Cool Prints // 3D Printed Compliant Mechanisms

[@JakeMcIvor]

Cool designs! Note that compliant mechanism are often one piece (i.e. monolithic), but they don't have to be. (The core is the flexibility through elastic deformation). Especially for FDM, you can break up your designs in to multiple parts to optimize for strength or build direction.

[@make.anything]

Good point! I enjoy the challenge of designing parts that print in place, but sometimes splitting up a print has clear advantages

I mean 3D prints use very little filament. Generally is 800cm^3 per 1.75mm 1kg roll. At $35 for a roll I would guess at most those prints were $1 - $1.5 each. If I had the models I could be more specific. Basically the cost of SLA

Your “Poly Panels” remind me a lot of Zaks that I used to play with as a kid. Tons of fun!

[@Devsterinator]

They remind me of Atollos! Which is basically this but square, with a socket joint, and another type of piece with a ball on each end, and back to back socket joints in the middle.

[@xaytana]

Can we get a part 2 for compliant mechanisms? Since this video showed more basic mechanisms, I think there should be a follow-up that shows some more complex mechanisms; for example, the elephant shown in Veritasium's video, where there's a lot of compliant parts to the entire mechanism, but there's only a single pivot point at the end of the elephant's trunk that doesn't move laterally. Then maybe follow that video up with advanced mechanisms, like the single piece 2dof vectoring motor/engine mount.

[@DieCastoms]

On your printed capo: Make the white piece just be a pin or tab that sticks out, no hole in it ... make the green piece have holes in it like a belt. Hold it across the strings and stretch around the back and then just hook the appropriate hole on the white pin. this will eliminate the need to 'thread' the strap. I have a capo made in this way that works well.

[@make.anything]

Good advice! If the holes print strong enough that could work much better :)

[@DieCastoms]

How about printing plastic grommets to glue into the rubber holes? Search Google for "Elastic Capo" and you'll find lots of results of the capo I have! They are very inexpensive, like $5 on average. Thank you for sharing with the rest of us, @@make.anything !

Great explanation. In theory compliance mechanisms is the inverse of stiffness. professor Larry Howell from BYU is practically the father of compliance mechanisms.

[@lovecastle7154]

You should be proud of those clippers, such a great design

[@tippyc2]

2:39, yes, it's a 2d geometry, but that's not so you can laser cut it from a flat piece of acrylic. It's so it can be manufactured at a microscopic scale. Most of the advances in compliant mechanisms have come from the microchip industry. They are widely used for clock chips and accelerometers. Microchips are essentially just a series of 2d layers stacked on top of each other.

You can make the ball be in a bistable mechanism so it doesn't fall off, and bonus points if you attach it to the system making it a true compliant mechanism.

[@Hanzedous]

I don't know if you came up with an improvement on the Capo but if you haven't then perhaps you could try a "jar lid style cinch" mechanism on one side as well as the ninja flex tab on the other to keep it the right tension and be able to move it much more quickly. I may be completely off base with this suggestion. I really liked this video, thank you.

what about modular structures, which can be significantly larger than the largest print bed, or concrete infill, which changes the properties of the part significantly. a modular printer enclosure or a concrete infill flywheel can be printed as such.

[@cad3175]

...at last, someone who actually uses their brain and creativity. I don't know how many videos I've seen where there's no useful purpose in the whole endeavour, like blinking an LED or reviewing the latest filament etc etc. Its like we have all this amazing homebrew tech but we are stuck on the how to do it but not on a practical end result. For example: why aren't there many videos on making an automatic door for a henhouse that opens when the sun comes up, there's endless how-to videos on the individual necessary parts but very very few people put it all together and come up with a useful practical end result, it's madness. It's like the mad scientist who's emersed in his thoughts and experiments but never produces anything of practical use, endless led blinking madness. Yes I know there's a place for every methodology but it is skewed badly toward 'how' instead of 'what' ie. What did you mAke and is it useful instead of the usual 'today we're going to review the latest .......' or how to work with this lcd display or that filament etc. That reminds me what's the story with the mindless and useless 3D printing of objects that are of zero everyday use, isn't that ecologically unethical. Did anyone ever ask the question 'What does the maker community actually make'. Isn't that worth asking. Do they deserve that label 'maker', I don't see much making, there's lots of potential energy but not much kinetic. ..rant over and out

Hi Devon, so I have a question/request (sorry I dont have any other way to contact you so hopefully you see this). So I'm getting married soon and I've been looking at rings for myself and nothing online is catching my eye. So I looked into designing my own. And I found something that really intrigued me. An optical illusion called an Ambiguous Cylinder. I'm sure you have seen it before but I thought it would be a very unique design to incorporate the optical illusion into a wedding ring. So I was wondering if you would be interested in helping me design the details into the ring and get it prepared? I plan on getting it printed through ShapeWays in metal. Whether you want paid or not I'm good either way. Would love to hear from you. -Cameron

At 5:27 you can see how the filament has been stressed near the base of the vertical cylinder. I have played with similar designs an have found that by sinking the cylinder into the surface in the slicer rather than building a cylinder from the surface produces much more durable parts. I allows the base of the cylinder to be IU integrated through the outside walls and into some of the infill if present. Is this model 100% infill?

"You could laser cut a sheet of acrylic to make these pliers" Acrylic would probably be too brittle. AvE did a video on making compliant mechanisms out of metal, which didn't work because the metal is too rigid. Material properties are very important to consider for a flexible machine.
