Cheap and reliable. I personally use heat to melt one side of the filament to the printed part. It cannot be disassembled but you will never lose a pin.
I use it too. It's easy and very strong. Especially with combination with old 3mm filament that is useless for me other way. Also you can heat ends of pin so it can§ fall off.
I love your videos, but I've got to pull you up on one small inaccuracy. Not ALL living hinges get weaker the more you use them. A living hinge moulded in polypropylene actually gets stronger the more it is used. This is due to the polymer chains becoming more and more uniformly aligned as the hinge is flexed. Of course after about a million cycles the hinge will break down, but most hinges never see that. I'm a former product designer for Nokia and have many patented hinge solutions. All the best, Ricky.
8:44 “Only an industrial designer could be so fascinated by a shopping-basket handle.” I dunno. I am not an industrial designer and I thought it was pretty cool.
As an injection molder for personal care products a majority of the things I molded had living hinges. When grocery shopping my wife would frequently tell me to stop messing with different caps.
I have used 5mm metal pins for butt hinges on a bunch of projects, and they work really well. Needing to purchase pins isn't ideal, but it makes for super smooth motion and can alleviate tolerance issues by using a standard metal piece.
Thanks Angus. I just realised that I don't leave comments often, so aside from liking the video I wanted to say thanks, just in general and for what you do. I greatly enjoy your videos.
A couple weeks ago I designed a Roll Up Chess set, it's on MW and printables. The hinges are quite tiny but because there are eight in a row it works like a charm! And it is doing quite ok as well. I really love incorporating print in place hinges in my design, never thought about that locking one. Great find!
your tutorials are amazing! My design capabilities have come on in leaps and bounds thanks to you. Even desgined and printed my own print in place hinges thatwork. Many thanks!
wow I love your hinge design.. I have been trying to figure out a good hinge design for a couple months now that can do exactly what yours does. Thank You very much.
I used a living hinge in a design (thanks to your previous video). It's two snap fit clips connected by a living hinge. Printed in PETG it works really well. The bracket snaps around two sections of a plastic play pen and stops either of the two sections from being lifted up but allows the sections to be adjusted to any angle thanks to the living hinge. It's stopped my 2 year old from escaping the play pen. I flexed the living hinge more than 100 times and it's still ok. I don't think the same could have been said for PLA but i don't print with it so i don't know and 100 times is probably more movement that it will ever see in its life. I used a 0.6mm thickness for my living hinge. I would have tried a 0.3mm thickness but i use the prusa textured sheet so the first layer gets squished pretty hard.
Oh awesome! I used to live in SJ and it was such a bummer when Fry's went out of business and suddenly I had to order all that stuff online. Very cool that you guys are going to have a brick and mortar option again. Now if only they would open a location in Las Vegas where I live now! =D
@cogspace Yes exactly! Fry's was the next one down the line after Micro Center. I still drive by one of their vacant locations daily (right off 880 in Fremont). That's actually when I found Newegg and Tiger Direct and all those online sites. Never had a need to look online for that stuff before, lol
With the GoPro stand, you could also add snaps so when it goes into its locking state, you have to push the piece a bit more to snap it and lock it in place. Then when you’re done, use a bit of force to unsnap it and slide it back to its rotating state.
I personally prefer print in place hinges. If I want tight tolerances and plan to distribute the files, I like to include two or 3 tolerance tests where people can test their printers and then choose the hinge file that works best for them. And it’s pretty easy to make the tolerance a parameter in the design.
If something needs to lock in position, I use a lot of thin fingers that get compressed by a screw, so instead of one interface worth of friction you have many.
Snap hinge is also fun to print-in-place, don't need bridging or special design, 45 degree overhangs print into each other just fine. If you make the legs thick enough, it won't snap out either.
Weird flex but ok... 😂 Jokes aside, awesome video as always Angus!!! Although not cheap, the new TPU for AMS from Bambulab will also open a lot of possibilities for interfacing living hinges in PLA parts
I was at the taping of Taskmaster AU a while back - maybe season1 -, and Tom Gleeson said his head was scanned and printed in SYD. Then latter - maybe season 2 - there was a tie-breaker where two guests had to guess the mass of TOM's golden head. The contestants were way out but I guessed 2kg and it was 2¼kg - lol -.
Sometimes I use filament instead of screws. Everyone has filament and I just cut it to length. My thought was that filament is stronger then a thin pin that was 3D printed because there are no layers. It can be used in hinges and as a fastener.
Imagine a cylinder. Now change one of the curcular faces to a cone. No shoulder. Stand the only remaining flat face on the ground. Place another modified cylinder (like the first) on top of the pointy end of the first one, but make it concave pointy so they fit together, but with a gap. The second double cone (chevron perhaps) cylinder floats magically above the first by a milimeter. Repeat as many times as necessary, and finalize this magic stack with another flat circular face. Now, connect all these chevron cylinders together with 2mm posts along the shared cental axis. Attach the 1st, 3rd, 5th, and all other odd numbered cylinders to one body, and attatch the 2nd, 4th, etc cylinders to another body. Finally, flip the thing upsidedown and print it. I did this for a box printed on its side once, and It worked out INREDIBLY well, the 2mm post that holds it all together while printing, shears from the torque, but stays around and keeps the hinge moving with almost no slop, but very little resistance. I only came up with it from ignorance. Buttery smooth and shockingly strong, largely because the layer lines of the two bodies wrapped around eachother, and the stesses in the hinge were pushing the layer lones together rather than trying to split them. Sorry if the description came out unclear.
I love high-friction hinges like the ones on laptops. 3D printing these is possible but very hard. There are multiple methods, such as compressing TPU or using a multi-stage plastic snapping pattern on the hinge surface (imagine a flower). I’m sure there are many other ways to achieve this. If you know of any, can you share? i have worked on using these in my designs for years but never got the perfect one.
I've been using a print in place hinge similar to your snap hinge for a very small part that is only 5mm thick. I made a series of them like a piano hinge. Works surprisingly well. Before I had issues with small butt hinges failing due to wall thickness but this seemed to solve it since both pieces have similar thickness hinges. I can't remember which video I saw it though, unfortunately.
I have an idea on how to improve that mini gopro tripod example to effectively auto lock when it gets to that certain rotational point where it can lock. If you design the back of the rounded section of the slot that the cross pin goes into to be spring loaded and printed it with the spring fully extended, the part that rotates would be forced into the channel the instant the part rotated to align with that slot. To get it back out, simply compress the spring by pushing the leg in the direction of the spring. I intend to incorporate this design into a bipod design I'm making.
If you made your GoPro stand square and your legs offset then you hinged legs could fold flat to make your stand compact and then flip them around to make your stand. Although 4 legs aways wobble 🤪
I still wonder how hard it would be to 3D print a Hoberman Sphere 🤔 couldn't find any designs for one, but when I tried to come up with a model to make one myself, I didn't even know where to start.. only reason I'm thinking of it is cause they also has thousands of hinges :p
Great video! I designed a simple TPU living hinge with rigid ABS pieces on each end, using an IDEX printer several years ago, and it impressed a friend who has an engineering company with a $350,000 Stratasys 3D printer with no flexible material or multi-material capability. FlashForge just announced their AD5X printer with a four filament feeder that is capable of filament swapping 95A TPU, which could print PETG parts with TPU live himges.
For those who are printing with a tool-changer, you can make the interface between pin and hole out of an incompatible matterial, i.e. PLA for PETG part, to make sure it does not stick.
While some living hings die a quick death, you can easily find others that have held up over decades of regular use. As a young engineer I learned that the factory has to flex a living hinge through it's full range of motion after they eject the part but before the plastic hardens. I was told that the polymers are oriented randomly after injection but flexing aligns the polymer chains so they can comfortably deform and recover along that axis. My long list of 3D printing exeriments includes orienting a living hinge so it prints last and I can flex it hot off the printer. I'm curiious if it's stronger. Naturally, you'd need to extrude the filament perpendicular to the axis of rotation, not parallel to it, to get the strongest part.
Hi Angus. FYI slant3D doesn't know what he's talking about sometimes and he says stuff that isn't really correct to fit his narrative of FFF/FDM is the superior 3D printing technology when it factually isn't. Every technology has its own pros and cons. Sure he has some useful stuff to share, but I don't fully trust him.

The one I use the most is the filament hinge. Snip a piece of filament and insert it like you would a screw.
Oh that's a really good one! Much more affordable than heaps of fasteners too
I use this as well and tend to use my solder iron at a low-ish temp to kinda rivet in the filament so it cant escape

Really excellent video Angus! I use a lot of butt hinges with metal hardware in my 3D printed props.
Heck yeah. Real hardware is definitely the way to go for durability!
8:43 the trippyness of that compression artefact ahead of the basket handle!!
That might be the worst one I've ever seen on TH-cam.
It looks like frame interpolation. Maybe the video was slowed down?
@@mikkozaitsev It was slowed yeah, that weird artifact only showed up in the rendered video though, super weird!

I'm in San Jose California USA and the neighboring city Santa Clara is getting a Micro Center again! I'm super stoked about that!
Oh no way! That’s great news. Been wishing for one.
@Audiobungalow We had one decades ago but since it closed the nearest one was like 7 or 8 hours away

I'm so jealous of anyone with a Microcenter nearby.
don't apologize for the fascination with shopping cart designs!
Those locking hinges stolen from your local supermarket are a very handy weapon to add to my arsenal.
Thanks Angus! 👍

Those last hinges could really be game changers in some designs
Well… now I know what I’ll be teaching my STEM classes to incorporate into their invention projects! Thanks!!

The snap hinge can also be print-in-place with tighter tolerances than the butt hinge! 🙂

Need more videos like this comparing different ways of doing these sorts of things
Weird flex but ok... 😂

The humble hinge is pivotal. Yes it is.
Very nice, more videos like this showing a lot of possibilities of one thing.
1:00 'precise gerbil hinges' 😅
I was at the taping of Taskmaster AU a while back - maybe season1 -, and Tom Gleeson said his head was scanned and printed in SYD.

Won't the filament become brittle over time and break? Specially with humidity and other environmental factors.
@mttkl I haven't had that problem yet but I believe it's best to heat treat the filament pieces for maximum durability.
0:25 Angus unhinged.
This video makes all your others seem unhinged!
Nice GoPro stand, btw!
nice to watch a 3d printing video without an advert for a 3d printer.
He is advertising the a1 lol

I can't wait to see the future of design. Wild times
Those teardrop shaped bores are amazing. I will use that in other designs not just hinges.
I saw it one of his videos years ago and have been using it ever since. It's a great technique.
Sooo. Awesome! Thanks for your great videos!

I use thick wires instead oft screws. It can be easily cut to whatever size you need and has a smooth surface.
Long live MicroCenter!
I could see also creating a snap-in hinge & butt hinge with indexing.

You can use PP filament for living hinges and they will last just like the real ones
Great video, as allways man!Congratulations Here from Brazil..🎉
very PUNishing video there Angus ;)
The Microcenter chain stores look interesting, but they are not near enough.
1:05 Damn dude! You've got some seriouse ringing on your prints. Maybe you should watch a youtube vid on how to turn up your printer.
Bend... and snap! 💁🏼♀️
“…..pivotal for parts that need to move”
As usual, great video! Unfortunately for me, the nearest Micro Center is 86 miles from me or 138 kilometers.
Living hinges last way longer printed in Polypropylene filament, even if this filament is a hard to print
I'll keep that in mind.
As thanks for your excellent engineering tips I will forgive you for not making any puns about the butt hinge.
How's the unstoppable battlebot going? I can't wait to see the progress!
Makers who don't watch this video will be left unhinged! 😉

3d printer manufacturers should really consider selling common hobbyist hardware and including the samples with the printer.
AliExpress is great for metric hardware.

What filament did you use with the inconsistent colour gradient? Was it home-recycled?
i am currently designing hinges that use helical gears... all for an over engeneered dummy13 posing arm, lol
My most recent hinge was a small box with a lid... i just punched 2 holes in the model, and later jammed a toothpick into them and cut them flush.

Is there any 3d printers that you could recommend that can print with multiple colors that are $210 or less?
I used print in place hinge for a phone stand
All ones...; wow (1.11 million subscribers as of today).
The Locking hinges very old all you have to do is look at pair of pliers
Well, this was a truly unhinged video.
I disagree, it was completely hinged.
For those who are printing with a tool-changer, you can make the interface between pin and hole out of an incompatible matterial, i.e. PLA for PETG part, to make sure it does not stick.
