- Which is the strongest 3D printed Model? We had design competition where our viewers designed their own 3d-parts that we printed out and tested with the 40 ton press and 150 ton force sensor. All test items are printed using PLA plastic with 0.15mm layer height

Rules for bridge design competition:
-Bridge is going to be placed between two steel parts that are 100mm apart of each other. So the gap is 100mm and then you probably should have something on top of the parts also :D
-Bridge is allowed to go 30mm under the plane of steel parts that are going to support it
-minimum width for the bridge is 30mm
-No maximum height
-Bridge has to have at least 15 mm wide clear bath on middle
-If you want to use other infill % than 100 please mention it on email
-If you want to your name/user name showed on the video please mention that on email. (I was too busy to go through all emails with this video afterwards to check do people want something on the screen)
-No roofs on the bridges. We have to be able to push down on the road at roughly on middle of the bridge
-Send your designs to hpcsuomi@gmail.com
-Maximum weight for all designs is 150 grams

Congratulations to winners! I will send email to you shortly to ask what stuff do you want etc. I had great plan to contact everyone who's models I printed to add names/user names on the video but I was way too busy for that :D But thanks for everyone taking part on this and good luck with bridge designing!
Awesome, I've always wanted to test what shapes are for building purposes. Example what shape building would be strongest against forces from the sides or above. 👏👌👏👌👏👌👏👌
@@ChiefKapui If these get popular I could do some other competitions also on our second channel. Like best 3d printed air cannon projectile etc :D
The first 1 didnt break it was maybe designed that way.

Am I the only one who thinks that the words are suitable for heartbroken people?
The first one was literally an accordion. It was ribbed horizontally, and had air gaps positioned throughout the part that would allow horizontal expansion of the material. It's like they were trying to make it compress easily.
That’s exactly what they were trying to do
I think they were trying to make it able to compress without breaking
Ribbed, for her pleasure.
@@BobMonkeypimp internet historian?
I think what they were aiming for is that it would quickly collapse but he would only call it broken after it breaks apart from the compressed shape (basically trying to enter with a shape that's half as tall)
2:22 “ it was really complicated but not that strong”
Just like my life
😂, like everyone else.
Change just like my life to end war German tanks and you got a history joke
The first design would make for a decent one-time shock absorber.
The designer is in the comments and said that is what it was designed for.
In terms of energy absorbed, it would be the best
Alek Yoder so u invented that?
Alek Yoder if you could, try a mix of pla, and flexible filament. This will give it some flexibility so that it does not crack as easily, and if you put the ridged pla where the load will compress the flexible mix making the solid cylinder you want in the end, and have the flexible filament weaved with the ridged pla filament for the compression ridges to allow for more bend, it will give a little less resistance in the beginning stages, but won’t break in the early stages like now. The last stage though should keep the strength because it would be the same solid rigid cylinder you wanted.
Until you realize it’s made of plastic and will probably break easily

Yeah this was a great idea to interact with the viewers instead of a random draw of the box giveaway. Definitely should have more of these competitions!
Design tips for anyone wondering: an intricate cross section does not necessarily make for a strong design. Sharp corners introduce stress concentrations. That's why the first one broke so easily.
That first design is actually great because even when failing it does so gradually and consistently at 180 kg. No catastrophic fqilure
It was designed to become shorter and stronger under pressure, didn't you see all the notches on the sides?
It works as a spring
great?
If i have the choice between 2 designs, one failing catastrophically, the other failing at less than 10% of the firsts load..... i'ma take the first design every single time. You can just specify as 200 kg max force allowed and not only would that still be higher than the second design, you'd not operate close to failure but with a safetymargin of 10.
The design was utter crap for the given task from every conceivable point.
That's not even a silver lining. "It sucked 10 times faster, but it sucked with more predictability"? Nice thought but theres really no redeeming qualities to that design.
You made a typo
I find it's interesting how the swirly shape in the no rules competition didn't break as much as it got squished despite being made of hard plastic.
Yes I think it may have been because the cross-section of the swirly thing is a hexagon. The ratio perimeter/area of the hexagon is larger compared to a circle (where that ratio is the absolute minimum), which means the external perimeters can stretch more because there's more length compared to the internal material being squashed outwards.
The swirly one was also the shortest one, therefore it had less places to break. I liked that one because it had some logic behind it
In all reality it's just ABS plastic which is kinda soft
EDIT: I used to run a 3D printer at my school....stuff squishes unless you actually make a strong support/use the right support pattern inbetween the layers
i think they get hot
I just love the description "swirly shape". It's funny but apt.

Hi, next time. Put in a dial zeroed to the hight of the part being crushed. When crushed to less than 90% height the highest force is recorded. Then you have an objective measurement.
He looks at the maximum force to crush and records that value. Pretty fair for ultimate load testing
Its not fair, its not scientific, its just destruction for fun.😁
it's not a precise test setup, if you notice there is horizontal deflection, which will through off the results on some of the prints, since it's not purely compression, it's also shearing forces. which is less consistent. also only testing single models in a single material doesn't offer a huge insight in 3d printed object strength. the most objective measure is which one failed in the coolest way.
Maybe a steel circle too, to hold it in place and have that diameter as a width parameter for the competition.
Not really. For example the first one have a crack in a very start

Problem with 3d printed crap it's structure is nothing like that of an egg shell timber or iron.
@@girlsdrinkfeck no shit, that's cause it's made of plastic and not eggshell, wood, or metal.

The bone structure one is a really good way of showing why our bones are shaped the way they are. The bones in your appendages are actually designed to break in the middle so they don't shatter and are more likely to heal.

Would you like a side of green eggs and ham with that?
Idk why I read that with 007 style
@@TurnipCart yes. Please make the eggs abnormally big, and completely hollow.
Oh wow, I never imagined my tube could actually do that well.
Some people already mentioned that triangles for the hollow parts could have been better and I do agree. I just chose the rectangle shape as it was easy to replicate around the tube while keeping the structure thin so to concentrate the mass on the outer shell (if it even matters :P). But I guess more accurately, the hollow shape is a rounded corner trapezoid with slight curve to it so that it follows the bigger circle.
I also wonder if a plain tube could have given the same result. Or maybe the shell structure helps with the failure mode?
Which time was yours on?
@@korjaa I think it's simply the fact that tubes are incredibly difficult to compress, which is why you see automotive jack extensions or hydraulic press extensions made tubular.
I think having many doubled walled vertical infill lines forming a bunch of "I" would be best because they help the tube walls distribute load across the medium without causing a failure mode that would cause tube wall to blow out.
Pretty much what was designed.
Also triangles can be weak on 3d prints as only the tips adhere to walls, (or at least one tip) whereas squares/rectangles/trapezoids can adhere complete sides to walls.
In short, simple wins again.
@@korjaa I'm afraid the laws of physical structure patterns we use in construction cannot represent that of 3d printed polymer layers
Thank you for closed captions. I am hard of hearing and even a slightly garbled text version does help me follow the details as well as context.

8:32 Here you are crossing the structural strength vs. material strength barrier...
Here VEE goo!
Nothing better than seeing things get crushed by a hydraulic press
Crushing them is even better than just watching :D But you don't have to clean so it evens things out :D
This is also a great showing of how 3D prints can be rather strong :)
3D prints are strong if the force acts in a direction where the printing layers are compressed.
However if you rotate it 90° and have the force act perpendicular to the layer direction they become extremely brittle and weak
@@Naveication I know, I own a 3d printer.
Surprised no one did a vertical honeycomb design
That's basically what the large cylinder is. Honeycomb is not inherently more stable; it's just a shape that lends itself well to being made of layers of resin reinforced paper.
Also it told better than spheres
mike greene yea most of IKEAs tables are filed with a cardboard honeycombs but they are still ridiculously strong
You should have specified a weight or something. I think in a competiton like this, you'd just win when you make it a solid block within the size limits.
150g max
He did.
@@castor2000 Oh ok. Fair enough, then it is a good competition.
@ true.
Still it would have been interesting to see just a solid cylinder within the specified height and weight as control
Eggs are strong when the pressure is applied equally across the whole surface...
Send it to the Mariana trench and it will survive better than any other form.
I have tested that one :D Just 2 miles of water and they will pop czcams.com/video/z789cHXHUng/video.html
Not stronger than a sphere, but eggs don't roll far when they fall out of the nest.
@@HydraulicPressChannel two miles of water is a heck of a lot of water, and far more than what the human body could ever handle.
Probably not because they are still hollow.
Juicy eggs are not hollow have you heard of the food eggs or how chickens are made? They have a small amount of air but that does not make it hollow
I like how you explain things in a way that shows you understand what is going on but you don't get too detailed and distract from the crushing action
This is a really cool video to watch coming off of my strength/mechanics of materials class I did last semester
The "Bone" 3d print hurt me when it broke.

it's nice .
I'm actually imagining what is happening when your bones are broken.
I would love to see these tests done again with static instead of dynamic loading (e.g. stacking steel plates on top). I wonder how the results would differ!
This channel is still getting better and better. Keep it up.
The point of the first one was to crumple at first but be stronger later. It would be nice to see how much pressure it took over time with a graph chart compared to the others.

3:02 “I think it looks kind of bone”
My favorite part of video lol
This video looks very fun!! If you do make a bridge competition video I'll submit the bridge design I made in my highschool many years ago, and won. I made it out of toothpicks though. I'll have to learn how to use design software before I submit it.
There's one major flaw regarding this that you'll have to consider, that almost everyone is not realizing. Like with toothpicks, they have an innate strength built in due to the wood fibres. 3d printed materials are made purely from horizontal strands of plastic, the physics of compression, shear, and flexion are not the same as if connecting solid members. As such, the strength of a "toothpick" printed by a 3dprinter would be entirely dependent on what angle it is printed at.
Additionally, the rate at which a layer is printed upon matters, as the sooner it happens, the less time the plastic has to harden. If it doesn't have time to cool, the layers could settle lower on their own, leading to gaps and weakness in the subsequent layers.
So it's less of a contest of engineering design, and more of a manipulation of the 3d printing process that would lead to victory.
Very fun idea!
3:23 felt like my bones were breaking just hearing that sound!
I was just thinking about bridge design when you said it.
Guys: buy a hydraulic press
Also guys: we could make a religion out of this!
When you can 3D print a lump of plastic small enough to put in your hand, yet strong enough that a Groudon could stand on it without it breaking
I really liked this. I am looking forward to seeing the bridge one. I might even consider submitting one, if I have time.
