Hooked on 3D Printing: What is the Strongest 3D Printer Filament?

This video discusses strength PLA, Nylon 910, ABS and Polycarbonate. Each material is tested by 3d printing a common hook and then loading the hook until it fractures. The following materials are used:

I feel like this is just an 11 minute commercial for WolfBite

The "inching" movement that they did while lifting makes the hooks easier to break

[PeterC]

I gave up because of the damn annoying background muzak...

[Maynard]

The PLA actually snapped under probably a couple tons of FORCE. The jerk caused way more force than the weight of the tire. Your method doesn't work, it causes too much jerk. Nice try though. Seems like you want us to buy your nylon/polycarbonate print-bed glue and filament.

sorry but this test is flawed when testing the pla the load you put on it was bouncing witch would make the load up to 2 times more and the rest of the test didnt bounce as bad.

that 3 or 4 second sound loop or however long it is - is excruciating!

I want to print 1ton durablity part for brick lifting, , , help me plz!!!

[erickarmenta]

What about PETG? how does it compares?

[whitefalcon]

would like some help here i need to reproduce a intermittent sprocket for a 35mm/70mm projector .the sprockets aren't available anymore any suggestions?from what i can see they were made from a titanium metal but are very light.

I'm very into what you've done for us by testing these! As a few people stated before, the jerk on the hooks cause a huge range of error in the tests. a better way would be to create a sled, lift it, and then load it consistently.
Then- to reliably test tensile, you should make a hook that is super beefy on both ends, with a consistent diameter cylinder in the middle- that will give you a predictable break zone in every hook, and will be pure tension. In the examples you printed, the failure was part bending, part tension, and probably part shear.
I'd also love to see pure shear tests, since I get a lot of small gears on my printer failing along layer boundaries. Although that would be a much more detailed video, since layer temperature and bonding time can have drastic effects on shear.

Still, these kinds of demonstration videos with consistent tests are hard to find. I was surprised that PLA outperformed ABS, and was impressed by the PC. Any change you'd try something with carbon fiber in it to see if it actually makes a difference? Thanks!!

Stopped the video at 5:34

Dollar store glue sticks work great on print beds.

Also, regarding your printer in the background, what kind of print project requires a 300 km/h travel speed?

[genecoppedge]

Yup the stress was increased by erratic operation of the forklift. You didn’t feather the lever but jerked the lever which caused the force to spike up sharply breaking the hook prematurely.

what filament is best for making car parts for customizing

[firedawg]

Watching the video it shows that the pla got shock loaded and when you shock load something you cannot get an accurate measurement of its strength. I would recommend you do a revisit on this video and not use a forklift but more of a winch or a come along to achieve a more stable way of pulling it up

[sparkeyjames]

I'm calling BS on the hook test. What you saw was more a test of shear strength than it was lifting strength. If they had wanted to show how much weight it could lift before failure they would have made a figure 8 type with the center at the same cross section as the outside cross section of the wall of one of the loops, somewhat like this 0-0, then lifted weight until the center lug or one of the loop walls failed. A test best performed in an enclose safety booth with a hydraulic expanding ram and short attachments to limit flailing at failure.

there is a difference between degrading a material and temperature resistance, pla wont degrade for decades if left outdoors in non extreme sunlight. This is not an issue with the materials biodegradability like suggested instead its to do with its temp resistance. the other thing is that stress test was bouncing really bad, you could be having 2 or 3 times the quoted force due to the bouncing.

[aprilk]

A bouncing forklift is not a good test.

[calendil]

Engineering design point of view: Wear resistance is much more important on gear designs (I am only mentioning about it because you showed examples) Tensile strength comparison under static load (or may be dynamic? We couldn't see how did you load it and I think that forklift was a bit too fast on lifting) comparison was great and I will certainly keep this in mind while considering. Thank you for the video

i wanna find that strogest filament that can feed 3d pen . do bodywork purpose like laptop, pc .. so i need strogest and heat proff filament .. any suggestion ?

[zoomtruth]

Why did you make a hook when you could make a circle, or other pattern which would probably hold twice as much weight as you showed on each filament???? Just wondering?
