Hexagonal nuts as heat set (thermal) threaded inserts into 3D printing

[@stefans.8027]

Hello Igor, i really enjoy your content as an german engineer. These Tests are very helpfull for the design of my 3d printed parts! They are a good addition to the videos of "cnc kitchen"

[@certified-forklifter]

Stefan, is it you from CNCkitchen? xD

[@MyTechFun]

Stefan? Must be very common German name. I think CNC Kitchen author is also Stefan. I am glad you like my content. Regards from Hungarian Engineer :-)

[@stefans.8027]

@@MyTechFun Hahaha! yes, It is very common. Yours and his videos are really helping stop the "guessing game" and start designing based on reliable tests, like we know from metall. Maybe some day Fusion will be able to slice, produce infill and calculate the stress..maybe with topology-optimazation... but i guess they will put that in some expensive modules. Anyhow.. looking forewart to your next video!

Thank you for running these tests and sharing your data!

[@Rouverius]

This helps me understand those forces in very tangible way. Thanks!

[@MaplePanda04]

To insert these, I like to put a matching threaded rod in the drill press, screw the nut on, heat it with a blowtorch, and then press it in. Keeps it nice and straight. For inserts with a closed bottom, remember to make an air hole so the trapped air can escape!

[@TheTranq]

Good idea

[@johnduffy7502]

It must have taken a long time to do these tests. Much appreciated and some interesting data! Thanks (and subscribed!)

[@GMCRaptor]

Brilliant, love how you use your body weight to show force required. ❤

[@qwewer6]

Did not thought that the third type would be that strong.

[@MyTechFun]

I was surprised too. But 2nd may be almost good as 3rd version, if it would be same size. Maybe only 40% weaker.

[@jacoblongwell6419]

Such good info, I would not have tested this on my own, thank you!

[@workphlo]

I loved the intro, great stuff man.

[@haenselundgretel654]

Wow! This is absolutely amazing that those nuts even hold something! Thanks a lot for sharing!

[@woram929]

For range :-). Just like always, well done. Thank you for your efforts, God Bless You!

[@alphaflight101]

I love all the testing! Great source of knowledge! Thanks for the great content

[@ale6242]

woah! amazing tests dude! great information :)

[@bleach_drink_me]

Thanks. Seems I can use the nut in things like fan shrouds where I don't need a lot of strength but maybe have to thread in multiple times for service of the fans,etc. I will continue to use the brass 3d printing inserts when I need a high strength part.

[@WooseungLee]

I don't know I will use this information in someday, but this is great video. Thanks!

[@ronniet906]

Thanks Igor for the recommended insert space dimensions at 6:57, it's very helpful. Note, the idea is to insert the Hex nut at the top end of the 3d printed part (not the bottom end as in your test), then its load capacity is ±30% greater than the last threaded insert you tested.

[@KF7PSM]

Very informative and useful. Thanks for all the details!

[@dedodiy3887]

This was awesome. Safety is number 1 priority tough. Be careful.

[@mrjabal123]

This is what I looking for! Thank you, you helped my Thesis

[@NullHyp]

I’ve been using the injection moulding inserts but after watching this I think I’m going to have to order some of the proper 3d printing inserts

[@NicksStuff]

That would have been interesting to compare the max torque of the three types of inserts

[@aberodriguez4149]

Thumbs up and I had to Sub from what I seen on your videos the time and research you put into your work is impressive, I also appreciate that you share the knowledge. Great video may you always enjoy 3D printing.

[@LMauroFreitas]

Hello, very good video! I also suggest comparative torsion tests ...

[@mmheti]

Why not use a litle preprocessing on the nut? Like mount it on a drill/lathe and make a groove around. IIt should improve the strength making it similar to the injection molding part (or even better.

[@fah924]

Great analysis! One thought/suggestion- consider adding grooves parallel to the standard nut's surface (perpendicular to the threads) to see if thes grooves would increase the holding strength. But otherwise this will really help me decide on which nut-serts to purchase! Thank you!

[@mustafasimsek5055]

Great test sir!

[@BamTehBrent]

Excellent tests. Thank you very much

[@Sky-jq2no]

The third type of insert nut is called a *Double Twill* insert nut

[@MyTechFun]

Thx, I really like these useful comments (too)! I couldn't find that info befre video.

[@NicksStuff]

Idea for a next video maybe: Have you considered inserting a screw in a design? Or maybe just a thread?

[@derekkovari6641]

Vary awesome man just the answer I was looking for thanks!

[@JamesRothschild]

Thank you. A GREAT test. Very useful. Hope you are AOK :-)

[@dekurvajo]

Another con with the hex nut is that you always have extra work with them in cad. And actually in real life cases when they fail is not because they carry that much weight, but when they work as a sandwich, the middle material holds up, and when you tightening the parts together the nut will pulling out by the screw before you can even tighten them. Maybe the strength could be improveb by cutting/grinding some grooves imto them, but then its really just not worth that extra mmount off hassle.

[@avejst]

Great review/Test Like the load objekt :-) Thanks for sharing :-)

[@sidharthap]

Nice video. Tell me, even though you're outdoors how are you cancelling that wind noise. What mic are you using and what sort of software are you using to process the audio?

[@MyTechFun]

Sony ECMCS3 with sponge on it, attached to zoom h1. Audio+video combined in Davinci Resolve free video editor.

[@Xailow]

You should get/make a block and tackle or pulley set up for these tests. You'd be able to test to much higher forces without hurting yourself. Great work though! Very useful info

[@MyTechFun]

Working on safer solution, I need another rod to attach second pulley.

[@Druidus98]

Impressive tests 👍🏻

[@u9vata]

I wonder if using smaller sized hexagonal standoffs (ones that look like a nut, but one end is like a screw for continuation) would be better? The idea would be that "hopefully" the scrend end of the standoff would be melting together with the plastic and thus make it not fall out and the hexagonal part would still work for torque. Likely not so big of a financial gain, but for times when you have standoffs laying arount I wonder if they can be used.

[@LHitstaken]

Hey Igor, interresting Tests! Little tip: use the same scaling for your diagrams. It's easier to compare with each other ;)

[@MyTechFun]

Yes, I noticed that when I uploaded the video. But at least the average values has same scale. Probably I will do a torque test in near future with several sizes. Only it takes few months for items to arrive from China..

[@boblewis5558]

@@MyTechFun Easy enough for anyone to remap your values into a spreadsheet! Personally speaking, when the scales differ so much, I find your method much easier. The maxima and differences can easily be seen to compare across they types just by looking at the scales anyway.

Method #2 is way more accurate since hanging on it makes sure the force vector is aligned with gravity

Hello, you should use a winch or something like that to apply force, it would be much easier but maybe less entertaining ;)

[@Theprofessor1212]

Hi Igor, can you please share the link to your soldering station with digital temperature adjustment on the wand ? I’d like to purchase one as well.

[@MyTechFun]

It is TS-100

[@PoonFlavoredTang]

Looking at your test how come you chose to use the heated nuts on the same surface that a bolt head would also be on? Would there not be tremendous amounts more of holding power by simply having the nut on the other side of the plastic test piece. When I use these I never design my part to use a nut like how you have used them in your test.

[@edgardogho]

Awesome video.

[@andreasvasiliou6453]

Hello! For the hex nut, the adjustable soldering iron that I can find has 200C as minimum temperature and not 180 as you conduct your test, will that be fine for PLA?

[@MyTechFun]

Should work with 200C too, just follow when to remove the soldering iron.

[@rodrigoacuna6366]

Super me ayudó mucho tu video, realmente valió la pena, saludos

[@mostwantedmes]

Really awesome ' imagine used the print part with nylon cf 10%

[@hamood1234fool]

Insert a Hex nut in 3d print then put top cover with a hole the size of nut hole size. Two parts.

[@MyTechFun]

Interesting solution, but depend of the design, sometimes thats not possible.

[@JordanHaisley]

Or just insert it deeper, plastic will reflow over the top and make it significantly stronger.

[@agrxdrowflow958]

Surprising!

[@das250250]

I wonder what would happen if you score a diagonal in the centre of each face of the hex nut which creates a llittle valley for the molten plastic to collect in . I can send you a jpg if you wish

[@u9vata]

With what tool you would score that diagonal? I guess you mean the line scored into the nut would be parallel with the nuts top-bottom faces and go along the nuts faces "circularily". But I wonder that the nut is metal so if there are simple tools that can make that little valley into the metal at home simply?

[@das250250]

@@u9vata I think I would use a mini grinder wheel disc 30mm attached to a drill. Grind a line into the hex nuts sides ( x6) so that when it is pushed in to the plastic there is a valley that the plastic melts into these valleys and ends up a smaller diameter than the outer hex edges. Similar to the score marks on the sides of the other nickle threads you tried.

[@u9vata]

​@@das250250 I was thinking more in lines of: get a thin wire, a hammer and something that holds the nut in place... I could make scars on a nut I tried now on its surface face, but harder when I want to score its side. Mostly hard because the nut itself is pretty small.

[@das250250]

@@u9vata I am happy to send you my idea in picture via an email or app

[@Nolfavrell]

can’t you just insert the nut while printing and print over it? it worked with magnets for me so inserting nuts will be even easier?

[@PabloFederigi]

Excelente! Gracias por compartir!

[@TarahGudmundson]

is it necessary to have 100% infill for the hex nut?

[@MyTechFun]

No, but at least 3 walls.

[@Jazz3006]

Nice video. Is there any chance that you could do a test where you are pulling through the part to take advantage of the increased area of the hex nut? Also, a torque test for the same reason?

[@MyTechFun]

Yes, in near future, but first I have to prepare some stronfer measuring equipment, because my weight is not enough for that pulling test. But this would depend a lot from type and strength of plastic material.

[@Jazz3006]

@@MyTechFun if I may, I would think a cheap and easy way to do this would be a hand winch and a few pulleys.

[@MyTechFun]

@@Jazz3006 Yes, only I need something on the oposite side, where to attach a pulley. But it will be done soon anyway.

[@marshalleng1933]

How would you remove a molded insert like those? I have a project that has a insert that is stripped.

[@OLDJACKSACADEMY]

Hi great video... what soldering iron do you use and where do you get it?

[@OLDJACKSACADEMY]

just seen it in the description

[@funigui]

I don't understand why we wouldn't put the insert in from the opposite side of where the force would be applied, making a shoulder for the insert...

[@MyTechFun]

Depend of the design. Sometimes you need object to hold this pulling force or in both directions.

[@WaschyNumber1]

Nice video 🖖 👍

[@Bobis32]

i wonder how the nuts would fare if you created basic knurling on the outer surface

[@MyTechFun]

Yes, I was thinking about that too, but I wanted to test standard nuts, without modification. Because knurling would be different from case-to-case.

[@Bobis32]

@@MyTechFun it would definitely be a case to case scenario as the angle of the force would change the engagement of the knurling i just felt it might be a good test as the threaded inserts had protrusions to prevent pullout
