Brass threaded inserts for 3D printed plastic - Size vs Strength

[@MyTechFun]

At 8:43 I forgot to mention that dimensions were D4.5x5mm (in previous test torque was 1.3 Nm)

[@GeekDetour]

My goodness! You tested SO MUCH cool stuff in this one! Thanks Igor one more time for your dedication, very useful information! Hammering the thread would have surprised me A LOT if it was stronger - but no miracles here, melting is better. Now, it is insane how strong we can get them, if just a few mm longer - even more surprising is how much force our screwdrivers allow us to apply!

[@genegreiner7766]

Wow, Igor! Thank you for putting so much effort into this video. I know you’ve said that videos like this don’t garner a larger audience, but for those of us actually doing 3d designs and projects, this is invaluable information. In my next projects, I will definitely re-consider my choice of insert size. Thanks again!

[@Eduard_Kolesnikov]

Indeed, as I say, it's the best tests that only you doing here, thank you so much.

[@HomoSapiensMember]

super useful video! love how the channel grew since 2019 have you thought to compile and organise all your testing results for publishing in a journal? know you mentioned publishing before... know you also teach at uni so im sure you already thought of this too here's some ideas maybe: Additive Manufacturing (Elsevier) Journal of Manufacturing Processes (Elsevier) Rapid Prototyping Journal (Emerald Group Publishing) Materials (MDPI) 3D Printing and Additive Manufacturing (Mary Ann Liebert, Inc.) Journal of Materials Processing Technology (Elsevier) IEEE Access (IEEE) HardwareX (Elsevier)

[@MyTechFun]

Because of my workplace, yes, I am publishing articles regularly (or my PhD students). Never tried in these ones. Thank you for the list and suggestions.

[@jimrosson6702]

Great video thanks for sharing

[@mornekruger7267]

Thank you for this video! I would love to see more content on threaded inserts!

[@Eric_Wolfe-Schulte]

Definitely looking forward to part 2!

[@MyTechFun]

Actually, it will be part 3 😁

[@DonnyDonnMendoza]

What a huge difference

[@Woloszow]

Love the thumbnail :)

[@PandorusFightStick]

excellent video. i just use hex brass stand offs with a screw at top counter sinked. best method for a full functioning part , if this is possible to do. impossible to pull out

[@riba2233]

@@PandorusFightStick interesting,. thanks for the idea!

[@stefanNT_1008]

Great job, thank you!

I remember watching CNC Kitchen, Stephan told us that these types of inserts are the ones used and designed for injection moulded parts, I remember he started selling some designed for 3D printing, I have never had any issues with the ones I bought from Ali Express, but I haven't used them in a situation where they were subjected to large forces, I bought all 3 lengths for 3mm 4mm and 5mm screws, probably the same pack you yourself bought.

[@MyTechFun]

Yes, these are also from AliE. These are good for 3D printing. The one for injection molding don't have that cylindrical part and the knurling is vertical, not under the angle.

[@flower-space]

Bambu just released their new PPA-CF filament. I would love to see a test of it here in the future ❤

[@MyTechFun]

It will be tested

[@sovahc]

Great info as always. Thanks! Nice room)

[@luke_fabis]

So a key takeaway would be, if you anticipate a gap between an insert and an object, it pays to shim it up until it's approximately flush.

[@MichaelT8710]

I guess this works for pulling out the nuts on models no longer needed. Good videos.

[@MyTechFun]

Yes, they are not damaged. Just don't use the hammering method 😉

[@riba2233]

Great vide0 and nice thumbnail 🙃

[@Tom_makes]

I wonder if is a good Idea to start a print, pause it, insert the heated insert and print over it?

[@MyTechFun]

Not too confortable method, especially, if you want to insert with heat.

[@Tom_makes]

Okay, thanks for the feedback. 😊

[@tinkeringpoko]

That's what she said😅

[@lomborgelev39]

I was about to ask about temp, speed and duration and then you announce it in part 2 :)

[@MyTechFun]

I announced part 3 😁 (this one is 2)

[@RayLenses]

I really needed this video, for my experience the insert length really matters, i do hundreds of insert and the M3 3mm always comes out when people put some Force so i upgraded to M3 6mm so now is more stable. But yes i also have concerns if the speed of threading can influence

[@warmesuppe]

I see what you did there on the thumbnail :-D

[@kimmotoivanen]

It's really mind-boggling that single M3 bolt in printed part can bear human weight (choose threaded insert wisely and truthfully 😅 ) 🤯 PLA (and other filaments too) is weaker than e.g. aluminium, but if we try to design printed parts correctly (orientation, avoiding miniscule features), they are really really strong for cost and easy to create 😉

[@drkzilla]

Are you going to test bambus new super strong filiment?!? I m so curious about it😍

[@MarkokaZjEE]

Szia Igor! A filamentes szponzorációs mondatodról jutott eszembe, hogy jó pár éve Filanora filamenteket használok és szerintem ár/értékben nagyon korrekt (konzisztencia, tökéletes csévélés stb.), magyar termék és úgy látom, hogy te még nem próbáltad. Kíváncsi lennék egy olyan tesztre, hogy egy kis magyar gyártó milyen teljesítményt tud nyújtani a nagyokhoz képest.

[@stevesloan6775]

I’m at 10 seconds in, of course deaper inserts are way way stronger.🇦🇺🤜🏼🤛🏼🍀☮️☮️☮️☮️

[@rsilvers129]

Really wish you compared to printed threads.

[@mastermaker666]

You really should do 100% infill for your tests, that way the print is as strong as it can be and removed as a variable. (is 9 walls at 50% stronger than 5 walls at 50% with a m3 insert, or is higher wall count only stronger/weaker with a higher wall count at this infill % once you get into the larger inserts??? Why not just completely remove those questions/variables so that all other infills/print-variations are likely weaker than the test results?)

[@RentableSocks]

threaded holes!

[@MyTechFun]

Tested in previous video. Too weak

[@RentableSocks]

@@MyTechFun that's interesting, I use M6 threaded holes in my prints all the time and they are very strong, you just need more length to spread the load out

[@stevesloan6775]

The hammer has merit, if you can calculate the inherent strength of fibres created in a nanosecond. Yes it’s a rabbit hole.😑😂😂😂😂
