Polymaker Hook Tournament: Round 5 and Quarter Final

- Опубликовано: 6 июл 2024
- Polymaker is hosting a 3D Printed Hook Tournament.
We invited the 3D printing community to show off their engineering skills and design the strongest hook!
During this single-elimination tournament, hooks are facing each other in a tensile strength contest until one of them breaks or let go. From the qualifiers to the final, only one will survive! However, the top 3 hooks will be rewarded with prizes.

CNC Kitchen holding on!
Yes! I honestly didn't think that design would go that far, I was wrong in doubting german engineering hehe, but I think it is close to the limit, the jaws were opening and crazing started to appear
Looking at the failure modes for these I wonder if non-planar printing would have made some of the designs more competitive.
I really thought #Sendit hook failed, I was like "No way!"
Btw thx for the teaser at the end of the video, its just perfect! you guys have destroyed some stuff im sure!
Whew! Close one!! :-)
This was a good format
lets go CNC KITCHEN!!!!!!!!!!
This is getting really interesting!!!
Thats just insane how they are getting stronger than the steel hook
Logical, they aren't even classified as hooks ! just unfair rules, and ohhh what a surprise CNC kitchen is gonna win his 30th 3D printer ... The only hook this far of the tournament I do have respect is CCC which is simple and so strong but failed because they've tested it ... twice !
@@skyhacker6 i don't think it was his design, I thought he was going to print and send in one from his viewers design wasn't able to print it on there own
@@samhagen5607 Yeah I know, but don't you think it's a little bit strange that obviously this design signed "CNC kitchen" went this far away in the tournament ? Anyway, those hooks are closed even if they said there is a small gap in between and quite strangly, 80% of the hooks are designed the same way (leaving to the side the spiral one which are for me pure cheat !). For the next time, they should more carefuly think about the rules to prevent people getting smarter and playing with them (the rules).
@@skyhacker6 rules are rules and these hooks followed all of them. Also cnc kitchens hook got this far because it good not because he is a popular youtuber.
next year is going to be crazy with people learning from this one
A simple "will be attached to a Ring of Size y/x" would have prevented these closed loops. at this point, you´re more testing material strength and not design strength.
Nevertheless, no participant to blame and still kinda interesting.
Mine was spiral (SBG) and you can hook it to a ring... it just takes a little time to pass all the loops through. I wanted to make sure there wasn't a single reason to be disqualified, nobody knew how strict Polymaker was gonna be.
My hook held over a ton (2,000 lbs), so I'm happy.
The way the loops slided and re-accommodated was impressive! Great design!
Noooo, you were my favourite to beat Armour Aus. That one is still a dark horse as to how much load that type of design can hold, as is Sendit. And I still dispute the Aus design for post processing even though it's done while pulling it off the build plate but ah well, polymaker evidently allowed it.
It will be interesting to see the absolute loads carried by the finalists. We could have a situation where the second place hook is actually weaker than third.
@@Bordpie I wonder if Polymaker will factor in the breaking force of each hook to determine 2nd and 3rd place. Obviously the hook that never breaks is 1st place, but using the breaking strength of the hooks would give more accurate standings than just using the bracket results. It would take the randomness of the initial seeding out of the equation. (Of course, I MIGHT just be lobbying for my hook. Maybe.) :)
If they do this again and don't want 90% clones of the winning designs from this round, I think they ought to use a class system such that people are still encouraged to try optimizing interesting but inherently weaker designs like S hooks and open C hooks. There could be modest but still valuable prizes (like spools of filament) for the winners in each category. A separate "unlimited" open category would be where a grand prize like a printer would be found, but you'd only be allowed to enter in one category, so if you go for the grand prize, you're not going to be competing in a specific limited class. Alternatively, a grand prize could be awarded after a final run-off of all category winners.
To alleviate some of the issues with this contest, they should reduce the max weight (so test machines can handle it) and specify that submitted hooks have to accommodate both the metal S hooks specified this time AND U hooks. That should avoid designs that ONLY work with one specific attachment. I also think allowing standard (not dissolvable) support material removal as the only legal post-processing activity would allow considerably more creativity in designs.
Potential classes:
* S hooks
* open C hooks
* latched C / carabiner
* spiral (including vertical spirals?)
* unlimited
It would also be cool to have a consolation prize for the strongest hook that did not make it to the finals, since seeding can be cruel to some and ridiculously gracious to others.

PLA - 1, PA6-CF - 0 :-)
GG Armour Australia.
I've been HOOKINATED!!!
Captain hook started to loose loops! D=
Captain Hook loosing loops. But they switched to new hooks. I thought they weren't doing that until the Semi-final round.
@@twinturbostang Me too!
btw... I'm starting to think they'll use a forklift to break the last hooks ahahah what do you think?
@@santiagoblandon3022 I mean... that's one way to do it! lol
According to the Challonge live tournament, Sendit has beaten Marc Kalweit.
Interesting!!! :-)
@@twinturbostang All the entries to the hook guessing competition are in as well. I believe it closed just before this video came out and there are 780 entries so probably 150 guesses across 16 finalists (although probably more since some guesses will have been hooks which have already failed). The popular designs like CNC kitchen probably have a large chunk of those votes as well.
@@Bordpie More suspense for me though, since I don't know the "official" outcome against Marc Kalweit and Captain Hooook. At this point, most of the hooks are literally ripping through the material. I hope that's good for me since my hook has the largest cross sectional area possible. But we'll see. The other hooks look so strong!
@@twinturbostang I also know now that my hook reached over 10kN of force which is nice, along with all the other semi-finalists, like you mentioned. I find it amazing that this piece of plastic in my hand can hold over 1 metric ton!
@@Bordpie Did you test it this high? Or was that from one of the matches?
No one has broken the 1 metric tonne, yet....
Won't be long. :-)
Well shit
