Hello! This video goes over the design and 3D print of 2 different types of ball joint. The first being a standard two piece assembly ball joint, and the second is a ball joint design that can be 3D printed in place without any support.
These features will be incorporated in some future designs so be sure to stay tuned to see how they will play in!
Also, apologies for the quiet video, that will be corrected for the next one!

Great video .. straight forward and to the point...Still relevant in 2022.... love it.. liked and sub'd

Thanks for making this video! I'm thinking about making some ball joints for my projects. I don't think I would make the ball joint opening the same diameter as the ball. Instead, I think I'd make it 9/10ths the diameter to start with so that it doesn't fall out as easily. The socket opening could be made even smaller if a relief cut was made vertically into the ball to allow the ball to compress a little bit while inserting it into the socket. I think that shrinking the second bigger cut into the socket by 0.5 would help make the joint tighter. Joint tightness can be improved with the application of floor polish to the joint, provided the clearances are good enough.

For sure, main purpose of the video is for the general idea, clearance and fit definitely depends on the type of project you’re doing! Best of luck on the project!

@zsavage1820 2 года назад

you would be surprised as well as to what a little heat gun will do :) did a huge version of the IRON GIANT and the heat gun was so very helpful.. the whole robot was articulated and fun as hell to print...

@yelectric1893 2 года назад

4 cuts could be made to increase flexibility. Still, it’s easier to pop out. Printing in place using folding supports would probably be the strongest and easiest thing to do

@MK-lk7nc 2 года назад

for my 3d balljoint i went with not-printed-in-place and making the base so you can insert the ball / rod in from below, then thread in a ball sized cap with a curved inner surface, and as you tighten that back cap inward, it torques the ball down tighter in the joint, so you can adjust tension. Works pretty great? I had good results with my resin printer and fairly tight tolerances.

@ManarchanyGaming 2 года назад

That's pretty cool. It's a good design as long as the screw is flush inside the joint.

@Vampiric_Kai 2 года назад

That's pretty smart! Gonna keep this in mind for my project.

@MK-lk7nc 2 года назад

@@ManarchanyGaming yeah that was a bit of an issue with the first iteration, then I adjusted the design some to countersink the cap just a bit so there's a little room for adjustment as needed. Once it's mounted on whatever it's going on that cap is hidden. Probably a piece of foam between the cap and the base attachment point would be good ot prevent it from ever coming loose, but I haven't bothered with that yet, it stays pretty snug anyways.

@MK-lk7nc 2 года назад

@@Vampiric_Kai Thanks, hey bonus tip: there's a kind of shower curtain ring you can get, usually called 'roller ball shower curtain rings', and they each have 5 or 6 pre-drilled metal bearings you can take off and use for ball joints, super handy, cheap and very strong and smooth.

@muse_themagic Год назад

I tried to make the one where there is no support, but flashprint keeps deleting the inner ball joint and not printing it. What should I do?

@yusufylmaz6417 3 месяца назад

Great and helpful video. A question i have is how would i then make the socket stay in place for the one printed as one

@engineer3d 3 месяца назад

To make it stay in place during printing ensure there is minimal separation between the “socket” and the “ball” The ball should be designed within the socket but have a gap large enough for about 1 layer line of a 3D printer (approximately 0.1 - 0.2mm) depending on your printer settings

@sarahjackson4858 Год назад

Hi, I was just wondering if your joint design was available to purchase please?

@tonyk680 2 месяца назад

would you have any practical applications for this?

@engineer3d 2 месяца назад

A few applications for this type of design: It’s really good for parts that you want to have motion but don’t want to come apart, 3D printing allows you to manufacture that way which you wouldn’t be able to do using traditional methods. Another application would be if you were to make a design like this in larger quantities it would eliminate the labor hours needed to assemble the parts. Hope this helps!

I’m getting interested into 40k and 3d printing so I plan on trying to make an action figure but Im in 7th grade and have football (we all know that one dad) so I have almost no free time and probably won’t be able to do it, but thanks for the video anyways!

@connorclements3999 3 года назад

Yeah I’ll probably just insert the ball joints into the sliced model and use a ton of force to snap them in

@Loosecannon16 Год назад

Did it work out for your project? My print in place joints got quite loose.

@connorclements3999 Год назад

@@Loosecannon16 no, but thanks for asking! I did make a ceramic plate though!

Is there any way I can download this file (specifically the print in place, I tried to make my own joints but the first didn't move and the second spaghettified, this file would be super useful for me as I plan to make many articulated prints

@engineer3d 3 месяца назад

Sorry I don’t have this design published anywhere and didn’t save on my computer it as it was only for demonstration purposes

@DragonSaur71 3 месяца назад

@@engineer3d Thanks for responding, although, do you have the design for any other ball joints?

@engineer3d 3 месяца назад

I have a few other random ball joints. None that are print in place and stackable though

@ltraltier6009 3 месяца назад

I just want to make an action figure ball socket joint and have enough friction that its poseable. None of this "loosey goosey" clearance bs.

@engineer3d 3 месяца назад

This won’t be the video for that, look into this one, I’ve made a few action figure styles using this kind of joint and had lots of success ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-12lq8g0mia0.htmlsi=vCbSxyc6Pensi7a-

@engineer3d 3 месяца назад

I also have another video that if you played with the tolerance of the design you could get some pretty good friction fits Designing 3D Printable ball and socket joints | Fusion 360 | 3D Printing | Print in Place ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gZUgoZ-w4QY.html

@PlayerA9925 7 месяцев назад

Hello, it has nothing to do with the video, but could you help me with something? I'm having trouble making life-size Murder Drones figures. My problem is with the characters' faces, as I don't know what to do to make them have multiple expressions without having to recreate the face several times, can anyone help me with this?

@engineer3d 7 месяцев назад

You could have the eyes/mouth portion coming from a LCD screen. You could also have multiple facial expressions on different parts of the head so if you want to change expression you can rotate the head, kinda like some Lego characters have. Hope some of these ideas are helpful
