I got Siraya Blu resin for testing, it should be much stronger.. there will be round 2 for this video soon ;-)
Thanks!
Also keep in mind that resin also has layer lines what weaken it so those should have been printed in same format as pla bolts however I still think resign is going to be weaker by far it’s just to brittle needs to be abs like resin or a tough resin.
nice video
Nice video and great testing but as you also hinted to at the end there is a big problem with the comparability here. On the one side is PLA and while there are also many types here, that is a specific material. On the other side you just have a generic resin that is not intended to be used in physically demanding tasks. Of course there is a point here, that the cheapest material for FDM (pla) is much stronger than cheap resin but that is just the way it is. Resin printers exist in the first place because of the great quality and accuracy. If you want high performance in SLA you need to get specialized resin, just as you would get specialized filament for FDM if you wanted to get the best possible quality prints.
Yes, this is just test about regular PLA and Resin. I ordered these resin bolts, and of course, company created it using most popular (probably economic) material.
nice comment and video 👍
its fun and i enjoy the video
I use Siraya Tech resins and get great results with strength. I mix my own resins with combos of Tenacious and Elegoo, Sculpt, Build, and a few others. Strength can be obtained with SLA, it just takes some playing around. And orientation DOES matter, you still have layers. Great video though, thanks!
Hell yea Ill like your video!!!
i had no idea small pla bolts would be so tuff i was surprised.
I have seen actual fibre core strand carbon, kevlar or fibreglass filament. I can't see how it would stop and start though without a cutter at head to allow breaks. Impressive tests! pla is tougher than thought. I just got me a Anycube X as treat for lockdown cabin fever. LOL!
would be nice to see tough resin tests not standard resin we know this is very brittle already bu tthank you all the same for the time and effort my good sir.
Other resin will be tested too. Siraya Blu for example.
Great video.
*Recommendation:*
You have to use larger step size as it is too small from plastic.
Thanks
I had to replace a kitchen sink screw few years ago with a printed one. The PLA one hold up the job for few weeks until boiling water was drained. Next one I printed in ABS and 3 years later it is still going strong, no leak no problem with boiling water being drained.
BTW I had to print this bolt nut combination as the sink was old and no spare parts were available.
Is it resin or fdm?
@@Thatguy-jh2ex fdm print
@@3dgussner958 do you prefer fdm or resin? And which printer would be stronger? For printing car interior parts...? And it has to be in high detail aswell
@@Thatguy-jh2ex I don't have a resin printer and can't say if there's any resin that withstand the heat in a car. Also these have often small build volumes, so depending on the object you want to print.
Abs and asa aren't easy to print but holding up the high temperatures.
It would be interesting to see if they undergo compression test, and metal cutting to go against shear, bending, compression, and friction.
Tests are resonably sound for typical uses, but materials are questionable. Another couple of parameters are required. But gives us some idea. Thank you for sharing.
Very interesting, thanks for that.
I'd like to have seen the steel components tested as well for perspective.
I'd never have considered it before, but 3D printing might be a suitable source for obscure thread patterns in non critical applications.
Good idea, now I am curious too. Only I have to make my testing equipment stronger than those metallic bolts..
@@MyTechFun A (grade 5) 1/4" bolt has 2700 lb/f (Coarse thread) and 3100 lb/f (Fine thread) proof load. One just need to check the specs of those bolts, it is usualy specified. From The Engineering ToolBox site.
Proof Load - is the maximum tensile force that can be applied to a bolt that will not result in plastic deformation.
This is nuts
V good sir
Nice experiment for practical printing. Some tough resin and ASA printed parts would be good for comparison.
Thanks for suggestion. When I will have my own SLA 3D printer, I will test a lot of different materials.
Amazing video as per ushe. Looking forward to cooperate with you again!
Print orientation matters on SLA too, it would have never popped of the head if it was printed through the lenght
Came here to see if anyone mentioned this, and if someone mentioned tough resins. Tech community didn't disappoint.
SLA orientation has been already tested ruclips.net/video/E7XDMzGb5WI/видео.html
Tough resin too (BLU) and tenacious test is in progress. ruclips.net/video/7r16-UDo2t4/видео.html
We see lots of our users recommending our Blu and Tenacious resins. We are happy to supply if you are interested to test it out. I believe it would give PLA and PETG a serious run for their money
I got your email. I'll reply soon
Could you maybe test the high end resin from formlabs with your sla printer? Formlabs says that their resin is strong enough like Pa6. You can also use the resin with elegoo or anycubic dlp printer because both printer are still working with 405nm light wave.
Very good engineering video. I think resin its better for models or pieces that doesn't need mechanical strength because you can print almost finished parts. FDM it's cheaper and much more faster to print and much stronger
Nagyon jó teszt volt, kezdem megbánni, hogy SLA nyomtatót vettem mérnöki felhasználásra...
Nemsokára lesz round 2, kaptam tech resin-t tesztelésre. Siyara Blu. És itt nem beszéltem a hőállóságról
Ha tudsz időt szakìtani rà, az igen jò volna, èn elsősorban prototìpus fröccsöntőformakat nyomtatnèk, de a standard gyanta nem alkalmas rà, fdm technològia pedig vègkèpp
Excellent video ! two thumbs up ! I have one request , can you include the weight of the fasteners and show the relative strength to weight ratios .
Resin M6x20 is 0.992 g and PLA bolt is 1.015 g
@@MyTechFun Thank you
nice consistent setup. Please print the resin screws and nuts horizontally next time so that the layers are stable like with PLA. thank you.
Resin once cured is a lot more brittle than PLA.
PLA on the other hand don't take static stress over time as well as resin does. It permanently deforms after a while where resiin will stay in shape.
There is a second match: ruclips.net/video/7r16-UDo2t4/видео.html
I came here already knowing the answer. lol But I wanted to know just how brittle resin is. lol Thank's for the breakdown.
What I expected. I've used epoxy resin a lot and while it is awesome when combined with glass or carbon fibres, on its own it's very weak.
well epoxy and printer resin are kinda not the same thing. i was thinking of dipping my prints into epoxy for strength and that crystal clear protective layer but not sure if it helps
I suscribe just for the last boxing joke its funny
Resin just smooth
i think the reason why pla is stronger than resin is because of the way the material was made. PLA is extruded in a mesh like pattern while resin is made whole. If we look at it as rope vs a single thread "WITH THE SAME THICKNESS" emphasis on same thickness, the rope would win because of the gaps and twining. the gaps and twining of the rope does a better job of dispersing force like a sponge, whereas a whole material doesn't. Another example is how folded iron is stronger than molded iron. this is due to the grain structure hold it together.
