Print-in-place mechanisms are one of my favourite things about 3D printing. I design vehicles for 3D printing that require no supports and always have some moving parts, usually wheels, but sometimes even working suspension. It's an extra layer of fun, both during the design process and the printing process. Nothing beats the feeling of popping a print off the buildplate and instantly being able to fiddle with it. :)

Hey friend, mechanical engineer here. The third thing that makes this special is that this would be considered a compliant mechanism - there is intentional deflection/elasticity designed into the component to enable a rotational degree of freedom.

I disagree; it’s just a switch with a spring detent The spring is a separate part, and the other two parts are rigid in how they interact with each other and with the spring (aside from the slop in the 3D printed connections) Compliant mechanisms as I understand are single parts that use flexibility of materials to replace mechanical movement. If this counts as a compliant mechanism, then everything with a spring counts too. A watch would be a compliant mechanism.

I finally understand how print-in-place mechanisms are possible. Thanks, Steven!!!

this music is so intense for this omgggg

When Covid started, I was designing some print in place valves with the idea that maybe we could make a fully 3d printed ventilator for 3rd world markets. That project is obviously over but I still think print in place medical equipment would be a cool open source internet project.

holy shit, this is so cool that you actually explained it, and you explained like four or five actually interesting details. the amount of anti-click bait that exists in this video is amazing. bravo

This video gives an insight on what 3D printed part designers are thinking. I also had many hours of designing, including print-in-place mechanisms, assembled parts, and some basic compliant mechanisms. While watching this video, everything sounded familiar and usual to me, and the video felt like it was teaching new people and outsiders. And this made me feel proud, because of how much I've learned. I have a hard time in finding a practical expertise of myself, so such things are important to me.

Can I ask what software do you use to design mechanical stuff? Are you happy with using that software?

@@bylecopanie I use Fusion 360 with Hobbyist license. It's fine. Definitely not as enjoyable as SolidWorks, but it's similar. Quite easy to use. The hobbyist license have the necessary tools. But to be honest, lacks very basic features, like the constrain lists in drawing, and it prefers perpendicular constrains whole horizontal or vertical is possible, messing many things. Even FreeCAD had some features better. But of course, FreeCAD is some kind of brain cancer at the same time. Fusion is much better to use at the moment.

@@Santibag Thank you for your response, I'm about to buy myself a 3D printer (probably Creality Ender 3v2) and I want to design and print some simple contraptions/mechanisms, maybe even a full rc car/excavator in the future, but have no experience in designing for now. Thank you again for your response, It's very helpful.

In addition you could turn on the ironing setting that makes the surface very smooth and more pretty

Stuff like this is the reason I might buy a 3D printer

That’s so cool! 😃

Very nice

Love it

You can make a slot inside that spring, and install a two-position switch there, and on the lever make a pull to it, and you will get a switch) Or use two buttons

That's so cool 🍇

Nice

Great video! Does anyone know what font is used on this part? The consistent width looks like it would solve many of the issues I have with text!

The font is Arial. However, I usually use Helvetica or SF Display (Apple's newish typeface). Arial is essentially a copy Helvetica. Helvetica was designed in 1957 and Arial in 1982 for computers. You can see the difference between Arial and Helvetica by looking at the letter "c". The horizontal lines on the "c" are parallel to the base line for Helvetica, whereas with Arial the horizontal part of the "c" is slightly angled.

A small comment on the video itself, the music is WAY too loud in comparison to your voice, duder.

but can you make it a functional switch 🤔

@TheMachDisk

Жыл бұрын

Sure. You’d need a two filament printer with one of them conductive and then make three conductive tracks going to the toggle and the edge of the wall on either side the toggle locks against and might need to tweak it a bit so it’s applying more pressure in either of the two locked positions but it could work

Naaah fr? i didn't know lmao

The music is annoying.

Go to hardware store to buy much more affordable and very much practical uses of a product.

Unfortunate that it's not functional enough to be an electrical switch.

When speaking please mute music!!!

What the heck is wrong with the super loud and annoying background music? 🙉 Great mechanism tho

Honestly, I do not think this is a good example for a bistable mechanism because the two "stable" states are not inherently stable. Those are just two neutral states between which the movement is restricted to a certain point... after overcoming the potential difference needed to flip the switch, there is not really a constraint on the mechanism except for the end stop, which I would not consider "stable". Nice print in place mechanism though :)
