In vertical position all the three stresses accumulate in between the layers which are weak points. Meanwhile, in horizontal position stresses are applied to the layers all together. This video really helped to realize this. If you asked me before, I would definitely go with the vertical one.

I'm surprised at how strong even the vertical one was. FDM is amazing!

Thanks for this - the information is useful and timely for me. I'm working on a horizontal mount for a joystick that has both a screw thread and a nut. This confirms that the planned horizontal print should be stronger than my other options.

Brilliant video! So interesting for such theme. Keep making good content and your channel will raise. 100k I believe!

Great video. The first I’ve seen on how printing orientation effects and objects drinks. Very very interesting.

This was very helpful! Last night I experimented with some brackets printed on my CR-30. Definitely need to rotate parts by 45° since that’s the equivalent to printing horizontally on a normal printer. The ones printed right in the bed broke as I removed them from the bed. But the ones printed at 45° were really strong! Which for batch prints I closely stack them in Cura so that it uses the previous print as a support. This reduces waste with supports on multiple prints.

What a great, clear and methodical video you've published. Thank you.

I appreciate the thorough test, good job!

Really impressive! I never thaught they would hold this much. And fun way to test it :) Although (depending on how strong you are), you may get more force doing it the opposit way - attach the bolt to a barbell on the ground and lift it. And once the bolt gives out, you don't fall to the ground with a lot of weights on top, haha. This also really show the weakest point with 3D printing - layer adhesion.

This is the kind of stuff i want to see, exactly what i lay thinking about in bed.

Great Video, very clear illustration! Keep them coming!!

This presentation style, despite the accent, is keeping my focus much better than the channels that send mass produced content. A++, hoping to learn what I day-dreamt through several videos on the topic prior.

Luv the vid. it helped me learn that the heat of your nozzle helps a lot with layer adhesion. Also proving my theory that I had by myself. That printing The item oriented perpendicular of the force being applied helps as well.

A like for detailed and tough test 💪 using self.

Such an interesting experiment! Thank you for sharing it!

I watched the most useful video, one of the most successful tests in the field of 3D printing, thank you.

Thanks for the engineering approach, one thing your results may differ than the website data is because you did the experiment by printing bolts. The threads on the exterior surface are the stress risers so they reduced the max. stress. The correct method would be printing straight bars and testing it on a setup similar to extensometer. Very much thanks for the video by the way, it gives clear understanding of the effect of printing direction on the strength.

Another interesting test would be to print a solid, smooth bolt (no thread) and then use the die to add a thread. I think that might be stronger than printing the thread.

Muchas gracias por el video, sinceramente no había pensado en que, la posición de impresión podía afectar la resistencia de la pieza. Saludos de Bolivia.

This is very interesting stuff. I used to fly model airplanes, and for mounting the wings to the fuselage there are special nylon bolts in the market. The idea behind these is that in the event of a crash where the wing strikes an obstacle, the bolts would shear off and the wing would be undamaged. In practice however, the bolts would often prove to be too strong, and either the wing would be damaged anyway, or the mounts would tear out of the fuselage together with the bolts. It would be a fun challenge to produce my own bolts that are strong enough to survive any aerobatic maneuvers of the plane, but would be fragile enough to break in the case of a crash.

@johnsamu

2 жыл бұрын

Shouldn't be too difficult, just adapt the market available nylon bolts by making a radial groove in it. Best to do with a (mini)lathe if you have one. You can easily make a bolt that will break when you want to. It's somewhat like steel testsamples are being made when steel properties are being tested.

super idea, super done, very convincing! I once had the case that my printed screw broke and so I printed it horizontally - after this video I know that I was right :) And now I will always think of this video when I want to print a screw (and I will print them all horizontally)

Pretty cool experiment, thanks for sharing with us!

Awesome video! The results may vary if the bolt print orientations (vertical, horizontal, 45) are all printed separately. Printing all of these different orientations together will affect the infill/print path of the bolt. This would then effect the lattice/crystalline structure of the bolt. But you sir deserve a tensile test machine instead of risking your own weight for a plastic bolt haha. Thank you for the great content!

Thanks for this! This is an instance where I could see the value of using filament meant for printing support material, in addition to the filament that you are using for your bolt.

for the diagonal one, it might be that at a certain position, under shear stress, it acts like the horizontal one, as the fibres can be diagonal to the shear stress, similar to the bolt with the horizontal fibers.

Thanks. I printed a replacement bolt for my toilet seat. Those bolt need to be made of plastic because a metal bolt could break the ceramic bol. Obviously, I followed your advice and printed it horizontally with supports. It was not pretty on the underside, but it's surprisingly strong for PLA. Lets see how long it will last.

Boa tarde! Esses testes que você fez são muito interessantes, pelo menos para mim! Parabéns!

What if, you print the threads to nominal (or +0.1mm) size and then heat the threading die to 80C (into PLA glass transition). Will it smooth out the surface when "cleaning the threads" or is it possible that the heat will somewhat compress the threadform with the die into correct shape.

Wow... Thanks for your efforts demonstrating this. I have troubles printing vertical bolts but now I have a clear idea on what to do the next time. New subscriber here!

I have always wondered about this! Thank you for doing this.

The Russian saying translates to measure twice and cut once. But i like the way you used it in this video as an example.

I fully understand that it depends on the material used, but as a machinist it is my understanding that any bolt is only as strong depth wise as its diameter. In other words, tapping a hole 1/2"-13 (yes, I am in the USA) 1" deep makes the shear or tensile strength no stronger than tapping that same hole 1/2" deep. Interesting video!

@pontiacg445

2 жыл бұрын

I think it's even less if everything is the same material, and use the standard 7/16" high 1/2-13 nut as my evidence. Theoretically that's only ~5.6 full threads, and once you start adding chamfers it's even less. A "rule of thumb" I've heard is 3 full threads is all that's needed for full tensile, and a 1/2-13 jam nut is right around there, accounting for chamfers.

Interesting. I had not expected that outcome, good to know!

So thorough! Thanks so much for what you do.

As a note: For the shear test of the horizontally printed screw there are two possible layer orientations in the test rig that may behave quite differently.

Also for the stress test, i think using weight and gradually adding them on would be a bit better. E.g. start with decent amount, wait 5-10 mins to see changes, add an additional set amount, wait, repeat till it breaks.

Thank you for this work! I was running into issues with vertically printed M6 screws and nuts that where stripping and splitting at the layers. This research confirms my thought that a horizontal printed screw will be far more helpful. Excellent video!
