Are 3D Prints Strong Enough?

3D printing is actually very practical. But how strong are they and can we prove that 3D printed object are strong enough?

All prints were printed on Bambu Lab P1S or X1C 3D printers using default slicer settings.

Very cool. Biggest failure is the drywall. A different design might hold more, but in this test it’s not so much the anchor failing as it’s the drywall, which is why they are all so similar.

[UnCoolDad]

You should have tested a factory plug as a baseline. My guess is that it would be about the same as the printed ones.

[AnotherDud]

These don't look like they actually fail though, it looks more the downward force destroys the drywall, considering they all fail around the same point too. I think it's also unrealistic to think you'll place any substantial weight on a single plug, so they can probably take more if the weight is distributed.

Good video though, I've printed 3d shelf brackets in the past, which is sort of similar.

Maybe for the next one, a DIY shelf with shelf brackets attached to drywall with these plugs, or these plugs on a regular shelf and distribute the weight.

Looks like your ultimate failure strength is actually the sheetrock giving way, not the material of the anchor.

I'd love to see you test the large screw in type anchors.

[TheDPrintingGrandad]

Why did you pull down. I think the better test will have been to pull inline with the anchor?

[efficincy]

Hej, interesting investigation you found the limit of the drywall with the given geometry of your anchor.

[TS_Mind_Swept]

As many others have said, it seems like the drywall itself was the main failure point, to which I agree with

[IceProducts]

Your test did not answer your initial question. Without testing a commercial anchor there isn't any comparison provided. Also, from what I see, none of the anchors failed (broke), the surface area was smaller that the structure the drywall could handle for the weight applied.

[pythontest]

It's nice to see that they can hold decent weight but without testing the factory plugs, all the tests show is that 3d printed parts can safely hold 10-20kg and drywall starts failing at around 40.
I was interested in the strength comparison with the factory plugs but you missed that opportunity.

[Bilal.]

Let's be real we shove an extra 2 or 3 more plugs in the wall to make sure the weight is distributed between them evenly. These would be totally worth the money compared to one made by a retailer (Plus customizability for different walls around the world).

What more could u ask for?

[NanobyteOnline]

You missed to test comercial products, now we only know that drywall is failing at ~50kg

[ChristianDybdahlXTR]

I have to say this is absolutely misuse of the stress strain curve.. the dry wall is giving out, they all average about the same due to the geometry of the anker, so the only thing really concluded is that this design in no brittle plastic holdes approximately the same weight around 50 kg, and this is almost flush with the wall and is reduced drastically the longer the screw head is from the wall.

[AdamsReviews]

How thick was that drywall? You really should do a test with different drywall some is as thin as 1/4" then 1/2 and even 3/4 inch....3/4" would probably not fail at all compared to this test.

[Kdaniel]

You could stop at 30kg, 25kg is the official specification for a dry wall (at least in the EU) with a plastic anchor 40kg with a two layers. 30kg / 50kg with a metal anchor. Maybe I will use my old petg now more often :D

[dPrintCreator]

I have had this discussion in a previous video you did, and I see you strongly belief in yourself. Keep on to that. Just, don't hang 12.5 kilogram of lead above your pillow when you go to sleep at night please. I would love to see more of your videos instead of reading you have had a horrible accident.

[jacker]

The pla failed because you didn't print it hot enough

[mishka]

I printed these and every single one failed with the arms twisting off before compressing

[comazine]

Cool and entertaining video, really. And apparently the printed wall plugs are similar to the store-bought ones. They are also specified with a load of 10-25kg depending on the wall. But if you just want to test the plug, you need a real wall or something similar to eliminate the wall factor. Here, the plasterboard wall gives way at an average of 40 kg. That's very interesting, I wouldn't have thought so. In addition, the load in the video is at an angle to the anchor point and therefore does not simulate a suspended load, but a tensile load at angle X. Nevertheless, very interesting and informative.

[daverave]

To answer your question based on this: yes, as it's the wall failing not the printed part in every situation except one.
Nicely made video but this doesn't prove what you think it did.

[krich]

You can literally just use scrap end pieces to zip ties, fill hole, screw screw in. Stripped screw on door? same thing, yes it will hold. Test it yourself. For it doesn't matter if it pierces out the back like this, with how your putting weight on it. It will only truly start to matter for the ceiling.
Point is. Im confident all these work, since its superior to zip tie ends. But with I just said... Average trade worker wouldn't use these. Why carry something extra, that your trash already fixes. For times I need real ones, these wont work anyway. Say 4ft garage ceiling light, ones for this are metal and spread weight load(something that wont happen on a vertical wall). I'm an electrician.
