Fun and interesting experiment but I could not help but be concerned that one of the cubes would crack and the pointed up shards would pierce your foot like a nail. I was much more comfortable when you switched to using the vise.
It makes me laugh to see some comments complaining about the quality of the test thinking that Joel wanted to make a scientific video lol. I mean Joel's channel is such a fun one, he can smartly mix useful technical output while being a fun video. So many people like Joel's videos just because of this specific fact, everybody enjoy at least a side of the video whether it is the fun part, the technical, .. Anyway just fun to read the comments :D Thx for the content Joel :)
I have been quite "offline" as of lately. But I noticed that is the mic is pretty cracly all the time, try tuning it down 3Db on the Inpurt gain of the recording device.
something to consider as well is with the blue/large one, the "bottom" had no room to flex when it finally started breaking. The bar from the vice prevented movement.
Seems to me that the polymax had a little more elastic and plastic modulus than the PLA. I.e. the PLA was more brittle. The polymax seemed to bend a bit more even when failing, where the PLA just seemed to shatter. Interesting results.
I'm reminded of testing Thom Sanladerer did with proto pasta's HTPLA, which is annealable (able to be heated to increase strength). I'd be interested to see how the annealed HTPLA stacks up against the Polymax.
The Sony RX100 has a really good super slomo setting (or high frame rate capture) which would have been great for filming the step on test. FYI for next time.
Not an ideal geometry if you wanted a structure to be strong enough to resist compression forces. However, what would be more interesting to makers and prototypers is comparing PolyMax against ABS, Polycarbonate, PC Max & PC Plus. With various infills to full solid models. To me 3D printing is far more valuable to engineering workable and pre-production parts, rather than figurines and desk widgets.
That was not a little bounce. Might feel a litte but probably more than a g. I see you are sporting those 3D printed shoes. There are theoreticians, experimentalists, and Joel, the qualitativist!
Nice! Could the vice be a new benchmark of sorts for filaments? Perhaps print the torture cube or something similar and then have different areas marked on the side of the vice to give it a rating to see when it cracked and then when it completely crumbles?
I was half paying attention to this video as some early morning 'podcasting' at work. Then you said you were going to step on things. That got my full attention. Nice.
Impressive material. I imagine it'd be even stronger with a tighter infill (and maybe a honeycomb pattern, though I don't know if that makes any difference.) I may have to get some of this stuff.
I had a similar comment so at the risk of being repetitive, perhaps you could do some actual stress tests that would be more standardized such as how they measure material properties for engineering. Still looked like fun. Will check out the polymaker product.
Okay, so what about it's hardness? Judging by the failures, It seems a bit softer of a blend than regular PLA giving it more flex. I think it's has a good hardness for a PLA blend - where standard PLA is almost too hard.
Fun video Joel! Josh was like a ref keeping you in check. Try the weight atacking like Daniel Norée did with his skateboard truck test and nearly died when the weights fell on him.
Hmmmm....... I think I'll stick with the standard PLA for now, in the UK the Polymaker Polymax is around £50 for a 750g spool and the Colorfabb PLA is about £10 cheaper for the same amount, still way outside my budget for filament unless I'm pushing for Nylon or something exotic. Might keep it in mind for when I print my kayak though :D
It's such moments that make you cherish Thomas Sanladerer's more rigorous tests with measures of forces (newton etc...) but not restricting opinions to some "feelings". By the way Thomas is a German... If BMW's engineers were testing your way Joel, we'd not enjoy their wonderful cars...
I have an idea, build an antweight or beetleweight combat robot (a spinner and or a hammer, your choice, preferrably both but spinner over hammer) and test how impact and or cut resistant this stuff is
I think it was unsafe to begin with. I have had wonderful Adidas trailshoes that held up for more than a decade, and when they failed, they revealed a flexible fine steel mesh hidden within the sole - so now i know why always felt so safe stepping on any kind of stone with them. They were actually so well engineered that they failed in multiple spots at once: both the upper and the sole failed simultaneously, but unfortunately quality hasn't been like this for a really, really long time. Wouldn't want to step on a hard plastic piece that might shatter in anything but those or something similarly reinforced. So yeah if anyone has awesome shoe shopping tips (girls' trail shoes, average arch and width), give them to me.
@3D Printing Nerd, your videos are awesome. One comment on this one though, regarding the mechanics of how it failed, you got quite wrong. By standing (or bouncing) on it you provide constant force (weight) and hence stress, regardless of deflection. Hence, as it breaks, the breakage becomes more violent (as seen with the white and green models). In a vice the stress comes from the displacement, hence as soon as the plastic yields slightly, the stress is entirely removed. I would love to see an actual test of these PLA's (print a dog-bone type thing and load with weights for constant force applied) because I think your conclusion was correct (blue was strongest) but I like my scientific method a little bit... Please keep up the great vids.
Hmmm. May have to try the Polymax PLA. I printed the Origami Carabiner by ddf3d.com from Thingiverse yesterday using the Prusa silver PLA that came with my i3 MK2S printer. A very cool print that came out great and appears to be quite strong. But, based on this video, the Polymax would make it considerably more so. Not that I'd use it for climbing mountains in either case but I bet it would definitely make a difference. Thanks for another interesting video, Joel. High five.
How's that Flexplate working for you? I'm guessing the XYZ/skew auto-calibration's totally out to lunch with the big magnet on the bed, and would be interested in how you handled that (or in hearing that I'm just totally wrong).
+William Shreckengost working very well! Calibration won't work with it on, so as long as you add it after calibration it works great! I filmed a short video on this and my editor currently has the footage.
This is a pretty uninteresting test: the real issue with 3d prints is layer delamination which is shear, not compression, as you tested (the flex seemed to turn the compression into some shear force). Tom is doing shear tests by dropping a hammer from a known height and hitting parallel to the layers. Next time try some oven annealed PLA.
It's not - it's the standard wipe, however, I've installed a BuildTak flexplate system. It makes the bed height a little taller, so the wipe doesn't exactly wipe like before.
Romaji Was going to say, it's almost unbearable to listen to on my S8. I think he needs a new microphone with a dead cat to cover the mic for wind noise
That would change where the stress is being transferred through the model. Most of the stress would go through the "tubes" of the model instead of the bends. The Bends here are a lot weaker.
Now that the Full Joel is a unit of weight measurement, do you have a conversion or reference to either imperial or metric measurements? (i.e one Full Joel equals 195 imperial pounds). Please update google for future calculations! High Five!
They are called "Feetz", they are custom 3D printed shoes made for him from 3D scan of the feet. They're very expensive and they flex in weird and potentially uncomfortable ways, but he says they feel great otherwise. Also they failed on him numerous times after just a little walking, the sole easily developed a tear right through it, but they changed it to try and remedy the issue. If i were a wee bit more cynical than i am, i'd say they were perfect shoes for an American.

Send one of these to the Hydraulic Press Channel!
The sound is so crackley
mjl7332 sounds like the audio was peaking and was being clipped by the audio recorder. Doubt someone checked levels :( [happens to the best of us!]
Fun and interesting experiment but I could not help but be concerned that one of the cubes would crack and the pointed up shards would pierce your foot like a nail. I was much more comfortable when you switched to using the vise.
Also as the piece of plastic breaks a piece could fly up and hkt someone in the eye
What SMASHING results. You could say this BROKE my mind. Ok, I'm done CRACKING these jokes.
Stop before you BREAK something.
Oh wow, these puns are CRACKING me up
OH GOD THESE TEARABLE PUNS
This cracked me up
It makes me laugh to see some comments complaining about the quality of the test thinking that Joel wanted to make a scientific video lol.

Music was a bit loud on this one Joel, made it a bit hard to hear you at times. Thanks for sharing mate.
BREAK THOSE CUBES! #fulljoel
👌🏼😂 LOL that’s so much fun to watch!! I’m testing their PolyLite filament at the moment. You want me to step on that one too.
Hmm interesting results.. The Polymax just flexed and bent rather than give at the layers.
Thanks for sharing this!
Welcome! That's what got me, it flexed before delam'ing. Crazy.
something to consider as well is with the blue/large one, the "bottom" had no room to flex when it finally started breaking. The bar from the vice prevented movement.

Oh that's right! forgot about that awesome mode while filming. Will remember for next time.
Great, another unit of measurement for the already complicated imperial system, #FullJoel. ;-)
that "I cannot remember PLA" looks like Polyalchemy Elixir
If you are going to stand on it make a larger base i.e. thicker.
Then use the same model . This will allow the model to stay up right
An interesting test. I wonder if the prints would hold up better if you had thicker walls, and denser infill?
What a unique way to break your ankle! ☺.
Entertainment at all costs.
Dude, the shoes were kinda funky.
S. Hurtt he 3D printed them.
They were actually 3d printed by a company called Feetz
Perhaps hanging the cube and attaching weights would have been more consistent. I'm impressed by the strength of all the models.
I love how scientific and objective your test methods are.
Not an ideal geometry if you wanted a structure to be strong enough to resist compression forces. However, what would be more interesting to makers and prototypers is comparing PolyMax against ABS, Polycarbonate, PC Max & PC Plus. With various infills to full solid models. To me 3D printing is far more valuable to engineering workable and pre-production parts, rather than figurines and desk widgets.
You should have added support to the bottom so the cubes could fully experience the #FullJoel without the stand breaking
FULL JOEL!
That was not a little bounce. Might feel a litte but probably more than a g. I see you are sporting those 3D printed shoes. There are theoreticians, experimentalists, and Joel, the qualitativist!
Surprised they didn't break the shoes lol
Nice video. Joel, do us all a favor: come new years, or whenever, explode some prints. Ok? seems like a great idea that has no downsides :3
Nice! Could the vice be a new benchmark of sorts for filaments? Perhaps print the torture cube or something similar and then have different areas marked on the side of the vice to give it a rating to see when it cracked and then when it completely crumbles?

3D Printing Nerd
The only person who can make a video about stepping on a cube 12 minutes long.
Only thing that I could think of the whole time is what you have on your mk2 print bed.
I had a similar comment so at the risk of being repetitive, perhaps you could do some actual stress tests that would be more standardized such as how they measure material properties for engineering. Still looked like fun. Will check out the polymaker product.
The way you torture those 3D printer torturers shows your love for 3D printers. 😁
If you ever do this again (which I hope you do) stand on the model closer to your heel, you'll be able to balance far better...
Angus did say PolyMax was his "go to" structural filament.
Okay, so what about it's hardness? Judging by the failures, It seems a bit softer of a blend than regular PLA giving it more flex. I think it's has a good hardness for a PLA blend - where standard PLA is almost too hard.
Nice work Joel. But honestly, next time if want to stress test something send it my way and the big fella will stand on it lmao ;-). Cheers Aaron.
Fun video Joel! Josh was like a ref keeping you in check. Try the weight atacking like Daniel Norée did with his skateboard truck test and nearly died when the weights fell on him.
Now that's some useful and practical information! Great idea /video :)
So this ploy max seems as strong as nylon but you don’t need a enclosed 3D printer to use it correct!
Hmmmm....... I think I'll stick with the standard PLA for now, in the UK the Polymaker Polymax is around £50 for a 750g spool and the Colorfabb PLA is about £10 cheaper for the same amount, still way outside my budget for filament unless I'm pushing for Nylon or something exotic. Might keep it in mind for when I print my kayak though :D
You went #FullJoel , never go #FullJoel .
I didn't get that memo. Maybe that's what I've been doing wrong all my life, ...going #FullJoel
What are THOSE?!? Seriously what are they. They seem comfortable.
It's such moments that make you cherish Thomas Sanladerer's more rigorous tests with measures of forces (newton etc...) but not restricting opinions to some "feelings". By the way Thomas is a German... If BMW's engineers were testing your way Joel, we'd not enjoy their wonderful cars...
Tom is good people!
Forget torture tests, the stepping test is next big thing.
I can build a frame to build my own car, the possibilities are endless mind boggling.
I have an idea, build an antweight or beetleweight combat robot (a spinner and or a hammer, your choice, preferrably both but spinner over hammer) and test how impact and or cut resistant this stuff is
You need a thicker base. That's why it keeps snapping and rolling over
You're going to put an eye out with that thing
Well, not mine - I used protection!
New official unit of filament strength. Full Joels
The full Joel is now my fav thing!!
You need to modify the model so it has a thicker and wider base. Maybe print the base with a higher infill.
That's very true. Round two!
New standard for filament strength testing in the 3D printing industry: Standing a #FullJoel 😄
But isn't a Joel an inherently variable unit ? :D
Ok Joel, time to send some to Finland to the hydraulic press channel.
You know you have made it big when you lose something in the shop and the camera guy has to get it for you.
Really impressive torture testing of a torture test! Also extremely unsafe at 7:25! What if it failed?
Lucas Hartmann Face dive into the floor?
And cracked hands haha
Kik Stark I was more worried about sharp edges and deep cuts. Thankfully the material does not fail in such a threatening way, it just deforms.
I think it was unsafe to begin with. I have had wonderful Adidas trailshoes that held up for more than a decade, and when they failed, they revealed a flexible fine steel mesh hidden within the sole - so now i know why always felt so safe stepping on any kind of stone with them. They were actually so well engineered that they failed in multiple spots at once: both the upper and the sole failed simultaneously, but unfortunately quality hasn't been like this for a really, really long time. Wouldn't want to step on a hard plastic piece that might shatter in anything but those or something similarly reinforced. So yeah if anyone has awesome shoe shopping tips (girls' trail shoes, average arch and width), give them to me.
I entered the Polymaker hook contest with this material. The hook withstood over 1000lbs.
That’s awesome!

Will you be putting up a review of the Buildtak for the Prusa?

Time to switch from Joules of force to Joels! Awesome as usual.
Audio sounds distorted, is that just me?
mic was too hot. music is too loud. we've made adjustments!
I am puzzled why the initial test was to step on it in that orientation
Joel, looks like you're doing a special wipe on the Prusa. Can you share that gcode?
It's not - it's the standard wipe, however, I've installed a BuildTak flexplate system. It makes the bed height a little taller, so the wipe doesn't exactly wipe like before.
Wow, thats funny. Totally thought you had implemented a nice zigzag wipe which I always felt would be neat.
Let's start using FullJoel as a unit of measurement
I feel like Joel is just a puppet for the cameraman, it's as if the cameraman is telling Joel what to do.
#freejoel
Lot more crackling than usual
Romaji Was going to say, it's almost unbearable to listen to on my S8. I think he needs a new microphone with a dead cat to cover the mic for wind noise
Unscientific but rather practical. Thank you.
+Robert Palmore hopefully entertaining as well?
definitely makes me want to buy some Polymax!
getOrvillized thats the point of this video
Angus gave you a shoutout! #FullJoel
I want to know the effects of the Sun on this for outdoor use. UV and TEMP effects on the Polymax?
Love the 80's music playing.
You're videos are so good. im gonna buy a 3d printer soon!!!
Joel, what shoes are you wearing in this video? They look AWESOME! 👍🏼
+Josh Hibbs Feetz! They are 3d printed shoes. I did a few videos on them - have a look!
How is the polymaker polymax filament stand up to uv light?
How does the polymaker polymax filament handle being in a very hot car?
should have put scales underneath the print to see what weight the model broke at.
SENSIE = MARTIAL ARTS
3D PRINTING SENSIE = #FULLJOEL
This video should be called torturing the torture cube
Dude with all that stuff in your shop it looks just.......like mine. :)
You were not centering your foot on the model from front to back
Model size versus strength should follow the inverse square rule
Lol, you should let me do this test... 102Kg of destructive weight.
Hahahahaha
Why not stand on the flat side of the cube?
That would change where the stress is being transferred through the model. Most of the stress would go through the "tubes" of the model instead of the bends. The Bends here are a lot weaker.
Perhaps you should have done it whilst balancing between two desks! :)
MOAR DESKS!
how will Polymax do in a hot place like a car? that's what would like to know.
PolyMax™ PLA is a PLA so same soften temp as PLA (~60˚C ) :)
Where did you get those shoes Joel?
3D printed?! 🖐️
JUST saw the "next" video pop up. 😄. Mission solved
Now that the Full Joel is a unit of weight measurement, do you have a conversion or reference to either imperial or metric measurements? (i.e one Full Joel equals 195 imperial pounds). Please update google for future calculations! High Five!
Got join the assassin brother hood to learn proper eagle posture
This needs to be the SOP when testing filament haha
Again a great Video, Joel! But why is the sound sometimes so ,,crunchy"?
+LBLJLALRLNLE LHLALNLSLELN new mic and I was overdriving it. Made adjustments after this video and it should be better going forward.
I think it would work better if you use your heel not the front or middle of your foot.so your weight is more in line with it.
what shoes are those they look mad comfortable
+VbaGGz2 very. Feetz 3d printed shoes. I did a few videos on them. This is my third pair and they are massively comfy.
Mr. Miyagi would say: "you must learn balance, Joel San!"
What difference does it make if it's on its side
This is such an awesome channel :D
+Code-Grammar THANK YOU!
Your shoes look incredibly comfortable. What are they?
They are called "Feetz", they are custom 3D printed shoes made for him from 3D scan of the feet. They're very expensive and they flex in weird and potentially uncomfortable ways, but he says they feel great otherwise. Also they failed on him numerous times after just a little walking, the sole easily developed a tear right through it, but they changed it to try and remedy the issue. If i were a wee bit more cynical than i am, i'd say they were perfect shoes for an American.
How on earth you didn't realized that you're too far from the table making you lean, hence the same roll to the same side.
dang he has the shoes we all drew as kids
