5 Cool 3D Printed Mechanisms

in this video I'll show you five awesome mechanisms you can 3d print at home to show others the wonders of this technology let's get started [Music] how's it going guys Angus here from makers muse I've been in the 3d printing space for quite some time and I've shown many people what this technology can do for the very first time to do that I've always been on the lookout for awesome 3d printable models ones that are only really possible through the layer by layer process employed by 3d printers these 5 models are free to download require no additional hardware and all exhibit really unique movements that you can guarantee will wow someone when you show it to them for the first time many of them have been around the community for a very long time for years actually however if you're very new to 3d printing you might have never even seen them so let's get started with one of the quickest to print the Nautilus gears uploaded by Misha t2 Thingiverse on July 24 2012 this print takes around one hour at 0.2 millimeter layer Heights but you could go even coarser if you wanted to speed things up as an industrial designer I'm quite familiar with the golden ratio and the inherent beauty in objects formed using logarithmic spirals but did you know you can even make gears out of them the gear profiles were generated using a maple script which Mischa T gives full credit to but hey they made it 3d printable which is super cool it prints in parts and they simply snap together afterwards and the Nautilus gives have this spiral shape yet mesh perfectly together it's actually pretty crazy through the entire rotation you do need to be careful to make sure the teeth are meshed at exactly the right points so they can rotate and because of the spiral they actually change ratio smoothly throughout the rotation now I'm sure there's some kind of real-world application for something like this but nonetheless it's an amazing print and out of all the models in this list it's the easiest and fastest making it perfect for a no-fail live demo at schools or workshops coming in next at two hours print time at 0.15 millimeter layer Heights is the famous emmett gear bearing published to Thingiverse february 23rd 2013 Emmet is a prolific designer in the 3d printing space being responsible for many iconic 3d printable models honestly he's an absolute genius at knowing the advantages and limitations of the to any printing process and creating some absolutely incredible models the gear bearing is an awesome printed placed model with herringbone gears arranged in the planetary gearset the parts rotates smoothly around each other however due to the unique tooth structure and they're locked in place and can't fall out it's incredibly clever and works far better than it should as a bearing for printing you need to ensure your first layer is a perfect distance away from your print surface to avoid welding the parts together and you can help free the parts with the help of an pet of a hex key I do recommend using a raft if you're not confident with your first layer height there is no shame in using rafts if they make your prints exceed guys so if you need to do that go straight ahead if you really want to blow someone's mind this model is a great way of doing it just wait for the inevitable but how did you put all the parts together and then you explained well it's because it's a layer by layer process they all form at the same time mind officially blown as a bonus some of you may know I've been a little bit obsessed with reload triangles lately making my own bearing version with these solids of constant width well dolls chickens on Thingiverse had a crack at making a geared bearing version published may 6 2018 to Thingiverse it's a three hour print at 0.15 millimeter layer Heights and I'll be honest my attempt so far haven't been successful it comes out fused and doesn't quite work for me so I might recommend scaling it up slightly but I'll be keep I'll keep testing this file because it looks super cool number three is the Geneva mechanism by me now I don't know exactly why but this simple mechanism has proved mesmerizing for millions of people in the video I made about it however my original design uses hardware and bearings because of this radioactive on Thingiverse decided to modify my original model to make it fully 3d printable taking two hours to print at zero two millimeter layer Heights you do need to use support material for the crank and drive wheel and the movement isn't quite as smooth as the original design but a little bit of sanding will help free it up and you might want to use just a little bit of glue to lock the frame together however it's a fantastic model to demonstrate an intermittent motion mechanism number four is the print in place iris Box remix by Lobo CNC published October 10th 2016 - Thingiverse there's no other way to say that this model is insanely clever a working RS mechanism in a model that prints in place with no additional hardware Lobo CNC wasn't the first to attempt such a design but this is my favorite variation by far you simply print it without support materials and you cut away some little inbuilt supports when the print completes at the base and then it frees up it does take three hours to print at 0.15 millimeter layer Heights and I won't lie this model is a bit of a challenge to get working it's highly dependent on a good print setting good printer and high quality filament plus a healthy dose of luck my attempt in gold PLA failed to free up however this one I prepared earlier in red PLA it's a delicate and challenging print but well worth the effort you never store things in them and last but certainly not least is Emmett's gear cube published to Thingiverse December 27 2013 yes another model of by Emmett I did say he was prolific this design comes in at a five-hour print time at 0.2 millimeter layer Heights so I wouldn't attempt it at a workshop it takes too long to print but as a demo model it's freaking cool there's been gear variations of everything from hearts to faces but the cube is definitely my favorite immediately it's a bit hard to hold on to it and turn but as you do it looks super cool it rotates and starts morphing shapes and it definitely grabs people's attention it prints a separate path and is then assembled using the printed pins just make sure you snap the part in lined up so when it's complete it actually forms a cube and there you have it guys my 5 favorite 3d printable mechanisms can make to show people the incredible potential of this technology huge thank you to the designers for making these models available to the community and be sure to let them know that you're enjoying them if you choose to print them now I would love to know what your favorite 3d printable mechanism is so please leave it in the comments below normally links are disabled for your videos on YouTube however for this video I will moderate them and I will be allowing them in the video comments if they're relevant if you enjoy this video I would love for you to subscribe my aim is to empower your creativity through technology and I look forward to seeing you again very shortly here on makers muse catch you later guys bye
