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 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.
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!
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.
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.
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.
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.
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
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.
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.
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 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.
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.
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
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

I can't down in the comments to ask why he didn't talk about this one

The last hinge I've actually seen for the first time on multi-grip pliers, allows you to adjust multiple levels of jaw openings.

lol "pivital"

My first reaction to that hinge was "ooh that's neat!"
The snap hinge can also be print-in-place with tighter tolerances than the butt hinge! 🙂

Shop kitty spotting! :)
Thanks for the inspirational content, Angus!
don't apologize for the fascination with shopping cart designs!

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.
Makers who don't watch this video will be left unhinged! 😉
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!!

I use thick wires instead oft screws. It can be easily cut to whatever size you need and has a smooth surface.
beautiful, thank you!

I can't wait to see the future of design. Wild times
I'll keep that in mind.

The only one I have used regularly is the one for articulating the Octopus’ legs😂
3d printer manufacturers should really consider selling common hobbyist hardware and including the samples with the printer.
AliExpress is great for metric hardware.
Bend... and snap! 💁🏼♀️
Very nice, more videos like this showing a lot of possibilities of one thing.

Hi! Interesting! About friction hinge is it possibile print in your opinion? Is there a project that is worth it?
How's the unstoppable battlebot going? I can't wait to see the progress!
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.
As usual, great video! Unfortunately for me, the nearest Micro Center is 86 miles from me or 138 kilometers.
Nice one Angus. 🙂
i am currently designing hinges that use helical gears... all for an over engeneered dummy13 posing arm, lol
I used print in place hinge for a phone stand
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.
1:00 'precise gerbil hinges' 😅
Weird flex but ok... 😂

Great video, as allways man!Congratulations Here from Brazil..🎉
I'd love to check Micro Center, but they are not in Canada...
Great video
Hinges are ... pivotal?
We all saw what you did there.
Well, this was a truly unhinged video.
I disagree, it was completely hinged.
What a hinged video
What's the infill type at 1:40?
Cross Hatch
The Locking hinges very old all you have to do is look at pair of pliers
_never_ apologise for the puns!
These hinges are unhinged
bro, stop spamming
@EmilVitus make me
if Shakespeare was ok with puns, we can be too. just sayin.
Oh yeah sure. The answer to your question is I wish I knew cad. Great video tho 😂
