Using an impact force test,
example = using a hammer on the object.
PLA will break/shatter quite easily while ABS is much more stronger and harder to shatter/break.
This is because PLA is more brittle.
If you wanted to do a proper test, you should do another video that involves smashing the object with a hammer.
The is more like how the quadcopter would be in real life, from an impact force
Doing the bend test involves continuous bend force over a longer period of time.
This is does not match real life scenario of the quad copter getting an impact force
which is a different force to the bend force.
Impact force is a power force over a shorter period of time (ie helicopter crash, hammer smash)
Tyler Durden he said that at the end
i will print mine at 150% infill. it will be stong
😂
You have to use binary integers for best performance so you need to use 256% infill for even stronger prints.
@@teresashinkansen9402 i know it's a joke, but i think all parameters should be a multiple of layer height/nozzle diameter
i will print mine at 300% infill. it will be very strong
I printed at 900% and it's bulletproof
hanging weights from the middle (with a heafty line) and with simply support ends would make a quantitative and repeatable test.
強度がこんなに変わるとは思いませんでした。非常に参考になりました。
Nice tests! the quad is probably the best design I've seen around that can be printed and keep both the weight down and quality up. this test got me thinking about the new filaments of pla that are roughly 20% carbon fibre and wondering if you can reduce the infill of the parts whilst maintaining durability. What do you think?
Unless they claim it's stronger than standard PLA by a great margin then probaly not worth it. In a crash the plastic material itself is the weakest part. Best we can do is print at 100% infill and limit the flying weight of the quad.
I like the addition of the close ups of the breakage. Well done as usual. What infill was the KitKat? Maybe if the infill was increased to 100% it could potentially be in the running for the quadcopter?
+jeevesme
Ha, yeah if it wasn't for the wafer inside it may have been strong enough to compete...
Chuckled on every victory "Yesss"!
why PLA is stronger than ABS? ABS is used to be extruded in one piece, that way it is damn strong and can bear a lot of heat...but since its more heat resistent, layering it will make the whole object weaker, because of the weak adhesion between the layers...PLA can make better bonding between the layers, therefore it will be stronger than ABS in FDM printing
These tests need to be more quantitative. You should make a solid frame with 2 towers that supports either end and then use a strap around the middle with a weight scale on it. when you pull, if you use one with a max pull gauge, then you can give actual numerical figures to your tests. much better.
If that's the kind of data you require why don't you print the parts and take the measurements yourself?
True. I could do that if I had a working printer to hand. But as the parts have been already made etc. I thought it would make the tests done here more useful instead of guesswork. The actual values are not important, but how much harder is a part compared to another cannot be truly stated just by "that one was tough to break". Try the same tests but with the hardest first and see what the results are. I bet there will be differences. It is not quantitative. At least with my suggestion you can say, PLA at 100% fill is 3 times as tough as ABS at 50% or something similar. Far more useful. I am just trying to help, this sort of information could put send the web blog viral. But if you want me to make the same parts and do the quantitative tests and score a viral video then sure thing.
Even though the first half of the video assumpted PLA would be the right material your assumption is absolutely right. If the material has to withstand a short massive impact like crash or something it has to be flexible like ABS. You may also try some Polypropylene as used to seal bath tiles. It has a a very low glas transition temperature though is more flexible than ABS and has for me best seen layer adheason. It is awesomely strong.
+Klaus Daume
Thanks for your comment. Regarding Polypropylene is there a filament made of this material? Checkout my other video on Nylon Alloy 910 - that stuff is amazing!
+Tech2C I did read ones that there is a filament with pp but I used a spool used in extruders for professional bath tile sealing. unfortunately I only know the German word (Schweißextruder) but can't tell about the right translation. in terms of nylon I print trimmer line of weed wackers. Nylon is indeed awesome in strength as well but pp didn't warp as much.
just wondering
wouldnt a pattern like the flamewheel one be much stronger than this ladder style pattern?
Did you try PETG in a flight test? How was the experience?
+PlastiMaker
Nah I didn't. I basically started designing the new frame and continued down that path.
I love you m8.
Lol, thx !
all this and no torque wrench or anything?
noozle dimension?=)
And all this time I thought abs was stronger....
you have 666 likes strange
Come on that's not a fair comparison. You should have tested with higher quality chocolate, plus the infill was way less than 50%.
lol :)
So PLA is Stronger, but ABS has more flex to it. Is there any plastic with both characteristics?
PMS, in fact it has many characteristics.. ;)
Troy Dawson i have tried for years to break that... tought stuff. Def doesnt go with the laws of physics. Able to offload stess to adjacent objects.
wow, i thought the abs should be stronger than pla ...
PLA is more brittle, meaning cracks propagates easily. On the other hand ABS will deform until it finally cracks. You can see that for example by bending a filament for each type of material.
kind of like how low carbon steel is more brittle than high carbon steel. But in the case of 3D printing, PLA gets a bad rep even though it's actually quite strong for most things. But the main difference is temperature stability. PLA will melt in your car on a hot day, ABS won't.
Abs has a higher impact strength which is more important in a drone frame
In the name of science, this has the best ending compared to other videos I have watched!
I always used to think that 3d printed parts were quite delicate and fragile. This has definitely proved otherwise.
Love this video!, you looks sacrifice hand(without gloves) so that viewers can see how strong you are trying to bend the both materials. Thanks for that!
But lot of people said ABS is more durable then the PLA, is that true? I know durable and strong is different, but they both are interconnected/related. Thanks for anyone answer..
The PLA 50% test is probably invalid, it broke right through a support structure rather than thrugh a corner. The stresses involved spread very differently in the material compared to the other tests. Could you redo that one test? It seems very unlikely to me that it would naturally crack along that path.
a different type of infill would make the 50% stronger
would you care to elaborate?
Is there a way to honeycomb infill? That is the only technique I know of to preserve some of the strength when infilling, but I doubt it would be very effective with ABS, but would be with PLA.
Richard Smith you can do honey comb infills. It varies from slicer to slicer, but different slicers offer different infill options. I believe you can use mesh mixer to create custom imfills.
Excellent comparison test. I would have thought that the ABS would have been allot stronger than the PLA.
Looks like the PLA is brittle compared to the ABS?
Agree that the ABS printed 100% is your best choice for the Quad Copter Arms..
What name brand Filaments are these test artificials printed in?
What speed did you print them at?
Thanks again for the video.
Cheers
Willy
Nice video PLA is stronger than ABS many people have proved this. With your parts you should try treat them to get even stronger layer bonding. Put the PLA part in a water bath around 50*-60* getting it to bond the layers better. ABS will take higher temps also a acetone weld strength test on your parts. All 3d printed parts can benefit from this heat treated bonding process.
is the peon your design? i printed it this week in CF petg and it looks verz strong and the look of the parts is awesome, get in touch if you want we could talk about that
Huge props to you, good sir! VERY, very handy comparison of all the major printing materials out there. I searched for hours on the web, and stumbled across your formidable content by pure accident. Thanks a lot for all your experiments and effort!
*goes of and buys a spool of PETG*
+docpayce1
Thanks for your support! It was surprising to see all the differences between the materials. And yes, PETG is my go-to filament now too... :)
If your going to do a stress test? set it up as a real stress test NOT hand bending test!! we want good numbers not grunting.
Remember that is the orientation of the print thats makes them more strong , all of this shapes are simple extrusion forms , the best for that test
Awesome, thanks for sharing.
Im really surprised, I thought ABS was all over it with strength compared to PLA.. *me goes and pulls the PLA filament out of the old printer now :D
The issue is that there are two types of *strength* in material science, tensile strength and impact strength. PLA has a higher tensile strength whilst ABS has a higher impact strength (i.e. "tougher"). In other words, PLA is "stronger" under static loads whilst ABS is stronger under highly dynamic loads (i.e. "tougher"). Tougher materials have greater impact resistance and this is due to the fact that it strikes a good balance between tensile strength and ductility. The tensile strength of PLA is indeed higher than ABS, however ABS is *far* more ductile than PLA (as demonstrated by being far more flexible than PLA) and it is this higher combination of tensile strength and ductility in ABS vs PLA that makes it a "tougher" material, able to handle larger impacts than PLA.
This video only demonstrates the relative tensile strength of PLA vs ABS and tells us nothing about the relative impact strength of these two materials. Having said that, I can tell you that ABS has greater impact strength than PLA though which is why it's better to use ABS for components expected to experience impacts (e.g. quad-copter arms). You want tougher materials for quad-copter arms as they are less likely to shatter upon impacts, meaning less of the impact energy is transferred to the critical components (such as the electronics in/on the central body).
ULTRA SCIENTIFIC! Hey, where is the torque readout/display on your arm? I can't see it? Next time, you should make sure that the camera has a view of it. :)
I am obsessed with these as a test coupon. You might like Proto-pasta HTPLA v3 material. PLA strength & stiffness maintained to higher temperatures and with a bit more give before breaking. Check it out! ;-)
Now i am sure that my beyblade will gonna be strong!thank you sir for showing us this video!Godbless!!!😊🙏
Wow did not know that. I am just learning the in fill part of parting. I use a XYZ printer . I built a 6 speed PC shifter I use for a big rig game, looking to improve my design. Loved your video !
Maybe you should use scientific method?. as a dynamometer...
I'm sure it's me , but this kind of test is lacking of precision, even if we can clearly see the diference...
I like accuracy!
Anyway, I never miss any of your videos, because I learn many thing from them.
where did you buy and what brand are your Filaments? Apparently there are louds of different ones on the market and Quality-wise there are big differences.
so basically pla is stronger but very volatile or weak against heat and adbs is subpar from pla but can handle aloooot of heat and still maintain its strength.
Could you make a video about how to design this (or another) copter in a 3d environment? I've tried, but I'm really bad in this. btw, I love your videos!
I thought pla was more brittle and easier to break.
Gave an idea on deciding what filament to use for my project.thanks.
oh my god! PLA is fucking hard LOL good video
I have used PLA to built a lage quadcopter the main issue was the temperature change characteristic of a PLA , it has high shrinkage which makes screws lose
So true. A friend of mine left his PLA quadcopter in his car on a hot summer's day. It wasn't a quadcopter after that...
I'm curious how the polycarbonate compares.. Do you have the results or video for that by chance?
It would be interesting to see what kind of results you'd get mixing materials in a dual extruded setup, combining abs/pla with polycarb/nylon could give some decent results.!
That is like the best idea ever.
+Panoreth 3D Printing
Indeed. Think of samurai swords: Hard edge, soft body. You could do something similar here to distribute the stress more effectively. E.g. hard PC perimeter, 100% ABS infill. My 3D printing nerves are tingling right now.
A pretty good analogy actually :)
You HAVE to make that KitKat Drone, chocolate powered ! In the name of science !!
+Sebastien Geek
I would pay to see that!!
oh, i didn't know you already tested nylon and polycarbonate. interesting, will check it.
Is this Dave from Eevblog or do you guys just sound really similar? 😂
Thanks for this video, it totally convinced me on what to get for my projects.
How strong you need? its just 250 class, 50% strong enogh
Great! thank you for this. PLA was better then I expected.
what is the printer you are using, thnx for ur review on innfills :D
I want a Kit Kat quadcoppter.
A lil acetone will fix those abs pieces right up.
+Granite
That's the attitude :)
Nice comparison.
PLA is more brittle but its stronger
Thanks for the Peon230 model it's a ton of fun... I just uploaded a video on my channel of just cruising around with it at the park. I have broken a few arms flying so good to see this comparison as well. I did a remix on the cam mount to make it easier to mount a go-pro on there. For the most part I've been flying with PLA arms but just replaced one with a Nylon one (the nylon is much trickier to print with though, as I'm sure you know)
For the record where mine broke was always in the motor mount holes rather than on the main shaft of the arm itself.
Interesting. Thanks for the feedback!
ABS and PLA are stronger than I thought. What software do you use to edit your video and what software do you use to design 3d models in?
+Panoreth 3D Printing
Sony Vegas Pro and Cubify Design.
is ABS better than PLA?
If u used it on drones if course it will break during crash
where did you brought this pla and abs?
nice it can be fun to try make one on my 3d printer ;P
Great stuff! Thanks for this video, It was really interesting to see how resilient the two most common filament types can be when printed solid! It also highlights just how useful the exotic filaments can be when used to fit a specific purpose!
Laughed out loud at the final bonus test at the end, I also think that last material would melt fairly quickly in the aussie sun! :)
+ShiftyRed
Exaclty right. I was shocked how much extra strength we get as a solid piece. Thanks for watching :P
Great video and thank you for your help...
what filament brand are you using?
love your work! I have a suggestion/request.. can you do a series on gears? I've made a gearbox system of 2 1:1 gears for a model Plane but pla doesn't seem to be strong enough under load. the teeth shear and wear very quickly.. would be great to know if any of these other materials you have are better suited to the task. cheers
Use nylon filament. Not the cheapest, but is perfectly suited for mechanical joints and gears as such. Checkout the Taulman3D website.
+Tech2C great! thanks !! :)
also consider dropping the number of teeth on the gear to make them larger that will help a whole lot
5 or so is a good number for small gears you'll need the old trapazoid shaped teeth instead of the triangle edged teeth
break me off a piece of that Kit Kat bar.
Saved me from doing it, thanks! ;)
what program he slice it (print it )
Lovely!
Thank you for the video.
PLA is NOT stronger than ABS. EVER.
+8BitLife The stress response is different. PLA fails instantly while ABS will flex before it fails. The amount of force necessary proofs the opposite of your statement.
No it doesn't.
LOL PLA is stronger than the ABS
Very interesting.
I thought that ABS was stronger than PLA, can some one explain?
Abs has a higher impact (tensile) strength, which means it's less likely to break in a crash or any kind of short impact.
what printer are you using?
Tanks. Very helpful!
Крутобл!!! Thanks
Print it out of Nylon, 100% infill or carbon infused PLA.
+Shadow Black
That'll do it too...
Nylon I think is too flexible for long prints but perfect for clamps, mounts, accessories, etc.
good test but wear gloves
WOULD U RECOMEND ME BUYING A WANOH DUPLICATOR I3?
In my opinion yes
TNX
+Pawan Kumar yes, for that money you could build yourself a nice core-xy printer, but the i3 is fine for its money i think
Nice australian accent!
How do you get the ABS sticking so well on just tape?
For me as long as the bed is level and you have blue painters tape it sticks very well.
+radry100
As Panoreth said the painters tape works great. I use 3M branded tape. Smoosh the first layer down and use a very hot heatbed.
Love the strayan accent
what nozzle size did you use? for the arms?
I have a 0.4mm nozzle for all of my prints. If you were looking at printing arms or quad frames only, you could use a larger nozzle, like 1.0mm.
constipated mate?
hey ! Great video, but can you please tell me what is the material on your bed to improve adhesion ? thanks !
Painters tape. I use brand 3M #2090.
ok ! I have painters tape (3M blue) but I can't find the good Z0 to have good adhesion ...
May i ask as a conclusion, what would be your Filament of choice to print a Peon Frame with ?
+Grearson .x
I'd choose PETG because it has great strength and rigidity. Nylon is unbreakable but a little too flexible for long pieces.
Thx a lot my friend =)
Thanks for doing this!
Love your Quads! Nice Project as allways ;D
+Play Like Clyp3um
Thanks!
LMAO
You print on Cardboard?
+Dark Alchemist
I've been testing new tapes to print on. This one is 3M 501+ high temperature tape. It works fine but I think I'll go back to the good old Blue stuff.
Tech2C
Ahhh, from the bend marks it looked like cardboard, hehehe.
Great video. Where do you source your filament from?
+wattsyfpv
I use Polymaker, Taulman, and purchase the PLA/ABS from 3dprintergear.com.au
Tech2C Cheers!
You guy sound like Dave Jone lol
das racist!
pla > abs
I really disappointed to know that a chocolate bar can't be use as a quadcopter's arm :(
You should try breaking a PLA print under (after) a temperature stress test. I heard temperature swings weakens PLA, warm temp makes it soft/malleable and cold temp makes it brittle. Maybe you should blow dry with a hair dryer or heat gun or submerge a piece in boiling water for like 5 minutes, and putting another piece in a freezer for 8-10mins.
PLA chemical composition under annealing treatment seems to enahnce some mechanical properties. Actually some injected moulded parts have this kind of annealing process. And about "freezing" the material, it is likely to make it more brittle since it lets say lowers the Tg (glass transition temperature).
Do you ever get your heart rate up? Your capillaries are interesting. I mean no offense by this. It's not like I exercise either.
